As requested by @Volvobrick Started even before I got the GLC Coupe. Was already looking at the Tesla for that first bite in EV, BUT a few things were not in order: 1. Infra, 2. Nascent stage and tech on all fronts, 3. Limited models to compare 2 years later, after much shopping and research, with the infra much improved, I went for it. These were the contendors: 1. Tesla Would have settled for it save for it being commonplace like the Rolla and not having a dedicated showroom (now have) put me off. Also, the feel and overall façade of the T3 was a put off. Literally an iPad on wheels 2. Ionic 5 This was also on the radar but there were limited units on the road and somehow, the design and cues just did not fit in. I could see how it had an appealing design, but was quickly taken off the list. Then, I went upmarket and here were the contendors: 3. Taycan Loved it at first sight, test and what was given. It had that oomph and all and was close to making the cut, but then my senses got to me…to pay $600/$700 plus k for that……into the bin. 4. EQC 400 Sure getter for me. Loved the design cues, overall feel, and with the GLC, it had the same feel as I was used to. Almost plonked for a used on, with 14k on the odo, but someone beat me to it. Fate, I guess......... 5. EQE 400 Went down a couple of times to have a look, but unit was not homologated as yet, and no test units avail, and then when the price was revealed, too hefty a tag for me. This would be my go to in future Then, the GLC got grumpy and I had the tyre blowout🤑..bitch…that was a sign. Car was already listed for sale, and had a few offers, but then this particular dealer (deals with EV only) sent me a msg. I did not reply, but 2 weeks later, I did reply and then voila: 6. i4 EV40 There was a unit avail for me to take, but was beaten to it. Not disheartened, I waited and then just after the blowout, dealer called me that he had the Portimac Blue unit and was to come in later. COE went up (105k) and I thought, there goes the price. Lo and behold, price maintained. Did a visit, and he allowed a test, and I placed my deposit on the spot. Car only has 1.4k on odo. Used for mgt to test, I was told Collected the car after my Iceland trip, and there was a poignant note to this, as when I was in Iceland, I truly saw the effects of global warming. Right before my eyes, I saw a breakoff of an iceberg from the Glacier and to me, Global warming is real… so that kinda edged me on. May be a mall part, but still a part, although some may say EV is another MotherEarthFUGGER ahhahaha So to end it all, those going on this journey, these would be your considerations on the EV choice: 1. Price – this is clear. Has to fit the pocket. Savings downstream are massive, but capital costs upfront. Look at BYD, they are promising 2. Charging – study the charging infra around your area. My area has no shortage of charging at all and suits my lifestyle 3. Range anxiety: This WILL be an issue, but will be gone after a week or so. Car can go to low 20% and still have range of 100km. Same as ICE 4. Savings: Somewhat negated by road tax BUT still save abt $3k/annually as monthly charging is around $150 vs Petrol previously $500...ccb PAP That’s all I have to say for now, but as and when I do have any inputs, I will add on. Others, please feel free to chime in. For charging and sites lobang, go here:

Is Vartan brand good? Never heard of it. Only heard boch. My current car is using Panasonic Q100L. The workshop I am going said they only have varta EFB Q85 Any reliable battery workshop in the west to recommend?

So far not experienced it. My s9+ battery was swapped earlier this year and it wasnt swollen.

I was almost locked out of my car after dinner and tried multiple times before the key finally worked. I also realised that the key in my fob is a dummy key and I cannot unlock my car door using the traditional key lol. I've had to replace the CR2032 battery twice in less than one year of ownership. The previous one was a Mitsubishi branded one which lasted slightly more than three months. Right now I'm using this cheap $1 Maxell one which I bought from a random convenience shop that was still open last night. Three questions: How long does the battery in your key fob usually last? What brands to use for car key? Duracell? Energizer? Should I be concerned that the mechanical key inside my fob is a dummy one?

Source: https://www.hardwarezone.com.sg/tech-news-nissan-to-launch-first-ev-with-solid-state-battery-by-2028 Nissan aims to launch an EV with all-solid-state batteries by 2028. The company shared the goal when unveiling its prototype production facility at the Nissan Research Center in Kanagawa Prefecture. The prototype production facility will also be the site for studies on materials, design and manufacturing processes. A pilot production line at its Yokohama Plant is planned for 2024. Nissan believes all-solid-state batteries will be a game changer as they boast twice the energy density of lithium-ion batteries. In addition, all-solid-state batteries have significantly shorter charging time and incur lower production costs. The company claims all-solid-state batteries can reduce prices of battery packs to $75 per kWh in 2028, and to $65 per kWh thereafter. The company announced in November 2021 that it will spend $18 billion over the next five years to accelerate the electrification of its offerings. It also announced four new electronic concept vehicles.

This informative video explains the real world challenges that electric vehicles are facing, which is not about the cost, battery technology and range.

Hi all, Going to collect car soon. Some newbie questions. 1. Will the warranty void if I upgrade the kia dashcam to other brand with battery pack connected to fuse box from outside workshop? 2. Will the warranty void if I upgrade the car battery to higher capacity battery? Any recommended brand and workshop? TIA

https://www.thedrive.com/tech/43155/ford-purdue-cooling-patent-could-charge-evs-as-fast-as-gas-station-fill-ups <Ford, Purdue Cooling Patent Could Charge EVs As Fast As Gas Station Fill-Ups Heat management is crucial to faster charging, and this patent has a built-in way to keep things cool. Battery science is a pretty undeveloped field, which is why we're still using lithium-ion instead of ultra-efficient metal air or sodium chemistry. During the period when burning fuel to generate power was always the easiest option, there wasn't a motivation to make storage a priority and when it comes to EV charging, from infrastructure to materials and methods, we're in the absolute infancy of what might get done. This is why it's extremely cool to see Ford working with Purdue University on a potentially game-changing charge cable. The patent's still pending and this isn't in the production stage, so it'd be years before it could be rolled out. But Ford has shared details about the research, which has come up with a solution that could drastically cut EV charging, Ford says, maybe even down to the same amount of time it takes to fill up a gasoline car. Before I dive into how it works, let's discuss the basics. One of the things about charging a battery, as anyone who's ever plugged their phone in on a warm day will know, is that it gets hot. And as you'll also know from plugging the charger in, it's not just the battery—the cable, the adapter, everything gets real warm because of the current flowing through it, especially as you increase that voltage for faster charging. You can lower how hot parts of it get by using higher-grade, less resistant materials but not only is there a financial cost to that, it also generally means you need rarer stuff and it's not like metals and minerals we're using for technology aren't already a problem. The heating up limits charging and causes the equipment, on the battery and charger side, to degrade faster. So one key to improving charging—which is to say, making it faster—is managing that heat. Ford's partnership with Purdue has come up with something pretty interesting, which is a cable made with liquid cooling built into it. PURDUE UNIVERSITY Liquid cooling is pretty fancy, in a battery—AMG is rightly pleased with its direct-liquid-cooled energy store that's basically apeing the Mercedes F1 battery—but it doesn't need spectacularly precious elements. Building it into a cable is clever enough in the first place, given the cable needs to flex but Ford and Purdue's research has also got a stage smarter than anything else around so far. The cooling agent that the cable uses switches between being a liquid and vapor, which is a heat-reductive process. Like the reason humans sweat, when something vaporizes it takes heat from its surroundings, wicking the excess away from the charging cable wires. That also doesn't require the liquid to be pumped around in order to circulate its heat reduction capabilities. Purdue mechanical engineering professor Issam Mudawar led on the project, alongside Ford's engineers. In Ford's news release, Mudawar said that a prototype cable should be being tested within the next 24 months, in order to work on seeing how much difference the cable makes to vehicle charging times and how much it increases potential current. That's very exciting, even if it's still a long way off being a production concern, especially because this isn't Ford saying it has a new type of proprietary plug, this is actually a new way to use cooling technologies altogether. Although there was quite a lot of bombast in Ford's release about this to say it could bring EV charging times down to equivalent to refueling, that bits in the handwave phase at the moment. We don't know how much it will actually improve charging times or if the system is, for instance, robust enough to withstand thousands of charge cycles—that's the point of research, that it's still getting worked out. But it's a nifty innovation and it'll be interesting to see where it goes.>

My Hitachi car battery in my Honda Shuttle Hybrid died on me a few days ago. Sadly, it lasted only 1.5 years, and could not start my engine after I WFH for a few days. Luckily, I managed to get a nice guy to come down within 20 min to re-start my car for $25. Thereafter, I went to a car workshop to change to a new battery. Initially, I wanted to install the cheaper advertised Amaron car battery ($70). However, the technician looked at my hybrid engine and recommended the Varta Blue car battery ($110), which he said was specifically for the start-stop engine. He said it could easily last 2 years. I thought Amaron was the hottest brand in the market and I had a good experience with it on my Vios. Any feedback on the Varta battery? Unfortunately, the small battery tray in Honda Shuttle Hybrid meant that I could only install the smallest Varta Blue battery even though I wanted a bigger one for only $10 more. I checked around several online websites and Varta batteries easily cost 50% more than Amaron batteries of similar capacity and current 🙁

A quick question here for the experts in this forum. Idle the car to keep the battery healthy or really need to drive it around the blocks.

Hi all, Car battery just went dead. Which car battery provider do you call? There are many choices and ads when you search by google, but would appreciate to know your reliable car battery provider based on your actual experience. Thanks in advance.

https://www.caranddriver.com/news/a33435923/toyota-solid-state-battery-2025/ Toyota built a working solid-state battery-powered prototype vehicle that was supposed to be shown off at the Olympic Games this summer. Toyota is partnering with Panasonic to put solid-state batteries into limited production in 2025, but don't expect them on your Toyota vehicle that soon. For one thing, the automaker still needs to solve the problem that plagues solid-state batteries: a short life span. Toyota has chosen to focus on hybrid and hydrogen fuel-cell vehicles as the cornerstones of its green strategy, but that doesn't mean the automaker is forgoing an electric vehicle altogether. In addition to an EV crossover coming from the automaker and its partner Subaru in the near future and a lineup of six EVs (some of which are pictured above), which are likely to land in China first, Toyota is currently working on a technological breakthrough that will reach far beyond its use in an EV: the solid-state battery. Solid-state batteries charge quicker, last longer, and have a greater energy density. That means that a vehicle outfitted with one can go farther than it could with an equal-energy lithium-ion battery pack. Toyota was to show a working prototype of its solid-state battery at the 2020 Tokyo Olympics. That, of course, has been rescheduled to 2021 because of the coronavirus pandemic, but Toyota still wanted to share how far it has come in building its own battery pack. Speaking with Automotive News, Keiji Kaita, executive vice president of Toyota's powertrain company, said the company has a working prototype. However, because of safety and durability issues, it has yet to harness the true potential of a solid-state battery. One of the biggest issues with solid-state batteries is their short life span: they tend to fail after repeated charging. "To counter limitations, we're looking at how we might adjust the anode or other materials. We are trying to reduce disadvantages that are found," Kaita told Automotive News. The automaker, along with its partner, Panasonic, is focusing on a sulfur-based electrolyte that is said to allow for a more efficient ion transfer between the electrodes. Still, Toyota needs to figure out how to create an electrolyte that won't become deformed by simply charging and discharging the battery, leading to pack failure. Samsung is working on the same issue, but instead of replacing the electrolyte, it's replacing the lithium anodes with a silver-carbon composite to reduce the destruction of the electrolyte while the battery is being charged. Kaita notes that Toyota's breakthrough in this area might come from new materials or a new design. So sulfur might not end up being the solution Toyota is looking for in the long run. On the manufacturing end, Kaita said that because the cells need to be produced in an ultra-dry environment, the automaker is currently producing the cells in compact booths. Workers reach in to work on the cells through sealed rubber gloves. That doesn’t lend itself to large-scale manufacturing. Still, Toyota says that limited manufacturing is on track for 2025. These batteries will be expensive, but if the automaker and Panasonic can figure out how to mass-produce solid-state batteries for its hybrids and future EVs, it'll be a huge jump for all battery-powered electronics, let alone electric vehicles.

YUKI MURAKAMI, Nikkei staff writerJuly 21, 2020 00:29 JST KYOTO -- Sanyo Chemical Industries' rechargeable battery made almost entirely of plastic is now powering an unmanned submarine by Kawasaki Heavy Industries in a test run, with the promise of doubling the vehicle's operation range to 16 hours. The trial presents the first commercial use of the all-polymer device made by Sanyo subsidiary APB. The battery, whose electrolytes are also made of resin, lasts twice as long as its lithium-ion cousin and boasts cheaper production costs and greater resistance to fires. Kawasaki's autonomous underwater vehicle is designed to inspect oil pipelines and other deep sea equipment. Due to the nature of the work, an internal battery would be subjected to high pressures. The all-polymer battery can withstand depths of more than 3,000 meters. APB's battery can power the vehicle for about 16 hours on a single charge, up from roughly eight for a lithium-ion battery. Mass production for the all-polymer battery is said to cost 90% less than for a lithium-ion counterpart due to the simplicity of the manufacturing process. APB, is setting up a plant in Japan's Fukui Prefecture. Full-scale production will be ready around fall 2021, with sales to begin before the fiscal year ends in March 2022. The aim is to develop a business worth hundreds of billions of yen (100 billion yen equals $934 million) within five to 10 years. The operation will focus on stationary power storage for buildings, but batteries for undersea drones have become feasible as well. APB has raised roughly 9 billion yen from eight investors through June, including trading house Toyota Tsusho and energy major Eneos Holdings. Both Nissan Motor and Sanyo have licensed polymer battery technology to APB to accelerate development.

Hello admin and mods, can we have a dark mode or dark theme option to choose from? Thanks.

So since this topic is here to stay, I think instead of debating who is right and wrong, I think we should be prepared if there is something bad happening around us. I used to be from the Navy so I have learned some basic fire-fighting knowledge. I never fight a real fire before, luckily. So all the stuff I mention is from my understanding and with the help from google. At least 34 cases of PMD-related fires this year. There have been at least 34 cases of fires involving personal mobility devices (PMDs) so far this year, with two incidents over the last two days. Read more at https://www.todayonline.com/singapore/least-34-cases-fire-involving-pmds-year It is believed that lithium-ion battery fires are some of the most difficult fires to suppress. You can see the video here. and for a small lithium-ion battery, it can already cause such big damage, imagine you have like 10kg worth of lithium-ion battery. How to extinguish a lithium-ion battery? To prevent me from "oversteer", let's dive straight to the topic. Despite their name, lithium-ion batteries used in consumer products do not contain any actual lithium metal. For lithium fires, only a CLASS D COPPER POWDER EXTINGUISHER is recommended. The minimum equipment required includes eye-protection, respirator, rubber gloves, etc. If other combustibles nearby catch fire as well as a result of the lithium fire, then we need to use appropriate extinguishing agents to douse the secondary fires. Needless to mention, it is important to address each type of fire with the appropriate extinguishing. So as you can see from the chart, Class D fire is to tackle combustible metal. It is very expensive to actually keep a class D fire extinguishers at home compared to the dry powder extinguishers. So is there any other way to put out class D fire? since Li-ion contains very little lithium metal that reacts with water. Water also cools the adjacent area and prevents the fire from spreading. Research laboratories and factories also use water to extinguish Li-ion battery fires. But I think this part is subjective. If there is smoke from the lithium-ion battery or there is an initial flame, I think water will be useful if it has already ignited, I don't think it will help. @carbon82 can help me with this. haha. Should I get one Class D fire extinguishers? Some of you might not have bought a fire extinguisher before. A normal dry powder ABC extinguisher is about $25 at lazada. So who will want to buy $620 dollar of extinguisher and stand by? If our government can invest 7 million on the return scheme of PMD, I think they should consider having extinguisher mounted at all HDB staircase or something. And I think it is good that maybe whoever is buying and registering a PMD, they need to go through a 1-hour fire fighting session or something. If they carry the risk, they must minimize the risk too. make the buying process a bit more troublesome, so those young punk will find it a hassle to own one. That's my thoughts. I never win TOTM before thou. 🤣🤣🤣

A documentary video from CNA Insider showing us about the explosive facts of overcharging a bargain-price lithium-ion battery. This applies to mobile phone and other batteries that are lithium-ion. But PMD' owners, please take note. You guys have higher risk involved. Due to the sheer size of the batteries. So you must be wondering, how dangerous it can be right? CNA Insider has gotten a professor from NUS, Dr Palani Balaya to demonstrate how overcharging lithium-ion batteries can be dangerous. So here's a lithium-ion cell This cell should take 3 volts to charge. Let's ramp it up to 5 volts! ⚡️ Okay. Something is growing. . . For those who are watching the video, fret not. No need to move back from your screen. Do you notice the smoke? More smoke. And it goes. . . Kabooz!!!! Oh my goodness!@#$%!@#$ So imagine this is multiplied to the size of a scooter. To avoid all these mishaps, please look out for battery certification. For the full video, please watch from here.

A post about a customer who refused to pay after a battery replacement workshop rendered its services has gone viral online. Spotted on its own facebook page, FastFix Car Battery Replacement Service explained how the whole issue came about. It wrote in its post that its client, Mr C, reached out to them saying that he needed help as his car could not start. After listening to the symptoms the car showed( car still cranks and aircon is not as strong as before), the workshop concluded that it needed a new battery. However, upon reaching Mr C, whose car was parked in the CBD and hence the need to pay for ERP charges, the guys from FastFix realised that it wasn't the battery that needed replacing. Concluding that there was nothing the guys from FastFix could do to help, Mr C was then asked to pay for the labour fee that had been pointed out before in their Whatsapp conversation. Unfortunately, Mr C disagreed and refused to pay the $50 that they had agreed on as nothing has been done to his Kia. There was not much FastFix could do which probably prompted them to 'share their story' of the client on their facebook page. Here are some of the notable comment in the post.

Installed iRoad X9 in my car last year. Had set the voltage threshold to 11.8 V. Went for a vacation for 7 days. When I came back I could not unlock the car with smart key and could not start the engine. The iRoad had drained the car battery. So it looks like after it detects 11.8 V it does not disconnect the power. It still draws power from the car battery. Lesson learnt. Remove the power plug and USB cable from the camera if you are going on vacation. I don't know which workshops can install the battery pack that is discussed in some forums.

Hi All. I am interested to find out the price of replacing the hybrid battery for our vehicle. How much does it varies from brand to brand? Anybody had theirs replace before?

2020 Kia Niro Hybrid launched in Korea this March. With battery and electric could this SUV? crossover? hatchback? be the most practical SUV we can find today? Let’s check what has changed inside & out and test drive it. 2020 Kia Niro Hybrid 4,355x1,805x1,545x2,700mm 171.5x71.1x60.8x106.3 in. 1.6gdi Hybrid Total: 141hp 1.6 Gdi - 105hp @ 5,700 | 32kw electric motor - 43.5hp 6 speed DCT Competition: Hyundai Ioniq, Toyota Prius https://youtu.be/EqR5UNprPAo

Any recommendations for the most competitive price Amaron Q85 battery for the rides with the start stop function?

Guys, Anyone remember who is Ah Siong from Hankook previously? He was the head Mechanic manager from Toh Guan branch previously. Believe many guys here trust his skills and experience in tyres and battery. Where is he now?

recommended by the local Varta battery distributor to two shops in the west. one shop offered me a varta battery of the capacity i wanted but the battery has no indication of the Varta brand on the body. It has a BMW marked on the body presumably it is used on BMW car but mine is not a BMW but the capacity is suitable for my car. the battery does not come in a box as most new batteries do. it is wrapped in cellophane plastic. It looks very much like a new battery to me. the boss said is a new battery and it just came in a few days ago. he said could check the barcode but when I scanned the barcode the search ended with no result can this be a new battery as the shop is recommended by the local varta distributor

I am looking for a car battery of 850 amp of the brand FIAMM and VARTA, Appreciate if you could let me know the retailers of the above brands. Thank you.
