Can you jump start a car with an EV? While it’s possible to jump start a car using an electric vehicle, it’s highly recommended that you don’t. Electric cars feature two batteries: a large lithium-ion unit for the electric motors and a 12-volt battery for the accessories. This second battery is similar to the lead-acid battery found in petrol and diesel cars and it ensures the main lithium-ion battery can be charged. However, the 12-volt battery in an electric car lacks the punch required to crank an internal combustion engine and you risk damaging it if you attempt to jump start another vehicle. The RAC is pretty conclusive on the matter, urging motorists to “avoid using a hybrid electric car [for jump starting] as this could cause damage”. Similarly, many manufacturers advise EV owners against jump starting conventional vehicles. In the handbook for the electric Leaf, Nissan states that it “cannot be used as a booster vehicle because it cannot supply enough power to start a [petrol] engine”. However, it does go on to say that a conventional engine “can be used to jump start [the] Leaf’s 12-volt battery”. ‘Risk of damage’ In the handbook for the Renault Zoe, you’ll find the following warning: “Do not use your electric vehicle to restart the 12-volt battery in another vehicle. The 12-volt electric power of an electric vehicle is not enough to perform such an operation. Risk of damage to vehicle.” This could extend to unnecessary stress on the 12-volt battery, damage to the DC-to-DC converter, and confusion of the software that monitors the battery. The internet is awash with examples of EV owners jump starting conventional cars, and some owners might risk it in an emergency, but it’s not recommended. While it’s far from conclusive, a section in the handbook for the Tesla Model S suggests you might invalidate your warranty by jump starting another vehicle. It states: “Do not use the battery as a stationary power source. Doing so voids the warranty.” However, there is some good news. Other electric vehicles can be jump-started – you just need to locate the battery. Also, you can indirectly charge a conventional car by using a charger that’s charged using the EV’s 12-volt DC outlet. There are plenty of options available online.

anyone tried using those powerbank around $40 to jumpstart your car before ? wonder if it really works ?

Hey guys!!!!

[Photo/Sina Weibo] At around 3 p.m. last Sunday, a woman was seen jumping into a river in Nanjing. Photos circulating on social media show that the woman was taken care of after being pulled out of the water by a man, but her rescuer was left unaided. The man, clad in black clothes in the photos, was left to try to climb up the riverbank by himself. Internet users later posted the photos on social media, saying, "Everyone was watching the naked woman, but no one lent a hand to the rescuer. It was so freezing." The rescuer is said to be a senior university student currently in a co-op program in Nanjing. Page 2 of 3 A naked woman jumped into a river in Nanjing in east Chinas Jiangsu Province on Jan. 11.

Virtually every driver will, at some point, get that sinking feeling that comes when your car doesn't start. Digging out a set of jumper cables to boost a battery is a rite of passage. Jump-starting a car can be a slightly tricky process, though. The positive and negative terminals of the booster and "boostee" need to be connected properly or the battery can be blown up. Which is, you know, sub-optimal. Over the past decade, a number of devices have come out to help ease the battery-jumping process, including portable booster batteries and even jumper cables that plug into a 12V outlet inside the car. Those plug-in cables will never be connected with reverse polarity, but they might not be able to carry enough current to actually crank your engine. Enter the Michelin Smart Jumper Cable. Instead of the usual color-coded clamps for your battery's positive and negative terminals, the cables are all Michelin blue. Halfway down the cable is a box of electronic smarts. Just put one clamp on the positive terminal of the battery and the other on any piece of bare metal and the electronics will detect whether you've made a complete circuit and illuminate an LED on the central box. When the second battery is connected, the electronics automatically determine the polarity and switch it as needed. A set of these smart jumper cables runs about $30 to $40. http://www.pylonhq.com/products_smart_jumper_cables_tm.php
