Powerbank for EVs

[Carbon82]

Reminds me of those portable UPS used for PC and CCTV. While I welcome the idea of having this powerbank in an EV, the additional fire risk has to be taken into consideration too, for those interested.

ZipCharge Go Portable Electric Vehicle Charge Introduced at COP26

A UK startup called ZipCharge introduced its portable electric vehicle charger called the Go at COP26. The Go is a compact, with size and shape of an average-sized carry-on suitcase, and weighs about 23 Kg. It has a 4 kWh (net capacity) battery and can charge an EV at 7.2 kW. However, larger versions will also be introduced, offering up to 8 kWh of net capacity.

In a little more than 30 minutes, the 4 kWh version can add approximately 19 to 32 Km of range, depending on how efficient the EV is. The larger 8 kWh unit needs about an hour to fully discharge and will add roughly 40 to 64 Km of driving range.

The ZipCharge Go is targeted for consumer use and will be available for purchase (pricing hasn't been announced) as well as leased, with a starting lease price of £49 (S$90) per month. ZipCharge plans to begin customer deliveries in Q4 2022.

Basic software functionality will be available to everyone so they can plan and schedule charging, however, enhanced AI software functionality and insurance will be offered on subscription for a small monthly fee which, on average, will save the user £15-20 (S$28 - S$37) per month.

I guess Tiongkok using removable ones also good idea plus powerbank will be perfect for emergency 👍👍👍

Why dont they make this power bank connectable to the EV directly...via an internal cable? Or directly connected in the boot via a fixed connection that is lockable? So that it wont shift around in the boot while the EV is in motion.

You dont have to wait for 30mins for it to charge. Whatever spent power bank can do a one for one exchange with a charged one. Or can be pre charged at home.

The idea isnt new as EV motorbikes are doing this.

I don' know how safe can it be to charge the EV with power banks while on the move. 

Imo, the one-for-one exchange would be a better option. It takes just a few minutes to exchange the flat battery for a fully charged one. 

The power bank would be useful in case of emergency like when the battery goes flat and the next charging point (battery exchange station) is far away. Make sure the power banks/batteries are not like those that burns/cause thermal runaway!

This battery will be available from late 2022.

It will extend NIssan Leaf range approximately 23km.

Battery will not work in Sg.

Lack of economies of scale

Than you will request for another potable power bank on standby to power up the inbuilt power bank and EV. 🤣

Some inventors and engineers are like that, very roundabout way to do things. 

Why not just buy and put a portable diesel generator in the trunk? Run out of electron juice? Just head to the nearest kiosk and top up with diesel in the genset and charge up the EV on the go!

How big is the original EV batt? 

why don't they design EVs with 2 batts, one big one small? The big one is the normal one to use, and recharge when near empty.

then the small one is for back-up if/when needed, with some switch to select using it when the big one is flat. 

yes, it is possible that with this, then drivers will get false sense of security and tend to want to max out the small one too, but it should be useful to offer back-up to those really suay suay never charge enough on a drive (like kanna stuck in bad traffic jams...).

I can think of some who want to save $$$ by buying a unit or 2 to charge it up in office, then go back home to charge their EV...

But hor, there might also be some who want to get free unit, when the owner left them by the car unattended...

I've thought that the days of carrying a spare jerry can of petrol in case of long journeys have become a distant memory from days past. Yet, with the supposedly high tech EVs, we are looking at the possibilities of such absurdity again 😁

The solution to end range anxiety is the development of battery tech, and slowly and surely the next gen of batteries coming will have substantially more range, making range anxiety all but a distant memory.

So bloody troublesome .  
muayhahaha

defeat the whole purpose of pure simplicity.

Stupid isnt it.

no matter what tech, you cant create energy, it can only be transferred.  
maybe the only way is pocket nuclear.
