Quick change EV batteries and ICE car EV conversions.

There are a lot of interesting new developments going on as we (global 'we') look to find solutions to move away from ICE technology and infrastructure in our attempts to mitigate the worst of man made global warming. Two recent articles caught my attention, that of sort of a 'hot swap' technique they are trialing in Norway:


Basically in 5 minutes your battery will be changed for a completely new one (fully charged) in a drive-in automated facility. It adds some interesting possibilities in relation to some of the biggest concerns over EV ownership, that of battery condition over time and time needed to do a charge-up session.

The second is a project currently running in north France, where they are aiming to roll out 'EV conversion' kits to be installed by regular garages (after the correct training etc) where you take your ICE car to become an EV for ÂŁ5,000. That is much cheaper than any current EV and an interesting way to speed up the move away from fossil fuels in relation to personal vehicles. It covers just a few brands currently, but the idea is to roll out more models for conversions as time goes by etc. Fully Charged covered it here on their youtube channel:


These kind of inventions highlight that we have multiple paths to mass EV uptake, and the only thing really holding this back is the fossil fuel lobbies hold over political decisions. Our world is burning/flooding/crop failing, they need to let go of their dangerous old fashioned vehicle for wealth that has been driving that change and adapt to reality. We can do it, we are smart enough, solutions exist. Sadly too many 'me too Jermey Clarksons' exist in positions of influence.

The battery swap is a very interesting proposition. I would like to see more though. Nio has already done 4M battery swaps in China, but that tech is non-existent outside of China.

Both are somewhat old news. I've seen links to some kits in France on this forum about 2 years ago, and Tesla did trial some battery swap 7-8 years ago, and decided against continuing the program.

Battery swap requires some kind of battery rental scheme as you keep on getting a different battery every time. So even if you generally charge from home, you'll need to maintain the battery lease. Renault hasn't been very successful in this country with the idea, so I'm unsure if the wider public will be interested enough to make the swap solution widespread, which it needs to be to be a success.

With 250-350 kW chargers becoming more common, 20-80% charge on an 80 kWh battery takes about 10 minutes, and I expect the hardware installation and maintenance to be significantly cheaper than swap stations. I'd rather the same money was invested in high power chargers than swap stations as I think it will have a much better impact on long distance EV driving in the medium term.

And that is from someone who makes regular (2 to 4 times a year) 750 miles single day trips.

The battery swap thing was a solution in a world where “fast” charging meant 7.4-22kW AC charging and BEVs had 150 mile range. Nowadays BEVs have 300mile range and you can add 200miles of range in 20mins. As 800V architecture becomes more common, 200miles in 10mins will be the norm.

The whole battery swap thing is solving a problem that no longer exists.

I’m very interested in EV conversions. Particularly for classic cars. It’d be great to see more of them. However £5k? What sort of range would you get for that? 30 miles?

Well, you think like that because you are looking at it as a single issue. It is not. Never was.

Battery swap, like battery rental was never only about the headline. Just imagine that you can easily get a "fresh" battery, basically for the price of the charge. A battery that is properly, in a timely manner, conditioned, and checked and you can swap it any time you want for a better, newer, larger/smaller battery. All of this is about the life-expectancy, range, quality, performance, etc. of a battery, and the customers that have "fears" from new products.

The charging or the electricity is just a by-product of the service that the battery swap offers.

No chance. Not possible! A 10kWh battery costs ÂŁ5k. That is without the motor, control circuitry, onboard charger, mounts, etc.

At 4mi/kWh that’d be 40 miles.

Don’t forget a converted ICEV will never be as efficient as a ground-up BEV.

If they’re going to lie they should at least make it believable!

Initial Renault lease model didn't include the option to buy out the lease. They changed their mind based on the market. And the idea of allowing swaps doesn't have to be forever what NIO currently make of it.

I'm not trying to advertise for the success of it. I don't know if anyone can make it work. But the way it's being denigrated here feels like the way battery cars might have been denigrated 40 years ago. Oh look, that way of doing things doesn't work. OK, I agree (see post 3 in this thread), but that doesn't mean that the idea has to be forever wrong. There could be some other applications (the short term battery rental being just one from someone who's not really a visionary) that make it work.

I'm not comfortable with paying 40-50k for the battery in the first place, and having to carry that huge weight everywhere you go. With ICE, it was easy to deal with both regular short distances and irregular long distance travel in the same way. With BEV it's not so as long distance travel has both a cost and an extra weight to carry all the time (note that I don't worry about charge time).

From someone who spent over ÂŁ100k on 2 Teslas, it seems weird to have a comment based on what's been done in the past. Do you think we'll never do better than what's been done to date?
