16 blade actively cooled after market Leaf battery

An interesting development for the Leaf - our friends at EV's Enhanced in New Zealand have been developing a completely after market replacement battery for the Leaf which includes a fully active liquid cooling system - and not just using heat exchangers as is usually done, the cells are actually directly bathed in the (non conductive) cooling fluid....

Will there be enough of a market for it as Leaf's age ? Who knows, but depending on the cost it would beat replacing an old degraded or failed battery with another one of the same design with the same lack of cooling that will just suffer from the same fate and have the same rapid charging limitations...

Ok, elephant in the room time. Can a Mk1 LEAF justify not just the cost of replacement cells, but also of the replacement wiring and the installation of a complete temperature management system? :unsure:
It's impressive conceptual engineering but I fear it's flogging the proverbial dead horse. What it does highlight once again is Nissan's poor support in not selling replacement packs into the UK market. :mad:

In another 10 years when battery tech has "plateaued" and a new EV has a similar range and usefulness to a 10 year old EV with a new battery things might be a little bit different.
The LEAF has a number of issues, the absence of battery cooling, the battery chemistry, and the rapid changes in safety equipment since it was launched. It is the unhelpful combination of these that means that even dealing with the battery cooling and chemistry leaves a car not suited to an extended life. With the industry trying to move towards self-driving I would question whether cars today will be worth spending half the cost of a new car to update when they are 10 years old.
There's an artificial shortage of both new and used EVs at the moment, exasperated in NZ by local politics. That's encouraging people to try to extend the life of outdated vehicles in ways which normally wouldn't make sense.
I agree with the posts above - the Gen 1 LEAF would be lucky to get two stars from Euro NCAP now. Apparently we now "need" (from a safety point of view) AEB, ACC, BSD, TCA, LKA etc. But personally I dislike a lot of the modern electronics, and my most recent experience of an MG4 left me much preferring the Gen 1 LEAF as it currently is - but that is just me and not what it appears consumers are being told that they need/want. More realistically I'd notice a lack of space compared to the MG4 and would worry about existing wear and tear and any corrosion. I'd also be concerned about the ongoing support for issues such as major control modules (TCU etc).
I would suggest that the price must be limited by the differential between the price of a LEAF with a poor battery and a new MG4 SE SR. In the UK those seem to be £7k upwards and £26k currently, and in the EU a Dacia Spring at £18k or less. Hard to see anything more than £10k which is about the current "value" associated with a used 62kWh battery when they are available.
