Nissan LEAF Battery Module Teardown Videos


Ben Nelson continues his very detailed dissection of his LEAF battery modules in two more videos.  Great stuff, and if you missed the first parts, check them out here, when he went to pick them up, and when he started taking them apart.

what’s the compacter unit with resister?

Looks like a lot of room for weight reduction in that pack. Maybe they could use plastic in place of some of those metal base plated and tie downs.

And what’s the center terminal on the module? I’m assuming BMS.

anyway good video and thanks for posting it.

For anyone interested in another app for Leaf cells. I did an article here on inside EVs about using it as an energy storage system for a Home solar PV.

Check it out here:


Using plastic components is not very “green.”

The big thing I take away from this video is looking at that lump of 24 modules. Basically, that is 12Kwh of storage right there. That is roughly 40 miles worth of driving for a Leaf-sized car. In fact, that is really not much larger than a 1st generation Toyota Prius battery pack (which I’ve had the pleasure of replacing once) And what that tells me is there is really no good reason that every hybrid vehicle made today shouldn’t have a good 40 miles of EV range. And there is also no reason that something that size can’t be placed somewhere in the car that doesn’t consume cargo area.

Great observation, David! I would have loved to see this video back in 2012 when the Nissan LEAF battery pack was all over the news. Still a good video to watch. I have seen some other material from Ben Nelson, and really respect what he is doing. Great stuff.

Yeah, especially in a large car or large SUV, there should be plenty of room for a 30 (or in a large SUV or Large Truck – 50 kwh) for a PHEV with 50-90 miles all electric range, and seeing as battery prices are 1/2 what they used to be, there really is no reason not to do it at least in the premium pricey segments of the market which are not quite so cost constrained. They had a beautiful hybrid system in the Caddy Escallade a few years back, but then they stupidly discontinued it after all that engineering work, when they should have placed a 30-50 kwh battery in it. They’d have that segment of the market all to themselves, and would have for years. Now on a large pickup truck, you could put the equivalent of 2 Leaf battery packs of cells between frame rails, such that the battery wouldn’t take up any extra space at all, and you’d have a 48 kwh PHEV with an AER of around 100 miles, pretty good for a large truck. Most work days, the truck would do the vast majority of its work gasoline free, and only heavily driven trucks… Read more »

But then You start to realize that hybrid is just that. Hybrid.

99,5% of trips on pure BEV is not end goal here.

Just enough of it to bring up MPG to whatever environment government agencies require.

If price and weight of batteries comes down… there wont be “classic” hybrids any more! BEVs or gas-extended EVs, will rule.
(Assuming costs of engine+battery is lower then cost of ICE)

If 99,5 percent of trips are all electric, that is good enough for me. I am not a perfectionist.
