Oui, vous avez raison. ;-) However, for a long as I've followed EVs (and that's over 40 years) the battery has always been the main source of reliability problems. Almost every EV I've seen advertised for sale has said "needs batteries." In those days, lead batteries could get away with much simpler BMSes (or none), so that's what they got. Nothing prevented battricide in those EVs. They might replace the battery once or twice, but it wasn't long before they decided that EVs just weren't any match for ICEVs in reliability. It's better today, mostly because advanced batteries REQUIRE smart battery management systems. Still, even folks who haven't followed EVs know intuitively, from their experiences with laptops and mobile phones, that the battery is going to have a definite (and perhaps unpredictable) life.

Exactly! battery leasing with guaranteed performance removes much of that anxiety. I may be naive to think this will actually happen, but it seems to me that the longer your battery lasts, the better the lessor makes out. That SHOULD create incentive for them to push battery makers to develop the most durable, cost effective battery possible. This is completely different from the model followed by the makers of most rechargeable appliances today: build it as cheaply as possible and let the customer worry about how long the battery lasts. Further, the quantities the battery lessors purchase could help to improve economy of scale. That's good for even folks who buy their batteries. As I see it, in an ideal world, every EV would use pretty much the same type of battery, just with different configurations (voltage and capacity) - just as today in an ICEV you can use almost any supplier's fuel, oil, tires, starting batteries, etc. With interchangeable batteries, or even interchangeable modules, just about any entrepreneur could jump in to build and lease a better battery. That would be even better for EV owners. But I doubt that that will happen. I expect the automakers will do whatever they can to lock EV buyers into the "fuel" (batteries) they supply.
