The battery is the big plus/minus with electric cars: The battery makes virtually every system of the car far more reliable and longer-lasting. The number of moving parts plummets.
But of course the problem is that when the battery dies, so does the car.
My personal opinion is that the solution is to standardize the individual cells that make up these batteries, and make the individual cells replaceable.
Nissan showed a very cool concept which recycled old car batteries as home electric storage, so your solar home would have local, off-grid power storage.
If you look at used Nissan Leafs, they go for a song, because a dead battery=dead car. It's definitely a problem that needs to be solved.
