Cost of Driving an EV

Im still waiting for the solution to a 5 year lifespan to an ev and zero resale. And what you do with a depleted battery when the car is through? Landfill? Rocket into the Sun? And guess what I live in Michigan where we have cold temps and snow to contend with. Whats the recharge life when Im running my heater, wipers, seat heater etc? I know the batteries in my tractor and atvs are not happy in the cold. Not buying til I get good answers. And BTW if its such a great idea why do they have to mandate it? Really tired of mandates.
