A large part of the problem with EV batteries is that they lose some of their capacity with each cycle of charging and discharging. Lithium-ion batteries in particular can be damaged by the heat generated during rapid charging or can have their capacity diminished by being drained too low.

To get the most life from your EV battery bank, charge your batteries slowly and try to keep your batteries between 20 and 80 percent charged at all times. Keeping your EV in this sweet spot can help avoid overheating which will reduce its ability to hold a charge over time and delay the costly replacement of your battery packs. 

The price of replacing some EV batteries can be as much as $20,000 or more, making such an operation cost-prohibitive for many owners. Innovations may be on the way, however. EV and battery manufacturers like Tesla and BYD are working on ways to minimize wasted space in EV batteries and integrate the fuel cells into the structure of the vehicles themselves, minimizing heat generation and battery degradation over time.
