Battery
EVs face significant battery-related challenges:
Driving range.
Most EVs can only go about 100–200 miles before recharging—gasoline vehicles can go over 300 miles before refueling.

Recharge time.
Fully recharging the battery pack can take 4 to 8 hours. Even a "quick charge" to 80% capacity can take 30 min.

Battery cost: The large battery packs are expensive and may need to be replaced one or more times.
Bulk & weight: Battery packs are heavy and take up considerable vehicle space.
