Like gas, batteries store chemical vitality and might cause burns and poisoning in occasion of an accident. The problem of cost time could be resolved by swapping discharged batteries with charged ones; nevertheless, this incurs extra hardware prices and may be impractical for bigger batteries. Moreover, there have to be commonplace batteries for battery swapping to work at a gas station.
