To develop
Now electric vehicles generally use lithium iron phosphate battery that principles and our cell phone battery is the same. Charging time division fast charge and slow charge. Ordinary family car, for example, fast charge, then you can fill 70-80 percentage in half an hour, but the charge current is great, there is damage to the battery, if it is possible to slow the charge, then 7-8 hours full. And although there are many known auto companies can charge on 220V electricity, but this is only theoretical, because so much like a battery connected to an ultra-high-power appliances, one cell may have tripped while charging. This battery bottleneck for now, many people have put forward the concept of quick-change battery, you said two for the use. But that is not done by human power, battery on a person with a car is not moving at all, and when the Beijing Olympic Games is a robot with handling, finished in a special charging station where about 34 minutes to change well a bus batteries.
