电动车，怎么充电这么快？

Fast chargers push in more voltage and current. 快充桩加大电压和电流。 The battery drinks electricity like a big cup. 电池像大口喝水一样快速进电。 Normal charging is slow and gentle. 普通充电慢一点，也更温柔。 Fast charging fills the battery in minutes. 快充只要几十分钟就能充满大半。 The car keeps the battery cool while charging. 充电时，车会给电池降温。 Too much heat is bad for the battery. 太热会伤害电池的寿命。
