An onboard computer decides when to use the gasoline engine, when to go electric, and when to use a combination of the two. If you go over 24km/h, when you step on the gas pedal(油门), you are telling the computer how fast you want to go.
The electric motor recharges automatically(自动地)when braking. And when driving at certain speeds, the gasoline engine not only powers the car but also recharges the batteries.
When you use the brake, the electric motor acts like a generator(发电机) to produce electricity to recharge the batteries. Batteries will last for around 200 000 miles.
