Abstract:
The present application relates to an electric car and an active discharging module, a driving apparatus, and an electric drive system thereof. said active discharging module comprises a discharging subcircuit, which is connected in parallel with the DC-link capacitor of the electric car, and a first switch, which is connected to an actuating apparatus of the electric car and the discharging subcircuit respectively. The discharging subcircuit comprises a discharging resistor and a power switching transistor which are connected in series, wherein the first switch may turn off the power switching transistor after the actuating apparatus is turned on, and turn on the power switching transistor after the actuating apparatus is turned off. Said driving apparatus comprises any one of the above active discharging modules. Said electric drive system comprises any one of the above driving apparatuses. Said electric car comprises any one of the above electric drive system.
