The invention discloses a starting circuit for an electric automobile, the electric automobile and a starting method of the electric automobile. The starting circuit for the electric automobile comprises a switching device, an auxiliary load module and a power module. The switching device comprises a first contact, a second contact, a third contact and a fourth contact. The first contact and the second contact are connected with a power supply, the auxiliary load module is connected with the third contact, and the power module is connected with the fourth contact. When the starting circuit is in a starting mode, the first contact is communicated with the third contact, and the second contact is communicated with the fourth contact, so that the power supply supplies power to the auxiliary load module and the power module. Through the design, when the starting circuit is adjusted to the starting mode, the automobile auxiliary load is still kept to be conducted with the low-voltage power supply, so that the problem that the automobile auxiliary load is disconnected in the starting process is avoided, and the experience feeling of a user is improved.

    本发明公开了一种用于电动汽车的启动电路、电动汽车及其启动方法。该用于电动汽车的启动电路包括开关器件、辅助负载模块以及动力模块。其中,开关器件包括第一触点、第二触点、第三触点以及第四触点。第一触点和第二触点供电源连接,辅助负载模块与所述第三触点连接,且动力模块与所述第四触点连接。当启动电路处于启动模式时,第一触点与第三触点连通,且第二触点与第四触点连通,以使电源为辅助负载模块和动力模块供电。通过以上的设计,当启动电路在被调至启动模式时,汽车辅助负载仍然保持与低压电源导通,从而避免了启动过程中汽车辅助负载断开的问题,提高了用户的体验感。
