The invention provides a sodium ion battery power supply circuit and method and an automobile. The sodium ion battery power supply circuit comprises a power supply controller, a first switch unit and a voltage conversion unit, the power supply controller is respectively connected with the sodium ion battery and the first switch unit, the first switch unit is respectively connected with the sodium ion battery and the voltage conversion unit, and the voltage conversion unit is further connected with a high-voltage distributor of a vehicle. When the battery voltage output by the lithium ion battery is smaller than the minimum working voltage of the high-voltage distributor, the connection between the lithium ion battery and the voltage conversion unit is conducted, and the voltage conversion unit is used for boosting the battery voltage to supply power to the high-voltage distributor; therefore, the energy remaining in the lithium ion battery can be effectively utilized.

    本发明提供了一种钠离子电池供电电路、方法及汽车,该钠离子供电电路包括:供电控制器、第一开关单元和电压转换单元;所述供电控制器分别与钠离子电池以及所述第一开关单元连接,第一开关单元分别与所述钠离子电池以及所述电压转换单元连接,所述电压转换单元还与车辆的高压配电器连接。本发明在锂离子电池输出的电池电压小于高压配电器的最小工作电压时,通过导通锂离子电池与电压转换单元之间的连接,利用电压转换单元对电池电压进行升压,为高压配电器进行供电,从而有效的对锂离子电池内的存留能量进行利用。
