The invention provides a vehicle and a lithium ion battery starting power supply system thereof, and relates to the technical field of vehicle equipment. The lithium ion battery starting power supplysystem comprises a lithium ion battery pack, a first switch group, a starting circuit, a controller and a heating circuit, wherein when the controller detects that the working state is on and the temperature is lower than or equal to a first preset temperature, a first control instruction is sent to the first switch group so as to enable a first switch to be switched off and enable a second switchto be switched on, the lithium ion battery pack supplies power to the heating circuit, and the heating circuit heats the lithium ion battery pack; after the controller determines that the temperatureis greater than or equal to a second preset temperature, a second control instruction is sent to the first switch group so as to enable the first switch to be switched on; and a third control instruction is sent to a second switch group so as to enable a third switch and a fourth switch to be switched on, the lithium ion battery pack supplies power to a super capacitor, the super capacitor supplies power to an engine of the vehicle. The technical problem that a lithium battery cannot supply power to the engine of the vehicle under the low-temperature condition in the prior art is solved.
本发明提供了一种车辆及其锂离子电池启动电源系统,涉及车辆设备的技术领域,包括:锂离子电池组,第一开关组,启动电路,控制器和加热电路;控制器检测出工作状态为开启和温度低于或等于第一预设温度时,向第一开关组发送第一控制指令,以使第一开关断开、第二开关闭合,以使锂离子电池组为加热电路供电,以使加热电路加热锂离子电池组;控制器确定出温度大于或等于第二预设温度之后,向第一开关组发送第二控制指令,以使第一开关闭合;并向第二开关组发送第三控制指令,以使第三开关和第四开关闭合,以使锂离子电池组为超级电容供电,以使超级电容为车辆的发动机供电,解决了现有技术中锂电池在低温条件下无法为车辆的发动机供电的技术问题。
