The invention provides a dual-power-supply switching system and method for a vehicle. The system comprises a plurality of battery packs; the first switch module is connected with the plurality of battery packs, and the first switch module is used for controlling the plurality of battery packs to be connected in series so as to output a first voltage value; the second switch module is connected with the plurality of battery packs, and the second switch module is used for controlling the plurality of battery packs to be connected in parallel so as to output a second voltage value; and the main control module is respectively connected with the first switch module and the second switch module, and the main control module is used for controlling the on-off of the first switch module and the second switch module. Through switching of the first switch module and the second switch module by the main control module, series-parallel connection of the plurality of battery packs is realized, so that free voltage switching of the first voltage value or the second voltage value output by the battery packs is realized, and the requirements of different vehicle-mounted voltages are met.

    本公开提供了一种车用双电源切换系统及方法。该系统包括若干电池包;第一开关模块,所述第一开关模块与所述若干电池包连接,所述第一开关模块用于控制所述若干电池包串联连接,以输出第一电压值;第二开关模块,所述第二开关模块与所述若干电池包连接,所述第二开关模块用于控制所述若干电池包并联连接,以输出第二电压值;主控模块,所述主控模块分别与所述第一开关模块和第二开关模块连接,所述主控模块用于控制所述第一开关模块和第二开关模块的通断。通过主控模块对第一开关模块和第二开关模块的切换,实现若干电池包的串并联,从而实现电池包输出第一电压值或第二电压值的电压自由切换,满足车载不同电压的需求。
