Kind Code:
A1
Abstract:
A power source switching system, a power supply circuit switching method for the power source switching system, and an electric vehicle comprising the power source switching system. The power source switching system comprises: a first power source unit (02), a second power source unit (03) and a system switching control unit (01), wherein the system switching control unit (01) is electrically connected to the first power source unit (02) and the second power source unit (03), and the system switching control unit (01) controls the first power source unit (02) and the second power source unit (03) to be in series connection or parallel connection, and controls the switching between the series connection of the first power source unit (02) and the second power source unit (03) and the parallel connection of the first power source unit (02) and the second power source unit (03), thereby realizing charging and discharging processes of the first power source unit (02) and the second power source unit (03). By means of the technical solution, a working mode of a power source unit can be freely switched according to the power output of an electric vehicle, thereby improving the user experience.
