Claim 12:
13. The power supply system in a high-speed maglev train according to claim 11, further comprising a second voltage converter which outputs a voltage lower than a voltage of the first voltage converter, a second voltage power grid which has a voltage lower than a voltage of the first power supply grid, and a vehicle-mounted control system; wherein
an input end of the second voltage converter is connected with the power supply grid, and an output end of the second voltage converter is connected with the second voltage power supply grid, to reduce the vehicle-mounted power supply voltage of the first power supply grid to the voltage of the second power supply grid;
the vehicle-mounted control system is connected with the second voltage power supply grid and is provided with power by the second voltage power supply grid; and
the vehicle-mounted control system is further connected with the battery management system of the power supply battery, to control operating states of the battery management system.
