In certain embodiments, the control system further comprises: and the energy supply unit 30, wherein the energy supply unit 30 is connected with the central controller 10 and is used for supplying electric energy to the central controller 10. Preferably, the control system further includes a transformer 40, and the transformer 40 is disposed between the energy supply unit 30 and the central controller 10, and is used for transforming the voltage output by the energy supply unit 30 and outputting the transformed voltage to the central controller 10. The energy supply unit 30 is preferably a power battery, and the voltage provided by the power battery is transformed by the transformer 40 to meet the power consumption requirement of each low-voltage electric device, and then the central controller 10 supplies power to each low-voltage electric device by outputting different voltages. Because the low-voltage electric equipment is not directly connected with the power supply battery any more, the power utilization environment of the electric equipment can be better protected, and the endurance mileage of the electric vehicle is increased.
In certain embodiments, the control system further comprises: the energy storage unit 50 is connected with the central controller and used for storing the additional electric energy provided by the energy supply unit; the extra electric energy is the electric energy left after the electric energy provided for the central controller is deducted from the total electric energy provided by the energy supply unit.

In an actual application scenario, the first low-voltage electric device 201 may be a device such as a lamp, and the second low-voltage electric device 202 may be a controller. When the output voltage of the central controller is b (V), all the controllers are informed to enter a low power consumption mode. When the controller detects the voltage change, the controller enters a low power consumption mode; for the controller which is appointed to stop working, the controller stops working and can be awakened; and maintaining the rated power consumption mode for the first low-voltage electric equipment such as a lamp.

(1) powering off the vehicle within 0-10 minutes (mode 1):
the central controller normally supplies power to all voltage electrical appliances according to a rated power consumption mode;
(2) powering off the vehicle within 10-30 minutes (mode 2):
the central controller supplies power to a part of the controllers (such as entertainment systems, wireless charging modules, and the like, and necessary working controllers such as T-Box, PEPS, and the like) in a rated power consumption mode.
(3) After 30 minutes of discharge (mode 3):
the central controller supplies power to a few controllers (such as necessary working controllers of T-Box, PEPS and the like) in a low-power mode, and energy consumption is saved to the maximum extent.
In other embodiments, when the central controller detects that the energy of the storage battery is insufficient, the power battery is awakened through a specific line, the power battery supplies power to the central controller, and the central controller further supplements the power for the storage battery. During the power supplement of the storage battery, the working mode of the central controller is unchanged, and the power supply states of other controllers are also unchanged by the central controller.
When the vehicle is unlocked by any means, the central controller automatically enters the mode 1 to ensure that the vehicle can be normally used for the first time. When the user remotely controls the vehicle, the central controller changes the power supply of the corresponding line to ensure normal control.
