Abstract: An energy and supply system includes a switching device, a battery detection device, a speed detection device, a processing device, a main storage battery and a backup storage battery. Using the speed detection device, the processing device determines whether the driving speed of the vehicle exceeds a preset speed threshold, or it determines whether the rotation speed of the engine exceeds a preset rotation speed. The processing device uses the battery detection device to determine whether the main battery capacity is greater than the preset capacity. If the processing device determines that the driving speed of the vehicle exceeds a preset speed threshold, or it determines that the rotation speed of the engine exceeds a preset rotation speed, and it determines that the main battery capacity is greater than the preset capacity, the processing device controls the switching device.
