Description
technical field [0001] The invention relates to the field of batteries, in particular to a power supply device and a power supply method. Background technique [0002] Existing electric vehicles (Electrical Vehicle, referred to as EV) are equipped with two power supplies: one power supply (namely the main power supply) is used to supply power to the main electric system of the electric vehicle, and the main electric system does not include the motor driving the electric vehicle; Another power supply, the backup power supply, is used to supply power to the auxiliary electric system. The backup power supply is usually a lead-acid battery. figure 1 Shown is a schematic diagram of a conventional solution 100 for providing backup electric energy to electric vehicles in the prior art. The lead-acid battery 102 is coupled with the output terminal of the DC / DC converter 104, and serves as a backup power supply to supply power to the electric device 106 of the electric vehicle. Th...
