Power supply method and power supply system of vehicle, electronic apparatus, control system, and vehicle

A power supply method of a vehicle, wherein the power supply method of the vehicle is applied to a power supply system of the vehicle, the system comprises a first load, a second load, a first battery pack, a second battery pack, and a bidirectional voltage converter;

• the first load is connected to the first battery pack;
• the second load is connected to the second battery pack;
• the bidirectional voltage converter is connected to both the first battery pack and the second battery pack;
• and the method comprises:
• controlling energy transmission between the first battery pack and the second battery pack based on a first state of charge of the first battery pack and a second state of charge of the second battery pack by the bidirectional voltage converter, wherein the first battery pack is configured to supply power to the first load, and the second battery pack is configured to supply power to the second load.
