[0002] Currently, fuel vehicles still dominate the global automotive market. The power system of fuel vehicles usually relies on generators to supply power to the battery, and the excess electrical energy during vehicle operation is usually not effectively utilized, resulting in a large amount of energy waste. In addition, when a fuel vehicle is idle for a long time, the battery power will gradually deplete, easily causing problems such as difficult starting and shortened battery life. Therefore, how to efficiently utilize the excess electrical energy during vehicle operation and maintain the battery power after the vehicle has been idle for a long time has become a technical problem to be solved urgently.

[0013] In the above solution, optionally, the electrical energy output port outputs electrical energy at a standard voltage of 220V, which is suitable for various electrical appliances, mobile devices, outdoor power supply devices, and emergency lighting devices.

[0014] In the above solution, optionally, the device further includes a high-voltage to low-voltage transformer module, which is connected to the high-voltage battery module. When the vehicle is idle for a long time, it converts the high-voltage electrical energy stored in the high-voltage battery module into low-voltage electrical energy to replenish the low-voltage battery module, ensuring that the vehicle can maintain a normal battery power even when idle.

[0017] In the above solution, optionally, the intelligent control chip module also has a safety protection function, which can prevent the battery from overcharging and over-discharging, and improve the service life and safety of the battery.

[0018] In the above solution, optionally, the high-voltage battery module and the low-voltage battery module are of a detachable design, and users can replace or maintain the battery module according to needs to ensure that the battery system remains in good condition for a long time.

[0019] Compared with the prior art, the present application has at least the following beneficial effects:

[0020] This application is based on further analysis and research of the problems in the prior art. It is recognized that the excess electric energy during the driving of vehicles in the prior art is usually not effectively utilized, resulting in a large amount of energy waste. By setting up a low-voltage battery module for storing the excess electric energy generated during vehicle driving; an inverter module connected to the low-voltage battery module to convert the electric energy in the low-voltage battery into high-voltage electric energy; a high-voltage battery module connected to the inverter module for storing the high-voltage electric energy converted from the low-voltage battery module; and an electric energy output port connected to the high-voltage battery module, which can output the stored high-voltage electric energy at a voltage of 220V for external devices to use. This solution stores the excess electric energy generated during vehicle driving through the low-voltage battery module, then converts the low-voltage electric energy into high-voltage electric energy through the inverter and stores it in the high-voltage battery, and finally outputs the electric energy at a standard voltage of 220V through the electric energy output port for external devices to use. This design can not only utilize the excess electric energy of the vehicle but also supply power to other electrical devices.

[0021] When the vehicle is driving normally, the excess power generation of the generator is wasted. This invention recovers the excess electricity of the vehicle, initially stores it in the low-voltage battery, and then stores the electric energy in the high-voltage battery through a low-voltage to high-voltage inverter. It is stored permanently. The high-voltage battery of this application stores electric energy. Through the high-voltage power output terminal, it can be used for normal outdoor equipment power consumption. The output voltage of the high-voltage battery is 220V, and various electrical devices can be used. When the vehicle is left idle for a long time, the low-voltage battery will naturally lose some low-voltage electric energy. The electric energy stored in the high-voltage battery of this invention can be converted from high-voltage electricity to low-voltage electricity through a high-voltage to low-voltage transformer to supplement the low-voltage battery with electric energy, so that the idle vehicle can be used normally without replenishing low-voltage electricity.
