Description

Vehicle-mounted new energy two-way energy storage power supply system

technical field

This patent relates to a vehicle-mounted new energy bidirectional energy storage power supply system. The system uses the engine of the vehicle body as the power source, and combines the new energy storage power generation system with the diesel power generation system through devices such as photovoltaic arrays, multi-mode smart inverters and battery packs, and realizes the two-way flow of energy, making the vehicle power supply system Provides stable AC and DC power.

Background technique

Traditional on-board power generation systems generally simply use diesel generators to provide stable power. With the increasingly harsh environment, the country gradually advocates the use of green new energy technology to replace traditional fuel-fired power generation technology. Completely relying on the internal combustion engine power generation system, there are disadvantages such as smoke emission, high energy consumption, and loud noise. If only new energy sources (such as photovoltaic power generation, wind power generation, etc.) are simply used, there will be harsh environments such as rainy days or no wind, and it is difficult to guarantee stable power supply.

The on-board new energy two-way energy storage power supply system is an innovative combination of the traditional on-board power generation system and the new energy power generation system. Combining photovoltaic power generation and fuel generator power generation, and adding energy storage batteries, the system can provide stable AC and DC power through multi-mode bidirectional smart inverters and DC/DC modules. In the case of sufficient sunlight, solar power can be used to provide electric energy. At the same time, the excess electric energy can be used to charge the energy storage battery. When the sunlight is insufficient, it can be output by the generator and the battery. It can provide a set of DC power supply, and the effective use of solar energy saves fuel consumption, reduces smoke and dust emissions, and at the same time reduces noise, effectively reducing environmental pollution.
