Electric appliance framework of hydrogen fuel cargo compartment type medical vehicle

Abstract

The invention discloses an electric appliance framework of a hydrogen fuel cargo compartment type medical vehicle. The framework comprises a VCU, a hydrogen system assembly, a high-voltage battery pack, an accessory controller and an inverter. The VCU is connected with the high-voltage battery pack, the hydrogen system assembly, the accessory controller and the inverter through a CAN bus, and the high-voltage battery pack is electrically connected with the hydrogen system assembly, the accessory controller and the inverter through high voltage. The high-voltage battery pack is used for outputting or inputting corresponding power according to the relation between the output power of the hydrogen system assembly and the equipment demand power; and the inverter is used for converting direct current output by the high-voltage battery pack or the hydrogen system assembly into 220V alternating current. According to the technical scheme, when the hydrogen fuel medical vehicle goes out, the power utilization requirement of medical equipment in the medical vehicle can be met without an additional generator or an external 220V mains supply.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electrical architecture of a hydrogen-fueled van-type medical vehicle. Background technique [0002] Along with economic development, the problems of energy shortage and environmental pollution have become increasingly prominent. my country has begun to attach importance to the research and development of hydrogen fuel cell vehicles, and its technological development has been promoted to the level of national strategic planning. The national "Three-Year Action Plan for Winning the Blue Sky Defense War" clearly It is pointed out that it is required to accelerate the elimination of old vehicles and the switching of new energy vehicles. Since hydrogen energy has a series of advantages such as abundant resources, clean environmental protection and recyclable utilization, it is also regarded as an important part of the future energy system, and hydrogen fuel vehicles hav...

Problems solved by technology

[0003]At present, there is no cargo-type medical vehicle in China. The traditional bus-type medical vehicle still uses a fuel engine structure. 220V mains electricity; while traditional bus-type medical vehicles have built-in engines and low-power generators, which work on the same principle as ordinary generators, resulting in resource overlap and waste, and gasoline generators emit large pollution; when the vehicle is not equipped with a generator, connect 220V The mains power is extremely inconvenient, and the normal use of the equipment cannot be guaranteed
