Abstract

The invention provides a vehicle-mounted high-voltage integrated power supply system, a fuel cell vehicle and a pure electric platform. A fuel cell stack, a direct current inverter and a power storagebattery are highly integrated, mechanical, electrical and thermal management of a core high-voltage component are fully optimized, tedious cable and pipeline connections are avoided, a whole vehiclespace is efficiently utilized, and the integration level of a whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, and more specifically relates to a vehicle-mounted high-voltage integrated power supply system, a fuel cell vehicle and a pure electric platform. Background technique [0002] Fuel cell technology has been developed for decades. China started the research and development of fuel cell vehicles at the end of the last century, while internationally, Toyota, General Motors, and Mercedes-Benz are all starting mass production of fuel cell vehicles. [0003] In Toyota's latest generation Mirai fuel cell car, the fuel cell stack and the DC inverter have been integrated and connected by copper bars, and the connection process is reliable. However, since the power battery is arranged in the trunk, the power battery and the DC inverter are connected by a high-voltage line. However, due to the lack of high integration between the power battery and the DC inverter, the length of the high-voltage l...
