Abstract

The invention provides an integrated IPU system for a hydrogen fuel cell automobile. The integrated IPU system comprises a control board, an integrated circuit and a power board. The control panel comprises a motor controller MCU, a high-voltage distribution box PDU, a vehicle-mounted buck converter DCL, and a fuel cell boosting converter FCBC. The control panel is electrically connected with theintegrated circuit through a wire, the power panel is connected with the integrated circuit through a wire, an IGBT power element is integrated on the power panel, and the IGBT power element is connected to a driving motor, a PTC, a compressor and a storage battery through five sets of wire output. A four-in-one control system of the motor controller MCU, the fuel cell boosting converter FCBC, thehigh-voltage distribution box PDU and the vehicle-mounted buck converter DCL is integrated. The highly integrated power domain controller effectively reduces wire harness loops, has a very high contribution rate to light weight of wire harnesses, reduces ECU parts of the whole vehicle, reduces the production design management cost of a power system, and is very suitable for hydrogen fuel cell vehicles.

Description

technical field [0001] The invention relates to the field of hydrogen energy vehicles, in particular to an integrated IPU system for hydrogen fuel cell vehicles. Background technique [0002] With the development of fuel cell vehicles and the wide application of network technology in vehicles, with the requirements of lightweight vehicles, the electrical architecture continues to evolve and develop, and a high degree of integration will inevitably become a trend. The existing fuel cell vehicle control system, The degree of integration is not enough, the functions are not complete, the wiring harness circuit is intricate, the degree of light weight is relatively low, the ECU parts of the whole vehicle are more and more complicated, and the production design management cost of the power system is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an integrated IPU system for hydrogen fuel cell vehicle...
