Integrated BMS system for fuel battery automobile

Abstract

The invention relates to an integrated BMS system for a fuel battery automobile. The integrated BMS system for the fuel battery automobile comprises a control board and an input port; an integration system is electrically connected to the control board; the integration system is electrically connected with a power board through a lead; an input port is electrically connected with an input end of the control board; a network connection port is connected to the control board through a CAN bus; and a cooling fan, a water pump, a PTC heater and a fan relay are connected to the power board through leads in sequence. According to a four-in-one control system integrated with a power battery BMS, a vehicle control unit VCU, a double-way DCDC and a heat management system, by using a highly integrated power domain controller, a harness circuit is effectively reduced, the lightweight contribution rate of a harness is high, ECU parts of the whole vehicle are also reduced, the production, design and management cost of a power system is reduced, the double-way DCDC possesses expansibility, a high voltage auxiliary power supply can be conveniently integrated, and the integrated BMS system for the fuel battery automobile is very suitable for hydrogen fuel battery automobiles.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicle integrated systems, in particular to an integrated BMS system for fuel cell vehicles. Background technique [0002] With the development of fuel cell vehicles and the wide application of network technology in automobiles, as the requirements of automobiles for lightweight, the electrical architecture continues to evolve and develop, and a high degree of integration will inevitably become a trend. This invention is aimed at the concept of domain controllers A power domain controller for fuel cell vehicles with highly integrated functions is designed. [0003] Generally, the power battery BMS, vehicle controller VCU, bidirectional DCDC, and thermal management system are four independent components, and each has its own CPU and its control circuit, which increases the complexity of the entire operating system and is inconvenient for users to perform control operations. . Contents of the ...
