Abstract

The invention relates to a vehicular fuel cell energy distribution management control device. The vehicular fuel cell energy distribution management control device comprises a processor, a power source module, a vehicular bus communication module, a current collector, a voltage collector and a driver; the power source module is connected with the processor; the vehicular bus communication module is connected with the processor and used for data receiving and sending; the output end of the current collector is connected with the processor, and the input end of the current collector is connectedwith a dynamic bus for collecting the current of the dynamic bus; the output end of the voltage collector is connected with the processor, and the input end of the voltage collector is connected withthe dynamic bus for collecting the voltage of the dynamic bus; and one end of the driver is connected with the processor, and the other end of the driver is connected with contactors and relays in anenergy distribution system. Compared with the prior art, a bus is in communication with a fuel cell engine controller FCU so that the functions such as power-on and power-off, load voltage and current monitoring and failure detection and reporting of electrical appliances can be achieved.

Description

technical field [0001] The invention relates to fuel cell control technology, in particular to a vehicle-mounted fuel cell energy distribution management control device. Background technique [0002] A fuel cell is an electrochemical reaction device that directly converts chemical energy into electrical energy. According to different electrolytes, it can be divided into proton exchange membrane fuel cells, alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells and solid oxide fuel cells. Proton exchange membrane fuel cells have low operating temperature, high current density, fast response and stable performance. Moreover, the reaction product is only water, which is non-corrosive. Therefore, proton exchange membrane fuel cells have broad market prospects in the fields of vehicle transportation and backup power. [0003] At present, most of the energy distribution work of the on-board fuel cell system is integrated in the fuel cell engine controller ...
