基于SAEJ1939协议的车用燃料电池管理系统设计

Design of vehicle fuel cells management system based on SAE J1939 agreement

采用汽车级单片机MC912XEP100作为主控芯片,依据SAE J1939通讯协议标准,完成了车用燃料电池管理系统的单膜电压检测单元和电堆主控单元硬件电路设计和软件程序设计,开发了基于SAE J1939的多路CAN总线通讯程序,并通过样机验证了设计。

Using MC912 XEP100 automotive MCU as main controller, according to the SAE J1939 agreement standards, The hardware circuits design and software programs design is completed, which refer to the voltage measurement circuit and main control circuit in vehicle fuel cells management system. The multiple CAN bus communication programs are developed, and at last the design is verified by the prototype.
