一种氢燃料电池上下电装置及其操作方法
技术领域
本发明涉及一种氢燃料电池，尤其涉及一种氢燃料电池上下电装置及其操作方法，属于新能源汽车技术领域。
背景技术
新能源汽车对于解决环境污染、能源危机具有重大的意义，引起了越来越多人的关注。而氢燃料电池汽车因其无污染、零排放成为电动汽车研究的一个热点，它克服了纯电动汽车续驶里程短的缺陷。同时氢燃料电池汽车具有能量转化效率高、环境友好等内燃机汽车不可比拟的优点，而且仍然保持传统内燃机汽车的加速性能、高速度、长距离行驶和安全、舒适等性能。
目前，氢燃料电池汽车技术还处于研究、开发和示范运行阶段，在车辆系统技术、加氢设施、车辆储氢、制造成本、运行经验、标准和法规等方面，还有大量问题需要系统地考虑和解决，这就需要政府、企业、研究机构和各国政府之间的紧密合作。因此，开展氢燃料电池汽车技术方案研究和测试技术研究已显得十分必要。
发明内容
本发明要解决的技术问题是：提供一种氢燃料电池上下电装置及其操作方法，本发明基于CAN通讯设计了氢燃料电池系统上下电策略流程时序与逻辑控制各节点响应。本发明中所提及上下电策略流程控制结合了氢燃料汽车动力系统结构的特点，具有实用性与先进性，该策略在实际中可高效执行，可为新的氢燃料汽车开发提供一种新的途径。
本发明的技术方案为：一种氢燃料电池上下电装置，它包括氢燃料电池、KL15和整车24V电源，所述整车24V电源的负极与氢燃料电池的24V电源负极连接，整车24V电源的正极通过低压继电器与氢燃料电池的24V电源正极连接，所述低压继电器包括有F1-F5，其中：F1与氢燃料电池的24V电源正极连接，F2与氢排加热供电正极连接，F3与散热风扇供电正极连接，F4与辅助水泵供电正极连接，F5与HMS供电正极连接。
一种氢燃料电池上下电装置的操作方法，所述方法为：氢燃料电池系统不工作时会处于休眠状态，唤醒时，需要给KL15上电，启动KL15信号，表示发动机点火信号，也表示车钥匙启动，启动汽车的信号，随后氢燃料电池会进入自检状态，如自检无问题，氢燃料电池会处于待命状态，一旦收到开机指令，氢燃料电池就会处于开机状态，开机完成后，氢燃料电池正常运行工作，如果想停止其工作，只需要给氢燃料电池发关机指令，氢燃料电池就会处于关机状态，此时正常关机完成，氢燃料电池又处于待命状态，这时将KL15信号断电，30s后，氢燃料电池又恢复至初始休眠状态；
如自检无问题，氢燃料电池会处于待命状态，一旦收到开机指令，氢燃料电池就会处于开机状态，如此时开机未完成，失败，氢燃料电池就会处于关机状态，或者此时处于故障关机/紧急关机状态时，氢燃料电池会呈现出错误状态，无法正常运行使用，这时再将KL15信号断电，30s后，氢燃料电池又恢复至初始休眠状态。
本发明的有益效果是：与现有技术相比，采用本发明的技术方案，本发明基于CAN通讯设计了氢燃料电池系统上下电策略流程时序与逻辑控制各节点响应。本发明中所提及上下电策略流程控制结合了氢燃料汽车动力系统结构的特点，具有实用性与先进性，该策略在实际中可高效执行，可为新的氢燃料汽车开发提供一种新的途径，取得了很好的使用效果。
