摘要
电动汽车应用的燃料电池发动机,一般具有100～600V的直流电源电压。应当对其绝缘性能进行相应的试验研究及在线监测,确保符合电动汽车(EV)的电气安全要求。我们利用绝缘电阻在线监视仪在线测量燃料电池发动机中质子交换膜燃料电池(PEMFC)堆的绝缘电阻,研究各种条件下(如:燃料电池电流输出、操作温度等)燃料电池绝缘电阻的变化规律,为提高和改善电动汽车用燃料电池的绝缘性能提供参考。
Fuel cell engine for EV is typically of a voltage between 100 V DC to 600 V DC. Its insulation to the ground should be on-line monitored and studied for the demand of EV electrical safety. For improving EV fuel cell stacks insulation performance, through study the rules or the tendency of variation of fuel cell stacks insulation resistance to the ground with different conditions, such as fuel cell output current, operation temperature, the insulation resistance of PEMFC for EV engine is measured with on-line insulation resistance monitor.
