The invention discloses a diagnosis control method for pulse heating of a power battery, which is characterized in that IGBT junction temperature, motor temperature and bus voltage are monitored in real time through a diagnosis module, and when an abnormal condition occurs, a control module performs power limiting processing on pulse heating, so that the loss of electric quantity on a switch can be reduced, the current can be prevented from rising too fast, and the service life of the switch is prolonged. Therefore, the safety and the reliability of pulse heating are improved.

    本发明公开了一种动力电池脉冲加热的诊断控制方法,其通过诊断模块实时对IGBT结温、电机温度和母线电压进行监测,当出现异常情况时,控制模块对脉冲加热进行限功率处理,可减少电量在开关上的损耗,可防止电流上升过快,从而提高脉冲加热的安全性和可靠性。
