The invention discloses a method, a device, equipment and a medium for ensuring the voltage endurance capability of a power chip, and determines whether to control the chip in a power module to carry out direct-current conduction heating according to the temperature of a thermistor in the power module after a vehicle is started and before a motor controller is started, thereby realizing the purpose of ensuring the voltage endurance capability of the power chip by utilizing the characteristic that the chip can emit heat. The chip is actively heated under the low-temperature condition, so that the risk that the whole vehicle loses power due to the fact that the chip is broken down when the vehicle is quickly started under the full-load condition due to the fact that the voltage resistance of the motor controller power chip is reduced under the low-temperature environment is effectively avoided, and the running safety of the vehicle is effectively improved.
公开了一种保证功率芯片耐压能力的方法、装置、设备及介质,通过在车辆启动后电机控制器未启动前,根据功率模块内部热敏电阻的温度,确定是否控制所述功率模块中的芯片进行直流导通加热,实现了利用了芯片本身能够发热的特性,在低温条件下主动给芯片自身加热,有效地避免了由于电机控制器功率芯片在低温环境下耐电压能力下降导致的车辆在满负荷条件下快速启动时出现的芯片被击穿,进而导致整车失去动力的风险,有效的提高了车辆的运行安全。
