The invention discloses a high-voltage input undervoltage fault detection method and device for an electric vehicle and a computer storage medium, and the method comprises the steps: obtaining the internal voltage of a target part after a battery pack of the electric vehicle is detected to be electrified and before the target part is not electrified; judging whether the internal voltage is smaller than or equal to a preset voltage value; and if yes, determining that the target component has a high-voltage input under-voltage fault. Thus, after the battery pack of the electric vehicle completes high-voltage power on and before the target component does not complete high-voltage power on, whether the target component has the high-voltage input undervoltage fault or not can be accurately detected, and the problem that in the prior art, the high-voltage input undervoltage fault can only be detected when the target component is in the working state is solved; the convenience of management and maintenance of the electric vehicle is improved, and the user experience is improved.

    本申请公开了一种电动汽车的高压输入欠压故障检测方法、装置及计算机存储介质,包括:在检测到电动汽车的电池包完成上高压电后且目标部件未完成上高压电前,获取所述目标部件的内部电压;判断所述内部电压是否小于或等于预设电压值;若是,则确定所述目标部件存在高压输入欠压故障。如此,在电动汽车的电池包完成上高压电后且目标部件未完成上高压电前,能够准确检测出所述目标部件是否存在高压输入欠压故障,解决了现有技术中只有在目标部件处于工作状态下才能检测高压输入欠压故障的问题,提高了对电动汽车管理和维护的便利性,提升了用户体验。
