The invention provides a pre-charging device, a control method and device thereof, a storage medium and a processor. The pre-charging device comprises a high-voltage input end and a main relay, wherein the main relay is electrically connected with the high-voltage input end and a pre-charging capacitor. The pre-charging device further comprises a preparation pre-charging circuit, a detection module and a control module, wherein the preparation pre-charging circuit is connected with the main relay in parallel, the preparation pre-charging circuit comprises at least one branch circuit connectedin parallel, and any branch circuit comprises at least one pre-charging relay and at least one pre-charging resistor; the detection module is electrically connected with the pre-charging capacitor; and the control module is in communication connection with the detection module, and is electrically connected with the plurality of pre-charging relays and the main relay and used for controlling the on-off of the plurality of pre-charging relays according to the capacitance. According to the pre-charging device, the main relay and all the pre-charging relays are disconnected under the condition that the capacitance of the pre-charging capacitor is greater than or equal to the preset capacitance, so that the high-voltage input end cannot pre-charge the pre-charging capacitor, and the potentialsafety hazard in the pre-charging process is eliminated.
本申请提供了一种预充电装置、其控制方法和装置、存储介质和处理器,该预充电装置包括高压输入端和主继电器,主继电器与高压输入端和预充电容分别电连接,预充电装置还包括:预备预充电路,与主继电器并联,预备预充电路包括至少一个并联的支路,任意一个支路包括至少一个预充继电器和至少一个预充电阻;检测模块,与预充电容电连接;控制模块,与检测模块通信连接,且与多个预充继电器以及主继电器分别电连接,用于根据电容量控制多个预充继电器的通断。上述预充电装置在预充电容的电容量大于或者等于预定电容量的情况下,断开主继电器和所有预充继电器,使得高压输入端无法对预充电容进行预充电,从而消除了预充电过程的安全隐患。
