The invention provides a high-voltage power-on method and device for a BMS parallel high-voltage architecture and a storage medium, and the method comprises the steps: carrying out the diagnosis control of a BMS based on a preset time axis according to a high-voltage power-on request sent by a VCU; performing high-voltage power-on initialization diagnosis at a first time point; performing high-voltage contactor coil diagnosis at a second time point; performing sequential opening and closing control on the plurality of high-voltage contactors at a plurality of third time points; performing adhesion diagnosis corresponding to sequential opening and closing control of the plurality of high-voltage contactors at a plurality of fourth time points; performing pre-charging at a fifth time point to complete diagnosis; if a fault is diagnosed at the first time point, the second time point, the plurality of fourth time points or the fifth time point, the BMS stops diagnosis control based on the preset time axis and reports the fault; and if no fault is diagnosed, the BMS completes high-voltage power-on based on a preset time axis and notifies the VCU. According to the invention, the safety and stability of high-voltage power-on and the traceability of troubleshooting can be improved.

    本发明提供了一种BMS并联高压架构的高压上电方法、装置和存储介质,该高压上电方法包括:根据VCU发送的高压上电请求,BMS基于预设时间轴进行诊断控制;在第一时间点进行高压上电初始化诊断;在第二时间点进行高压接触器线圈诊断;在多个第三时间点进行多个高压接触器的顺序开闭控制;在多个第四时间点进行与多个高压接触器的顺序开闭控制对应的粘连诊断;在第五时间点进行预充完成诊断;若在第一时间点、第二时间点、多个第四时间点或者第五时间点诊断出故障,则BMS停止基于预设时间轴的诊断控制,并报故障;若都未诊断出故障,则BMS基于预设时间轴完成高压上电并通知VCU。本发明可提高高压上电的安全性、稳定性,以及故障排查可追溯性。
