Abstract

The invention discloses a charging pile multiple insulation detection control method and system, and the method comprises the steps: physically connecting a charging pile and a charging vehicle, and starting charging; obtaining the maximum allowable charging voltage of a battery management system (BMS); starting a charging module according to the maximum allowable charging voltage of the BMS; judging whether the charging module is normally started or not: if so, normally carrying out insulation detection and continuing the charging process; if not, further judging whether the insulation detection frequency reaches a preset value or not: if so, stopping the charging process according to a starting failure result; if the preset value is not reached, returning to the step of starting the charging module according to the maximum allowable charging voltage of the BMS. According to the invention, the problem that the insulation detection of the DC charging pile is affected by the failure rate of the module is solved, safe and reliable charging of the electric automobile is realized, and the development of the electric automobile industry is promoted.

一种充电桩多次绝缘检测控制方法及系统，该方法包括物理连接充电桩和充电车辆，启动充电；获取电池管理系统BMS最高允许充电电压；根据所述BMS最高允许充电电压启动充电模块；判断充电模块是否正常启动：如果是，则正常进行绝缘检测并继续充电流程；如果否，则进一步判断绝缘检测次数是否达到预设值：如果达到预设值，则以启动失败的结果停止充电流程；如果未达到预设值，则回到根据所述BMS最高允许充电电压启动充电模块的步骤。本发明解决了直流充电桩绝缘检测时受到模块故障率影响的问题，实现了电动汽车的安全、可靠充电，对电动汽车行业的发展起到推动作用。
