The invention discloses an insulation abnormity early warning system for a new energy lithium battery vehicle. The insulation abnormity early warning system comprises a monitoring module, an early warning module, a data management and control platform and a data analysis module. According to the invention, insulation abnormity monitoring is carried out on each high-voltage component of the new energy lithium battery automobile, the response value and the response list corresponding to the insulation abnormity of each high-voltage component are measured and calculated based on the action time of the driver, and primary and secondary insulation abnormity danger early warning is carried out on the driver. The unsafe situation caused by the fact that the vehicle is not maintained in time is avoided; a safety maintenance timing unit is arranged, safety maintenance timing is carried out after the new energy lithium battery automobile sends out the first insulation abnormity early warning, and insulation abnormity judgment is carried out on other high-voltage components of the new energy lithium battery automobile on the basis. The situation of inaccurate secondary early warning time caused by insulation abnormity of other high-voltage components when the driver does not respond to the first insulation early warning is avoided, and the safety of the driver is further ensured.

    本发明公开了新能源锂电池汽车绝缘异常预警系统,包括监测模块、预警模块、数据管控平台和数据分析模块。本发明通过对新能源锂电池汽车的各个高压部件进行绝缘异常监测并基于驾驶人员的行动时间测算各个高压部件绝缘异常对应的响应值和响应列表,对驾驶人员进行一次和二次绝缘异常危险预警,避免了车辆未进行及时维修导致不安全情况发生;设置安全维修计时单元,在新能源锂电池汽车发出第一次绝缘异常预警后进行安全维修计时,在此基础上对该新能源锂电池汽车的其余高压部件进行绝缘异常判定,避免了在驾驶人员尚未对第一次绝缘预警做出反应时其余高压部件出现绝缘异常导致的二次预警时间不准确情况发生,进一步确保了驾驶人员的安全。
