The invention discloses a vehicle-mounted battery state-of-charge calibration method and system, a medium and a terminal. The method comprises the following steps: acquiring state data of a to-be-processed vehicle-mounted battery in real time; after the controller of the vehicle enters the dormant standing state, if the current state data meet the preset standing working condition, fault detection is carried out on a voltage acquisition chip of the controller; if the detection result of the voltage acquisition chip is no fault, the battery cell standing back pressure performance of the vehicle-mounted battery is analyzed based on the state data at the previous moment when the controller enters the dormant standing state and the current state data, and if it is analyzed that the battery cell of the vehicle-mounted battery is fully stood based on the analysis result, the battery cell standing back pressure performance of the vehicle-mounted battery is recovered. If yes, the first charge state of the vehicle-mounted battery is obtained in real time, the first charge state is calibrated based on the preset minimum charge state and the average charge state, and the second charge state of the vehicle-mounted battery is obtained. According to the invention, the state of charge calibration is realized, and the influence of fluctuation generated by abnormal voltage sampling on the calibration precision can be avoided.

    本发明公开了一种车载电池荷电状态校准方法、系统、介质及终端,包括:实时获取待处理的车载电池的状态数据;在车辆的控制器进入休眠静置状态之后,若当前的状态数据符合预设的静置工况,则对控制器的电压采集芯片进行故障检测;若电压采集芯片的检测结果为无故障,则基于控制器进入休眠静置状态时的前一时刻的状态数据、以及当前的状态数据,分析车载电池的电芯静置回压性能,并基于分析结果,若分析到车载电池的电芯静置充分,则实时获取车载电池的第一荷电状态,并基于预设的最小荷电状态和平均荷电状态,对第一荷电状态进行校准,得到车载电池的第二荷电状态。采用本发明实现荷电状态校准,能够避免电压采样异常产生波动对校准精度的影响。
