The invention discloses a pre-charging control method and device, a storage medium, a processor and an electronic device. The method comprises the steps that a pre-charging target voltage interval of a pre-charging capacitor is determined, the maximum value of the voltage interval is a first target voltage, and the minimum value of the voltage interval is a second target voltage; in response to the fact that the energy storage information of the low-voltage battery meets a first preset condition, controlling the DC/DC converter to pre-charge the pre-charge capacitor to a first target voltage; under the condition that the voltage of the pre-charging capacitor reaches the first target voltage, whether the electric vehicle meets a high-voltage power-on condition or not is judged; if not, whether the high-voltage side voltage of the current DC/DC converter is smaller than a second target voltage or not is judged; and under the condition that the high-voltage side voltage of the current DC/DC converter is smaller than the second target voltage, controlling the DC/DC converter to continuously pre-charge the pre-charge capacitor to the first target voltage. The technical problems that due to the fact that pre-charging components are additionally arranged, the light weight of the electric automobile is affected, and fault factors of high-voltage power-on are improved are solved.

    本发明公开了一种预充电的控制方法、装置、存储介质、处理器及电子装置。该方法包括:确定预充电容的预充目标电压区间,该电压区间的最大值为第一目标电压,该电压区间的最小值为第二目标电压;响应于低压电池的储能信息满足第一预设条件,控制DC/DC变换器为预充电容进行预充电至第一目标电压;在预充电容的电压达到第一目标电压的情况下,判断电动汽车是否满足高压上电条件;如果否,判断当前DC/DC变换器的高压侧电压是否小于第二目标电压;在当前DC/DC变换器的高压侧电压小于第二目标电压的情况下,控制DC/DC变换器为预充电容继续预充电至第一目标电压。本发明解决了由于增加预充元器件影响电动汽车的轻量化以及提高高压上电的故障因素的技术问题。
