The invention provides a vehicle charging control method, device and equipment and a computer readable storage medium, and the method comprises the steps that when the temperature is low and the rechargeable power of a battery is zero, the battery powers on a high-voltage part of a vehicle, and the high-voltage part comprises a thermal manager and a DCDC; then switching an external power supply to power on the high-voltage component; a heat manager is started to heat the battery, and meanwhile, a DCDC is started to work; when the temperature of the battery reaches the preset temperature, the heat manager stops heating, and the DCDC is kept to work continuously; and controlling an external power supply to start charging the battery. Before the external power supply is connected, the vehicle battery is used for supplying high voltage to the high-voltage component, when the external voltage is connected, the high-voltage component is in a normal voltage state, a boosting process is not needed, and the pre-charging time is saved. In the process, the DCDC is kept working continuously, so that when the high-voltage component stops working, the DCDC can consume overvoltage caused by recoil of the external power supply due to the fact that the high-voltage component stops working.
本申请提供一种车辆充电控制方法、装置、设备和计算机可读存储介质,该方法包括:当低温度且电池可充电功率为0时,由电池为车辆的高压部件上电,高压部件包括热管理器和DCDC;然后切换外部电源为高压部件上电;启动热管理器为电池加热,同时启动DCDC工作;当电池温度达到预设温度时,热管理器停止加热,并保持DCDC继续工作;控制外部电源开始为电池充电。本申请在联通外部电源前,使用车辆电池为高压部件上高压,当接通外部电压时,高压部件已经处于正常电压状态,不需要升压过程,节省了预充时间。在上述过程中保持DCDC持续工作,使停止高压部件工作时DCDC能消耗停止高压部件工作所导致的外接电源反冲出现的过压。
