The invention relates to a high-low voltage switching control charging method, device, system and equipment, which are applied to the technical field of vehicle charging, and the method comprises the following steps: after a connection with a to-be-charged target vehicle is established, determining an output voltage at a current moment and a charging current demand value of the target vehicle, and according to the charging current demand value, determining a charging current of the target vehicle; a target power module used for supplying power to the target vehicle is determined, and the charging pile comprises a plurality of power modules connected in parallel; comparing the output voltage with a preset switching voltage to obtain a comparison result, and determining whether to execute switching from low voltage to high voltage on the target power supply module according to the comparison result; and under the condition of determining to execute the switching from the low voltage to the high voltage on the target power supply module, sequentially controlling each target power supply module to perform the switching from the low voltage to the high voltage according to a preset switching sequence of the power supply modules until all the target power supply modules complete the switching from the low voltage to the high voltage. By adopting the method, the charging rate of the vehicle can be improved.

    本申请涉及一种高低压切换控制充电方法、装置、系统及设备,应用于车辆充电的技术领域,方法包括:当与待充电的目标车辆建立连接后,确定当前时刻的输出电压和目标车辆的充电电流需求值,根据充电电流需求值,确定用于为目标车辆供电的目标电源模块,其中,充电桩包括若干并联连接的电源模块;将输出电压与预设的切换电压进行比对,得到比对结果,根据比对结果,确定是否对目标电源模块执行从低压到高压的切换;在确定对目标电源模块执行从低压到高压的切换的情况下,按照预设的电源模块的切换顺序,顺次控制各目标电源模块进行从低压到高压的切换,直至所有目标电源模块均完成从低压到高压的切换。采用本方法有助于提升车辆的充电速率。
