The invention belongs to the technical field of charging of new energy vehicles, and particularly relates to a boost charging double-loop control method, system and equipment of a vehicle. The boost charging double-loop control method for the vehicle comprises the steps that target charging voltage and target charging current requested by the vehicle are obtained, and actual charging voltage of a vehicle battery and actual three-phase current of a vehicle motor winding are collected; performing closed-loop control on the target charging voltage and the actual charging voltage to generate a first target control current based on a voltage outer-loop control strategy; according to the first target control current and the target charging current, calculating to obtain a second target control current based on a current inner loop control strategy; distributing the second target control current as a target three-phase current based on the position of the vehicle motor rotor; a duty ratio is generated according to the actual three-phase current and the target three-phase current, and a boost charging loop of the vehicle is controlled to work.

本发明属于新能源汽车的充电技术领域，具体涉及一种车辆的升压充电双环控制方法、系统、以及设备。所述车辆的升压充电双环控制方法包括：获取车辆请求的目标充电电压和目标充电电流，并采集车辆电池的实际充电电压，以及车辆电机绕组的实际三相电流；对目标充电电压和实际充电电压进行闭环控制，生成基于电压外环控制策略的第一目标控制电流；根据第一目标控制电流和目标充电电流，计算得到基于电流内环控制策略的第二目标控制电流；基于车辆电机转子的位置将第二目标控制电流分配为目标三相电流；依据实际三相电流和目标三相电流生成占空比，控制车辆的升压充电回路工作。
