The invention provides a battery pack power supply compensation control method and system, and the method comprises the steps: analyzing the motor output data of a DC motor, judging whether the DC motor is in a full-load working state or not, determining the output power gap information of the DC motor driving an electric vehicle to a target driving state, and combining the power conversion efficiency of the DC motor. Electric quantity information required by the direct-current motor to drive the electric vehicle to a target driving state is determined, and a reliable basis is provided for switching the battery pack to a compensation working mode; and after the battery pack is switched to the compensation working mode, adjusting charging parameters of the generator for charging the battery pack based on the electric energy storage characteristic information of the battery pack, so that the battery pack reaches a target working state, and considering the electric energy transmission state of the battery pack to the motor and the electric quantity consumption state of the battery pack at the same time. And power supply compensation is performed on the battery pack, so that efficient charging of the battery pack and effective utilization of electric energy in the battery pack are realized.

    本发明提供电池包供电补偿控制方法和系统,分析直流电动机的动机输出数据,判断直流电动机是否处于满载工作状态,以此确定直流电动机驱动电动车至目标行驶状态的输出动力缺口信息,并结合直流电动机的动力转换效率,确定直流电动机驱动电动车至目标行驶状态所需电量信息,为电池包是否切换至补偿工作模式提供可靠依据;当电池包切换至补偿工作模式后,基于电池包的电能存储特征信息,调整发电机对电池包进行充电的充电参数,使电池包达到目标工作状态,其同时考虑电池包对电动机的电能输送状态和电池包自身的电量消耗状态,对电池包进行供电补偿,实现对电池包高效充电和电池包内部电能的有效利用。
