The invention provides a high-power direct-current charger system capable of realizing quick charging and a quick charging method, and relates to the technical field of charging. The controller can count the (N + 1) th variance of the (N + 1) th residual electric quantity of the rechargeable batteries of the vehicles corresponding to the plurality of accessed high-power direct-current chargers; and determining the difference value between the Nth variance and the (N + 1) th variance as the Nth variance reduction rate, and if the difference value between the Nth variance reduction rate and the (N-1) th variance reduction rate is greater than a set rate threshold, updating network parameters configured by the power distribution network model by adopting the reinforcement learning model. And the controller controls the power distribution unit to distribute charging power to the plurality of accessed high-power direct-current chargers according to a power distribution strategy, so that the plurality of accessed high-power direct-current chargers charge rechargeable batteries of the plurality of vehicles according to the distributed charging power. The time for charging the rechargeable batteries of a plurality of vehicles at the same time can be shortened to the maximum extent.
本发明提供的一种能实现快速充电的大功率直流充电机系统及快速充电方法,涉及充电技术领域。控制器可以统计多个接入的大功率直流充电机对应的车辆的充电电池的第N+1剩余电量的第N+1方差;将第N方差与N+1方差的差值确定为第N方差降低速率,若第N方差降低速率与第N‑1方差降低速率的差值大于设定的速率阈值,采用强化学习模型更新功率分配网络模型配置的网络参数。控制器根据功率分配策略,控制功率分配单元分别向多个接入的大功率直流充电机分配充电功率,以使多个接入的大功率直流充电机分别根据分配的充电功率对多个车辆的充电电池进行充电,如此,可以最大程度减短同时充满多个车辆的充电电池的电量的时间。
