The invention provides a charging current distribution method, a controller and an electric vehicle, and the charging method comprises the following steps: when M charging gun signals are detected at the same time, the maximum allowable output current of each charging gun in M charging guns and the charging gun use conditions of N charging piles connected with the M charging guns are respectively obtained in real time, m and N are both greater than or equal to 2, and M is greater than or equal to N; obtaining the maximum allowable charging current of the battery pack of the to-be-charged equipment in real time; and according to the maximum allowable charging current, the maximum allowable output current of each charging gun in the M charging guns and the charging gun use conditions of the N charging piles, the charging current is distributed to the M charging guns. According to the method, the charging current is reasonably distributed according to the magnitude of the charging current required by the equipment and the use condition of the charging pile, the charging capacity of the charging pile can be fully played in the charging process, the charging time is shortened, and therefore charging pile resources are reasonably arranged, and the high utilization rate of the charging pile is improved.
本公开提出了一种充电电流分配方法、控制器以及电动汽车,所述充电方法包括以下步骤:当同时检测到M个充电枪信号时,分别实时获取M个充电枪中每个充电枪的最大允许输出电流和M个充电枪所连N个充电桩的充电枪使用情况,其中,M、N均大于等于2,且M大于等于N;实时获取待充电设备的电池包的最大允许充电电流;根据最大允许充电电流、M个充电枪中每个充电枪的最大允许输出电流和N个充电桩的充电枪使用情况,为M个充电枪分配充电电流。该方法通过根据设备需求充电电流大小和充电桩使用情况,合理分配充电电流,能够在充电过程中充分发挥充电桩的充电能力,缩短充电时间,从而实现了合理安排充电桩资源,提高了充电桩的高利用率。
