The invention discloses a vehicle charging method and device and a vehicle. A charging circuit of the vehicle comprises a first switch and a second switch. The method comprises steps of the access number and the output voltage of charging devices of charging equipment being detected; matching an optimal charging mode of the vehicle according to the access number and the output voltage; and adjusting a connection mode of the battery modules in the battery pack according to the optimal charging mode to form a plurality of to-be-charged electronic battery packs, and controlling a plurality of charging devices of the charging equipment to simultaneously charge a plurality of to-be-charged electronic battery packs in a one-to-one correspondence manner, so when the output voltage of the charging equipment reaches the charging voltage of the battery pack, the discharge power of the charging equipment reaches the maximum power. therefore, a problem that the charging speed is low and the cost is high due to the fact that a transformer is additionally arranged for charging in the prior art is solved, the discharging power of the charging pile can be utilized to the maximum extent, the charging time can be shortened, and the cost of additionally arranging the transformer is saved.

    本申请公开了一种车辆充电方法、装置及车辆,车辆的充电电路包括第一开关和第二开关,其中,方法包括:检测充电设备的充电装置的接入数量与输出电压;根据接入数量与输出电压匹配车辆的最佳充电方式;根据最佳充电方式调节电池包内电池模组的连接方式,形成多个待充电子电池包,并控制充电设备的多个充电装置一一对应的为多个待充电子电池包同时充电,使得在充电设备的输出电压达到电池包的充电电压的同时,充电设备的放电功率达到最大功率。由此,解决了相关技术中充电速度慢以及额外增加变压器进行充电,导致成本较高的问题,不仅可最大化利用充电桩放电功率,缩短充电时间,且节省了额外增加变压器的成本。
