The invention provides a vehicle-mounted charger which is characterized in that 380V three-phase three-wire is input at an alternating current power grid side, 220V three-phase four-wire is obtained after conversion of a transformer, A, B and C phases of the three-phase four-wire are respectively connected with a single-phase charging module, and output ends of the single-phase charging modules are connected in parallel and then connected to a charging port of a battery to charge the battery; on the basis of an existing three-phase three-wire system interface, after conversion of the transformer, superposition of charging power is achieved through the multiple single-phase charging modules, and then the charging power of the battery is improved.

    本发明提供一种车载充电机,在交流电网侧,输入为380V三相三线,经过变压器变换后得到220V的三相四线,三相四线的A、B、C三相分别连接一个单相充电模块,各单相充电模块的输出端并联后连接至电池的充电端口给电池充电;在现有三相三线制接口的基础上通过变压器的转换后,通过多个单相充电模块实现充电功率的叠加,进而提高电池的充电功率。
