The invention discloses a vehicle-mounted AC power supply distribution system and method, the system comprises a bidirectional OBC and an AC power supply distribution unit, the bidirectional OBC is respectively connected with an AC charging port and a plurality of AC sockets, a first relay group is arranged between the bidirectional OBC and the AC charging port, and second relay groups are respectively arranged between the bidirectional OBC and the plurality of AC sockets; the bidirectional OBC obtains charging scene information and transmits the charging scene information to the AC power supply distribution unit, and the AC power supply distribution unit judges a charging and discharging scene according to the charging scene information, obtains a control strategy according to the charging and discharging scene, and controls the first relay group and/or the second relay group according to the control strategy. According to the invention, external discharge control and internal discharge control are separately and independently controlled, and when the electric power of the electric appliance exceeds the available power supply power, one or more paths of power supply can be cut off according to a proposed strategy.

    本发明公开了一种车载交流电源分配系统及方法,其系统包括双向OBC,交流电源分配单元,所述双向OBC分别与AC充电口及多个交流插座连接,所述双向OBC与所述AC充电口之间设有第一继电器组,所述双向OBC与多个交流插座之间分别设有第二继电器组;所述双向OBC获取充电场景信息并传递给所述交流电源分配单元,所述交流电源分配单元根据所述充电场景信息判断充放电场景,并根据所述充放电场景获取控制策略,根据所述控制策略控制所述第一继电器组和/或所述第二继电器组。本发明将车外放电与车内放电控制分开独立控制,当用电器的用电功率超过了可提供的供电功率时,可以根据拟定的策略断开其一路和几路的供电。
