The invention relates to an electric vehicle charging method and system, computer equipment and a storage medium. The method comprises the following steps: a charging management system detects the domestic electricity consumption power of a preset load through a first detection part, obtains the remaining available electricity consumption of an energy storage battery, firstly determines the difference value between the commercial power and the domestic electricity consumption power under the condition that a charging request of a target charging pile is received, namely obtains the remaining electricity consumption power, and sends the remaining electricity consumption power to the target charging pile; and according to a comparison result between the residual electricity utilization power and the preset electricity utilization power, determining an available state of the target charging pile and a target power supply scheme, and when the available state of the target charging pile is available, indicating that the target charging pile can be supplied with power by using the residual available power after the preset load is used on the basis of the commercial power capacity. Therefore, the target charging pile supplies power to the electric vehicle, and the charging pile can be additionally arranged according to the remaining available power without transforming and expanding the commercial power capacity.

    本申请涉及一种电动汽车充电方法、系统、计算机设备和存储介质。所述方法包括:充电管理系统通过第一检测部件检测预设负载的生活用电功率,并获取储能电池的剩余可用电量,在接收到目标充电桩的充电请求的情况下,先确定市电功率与生活用电功率之间的差值,即得到剩余用电功率,根据剩余用电功率与预设用电功率之间的比对结果,确定目标充电桩的可用状态以及目标供电方案,在目标充电桩的可用状态为可用,表示可以在市电容量的基础上,利用满足预设负载使用后的剩余可用功率为目标充电桩进行供电,从而实现通过目标充电桩为电动汽车供电,无需对市电容量进行改造扩容即可依据剩余可用功率增设充电桩。
