The invention discloses an electric vehicle and a charging method and device thereof and a computer readable storage medium, and the charging method of the electric vehicle comprises the steps: obtaining the maximum output capability of a charging pile, and sending a first charging instruction to the charging pile according to the maximum output capability, so as to enable the charging pile to execute the first charging instruction; after output of the charging pile is stable, whether the current charging capacity of the electric vehicle reaches the maximum output capacity or not is judged; if not, a second charging instruction is sent to the charging pile at least once, so that the output capacity of the charging pile meets the preset fast charging condition; if yes, the current charging state is kept. According to the charging method of the electric vehicle, the maximum output power point of the charging pile is searched in a self-adaptive mode, so that charging can be conducted on different charging piles according to the maximum output capacity of the charging pile, the charging speed of the electric vehicle can be effectively increased, and the charging time is shortened.

    本发明公开了一种电动汽车及其充电方法、充电装置和计算机可读存储介质,电动汽车的充电方法包括:获取充电桩的最大输出能力,并根据最大输出能力发送第一充电指令至充电桩,以使充电桩执行第一充电指令;待充电桩输出稳定后,判断电动汽车的当前充电能力是否达到最大输出能力;若否,则发送至少一次第二充电指令至充电桩,以使充电桩的输出能力满足预设快充条件;若是,则保持当前充电状态。本发明的电动汽车的充电方法通过自适应寻找充电桩的最大输出功率点,从而在不同的充电桩上都能按照充电桩最大输出能力进行充电,能够有效提高电动汽车的充电速度,缩短充电时间。
