The invention discloses an intelligent charging method and system for a new energy electric vehicle battery and an electric vehicle, and the method comprises the following steps: when a received battery charging instruction is responded, obtaining a current starting SOC0, a request ending SOC1 and the temperature of each battery cell; when it is judged that the initial charging SOC0 is smaller than TBD1, the minimum value Tmin of the temperature of the battery cell is larger than the preset temperature T1, and SOC1-SOC0 is smaller than TBD2, charging is conducted at the maximum charging rate of the battery cell; and in response to the judgment that the initial charging SOC0 is smaller than TBD1, the minimum value Tmin of the temperature of the battery cell is larger than the preset temperature T1, and SOC1-SOC0 is larger than or equal to TBD2, charging is carried out at the maximum charging rate of the battery cell, in the process of charging at the maximum charging rate of the battery cell, the current SOC is obtained in real time, and in response to the judgment that the current SOC is larger than or equal to SOC0 + TBD2, charging is carried out by reducing the charging rate. According to the invention, the charging time can be shortened as much as possible to meet the actual use requirements of different users.

    本发明公开的一种新能源电动汽车电池的智能充电方法、系统及电动汽车,包括以下步骤:响应于接收到电池充电指令时,获取当前起始SOC0、请求结束SOC1以及各电芯的温度;响应于判断出充电起始SOC0<TBD1,电芯温度的最小值Tmin>预设温度T1,且SOC1‑SOC0<TBD2时,以电芯最大充电倍率进行充电;响应于判断出充电起始SOC0<TBD1,且电芯温度的最小值Tmin>预设温度T1,且SOC1‑SOC0≥TBD2时,以电芯最大充电倍率进行充电,在以电芯最大充电倍率进行充电的过程中,实时获取当前SOC,响应于判断出当前SOC≥SOC0+TBD2时,降低充电倍率进行充电。本发明能够最大可能的缩短充电时间,以满足不同用户的实际使用需求。
