The invention discloses an electric vehicle charging method, a computer device and a storage medium, and the method comprises the steps: determining the constant-temperature energy consumption of a battery, the heating value of the battery in the charging process and the charging absorption energy of the battery, which are needed when the target time is reached, according to the information of the battery, the environment temperature during parking, the target time, the residual charging duration and the target charge state; and determining a value of a target moment meeting the first constraint condition and the second constraint condition, and setting a starting moment for charging the power battery of the electric vehicle according to the target moment. According to the method, the starting time of charging is set according to the target time, charging can be completed before the planned car using time according to the target charge state, on the basis that normal car using of a user is guaranteed, the total power consumption is minimized, power consumption caused by factors such as battery constant-temperature energy consumption and battery heating amount in the charging process is reduced, and the user experience is improved. Electric energy is converted into chemical energy in a larger proportion, and energy-saving charging is achieved. The invention is widely applied to the technical field of automobiles.

    本发明公开了一种电动汽车充电方法、计算机装置及存储介质,包括根据电池信息、停车时环境温度、目标时刻、剩余充电时长和目标荷电状态,确定到目标时刻时所需的电池恒温能耗、充电过程电池发热量和电池充电吸收能量,确定满足第一约束条件和第二约束条件的目标时刻的值,根据目标时刻设定对电动汽车的动力电池进行充电的起始时刻等步骤。本发明通过根据目标时刻设定充电的起始时刻,能够在按照目标荷电状态在计划用车时间之前完成充电,保障用户的正常用车的基础上,实现总电能消耗的最小化,降低因电池恒温能耗和充电过程电池发热量等因素造成的电能消耗,使得电能有更大的比例转换成化学能,实现节能充电。本发明广泛应用于汽车技术领域。
