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.
