METHOD AND APPARATUS FOR CHARGING MANAGEMENT, CHARGING DEVICE AND MACHINE READABLE MEDIUM

The present invention relates to a method and apparatus for charging management, the method comprising: using travel data of an electric vehicle of a current day to estimate a possible depth of discharge (DOD) of a battery supplying power to the electric vehicle on a second day, and a degree of ageing of the battery as of the current day, wherein the travel data indicates the variation with time of a travel speed of the electric vehicle on the current day; determining an optimal state of charge (SOC) range of the battery corresponding to the estimated degree of ageing, on the basis of information indicating optimal SOC ranges of the battery corresponding to different degrees of ageing of the battery; determining a maximum SOC of the battery when used on the second day, on the basis of the estimated possible DOD and the determined optimal SOC range; and charging the battery to the maximum SOC, when the battery can be charged for use on the second day. The method and apparatus can prolong the life of the battery supplying power to the electric vehicle.
