Abstract
Approaches for charging a battery for an electric vehicle involve obtaining battery usage metrics of the battery of the electric vehicle based upon past usage of the battery and past charging of the battery. The metrics are analyzed to determine a target state of charge (SOC) for a first type of vehicle usage and determine a charging scheme as a function of time to achieve the target SOC at a first predetermined time. The charging scheme includes a first time period and a subsequent second time period, wherein an average rate of delivering charge to the battery during the second time period is greater than an average rate of delivering charge to the battery during the first time period. The battery is charged according to the charging scheme until the battery reaches the target SOC, which is less than a maximum state of charge for the battery.
