Abstract
In accordance with exemplary embodiments, battery capacity of an electric vehicle can be automatically determined. In an exemplary method, an instruction is received to determine a battery capacity value and one or more vehicle accessories are activated to discharge the battery to a first charge level. When the first charge level is reached, a generator in the vehicle is started and used to charge the battery to a second charge level, after which the battery capacity value can be determined and stored. In accordance with the exemplary embodiments, the vehicle comprises a controller adapted to cause a battery to be discharged and charged to determine a capacity value of the battery. A plurality of accessories are configured to activate and deactivate responsive to the controller to discharge the battery, while a generator is responsive to the controller to charge the battery so that the controller can determine the battery capacity value.
