Some embodiments include a system, that includes an electric motor coupled
to propel an electrical vehicle, a battery coupled to power the motor, a
preheating system coupled to preheat the battery, a battery temperature
comparator to compare a temperature of the battery to a target preheated
temperature and to provide a battery below temperature signal when the
battery temperature is below a specified temperature, a control circuit
to determine the time remaining prior to a scheduled drive start time and
to provide a preheating enable signal during a target time interval prior
to the scheduled drive start time and a further control circuit to
operate the preheating system in response to the battery below
temperature signal and the preheating enable signal.
