Abstract
A hybrid-electric vehicle carries batteries for storing reserve electrical power. The batteries have a state of charge which is monitored by a control system. The state of charge indicates the amount of reserve electrical power available and, under some conditions, the rate at which reserve electrical power can be sourced as electric current. The vehicle further includes an internal combustion engine which can, depending upon vehicle configuration, be used to propel the vehicle, to drive an electrical machine to source electric current for storage, or to drive the electrical machine to source electric current to power a traction motor(s). The control system provides, in response to operator requests for propulsion and in response to the state of charge of the batteries, for allocating available power between propulsion and battery charging.
