Abstract

A starter/alternator system (24) for hybrid electric vehicle (10) having an internal combustion engine (12) and an energy storage device (34) has a controller (30) coupled to the starter/alternator (26). The controller (30) has a state of charge manager (40) that monitors the state of charge of the energy storage device. The controller has eight battery state-of-charge threshold values that determine the hybrid operating mode of the hybrid electric vehicle. The value of the battery state-of-charge relative to the threshold values is a factor in the determination of the hybrid mode, for example; regenerative braking, charging, battery bleed, boost. The starter/alternator may be operated as a generator or a motor, depending upon the mode.

Apparatus and method for charging a battery in a vehicle

Patent Lemelson, J.H.

A charging system is provided for a battery or batteries located within a motor vehicle. In one form, induction energy generating means is disposed within or adjacent to the floor of a garage or a driveway on which a motor vehicle may be parked and retained for a period of time. Induction energy receiving means located within the motor vehicle converts induction energy transmitted thereto from the induction energy generating means in the floor or driveway and generates electrical energy which is either directly applied to charge a battery of the motor vehicle or to a charging unit supported bymore »« less
Battery control system for hybrid vehicle and method for controlling a hybrid vehicle battery

Patent Bockelmann, Thomas R [Battle Creek, MI]; Hope, Mark E [Marshall, MI]; Zou, Zhanjiang [Battle Creek, MI]; ...

A battery control system for hybrid vehicle includes a hybrid powertrain battery, a vehicle accessory battery, and a prime mover driven generator adapted to charge the vehicle accessory battery. A detecting arrangement is configured to monitor the vehicle accessory battery's state of charge. A controller is configured to activate the prime mover to drive the generator and recharge the vehicle accessory battery in response to the vehicle accessory battery's state of charge falling below a first predetermined level, or transfer electrical power from the hybrid powertrain battery to the vehicle accessory battery in response to the vehicle accessory battery's statemore »« less

Battery control system for hybrid vehicle and method for controlling a hybrid vehicle battery

Patent Bockelmann, Thomas R [Battle Creek, MI]; Beaty, Kevin D [Kalamazoo, MI]; Zou, Zhanijang [Battle Creek, MI]; ...

A battery control system for controlling a state of charge of a hybrid vehicle battery includes a detecting arrangement for determining a vehicle operating state or an intended vehicle operating state and a controller for setting a target state of charge level of the battery based on the vehicle operating state or the intended vehicle operating state. The controller is operable to set a target state of charge level at a first level during a mobile vehicle operating state and at a second level during a stationary vehicle operating state or in anticipation of the vehicle operating in the stationarymore »« less

Method of controlling the condition of an electric battery and apparatus for carrying out this method

Patent Froidevaux, J.H.

A method and apparatus for determining the condition or freshness of an electric battery is described. The battery is discharged with a load current having an amplitude increasing linearly with time. The battery voltage is measured as the battery is discharged and the amplitude of the load current is measured when the battery voltage decreases to a predetermined value. The measured amplitude of the load current is representative of the battery condition or freshness.
Method and apparatus to recharge a battery aboard an electric vehicle

Patent Nguyen, P.D.

A method and an apparatus to recharge a power supply aboard a vehicle which is driven by one or more electric traction motors are described. The motors are capable of being fed by the power supply aboard the vehicle or by an exterior power supply source through an energy-regulating circuit aboard the vehicle. The energy-regulating circuit is utilized to feed the electric traction motors and to recharge the power supply aboard the vehicle. The energy-regulating circuit operates at a constant rate, whereby the energy not absorbed by the one or more electric traction motors is utilized to recharge the powermore »« less
