METHOD AND APPARATUS FOR CONTROLLING ENERGY TRANSFER BETWEEN AN ENERGY BUS AND A BATTERY SYSTEM BASED UPON BATTERY OPERATING CONDITION

摘要

Method and apparatus for controlling energy transfer between an energy bus(13) and a system of batteries (12) in which a control signal generator (29)operable to receive an extreme voltage representation (Ve) representing avoltage of a battery exhibiting an extreme voltage among voltages (Vn) of allbatteries (20-26) in the system (12), and a representation of a referencevoltage(Vre) derived from an operating parameter (P) associated with thebattery exhibiting the extreme voltage, is operable to produce a controlsignal for use in changing the amount of energy transfer between the energybus (13) and the system (12) in response to the aforementioned representations.
