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 a voltage of a battery exhibiting an extreme voltage among voltages (Vn) of all batteries (20-26) in the system (12), and a representation of a reference voltage(Vre) derived from an operating parameter (P) associated with the battery exhibiting the extreme voltage, is operable to produce a control signal for use in changing the amount of energy transfer between the energy bus (13) and the system (12) in response to the aforementioned representations.
