Problems solved by technology

However, voltage is not analyzed and is an imprecise measure of the battery's ability to discharge or receive charge, thus providing only very limited information to control the overall system, resulting in somewhat inefficient operation of the battery system

Embodiment Construction

[0032] refer to figure 1 , shows a general battery-powered power supply system 10 according to a first embodiment of the present invention. The power supply system 10 can be used in electric vehicles, hybrid electric vehicles, stationary power backup systems and the like. Generally, the power supply system 10 includes a battery system 12 shown connected to an energy bus 13 which may include, for example, high current carrying cables 15 and 17 connected to a load / charger arrangement 18 . Battery system 12 may include, for example, an array of series-connected rechargeable batteries such as lead acid or gel cells. The lead acid battery may be, for example, a valve regulated lead acid (VRLA) battery.

[0033] When the power system 10 is used in an electric vehicle, the load / charger device 18 may be a combined controller / motor / generator unit capable of receiving data words representing control parameters used to adjust the field of the motor / generator. The current thereby contr...

Abstract

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 energybus (13) and the system (12) in response to the aforementioned representations.

Description

technical field [0001] The present invention relates to battery power systems, and more particularly to devices, methods, media and signals for controlling energy transfer between an energy bus and a battery system. Background technique [0002] As interest in electric vehicles, hybrid electric vehicles, and the use of battery backup systems continues to increase, so does the need for battery power systems. Many applications require the use of an array of rechargeable batteries connected in series. The ability of any individual battery in such a battery string to accept a load or receive charging current depends on that individual battery. A variety of factors affect the ability of a battery to receive or discharge charge, and these factors may include, for example, the battery's operating conditions such as temperature and state of charge. Other factors such as storage time, float voltage, float lifetime, minimum voltage, number of cycles, depth of discharge, and capacity...
