Abstract

A battery control module for use with a battery includes a voltage measuring module that measures battery voltage and a current measuring module that measures battery current. A power limit module communicates with the current and voltage measuring modules and once every time period estimates a battery current limit that corresponds with a future time period. The battery current limit is based on a predetermined voltage limit of the battery and a battery current and a battery voltage that correspond with a time period that precedes the future time period.

Description

technical field [0001] The present invention relates to battery systems, and more particularly to determining power delivery limits for battery systems. Background technique [0002] Battery systems can be used to provide electrical energy in a wide variety of applications. Exemplary transmission applications include hybrid electric vehicles (HEV), electric vehicles (EV), heavy duty vehicles (HDV), and automobiles with 42 volt electrical systems. Exemplary stationary application systems include backup power supplies for telecommunications systems, uninterruptible power supplies (UPS), and distributed generation applications. [0003] Examples of the types of batteries used include nickel metal hydride batteries (NiMH), lead acid batteries, and other types of batteries. A battery system may include multiple battery subpacks connected in series and / or in parallel. A battery pack may include multiple batteries connected in parallel and / or in series. [0004] Inherent proper...
