BATTERY MANAGEMENT SYSTEM

A system and method for determining an internal state of a battery that synchronizes the overall available charge and discharge power with the present charge and discharge current limits. The system may be operable to determine a current limit for the battery according to an internal state of the battery, a voltage based current limit, and a merged current limit. The system may also be configured to determine an expected voltage based on the current limit, and to optionally determine an overall available power output based on the current limit and the expected voltage.
