Abstract
A system, a method, and an article of manufacture for determining an estimated battery cell module state indicative of a state of a battery cell module of a battery pack are provided. The method includes measuring at least one of a battery cell module voltage, a battery cell module current, and a battery cell module temperature. The method further includes determining the estimated battery cell module state of the battery cell module at a predetermined time based on an estimated battery pack state and at least one of the battery cell module voltage, the battery cell module current, and the battery cell module temperature. The method further includes storing a vector corresponding to the estimated battery cell module state in a memory.
Claims8
A system for determining an estimated battery cell module state indicative of a state of a battery cell module of a battery pack, comprising:
- a voltage sensor electrically coupled to the battery cell module, the voltage sensor configured to generate a first signal indicative of a battery cell module voltage;
- a current sensor electrically coupled to the battery cell module, the current sensor configured to generate a second signal indicative of a battery cell module current;
- a temperature sensor disposed proximate the battery cell module, the temperature sensor configured to generate a third signal indicative of battery cell module temperature;
- and
- a computer configured to receive the first, second, and third signals, the computer is further configured to determine the estimated battery cell module state at the predetermined time based on an estimated battery pack state and at least one of the first, second, and third signals, the computer further configured to store a vector corresponding to the estimated battery cell module state in a memory.
A computer readable medium having computer-executable instructions for performing a method for determining an estimated battery cell module state indicative of a state of a battery cell module of a battery pack, the method comprising:
- determining the estimated battery cell module state of the battery cell module at a predetermined time based on an estimated battery pack state and at least one of a battery cell module voltage, a battery cell module current, and a battery cell module temperature;
- and
- storing a vector corresponding to the estimated battery cell module state in a memory.
