Secondary battery management system with remote parameter estimation
First Claim
Patent Images
1. A battery system comprising a processor and a memory storing instructions that, when executed by the processor, cause the battery system to:
- determine, based on an output of a sensor, at least one measured characteristic of a battery;
transmit the at least one measured characteristic from the battery system to a remote processing system;
receive by the battery system from the remote processing system, at least one parameter value calculated by the remote processing system based on the at least one measured characteristic and using a physics-based battery model, the at least one parameter value being indicative of a physical condition of the battery;
calculate by the battery system, a value indicative of a state of the battery based on the at least one parameter received from the remote processing system; and
regulate operation of the battery based on the calculated state of the battery cell.

Abstract
A battery system, having a battery management system configured to determine the state of charge and state of health of a secondary battery. The battery management system may export data to and receive inputs from a remote computer which calculates at least a portion of the state of health of the battery.
