Health Management of Rechargeable Batteries
First Claim
1. A rechargeable battery system, comprising:
- a rechargeable battery; and
a battery health management unit operatively coupled to the rechargeable battery and including a state of health module configured to estimate a battery health by receiving battery-related data and predicting one or more failure modes, wherein the battery-related data comprises real-time data relating to varying rates of discharge of the rechargeable battery during use and varying depths of discharge of the rechargeable battery during use.

Abstract
Systems and methods for health management of rechargeable batteries are disclosed. In one embodiment, a rechargeable battery system includes a rechargeable battery, and a battery health management unit operatively coupled to the rechargeable battery and including a state of health module configured to estimate a battery health by receiving battery-related data and predicting one or more failure modes. The state of health module may further include a prognostic failure mode component configured to combine at least one flight data variable with at least one model-based prognostic. In alternate embodiments, the battery health management unit may further include a state of life module and a state of charge module.
