Embodiment Construction

[0023] One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be understood that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compatibility with system-related and business-related constraints , these constraints may vary by implementation. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0024] The battery pack systems described herein can be used to power various types of electric vehicles (xEVs) and other high voltage energy storage / consumption applications (eg...

Abstract

A battery system may include a battery that in operation couples to an electrical system, and a battery control module that in operation electrically couples to the battery. The battery control modulemay read battery data, estimate a state of charge of the battery based at least in part on the battery data, and estimate a state of charge error of the battery based on magnitudes of state of chargeerror sources. Additionally, the battery control module may update a state of health estimation of the battery when the state of charge error of the battery exceeds a predetermined threshold.

Description

[0001] cross reference [0002] This application requires a filing dated September 1, 2016 titled "SYSTEMS AND [0003] METHODS FOR STATE OF CHARGE AND CAPACITY ESTIMATION OF A RECHARGEABLE BATTERY", which is incorporated herein by reference in its entirety for all purposes. Background technique [0004] The present disclosure relates generally to the field of batteries and battery modules. More specifically, the present disclosure relates to estimating the state of charge and capacity of rechargeable battery packs. [0005] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the disclosure described below. It is believed that these discussions help to provide the reader with background information to facilitate a better understanding of various aspects of the present disclosure. Accordingly, it should be understood that these descriptions are to be read in this light, and not as admissions of prior art. [0...
