Title: Battery system management through non-linear estimation of battery state of charge

Abstract

Systems, methods, and computer media for battery system management and non-linear estimation of battery state of charge are provided herein. Battery data is received for a time period over which a battery system has operated. The battery data represents the actual performance of the battery system over the time period. Sub-periods of charging or discharging can be identified in the time period. For the sub-periods of time, a curve can be fit to the battery data. Using the curves for the battery data for the sub-periods of time, an expected performance of the battery system, over a range of states-of-charge, can be determined. Operating instructions for the battery system can be provided based on the expected performance.

Management of gas pressure and electrode state of charge in alkaline batteries

Patent Turney, Damon; Ito, Yasumasa; Banerjee, Sanjoy

An inventive, new system that measures gas composition and pressure in the headspace of an aqueous electrolyte battery is described. The system includes a microcontroller that can use the composition and pressure information to connect a third electrode to either the anode(s) or the cathode(s) in order to balance the state of charge between the two. Results have shown that such a system can control the gas pressure inside a sealed flooded aqueous electrolyte battery to remain below 20 kPa (3 psi) and greatly extend the useable life of the battery.

In operando, non-invasive state-of-charge monitoring for redox flow batteries

Patent Deng, Zhiqun; Wang, Wei; Zang, Xiaoqin; ...

This document describes techniques and systems for in operando, non-invasive SOC monitoring of redox flow batteries. The described techniques and systems allow for accurate, inexpensive, portable, and real-time methods to measure the SOC of redox flow batteries. System operators can monitor the SOC by measuring an acoustic attenuation coefficient of the electrolyte in the redox flow battery. The acoustic attenuation coefficient is measured using an ultrasonic transducer attached to a probing cell, which is connected to an electrolyte flow of a redox flow battery. The acoustic attenuation coefficient provides an accurate, real-time SOC measurement that is generally insensitive to varyingmore » « less
