METHOD AND SYSTEM UTILIZING PULSE VOLTAMMETRY FOR TESTING BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18201043 titled 'METHOD AND SYSTEM UTILIZING PULSE VOLTAMMETRY FOR TESTING BATTERY

Simplified Explanation

The patent application describes a battery testing system that includes a charger, a load, a processor, and a model to estimate the state of the battery based on internal parameters.

  • The system applies a predetermined voltage pulse and load to the battery, measures and logs the current through the load, and establishes a model based on the initial estimation of the battery's state and internal parameters.
  • The model outputs a model current through the load, generates an objective function based on a comparison of the measured current and model current, iteratively optimizes the battery's state estimation, and outputs the optimized estimation.

Original Abstract Submitted

A state of battery testing system is disclosed which includes a charger, a load to be coupled across the battery's positive and negative terminals, a processer adapted to apply a predetermined voltage pulse across the battery's positive and negative terminals, apply the load to the battery, measure and log current through the load as I, and establish a model based on establishing an initial estimation of state of the battery (θ), and establishing a modeled state of battery (θ) based on a plurality of internal parameters of the battery. The model is adapted to output a model current through the load, inputting θand the plurality of internal parameters of the model to thereby generate I, generate an objective function (f) based on a comparison of Iand I, and iteratively optimize θ, and output θbased on the iterations.
