Abstract
Aspects of the present disclosure involve methods, which may be to manage control of a battery such as through charging, comprising obtaining a value indicative of at least one of a dynamic state of equilibrium, periodic behavior, quasi-periodic behavior, chaotic behavior and random behavior of a battery, which may involve electrodynamic parameters of Lyapunov Exponent, Correlation Dimension, Sample Entropy and Hurst Exponent, among others, the value obtained from a voltage measurement or a current measurement from the battery, and based on the value, operating the battery to maintain the battery within one of the dynamic states.
Claims23
A method of dynamically charging a battery, the method comprising:
- obtaining a first value for a first electrodynamic parameter associated with behavior of a battery;
- comparing the first value to a first threshold value for the first electrodynamic parameter;
- and
- generating a charging signal for the battery based on the comparison of the first value to the first threshold value.
A method of characterizing aging in a battery, the method comprising:
- measuring a voltage of a battery while the battery is at rest;
- calculating at least one electrodynamic parameter from the measured voltage;
- and
- based on the at least one electrodynamic parameter, determining an amount of calendar aging associated with the battery.
A method of characterizing a battery, the method comprising:
- obtaining a first value for a first electrodynamic parameter associated with behavior of a battery;
