Abstract
An example operation includes one or more of: determining a degradation of a battery of each vehicle in a group of electric vehicles, wherein the degradation is at a rate greater than a threshold; determining a return when the degradation is lowered; and providing a portion of the return to each of the vehicles in the group, wherein the portion is commensurate with the lowering.
Claims20
A method, comprising:
- measuring a baseline impedance of a battery of an electric vehicle at a first point in time using a battery management system of the electric vehicle;
- iteratively measuring additional impedances of the battery of the electric vehicle at additional subsequent points in time using the battery management system;
- using a processor of the electric vehicle, determining that a rate of degradation of the battery is greater than a threshold based on a comparison of the additional impedances to the baseline impedance;
- using the processor, controlling an action of the electric vehicle to reduce the degradation;
- and
- in response to the action being performed, determining by the processor that the rate of degradation is lowered based on subsequent impedances measured by the battery management system.
