Systems and methods of controlling battery deterioration by controlling battery state-of-health during power exchange

摘要

A power exchange controller adjusts a power exchange rate between a plurality of batteries and an upper authority to modify a state-of-health of each of the plurality of batteries over time. The power exchange controller is operable to receive a total power demand from an upper authority and each of the plurality of batteries connected to a charging station and adjust the power exchange between the upper authority and each of the plurality of batteries by detecting a battery state-of-health of each of the plurality of batteries, determining the target state-of-health for the plurality of batteries based on the state-of-health of each of the plurality of batteries and determining a power exchange with each of the plurality of batteries based on the total power demand and a difference between the target state-of-health and the state-of-health of each battery.

主权项

1. A battery deterioration control system comprising:
charging stations for vehicles operable to exchange power between batteries connected to the charging stations and a power grid, the charging stations or power grid having a power exchange controller operable to control the exchange of power between the batteries of the vehicles and the power grid, the power exchange controller programmed to: receive from the charging stations a state-of-health of each of a plurality of batteries connected to the charging stations; and adjust a power exchange for each of a plurality of batteries to modify a state-of-health of each of the plurality of batteries over time based on a target state-of-health, wherein state-of-health is a ratio of current battery capacity to original battery capacity.
