Systems and methods of controlling battery deterioration by controlling battery temperature during power exchange

摘要

A power exchange controller adjusts a power exchange between a plurality of batteries and an upper authority to control deterioration of a state-of-health of each of the plurality of batteries at an equivalent rate. The power exchange controller is operable to receive a total power demand from the 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 temperature of each of the plurality of batteries and determining the power exchange with each of the plurality of batteries based on the total power demand and an equalized temperature determined from each battery temperature. Each power exchange is determined so that the battery temperature of each of the plurality of batteries during the power exchange is adjusted to the equalized temperature.

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 battery temperature of each of a plurality of batteries connected to the charging stations; receive a total power demand from the power grid and each of the plurality of batteries connected to a charging station; and determine a power exchange with each of the plurality of batteries based on the total power demand and an equalized temperature determined from each battery temperature, wherein the power exchange for each of a plurality of batteries is determined so that the battery temperature of each of the plurality of batteries during the power exchange is adjusted to the equalized temperature.
