Charge rate optimization

摘要

A charging system for a battery pack, including a charging station transferring energy to the battery pack at a maximum fast charge rate in a first operational mode and transferring energy to the battery pack at a slower charge rate in a second operational mode; a data collection system acquiring data indicating a state of charge of the battery pack and one or more desired charge optimization parameters; and a station control, responsive to the data and to the desired charge optimization parameters, automatically establishing a charging profile for the battery pack to assert a control signal and operate the charging station in the second operational mode whenever the charging station is able to transfer sufficient energy to the battery pack at the slower charge rate to meet an SOC target and a charge completion time target.

1. An electric charging system for an energy storage system, comprising:
a charging station electrically coupled to the energy storage system, said charging station transferring charging energy to the energy storage system at a maximum fast charge rate in a first operational mode and transferring charging energy to the energy storage system at a slower charge rate in a second operational mode, said modes responsive to a control signal; a data collection system acquiring a set of data indicating a state of charge (SOC) of the energy storage system and one or more desired charge optimization parameters; and a station control, responsive to said set of data and to said desired charge optimization parameters, automatically establishing a first charging profile for the energy storage system, with said first charging profile asserting said control signal and operating said charging station in said second operational mode whenever said charging station is able to transfer sufficient energy to the energy storage system at said slower charge rate to meet a charge target, said first charging profile asserting said control signal to operate said charging station in said first operational mode whenever said charging station is unable to transfer sufficient energy to the energy storage system at said slower charge rate to meet said charge target.
