METHOD FOR CONTROLLING AN ENERGY STORAGE SYSTEM

摘要

A method is provided for controlling an energy storage system, the energy storage system including at least two battery modules electrically coupled in parallel to each other. The method includes receiving a signal indicative of a maximum power capability of each of the respective battery modules; assigning a power threshold limit for the at least two battery modules of the energy storage system corresponding to the lowest maximum power capability received from the battery modules; and providing a charge current to the at least two battery modules, the charge current having a current level being proportional to the power threshold limit.

1. A method for controlling an energy storage system, the energy storage system comprises at least two battery modules electrically coupled in parallel to each other, wherein the method comprises the steps of:
receiving a signal indicative of a maximum power capability of each of the respective battery modules; assigning a power threshold limit for the at least two battery modules of the energy storage system corresponding to the lowest maximum power capability received from the battery modules; providing a charge current to the at least two battery modules, the charge current having a current level being proportional to the power threshold limit; measuring a battery charge level of the battery module having lowest maximum power capability; and adjusting the charge current for reducing a difference between the battery charge level of the battery module having the lowest maximum power capability and the power threshold limit.
