Abstract
An energy storage system comprises a set of swappable battery modules positioned in battery slots with a battery module being controlled by a control switch. The control switches are linkable to form a charging control chain and/or a discharging control chain respectively to control sequential charging/discharging, parallel charging/discharging, and segmented charging/discharging among the set of battery modules in the energy storage system. Methods to detect defective battery module in a battery slot are also presented. The energy storage system can be configured in an AC power distribution environment, a DC power distribution environment, or in an EV. The energy storage system is scalable, automatically reconfigurable and accepts AC power and regenerated DC power.
