The present disclosure provides a flow battery module for improving energy efficiency of flow battery during dynamic load conditions. The flow battery module comprises a plurality of stacks connected in any or a combination of parallel and series. One or more pumps are configured to circulate electrolyte to the stack where ion exchange between the electrolyte occurs and a current is generated. A series of switches are configured between the flow battery and an external load or source. Based on the load or charging power stacks can be electrically and fluidically isolated thereby decreasing parasitic power consumption and self-discharge current, and as a result improving energy efficiency.

Flow battery module

The present disclosure provides an integrated flow battery stack with a heat exchanger for thermal control of the battery during operation. The battery can comprise a stack consisting a plurality of electrochemical cells, each cell comprising a pair of electrodes separated by a membrane and sandwiched between a pair of bipolar plates. Each bipolar plate is shared between two adjacent cells. The stack is connected to an external electrical circuit by two current collectors placed at each end of the stack. At least one current collector plate is thermally coupled to a heat exchange plate which can be configured to have its temperature varied through external means. The heat exchange plate exchanges heat with the battery stack and maintains the temperature of the stack, by implication, maintains the temperature of the circulating electrolytes.

Integrated flow battery stack and heat exchanger

An apparatus and method for monitoring energy storage devices is disclosed. A monitoring system that monitors an energy storage device collects and stores operating data from the device and relays that data through a communications system to one or more servers. The servers can store the operating data from each of the monitored energy storage devices.
