Energy Management Systems (EMS) are the "brains" of any Battery Energy Storage System. These systems oversee the operation of the BESS by monitoring, controlling, and optimizing the flow of electricity between the batteries, inverters, and the grid.
The flow battery concept permits to adjust electrical power and stored energy capacity independently. This is advantageous because by adjusting power and capacity to the desired needs the costs of the storage system can be decreased.
Flow batteries: Design and operation. A flow battery contains two substances that undergo electrochemical reactions in which electrons are transferred from one to the other. When the battery is being charged, the transfer of electrons forces the two substances into a state that''s “less energetically favorable” as it stores extra energy.
