A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
The application of batteries for domestic energy storage is not only an attractive 'clean' option to grid supplied electrical energy, but is on the verge of offering economic advantages to consumers, through maximising the use of renewable generation or by 3rd parties using the battery to provide grid services.
To cover specific lithium-ion battery risks for electric energy storage systems, IEC has recently been published IEC 63056 (see Table A 13). It includes specific safety requirements for lithium-ion batteries used in electrical energy storage systems under the assumption that the battery has been tested according to BS EN 62619.
A domestic battery energy storage system (BESS), usually consists of the following parts: battery subsystem, enclosure, power conversion subsystem, control subsystem, auxiliary subsystem and connection terminal (Figure 1). The power conversion subsystem (PCS) plays a critical role in the transfer of energy to and from the electrical supply.
However, even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, questions have been raised regarding the safety of these systems. The concern is based on the large energy content within these systems.
Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, the use of large batteries in the domestic environment represents a safety hazard.
