The resulting Best Practice Guide and Risk Matrix have been developed by industry associations involved in renewable energy battery storage equipment, with input from energy network operators, private certification bodies and other independent stakeholder groups and individuals, as well as consumer and electrical safety regulators.
The guide only applies to lithium-based battery storage equipment and includes:
- Battery module (BM) – one or more cells linked together. A battery module may also have incorporated electronics for monitoring, charge management and/or protection. Battery modules are installed within pre-assembled battery system equipment or pre-assembled integrated battery energy storage system equipment or as part of a master/slave configuration of such equipment.
- Pre-assembled battery system (BS) – a system comprising one or more cells, modules or battery system, and auxiliary supporting equipment such as a battery management system and protective devices and any other required components as determined by the equipment manufacturer. A pre-assembled battery system does not include a power conditioning equipment (PCE). Pre-assembled battery system equipment comes in a dedicated enclosure. The equipment is a complete package for connection to a DC bus or DC input of a PCE.
- Pre-assembled integrated battery energy storage system (BESS) – a battery energy storage system manufactured as a complete integrated package with the PCE, one or more cells, modules or battery system, protection devices, power conditioning equipment and any other required components as determined by the equipment manufacturer. Pre-assembled integrated battery energy storage system equipment is supplied in a dedicated enclosure. Integrated battery energy storage system equipment is a complete package that has AC output for connection to the electrical installation.
