What is a battery energy storage system (BESS)?

The implementation of intermittent, renewable electricity generation requires an increase in electricity storage. Battery energy storage systems (BESS) are a type of storage solution that stores electrical energy using batteries and other electrical devices.

What is a battery management system (BMS)?

In general, BESS includes the energy storage in battery cells, their encasing, and the auxiliary systems e.g., electrical cables, power conversion, monitoring, and control systems. Monitoring and control systems comprise the basic functionalities of battery management system (BMS), which among other, controls the safety of BESS.

Are stationary Bess batteries safe?

Here, we summarize various aspects and present mitigation strategies tailored to stationary BESS. Although some residual risks always present with Li-io batteries, BESS can be made safe by applying design principles, safety measures, protection, and appropriate components.

What is a stationary battery energy storage system?

Stationary battery energy storage systems (BESS) have been developed for a variety of uses, facilitating the integration of renewables and the energy transition. Over the last decade, the installed base of BESSs has grown considerably, following an increasing trend in the number of BESS failure incidents.

Are battery storage systems safe?

However, the Library said that batteries used in storage systems may need to meet existing product safety standards, especially where second-life batteries are used. It also noted that wider grid-scale systems are subject to general fire safety and health and safety legislation, depending on how and where they are installed.

What are the requirements for a Bess battery?

For more than 2 kWh this regulation dictates additional requirements like carbon footprint, recycling, performance and durability, labelling and marking, and battery passport regulations. Chapter II of EU Battery Regulation describes the safety of stationary BESS.
