DigiKey-eMag-Sustainability and Energy Harvesting-Vol 15

The expansion of renewables and a global tendency towards efficient energy consumption have boosted interest in energy storage solutions and, particularly, battery energy storage systems. Reading this article will help in understanding what these systems are about and the benefits of using them.

released from the battery during discharging can power homes, vehicles, commercial buildings, and grids. Batteries are made up of cells and can be arranged in modules, packs, and containers.

SAFETY SYSTEMS

There can be an array of safety systems, each responsible for a specific task. For example, an HVAC system enables a BESS to maintain the desired temperature and humidity through heating, ventilation, and air conditioning. A fire protection system can detect smoke and prevent fire incidents.

Battery Management System (BMS)

A BMS provides for the safe and correct operation of the battery. Every battery type has certain charging and discharging conditions. A BMS makes sure the battery stays within the required current, voltage, and temperature range. By monitoring the parameters and estimating the state-of-charge (SOC) and state-of-health (SOH) of the battery, a BMS ensures its reliable and long-lasting performance.

A BESS:What stands behind it? A battery energy storage system (BESS) is a complex solution that makes use of

rechargeable batteries to store energy and release it at a later time. BESS types correlate with electrochemistry or the battery they employ—the systems can be based on lithium-ion, lead-acid, nickel-cadmium, sodium-sulfur, and flow batteries. An energy storage system (ESS) is a broader term and it may rest on a variety of technologies other than batteries, for example, hydropower, flywheels, compressed air, and others. To understand what a BESS is and how it works, it will help to look at its structure and core elements:

storage systems supply power to thousands of homes, businesses, plants, and communities worldwide. They vary in scale and storage capacity. For example, having 13.5 kWh of usable capacity, the Tesla Powerwall is a compact device that can serve as a source of uninterrupted power for a single household. While with its total capacity of 1,600 MWh, the Vistra Moss Landing Energy Storage Facility—the world’s largest BESS—can provide energy to 300,000 homes. However, despite the difference in size and capacity, BESS can fulfill similar functions and address similar problems. Let’s consider the cases when battery energy storage can come into play.

Power Conversion System (PCS)

Through the use of a power conversion system, a BESS

converts direct current (DC) into alternating current (AC) and vice versa. AC flows from a power source and converts to DC during battery charging. When the battery is discharged, it produces DC, which is converted back to the AC necessary to power BESS applications.

Energy Management System (EMS)

Electrical energy supplied from different sources, such as solar, wind, or power stations, converts to chemical energy during the battery charging process. The energy

An EMS is a control unit of a battery energy storage system. It manages the power available in a BESS—namely, when, why, and in which amounts to accumulate or
