Empowering the Grid: Battery Energy Storage Systems
EBV Elektronik, in collaboration with onsemi, delivers advanced semiconductor solutions for high-performance and reliable Battery Energy Storage Systems (BESS).
What is a Battery Energy Storage System (BESS)?
BESS plays a crucial role in building a low-carbon world by storing energy from various sources like solar, wind, and traditional grids. It's widely used in residential and commercial applications to provide backup power, shift energy consumption, and manage renewable energy efficiently.
Key Elements of a BESS:
Battery Packs
Consist of battery cells (primarily Lithium-ion) integrated into high-voltage modules for higher capacity and energy density.
BMS (Battery Management System)
Ensures batteries operate safely, monitors states, calculates real-time data, and extends operational life.
PCS (Power Conversion System)
Responsible for bidirectional conversion of electrical energy between the battery pack and the grid/load, heavily influencing system cost and performance.
EMS (Energy Management System)
A software-based command center that monitors, controls, and optimizes the system's performance, integrating data analysis for maximum efficiency.
BESS Market Information & Trends
The BESS market is booming, driven by positive decarbonization policies, rapid renewable energy development, and continuous cost reduction of Li-ion batteries. Key trends include:
Global Market Growth
Expected to reach USD 552 TWh in total capacity by 2030 (CAGR of 37%), fueled by declining Li-ion battery costs and increasing solar infrastructure deployment.
Higher Power & Voltage Systems
The trend towards 1500V DC systems reduces system losses and cable diameters. This demands robust components like 1200V or 2000V SiC MOSFETs in multi-level or two-level topologies.
Distributed & Intelligent Systems
New generation distributed BESS addresses the shortcomings of centralized systems, enabling decentralized management, easier maintenance, and enhanced system lifespan. Integration with big data analysis for predictive operations is key.
Ecosystem Integration
BESS is increasingly integrated with solar inverters and EV charging stations to mitigate grid impact, enable energy arbitrage, reduce costs, and provide emergency power, creating a more resilient energy ecosystem.
Core Technologies for High-Performance BESS
EBV Elektronik, in partnership with onsemi, provides cutting-edge semiconductor solutions essential for high-performance BESS designs:
Silicon Carbide (SiC) Devices
SiC MOSFETs and Diodes offer superior efficiency, especially in high-voltage and high-current applications, enabling high-frequency switching and reduced losses in PCS and bidirectional inverters.
Power Integrated Modules (PIMs)
onsemi's PIMs integrate SiC MOSFET and IGBT technologies, simplifying BESS power conversion stages (AC-DC, DC-DC). They offer excellent electrical and thermal performance, and higher power density.
Primary Side PWM QR Controllers
These controllers are crucial for designing efficient auxiliary power supplies in BESS, offering benefits like no optocoupler feedback (improving reliability) and optimized light-load efficiency.
Ethernet Interface Solutions
For distributed BESS with numerous PCS and control units, advanced Ethernet controllers (e.g., 802.3cg compliant) provide robust, noise-immune connectivity, reducing cabling and installation costs.
