WEB CONFERENCE: ENERGY STORAGE
Keys to the design and operation of battery storage systems
Appropriate tools and techniques enable the safe and reliable operation and optimal design of long-life battery energy storage systems for their use in future-oriented grids.
Starting with the basics of energy storage, the audience will be led to two important topics: monitoring and energy conversion.
Both are closely related to long life expectancy, reliability, and safety of the storage systems. In this context, special ICs and techniques are also introduced to the audience. The matter of high-efficiency charging devices based on WBG components will also be addressed.
Electrical connections are of the same importance as electronics in terms of reliability. Some reasons for their failures will be described, including the resulting consequences to the system. Failure avoiding techniques will be presented.
These are the central topics that were discussed at the web conference:
- Review of energy storage basics
- Monitoring and energy conversion in bettery storage systems
- Optimal design featuring reliability and safety
- High-efficiency chargers with WBG semiconductors
- Failures in the connections: sources, implications, and prevention
Part 1 (Phoenix Contact) - The impact of connection technology on efficiency and reliability of battery energy storage systems
Battery energy storage systems (BESS) are a complex set-up of electronic, electro-chemical and mechanical components. Most efforts are made to increase their energy and power density as well as their lifetime.
While optimizing BESS, the focus is mainly directed to the electro-chemical battery cells. When talking about efficiency, the power hardware, mainly the used semiconductor components, come into mind.
This is a fair approach, since also a human body is healthy and efficient only as long as all organs are working properly - if this picture is allowed. But as soon as the organs are not supplied with blood or cannot communicate with each other, the body breaks down.
The same applies to batteries. The cells may be of high-end materials, the semiconductors may stay cool at highest currents - but if the electrical connections are not working reliably, the whole system will fail.
The talk and the discussions will adress these oftenly overlooked components of battery energy storage systems. Some reasons for possible failures will be described, including the resulting consequences to the system. And it will be elaborated, how these failures can be avoided.
Part 2 (Analog Devices) - Energy storage - The key enabler of the electrification megatrend
Renewable energy production is not aligned with load consumption of grid-connected devices: EVs through charging infrastructure, heating/cooling systems, factory machines.
Energy storage is the key enabler of the electrification megatrend, from residential to grid scale. Analog Devices help customers designing energy storage systems with focus on lifetime, reliability and safety.
This presentation starts from the basics of Energy Storage System services and why they are needed to build a sustainable grid. It focuses on the two bigger aspects of ESS: battery monitoring and power conversion.
Attendees will learn why focusing on battery monitoring designs enable longer lifetime of ESS devices, together with enhanced reliability and safety of operation. A deep dive is given into ADI battery management IC features and how ADI engineers can support building complete system platforms together with customers.
ADI solutions to drive SiC and GaN power switches in high-efficiency ESS chargers are also presented, showing attendees how to build isolated driving units with shortest time to market thanks to ADI reference designs.
