Hybrid Energy Storage Systems
Hybrid energy storage systems ( ESS ) combine the individual advantages of different storage types to realise a single ESS with enhanced power and energy capabilities . A battery-supercapacitor based hybrid ESS can reduce a battery ’ s power rating and extend its lifespan by minimising variations in battery current . |
Competitive Advantage • Novel energy storage technologies that can be customised based on industry / customer specifications , allowing rapid introduction into the market
• Ability to conduct rapid prototyping and real-time verification of advanced power electronic concepts using Opal RT / RTDS – provides fast verification and quick adoption by industry for mass production
• Power hardware-in-the-loop capabilities to enable testing at full power
Impact • Improving reliability , efficiency and flexibility in grid energy storage , rail systems , residential energy storage , and electric vehicles
Successful Applications • Developed novel DC linked and direct AC linked hybrid ( battery / ultracapacitor ) ESS – primary advantages are increased lifespan , improved efficiency , increased reliability and flexibility
|
Capabilities and Facilities • Hybrid ESS prototypes

More Information |
• Reconfigurable hybrid ESS that can be adapted online to fulfil different operating modes – feeding load from the battery system or from a backup power source , regenerative mode , intra-module balancing mode and charging mode . Unlike conventional systems , they share components among different operating modes , which makes them more compact |
