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
• Hardware-in-the-loop simulation for rapid assessment of control techniques
• Hardware testing capability up to 50kVA , 1kV , 400A
• Arbin Instruments battery tester
• Cadex C8000 battery testing system with a load capture unit
• Hioki battery simulator
• GAMRY Model REF3000 potentiostat
• LiBa WorkStation
• TempEvent temperature chamber with EUCAR 5 level capability

Our Collaborators

• ABB Corporate Research Centre ( Sweden )
• Dovetail Electric Aviation

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
