Reception of two NiZn battery packs at the University of Genoa (2.5 kWh and 7.5 kWh): get ready for the demo cases!
The provided battery packs built by CEA and ready to be used for the demo cases and validation works in WP6, are made with Sunergy’s NiZn modules (8 cells of 100Ah in series) and the integration of sensors and battery management system (BMS) to perform a correct energy management. Battery packs were provided with their specifications, operating instructions and safety sheet to assure an efficient delivery of battery packs to the end-users and providing relevant training.
June 2023
The battery pack of 2.5kW with 2 NiZn modules (the small energy package) was provided in June 2023 to Savona Campus of the University of Genoa ready for use in WP6 validation works for industrial application. This application is actually in progress and its aim is to validate NiZn battery as energy storage for remote autonomous low voltage supply solutions. NiZn battery pack has been installed into an integrated system equipped with particular energy harvester bladeless turbo expander that can convert any fluid stream in electricity and can therefore supply dedicated sensor systems in remoted and isolated areas. In this context, NiZn batteries will ensure an increasing of the reliability of this system. This application is an opportunity to tests small energy packages of 2.5 kWh and allows to validate that the NiZn batteries technology guaranties a smooth integration in the use-case test environments.

August 2023
The big NiZn pack (battery pack of 7.5kWh with 6 modules) installed inside a specific cabinet was provided in August 2023 to the Innovative Energy Systems Laboratory (IES Lab.) in the Savona’s Campus of University of Genoa. Battery pack is now ready for use in WP6 validation work “Energy Balancing in Smart Buildings with rechargeable NiZn battery”. This application is a stationary energy storage application and aims to evaluate the performance of the NiZn batteries and the synergy with micro gas turbine, thermal energy storage and heat pump in a real civil scenario, since IES plant is connected to the local Polygeneration grid serving the Campus in terms of heat (local Heating District Network) and electricity. This application has required an inverter installation at the IES Lab for the connection of the battery pack to the smart grid. In addition, a DCDC converter allows to rise the battery pack output voltage to make it fit for the inverter. The DCDC converter has been installed inside the battery cabinet together with the BMS and related connector blocks. The battery pack is being integrated in the multi-device plant (in a “plug and forget” mode) to verify a better management of the energy shared with the grid, allowing to satisfy both thermal and electric demands. In the next month’s two validation scenarios will be tested: on-grid application and island mode. An energy management system (EMS) has been developed and will be used in the validation work. So the results will allow to validate the implementation and performances of NiZn battery pack into a multidevice plant connected to a Smart Grid.
