A project to create a modular energy storage system that reduces the barriers to installing electric vehicle rapid chargers has been announced. Connected Energy and its partners set about creating the E-Stor range of energy storage systems.

Spearheaded by Future Transport Systems and its subsidiary Connected Energy, it uses Parker Hannifin inverter technology and involves a European automotive OEM giant, Renault, and Ricardo, a global strategic, technical and environmental consultancy.

The modular, self-contained, expandable and portable devices address the issues associated with the need to upgrade site electricity networks when installing plug-in vehicle rapid charging infrastructure. As a remotely managed solution, E-Stor offers a potentially quicker, lower cost and more flexible alternative to network infrastructure upgrades, along with a range of additional commercial and integration benefits, says Parker.

Utilising proven Li-ion, 2nd life automotive battery technology, high efficiency power conversion and monitoring systems, the E-Stor 50 and E-Stor 100 models, are the first products in the range. Supplied typically as a 50kW/50kWh nominal rated module, the integral management system optimises energy storage in relation to complementary assets and parameters in real-time. It provides detailed technical and operational reporting, along with remote site management, monitoring and control. It can also be configured as part of a wider portfolio of assets and integrated with existing building management systems.

The system comprises modular batteries and integral battery management systems, bi-directional battery charger, isolation transformer, power control module, AC/DC protection, HMI, router and communication interface. It is delivered pre-assembled directly to site and requires a minimum of preparation.
