Inverters help energy storage to support EV rapid charging

Clearly, rapid charging is one of the main factors able to stimulate the increased uptake of EVs. However, as recharging rates increase and clusters of systems are installed to meet growing demand, the development constraint is fast becoming the local electricity supply network. As a consequence, Connected Energy and its partners, including Parker, set about creating the E-STOR range of energy storage systems.

Epitomising a highly successful project partnership, these modular, self-contained, expandable and portable devices are designed to 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.

Utilising proven Li-ion, 2^nd life automotive battery technology, high efficiency power conversion and state-of-the-art monitoring systems, Connected Energy’s E-STOR 50 and E-STOR 100 models are the first products in the latest 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. Furthermore, the system 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.
