Second-life battery developer Connected Energy is set to install an energy storage system in the UK using 24 used Renault Kangoo electric vehicle battery packs.
The £20 million ($25 million) 300kW/360kWh E-STOR system will help optimise energy use and peak loads across a system including PV, EV chargers and heating, ventilation, and air conditioning (HVAC).
The containerised system— part of Suffolk County Council’s The Hold project— has been developed with collaborative support from vehicle OEM Renault and digital technologies firm ABB.
By using Renault’s battery performance modelling, system performance data and CFD analysis, Connected Energy is able to reduce the cost of cooling the system while increasing the efficiency and control.
The data-based design means Connected Energy can more accurately optimise how the batteries are used within any duty cycle and better manage efficiencies and degradation.
As part of The Hold project, Connected Energy will work with the University of Suffolk to allow access to the ESS for teaching and research purposes as well as projects to translate University science into practice.
