The first second life batteries of Connected Energy’s optimized generation will provide power for the County Council’s sensitive archive. The heritage facility called The Hold is due to open later in 2020; to create a controlled climate for the housed materials and to help optimize the energy use as well as peak loads, the key part will be Connected Energy’s 300 kW/360kWh E-STOR System. It also includes PV and EV chargers and critical HVAC.
The containerized systems include 24 second life batteries formerly used in Renault Kangoos that were reworked with support from Renault and ABB.
“Second life systems can have different objectives,” says Connected Energy SEP Matthew Lumsden, “the cost of the batteries is lower than for new lithium ion systems, so the degradation and overall cycle cost is lower. This means that duty cycles that are uneconomic for new systems can be viable for second life systems. The data-based design that has now been undertaken means we can more accurately optimize how the batteries are used within any duty cycle and better manage efficiencies and degradation.”
