Second-life Jaguar I-PACE batteries harness renewables in energy storage system

News

JLR and Wykes Engineering are partnering on a project to slot second-life Jaguar I-PACE batteries into containers to create an energy storage system that harnesses solar and wind power.

A single Wykes Engineering BESS (battery energy storage system) uses 30 second life I-PACE batteries, and can store up to 2.5MWh of energy at full capacity. The batteries have been taken from prototype and engineering test vehicles, and JLR aims to supply enough batteries to store a total of 7.5MWh of energy by the end of 2023.

According to JLR, each BESS is capable of supplying power direct to the National Grid during peak hours as well as drawing power out of the grid during off-peak hours to store for future use. 

“One of the major benefits of the system we’ve developed is that the containers are connected to the grid in such a way that they can absorb solar energy that could otherwise be lost when the grid reaches capacity. This excess energy can now be stored in the second life I-PACE batteries and discharged later. This allows us to ‘overplant’ the solar park and maximise the amount of power we generate for the area of land we are using,” said David Wykes, MD, Wykes Engineering.
