JAGUAR Land Rover has partnered with energy firm Pramac to develop a portable zero-emission energy storage unit powered by second-life Jaguar I-PACE batteries.

Called the Off Grid Battery Energy Storage System, Pramac's technology features lithium-ion cells from Jaguar I-PACE batteries taken from prototype and engineering test vehicles.

It will supply zero-emission power where access to the mains supply is limited or unavailable.

The partnership is the first in Jaguar Land Rover's plans to create new circular economy business models for its vehicle batteries.

As part of its commitment to net zero status by 2039, the company will be launching programmes that deliver second life and beyond uses for its electric vehicle batteries.

Second-life battery supply for stationary applications, like renewable energy storage, could exceed 200 gigawatt-hours per year by 2030, creating a global value over £25 billion.

The flagship system has a capacity of up to 125kWh - more than enough to fully charge Jaguar's all-electric I-PACE performance SUV, or to power a regular family home for a week.

Pramac directly reuses up to 85 per cent of the vehicle battery supplied by Jaguar Land Rover within the storage unit, including modules and wiring. The remaining materials are recycled back into the supply chain.

Available for commercial hire, the units are fitted with Type 2 Electric Vehicle (EV) charge connections with dynamic control and rated at up to 22kW AC to allow electric vehicle charging.

To showcase its capability, the unit helped Jaguar TCS Racing prepare for the 2022 ABB FIA Formula E World Championship during testing in the UK and Spain, where it was used to run the team's cutting-edge diagnostic equipment analysing the race cars' track performance, and to supply auxiliary power to the Jaguar pit garage.

Andrew Whitworth, battery manager atJLR's circular economy team, said: "This announcement is a great example of how we will collaborate with industry leaders to deliver our sustainable future and achieve a truly circular economy. We're delighted to be working with Pramac to use Jaguar I-PACE second-life batteries to provide portable zero-emissions power and supporting Jaguar TCS Racing this season was an excellent opportunity to demonstrate what these units are capable of."
