EV Batteries Avoiding the Scrap Yard!

The use of second-hand electric vehicle (EV) batteries for energy storage has gained huge popularity in recent years due to the crazy advancement of technology and the growth of renewable energy sources. These batteries, once considered end-of-life, can now be repurposed for other energy storage systems, providing a more sustainable alternative to scrapping them once they're considered unusable for a vehicle. It's also a more cost-effective solution to traditional energy storage.

The primary benefit is cost savings; these batteries are often available at a fraction of the cost of new batteries, making them an attractive option for those who want to go green while keeping costs low. Additionally, the use of second-hand batteries helps to extend the life cycle of the batteries and reduce the amount of electronic waste in landfills.

Another advantage of using second-hand EV batteries is that they are already designed to meet the high energy storage requirements of electric vehicles, making them well-suited for use in solar storage systems. These batteries have been rigorously tested for performance, durability, and reliability, and have proven to be capable of providing reliable energy storage for years.

“Is Anyone Actually Doing This Though?”

JAGUAR - Jaguar Land Rover is one of the latest manufacturers to reuse batteries, from Jaguar I-Pace development cars in partnership with energy storage systems specialist Pramac. Some 85% of the original packs, including modules and wiring, are used to make Pramac Off Grid Energy Storage Systems, with the rest being recycled. The first example has a capacity of 125kWh, which, JLR estimates, would be enough to power the average family home for a week, or fully charge an I-Pace with power to spare.

AUDI - Audi announced at the end of last year that it had partnered with power generation company RWE on an energy storage system built using decommissioned lithium-ion batteries taken from the development of Audi E-trons. In total, 60 batteries were combined to provide temporary storage amounting to 4.5MWh (4.5 million watt-hours) of energy. The system stores renewable hydroelectric energy generated by the Hengstey reservoir at Herdecke, North Rhine-Westphalia. The batteries have been installed in a purpose-built 160-square-metre hall at the reservoir’s pumped-storage plant.

NISSAN -  set up the 4R Energy Corp in partnership with the Sumito Corp even before the Leaf went on sale. Because the Leaf has been in production for 12 years now, decommissioned batteries are becoming available for other uses. The battery components are graded when they come into the plant and those getting an ‘A’ grade can be reused as an EV high-performance battery.

Those with a ‘B’ grade are good enough for industrial machinery such as forklifts or large-scale stationary energy storage in both industrial and domestic applications, where they are ideal for storing energy from solar cells in classic ‘make hay while the sun shines’ scenarios.

B2U - LANCASTER, California — In a parched corner of the Mojave Desert, car batteries are at the centre of a revolution. Instead of fading into obsolescence when they retire from propelling zero-emission Nissan Leafs, these battery packs now work together to store California solar power and discharge it in the evening when the grid needs it most.

That’s something that energy futurists talk about as a potential breakthrough, something the state of California disburses millions of dollars to research and demonstrate. But B2U Storage Solutions, the developer and owner of the Lancaster project, has been doing it for over a year, and making money at it, too.

Another huge step from the EV market leaders showing that a cleaner future is at the heart of their work!

Whether you're looking to save money or reduce your carbon footprint, using second-hand EV batteries for solar storage is an excellent choice.
