Warwick University uses old batteries to build small energy storage devices to charge remote farms
With the rapid increase in the number of electric vehicles, how to recycle and reuse car batteries has become an urgent issue. According to foreign media reports, researchers at the University of Warwick’s School of Manufacturing Engineering (WMG) have found a way to not only recycle used batteries, but also re-create them into small energy storage systems (ESS) to power developing or remote communities. The retrofitted unit can store approximately 2 kWh of energy and can power small shops, farms or multiple homes.
The main researcher of the project, Professor James Marco of WMG, said: “It is generally believed that when the battery capacity of an electric vehicle drops to 80% of the initial capacity, it has reached the limit of use. Although it cannot meet the needs of the vehicle, but thinks It is still very useful for people who use batteries in a static environment.”
In order to take advantage of such partially depleted batteries and ensure that they are reliable, sustainable and inexpensive to use in remote locations, some challenges need to be overcome, such as:Is this small energy storage system compatible with older batteries and modules from other manufacturers;How to make the device easy to use and maintain, and keep it low cost.
The WMG research team, with the help of the WMG HVM Catapult and Jaguar Land Rover, set out to overcome these challenges, and Jaguar Land Rover provided Jaguar I-PACE batteries for research. The team designed a new battery management system (BMS) to make them an easy-to-carry ESS prototype with the following features:
