Audi’s new BattMAN software plays God with the batteries in VW’s electric vehicles
Have you ever wondered what happens to all the batteries in our electric cars when the vehicle has reached the end of its life? Here is the ultimate inspector who will decide whether or not to get a second chance in life.
The software analyzes the batteries in a few minutes and sorts them into three categories depending on their condition. According to Axel Vanden Branden, quality engineer at Audi Brussels, all important parameters of a cell are measured and a traffic light system shows their status, whereby green means that a cell is still in order, yellow means that a further check is recommended and red means that the cell is out of order.
In the best case scenario, the battery is reconditioned after a repair and used as a spare part for an electric car.
Another option is to use batteries that are still in the middle state for use outside of electric vehicles. For example, a battery could be repurposed for mobile charging robots, forklifts, driverless transport systems and more.
In the third and darkest of the scenarios, unhappy, dead batteries can still do something good in this world by efficiently recycling them in the aforementioned pilot plant. Unrecoverable, tired batteries are being dismantled down to their basic materials such as copper, aluminum, plastics and the “black powder” that contains their most useful components: lithium, nickel, cobalt, graphite, manganese. These materials will be recycled and used in VW’s future cell production, with recycled batteries being just as effective as new ones, according to the company.
