This lets the user determine a battery’s overall state of health. Then a traffic light system indicates the status cell by cell – green means a cell is in good order, yellow means it requires closer inspection, and red means the cell is out of order.” The system then detects and displays any error messages as well as insulation resistance, capacity, temperatures, and cell voltages.Īxel Vanden Branden, Quality Engineer at Audi Brussels, explains: “We are able to measure all a cell’s most important parameters. Previously, this process took several hours.Īfter plugging in the low-voltage connectors, the device first checks whether the battery is even able to communicate and transfer data. After several months of programming and testing, BattMan ReLife emerged as the new analysis solution that provides a reliable first assessment of a battery in just a few minutes to help set its further course. It is already in use as a diagnostics tool for several brands of the Volkswagen Group.īattMan then underwent further development in cooperation with recycling experts at Volkswagen Group Components prior to the opening of the pilot plant for battery recycling in Salzgitter. The first version of the BattMan (Battery Monitoring Analysis Necessity) software was developed by the Audi Brussels quality management department for the quick and reliable analysis of Audi e-tron’s01 high-voltage battery. Starting immediately, the quick check system will be used as a means of initial diagnosis in battery recycling at the pilot plant that Volkswagen Group Components has been operating in Salzgitter since the beginning of the year.ĭepending on the capacity that the inspection system detects, a high-voltage battery may be reused in a vehicle either in whole or in part, receive a second life as a mobile or stationary energy reservoir, or the material might be returned to cell production by means of an innovative recycling process. The question is on the minds of everyone who is interested in e-mobility: What happens to the battery when an e-vehicle has reached the end of its service life? The answer is simple: The new analysis software BattMan ReLife checks their state of health in just a few minutes.
