MAHLE Aftermarket will use the charging plug in addition to the existing OBD port for battery diagnostics of electric vehicles in the future. To this end, the service and spare parts division of the Stuttgart-based automotive supplier is collaborating with volytica diagnostics, a software developer based in Dresden. It evaluates the measured data in the cloud and provides valuable information about the state of the electric vehicle battery. In this way, projections can be made of, for example, necessary repairs. Since the start of 2022 the new diagnostics solution for passenger cars has been tested in practice together with TÜV NORD Mobilität and a well-known European fleet operator. It is expected to be available from MAHLE by the end of 2022. In the next phase, both partners want to offer the battery diagnostics for battery electric trucks and buses.A special combination of charger and diagnostic tool is used for diagnostics. In this way, MAHLE can get initial diagnostics on the condition of the vehicle battery via the vehicle’s charging socket within ten minutes. This measurement is carried out independently of the data provided by the vehicle manufacturer via the OBD diagnostics port and is therefore particularly neutral and independent.Afterwards, the battery data is comprehensively evaluated and interpreted in the volytica cloud and the result is provided to the user. With this new development, MAHLE is opening up new, future-proof business areas beyond the combustion engine for independent workshops. With the MAHLE TechPRO, MAHLE is the first supplier to enable its customers to perform basic battery diagnostics via the OBD port.With the help of battery diagnostics, up to two million tons of batteries with a value of more than EUR 50 billion can be saved annually from premature discarding and thus, for example, be given a second life. By giving a battery a second life, the battery life can be extended by an average of five years. This is an important aspect, as the Group is clearly committed to the Paris Climate Agreement and is striving to significantly reduce its carbon footprint and to use its products to contribute to environmentally compatible mobility.
