Mahle battery diagnostics system receives CARA certification
Mahle has been awarded the ‘Battery Health Check CARA Approved’ certification for its E-Scan function. CARA stands for Car Remarketing Association Europe, the European body representing used vehicle dealers. According to Mahle, the certification confirms that its diagnostic process complies with European quality standards. The German supplier states that the tool can determine a battery’s condition within two minutes and without the need for a test drive, positioning it as a rapid assessment solution for the used EV market.
The E-Scan is integrated as a standard function in Mahle’s TechPRO and Connex diagnostic devices. The system reads battery parameters, including the State of Health (SOH), via the vehicle’s standardised European On-Board Diagnostic (EOBD) interface and analyses them using original manufacturer data.
“We are pleased that the certification of E-Scan further strengthens our role as a competent and strong partner in the growing market for used electric vehicles,” said Felix-Matthias Walter, Director Service Solutions at Mahle Lifecycle and Mobility. “On the one hand, our partners can quickly answer customer questions about the battery health of an electric vehicle without needing to make additional investments. On the other hand, the certification now ensures comparability and transparency across national markets.”
Mahle’s primary target groups are workshops, fleet operators, and used car dealers.
For more detailed battery analysis beyond EOBD-based data, Mahle also offers its E-Health Charge diagnostic system. This solution combines OBD data with physical measurements taken during the charging process. According to the company, “this enables an in-depth, manufacturer-independent SOH diagnosis in just 15 minutes.”
Mahle Aftermarket introduced E-Health Charge in May 2024, targeting workshops specialising in electric vehicle servicing. The system performs diagnostics in parallel with charging and comprises the E-Charge 20 battery charger and the E-Health App. The charger delivers up to 20 kW and can also be used independently as a charging unit for battery-electric vehicles.
For data evaluation, Mahle collaborates with Volytica Diagnostics. The collected charging and OBD data are analysed in a secure cloud environment, compared with datasets from similar battery types and benchmarked against the original capacity of the respective vehicle model. The resulting report is then provided digitally.
