Mahle said its E-Scan battery diagnostics function has received certification from the Car Remarketing Association Europe (CARA), confirming the tool’s ability to assess the health of electric vehicle batteries through a short stationary test.
The certification, issued under the label “Battery Health Check CARA Approved,” is intended to verify that Mahle’s diagnostic process meets European quality standards for evaluating battery condition in used electric vehicles.

According to the company, the E-Scan system can determine the battery’s state of health (SOH) within two minutes and does not require a test drive. The tool accesses battery data via the vehicle’s European On-Board Diagnostic interface and analyses parameters using original manufacturer information.
“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.”

The E-Scan function is integrated into Mahle’s TechPRO and Connex diagnostic devices and is primarily aimed at workshops, fleet operators and used vehicle dealers.
For more detailed battery diagnostics, Mahle also offers its E-Health Charge system, which combines on-board diagnostic data with measurements taken during the charging process. According to the company, this approach enables “an in-depth, manufacturer-independent SOH diagnosis in just 15 minutes.”
Mahle introduced the E-Health Charge system in May 2024 through its aftermarket division. The solution includes the E-Charge 20 battery charger and the E-Health App, allowing diagnostics to be performed while a vehicle is charging. The charger can deliver up to 20 kW and can also operate independently as a charging unit for battery-electric vehicles.

For data analysis, Mahle works with Volytica Diagnostics. Charging and diagnostic data are processed in a secure cloud environment and compared with datasets from similar battery types, with results benchmarked against the original capacity of the vehicle model. A digital report is then generated for the user.
