The TÜV-certified AVILOO Premium Battery Test provides a comprehensive and reliable assessment of your electric vehicle’s high-voltage battery. During the test, the battery’s actual usable capacity is measured under real driving conditions, and its State of Health (SoH) along with other key battery values are calculated. The result is a detailed overview of the battery’s current condition, ageing, and any potential hidden issues.
See the currently supported vehicle models below. New models are added continuously.
With the Premium Test, the high-voltage battery is discharged from full to approximately 10% charge over a period of up to seven days. During normal driving, the test device records important battery data including voltages, currents, temperatures, and other key operating parameters. The collected data is analyzed by the AVILOO system using both automated algorithms and expert review, and you will receive a detailed battery certificate by email within a few business days.
The FLASH Test is performed while the vehicle is stationary and requires no driving. Simply connect the device to your vehicle, and within a few minutes the necessary battery data is securely uploaded from the vehicle for AVILOO’s analysis.
