Toyota battery testing: an independent SOH certificate
We test 7 Toyota models across 6 model groups. Within three minutes, you will know the value of the battery pack.
WHAT COMES OUT OF THE BATTERY PACK
What we read out from Toyotas
The Toyota lineup ranges from fully electric to plug-in hybrid, and each version requires a different readout. We retrieve the same values for both, so you can compare them side by side.
The SOH percentage: the actual capacity compared to the factory value
The cell balance: the voltage difference between the weakest and the strongest cell
The charging history: how often it has been fast-charged and how deeply it has been discharged
The warranty status of the battery pack
A comparison with similar cars of the same year of manufacture
Everything comes directly from the battery management system via the OBD port. No estimation based on age or mileage. Within three minutes, the CARA-certified certificate is ready, as a PDF and as a JPEG.
Which Toyotas we can test
Toyota mainly supplies plug-in hybrids with a small battery pack; the bZ4X is the fully electric exception. In total, there are 7 Toyota versions in our list, spread across 6 model groups, including PROACE, bZ4X, C-HR Plug-in.
We still have too few measurements from Toyota to provide a reliable picture. However, the same applies to every brand: the measurement reads the actual capacity, and this regularly turns out differently than the mileage would suggest.
What a battery pack is worth depends less on the year of manufacture than on how it has been driven. Charging behavior, depth of discharge, and the number of fast charging sessions together determine how much capacity remains. With Toyota, there is more difference between two cars from the same year than you would expect based on the mileage.
The measurement is done via the OBD port. You receive the SOH percentage, the cell balance, the warranty status, the charging history, and a comparison with similar cars, summarized in a CARA-certified certificate as a PDF and a JPEG.
