What the report covers
- State of health. Usable capacity compared with the battery when it was new, where the manufacturer's data allows it
- Balance. The voltage spread across cells or modules, with any weak ones flagged
- Fault history. Stored high-voltage and charging codes, including old ones a seller may have cleared
- Charging. A live charge test to confirm the car accepts and holds a charge
- Isolation. A high-voltage insulation check for hidden wiring or moisture problems
- Recalls. Open recalls and service campaigns on the VIN
Who it's for
Buyers. Have the seller bring the car in, or bring it yourself during a test drive. You leave with a written report you can use to negotiate, or to walk away.
Sellers. A clean report answers the first question every used EV buyer asks.
Owners. If your range has dropped or charging has slowed, the report shows whether the battery is the cause or something else, such as a cooling or charging fault.
What data we can see
Each manufacturer exposes different battery data to scan tools. Some report a direct state-of-health figure, others only cell voltages and temperatures. We will tell you up front what your make and model allows, so you know exactly what the report will include.
Plug-in hybrids too
Plug-in hybrids like the Toyota Prius Prime and RAV4 Prime, BMW 330e and X5 plug-ins, Volvo Recharge and Range Rover plug-ins have smaller batteries that see deeper daily cycles. A report is just as useful on these.
