Fast, easy and reliable
DEKRA's unique battery test consists of two parts. A statistical test where you first read data from the electric car's OBD socket using a dongle. In the subsequent dynamic test, the electric car is accelerated from standstill to around 40 km/h with the measuring equipment installed. The test takes a total of 15 minutes and is carried out at one of DEKRA's inspection stations.
- The big advantage is that we can provide a very reliable assessment in a very short time. No one else on the market offers such a fast method today, continues Anders Gagner-Geeber.
Overall, the static and dynamic test gives a result that reproduces the degradation of the electric car's battery. On the scale, 100 means the battery is brand new.
A used electric car shows a lower value due to factors such as age, number of charges and mileage.
The state of health of electric car batteries decreases relatively evenly at first, but after the battery has lost 20–30 percent of its initial capacity, the state of health falls faster. The loss of both range and performance thus has a greater impact on the car's usability.
Increased security for buyers and sellers
With DEKRA's battery test, the state of health can not only be accurately measured, but also give a clear and comparable result on the actual battery capacity and thus an indication of where the battery is in the degradation process. This allows you to compare the test results between different electric cars, which provides a unique opportunity for buyers of a used electric car to reliably compare different electric cars with each other.
DEKRA's battery test will be just as important in the assessment of a used electric car as today's product declaration, VDN. A knowledge that is invaluable when buying a used electric car.
- This is good news for car dealers, leasing companies and private individuals alike, as it provides a basis for more transparent sales negotiations, concludes Anders Gagner-Geeber.
