— THEORY VERSUS REALITY
Measuring the battery health of an electric car
Many owners and sellers mistakenly think that the range on the dashboard, the so-called ‘guess-o-meter’, offers sufficient insight into the battery condition. This prediction fluctuates very quickly based on weather conditions, previous driving style, and outdoor temperature. In the winter, a battery sometimes seems severely degraded due to the cold, while this is purely a temperature effect.

From complex battery data to one clear conclusion
The switch to a fully electric car (EV) or a plug-in hybrid (PHEV) still raises understandable questions for many consumers and businesses. The biggest question marks almost always revolve around the condition of the battery pack. Is the battery still good? What if it breaks down soon?
At The Battery Experts, we understand that as a buyer or seller, you don't want to gamble on assumptions. You want hard certainty about the lifespan. That is exactly what we deliver, based on our philosophy: no doubt, only proof. The overall health of the battery pack is internationally referred to as the State of Health (SoH). This value directly determines the maximum range and status of the battery pack.
We believe in absolute transparency. With objective data, reliable equipment, and clear explanations, we stand alongside our customers. We are guiding, but never patronizing. No fine print or sales hype: what we measure, we say. In this guide, we explain how we translate complex battery data into one understandable conclusion, how the State of Health is calculated exactly, and how private individuals and car companies benefit directly from our certified report.

— THE SOH VALUE
What exactly is the SoH and why is that value so crucial?
The term SoH is the international technical abbreviation for State of Health. This is a percentage that compares the current maximum energy capacity of the battery pack with the original capacity on the day the car left the factory. A SoH value of 100% means that the pack is in absolute new condition. If this percentage drops to, for example, 85%, there is 15% degradation of the battery cells.
Replacing a defective battery pack can easily cost between €5,000 and €15,000 or more. It is therefore unwise to rely blindly on assumptions during a transaction. The determined SoH value, with our in-depth analysis including cell level and a final assessment based on the traffic light principle, is the hard gauge for the fair residual value and reliability of the car.

Frequently asked questions
What is a battery certificate and why do I need one?
A battery certificate is an independent report on the health (State of Health) of an electric car’s traction battery. The certificate shows, among other things, the remaining capacity, cell balance, and charging history. When buying or selling a used EV, this increases buyer confidence and leads to a higher residual value and faster sale.
Which vehicle models can be tested?
Do I need special technical knowledge to perform a battery test?
How long does it take to perform a diagnosis?
What does the SoH value (State of Health) mean?
Can the test equipment change or damage my car's settings?
What causes the battery of my electric car to deteriorate or degrade?
Can the battery certificate be used in legal disputes?
Which app should I download to take the test?
What exactly do I need before I can use the app?
