Tuesday morning in a garage driveway in Berlin-Zehlendorf. A Peugeot e-208 in Vertigo Blue stands ready. The owner wants to sell the vehicle privately, but the prospective buyer is hesitant about the remaining battery capacity after 45,000 kilometers of mileage. The DIAVAG appraiser arrives on time, opens his hardware case and begins the standardized inspection. In under 15 minutes, the Premium Battery Test is performed to determine the exact State of Health (SoH). Without a workshop visit and without long waiting times, the seller receives a legally sound appraisal the same day, documenting the value of the EV in black and white.
Why a battery test is essential for the Peugeot e-208
The drive battery is the most valuable component of the Peugeot e-208. With a gross capacity of 50 kWh, it not only determines the range but also significantly impacts the vehicle's resale value. Since lithium-ion batteries degrade through charge cycles, thermal stress and calendar aging, simply looking at the mileage isn't enough to assess the actual condition. A vehicle with 50,000 kilometers that was primarily charged at DC fast-charging stations can have worse cell balance than a vehicle with 80,000 kilometers that was gently charged via an AC wallbox.
An independent battery test creates transparency here. It determines the State of Health (SoH), i.e. the battery's condition compared to new. For buyers, this figure is the most important basis for decision-making, minimizing the risk of an expensive battery failure outside the manufacturer's warranty. Sellers, on the other hand, use the appraisal as an objective price anchor in negotiations. Without such proof, blanket price deductions are often demanded that do not reflect the vehicle's actual condition. DIAVAG offers a standardized solution for this, carried out directly at the vehicle's location.
DIAVAG's Premium Battery Test in detail
The battery test included in DIAVAG's premium package goes far beyond reading simple fault memories. While conventional diagnostic tools often deliver only superficial data, DIAVAG uses calibrated hardware for in-depth diagnostics. The appraiser connects the OBD2 scanner to the vehicle interface and reads real-time parameters from the battery management system (BMS). This analyzes the voltages of the individual cell modules as well as cell balance. A high deviation between cells can indicate emerging defects or uneven aging.
In addition, cumulative charging amounts (AC vs. DC) and the number of full charge cycles are recorded. This data feeds into the calculation of remaining capacity in kilowatt-hours (kWh). The result is a detailed report that precisely states the SoH value as a percentage. This process is optimized for the Peugeot e-208 and takes into account the specific characteristics of the installed cell chemistry. Since DIAVAG does not sell or repair vehicles, the assessment remains completely neutral and objective. This is a decisive advantage over workshop tests, where vested interests may often take precedence.
Mobile service vs. stationary workshop visits
A key advantage of DIAVAG is its mobility. Traditionally, vehicle owners had to schedule an appointment at an authorized dealer's workshop for a battery test, bring the vehicle there, and often wait several hours or even days for the result. This involves considerable logistical effort and lost time. DIAVAG reverses this principle: the appraiser comes to the asset. Whether in a home garage, at a dealer's yard, or at the workplace, the inspection takes place wherever the vehicle is located.
This mobile approach is particularly advantageous for real estate transactions (when a home energy storage system needs to be assessed) or private EV sales. The appointment is usually scheduled within 24 hours of the request. The actual on-site data collection takes less than 15 minutes. By using a standardized hardware case and a digital workflow, every appraisal is guaranteed to have the same high quality, whether it's carried out in Hamburg, Berlin, or Munich. The time savings and convenience factor make this service the most efficient solution on the market.
Legal certainty through BVSK and ISO 17020 Type A
An appraisal is only as valuable as its legal standing. DIAVAG applies the highest standards here. All appraisers work according to the guidelines of the BVSK (German Federal Association of Freelance and Independent Motor Vehicle Appraisers). In addition, the inspection body is eligible for accreditation under ISO/IEC 17020 Type A, representing the highest level of independence. This means DIAVAG has no economic ties whatsoever to vehicle manufacturers, insurers, or workshops. This independence is essential when the appraisal is to be used in legal contexts such as inheritance matters, divorces, or insurance disputes.
Every PDF appraisal is finally reviewed and signed by a senior inspector. This guarantees consistent technical depth and compliance with the Judicial Remuneration and Compensation Act (JVEG), should a court proceeding be pursued. Optionally, the appraisal can be provided with a notarial hash on the Polygon blockchain, making the documentation tamper-proof. For complex legal questions, clients should always consult a lawyer or notary, but DIAVAG delivers the necessary technical factual basis for a sound legal assessment.
Transparent cost structure
In the appraisal industry, confusing fee schedules and hidden travel costs are unfortunately not uncommon. DIAVAG breaks with this practice through a clear flat-rate pricing model. For the Peugeot e-208, which falls into the EV category, the premium rate applies. This includes all services: the appraiser's travel within the areas (Hamburg, Berlin, Munich), the complete technical inspection including the Premium Battery Test, photo documentation, and the creation of the BVSK-compliant appraisal.
There are no hidden fees for the use of special diagnostic equipment or data archiving. This price transparency allows private customers and commercial players alike to precisely calculate the cost of the valuation. Compared to the potential losses from selling a vehicle without proof of condition, or the risk of a bad purchase, this investment is minor. For fleet operators or dealers who need more than 50 appraisals per month, DIAVAG also offers individual terms and an API connection to existing dealer management systems (DMS) to further automate processes.
The on-site inspection process for the e-208
The inspection process follows a strict protocol to ensure objectivity. First, the vehicle is identified using the vehicle identification number (VIN) in accordance with StVZO and FZV. The appraiser then conducts a visual inspection of the body and undercarriage, paying particular attention to any damage to the battery housing. A paint thickness gauge is used to check the paintwork for signs of respraying, ruling out concealed accident damage. Tire tread depth and the condition of the braking system are also documented.
The centerpiece is connecting the diagnostic hardware. While the Premium Battery Test runs, the appraiser creates standardized photo documentation of the interior and exterior. All data is transmitted to the DIAVAG software in real time. By combining human expertise with digital precision, the error rate that often exists in purely manual appraisals is minimized. After the on-site measurements are complete, the data is sent to headquarters, where the senior inspector checks its plausibility and approves the appraisal. The customer usually receives the finished document with full source traceability by email the same day.
Comparison: DIAVAG vs. conventional inspection organizations
Many vehicle owners automatically associate appraisals with organizations like TÜV, DEKRA, or GTÜ. However, there are significant differences in scope. While these organizations primarily specialize in the periodic technical inspection (HU) and general road safety, DIAVAG offers specialized value and battery diagnostics that go beyond the standard.
| Feature | DIAVAG Premium | Standard inspection organization |
|---|---|---|
| Location | Mobile, on site (garage/yard) | Stationary at the inspection center |
| Battery diagnostics | Premium Battery Test (SoH, cell balance) | Usually just basic fault memory |
| Asset classes | 30+ classes (incl. boats, home storage) | Focus on cars/trucks |
| Appointment availability | Usually 24 hours | Often longer lead times |
| Independence | ISO 17020 Type A (no vehicle trading) | Sometimes conflicts of interest |
Another advantage of DIAVAG is coverage across seven asset classes. Besides cars and EVs, boats, construction and agricultural machinery, and home energy storage systems are also assessed. This breadth of expertise is unique in the market and allows customers to have all their technical assets appraised through a single standardized service provider.
Preparing for the EU Battery Passport 2027
Regulation in the field of electric mobility is becoming increasingly stringent. Starting in February 2027, the EU Battery Passport will become mandatory for all new EV batteries. This digital passport is intended to contain information about the origin of raw materials, the CO2 footprint, and above all the current condition and remaining capacity. DIAVAG is already prepared for these requirements today. The data collected in the Premium Battery Test matches, in depth, the future requirements of the EU regulation.
For Peugeot e-208 owners, this means future-proofing. Anyone who has an appraisal carried out by DIAVAG today is already using processes that will become industry standard in a few years. This increases the acceptance of the appraisal among professional buyers and leasing companies. Especially when returning a lease vehicle, such proof can be invaluable in fending off unjustified claims regarding battery condition. Data is stored in GDPR-compliant fashion on servers within the EU, guaranteeing maximum data security.
