Peugeot e-208 Battery Test: SoH Analysis and Valuation Report

The Peugeot e-208 is based on the e-CMP platform and uses a lithium-ion battery with a gross capacity of 50 kWh. Since the battery is the most expensive individual component of the vehicle, its condition massively influences the market value. A simple look at mileage is not enough to assess wear in electric vehicles. Factors such as charging behavior, thermal stress, and the number of full charge cycles determine the State-of-Health (SoH).

A systematic battery test is especially necessary when the manufacturer's warranty of eight years or 160,000 kilometers (at 70 percent capacity) is about to expire. Without an independent appraisal, owners have little leverage against the manufacturer if capacity subjectively declines. DIAVAG provides the necessary data for this. The appraiser checks on site whether cell voltages are homogeneous or whether individual modules show signs of premature aging. This is essential for the Peugeot e-208, since although its thermal management is efficient, frequent use of 100 kW fast chargers can nonetheless accelerate degradation processes.

Unlike simple OBD2 dongles for private use, DIAVAG uses calibrated hardware that penetrates deep into the Peugeot e-208's control units. The Premium Battery Test is a standard part of the auf Anfrage Premium appraisal. This reads not only surface-level fault codes but analyzes physical parameters in real time. These include cell internal resistance, cell balance, and the actually usable energy capacity in kilowatt-hours.

The appraiser also documents the charging history, provided the system makes this data available. A high share of DC (fast) charging compared to AC charging can be an indicator of greater thermal stress. The result of this test is summarized in a BVSK-compliant PDF appraisal. This document is signed by a senior inspector, making it far more meaningful than a mere screenshot from an app. For customers in Hamburg, Berlin, or Munich, this service offers the assurance that the technical data has been verified by an independent third party.

A key advantage of DIAVAG is mobility. Traditional inspection organizations often require the vehicle to be brought to an inspection station. This is time-consuming and involves logistical effort for deregistered vehicles or fleet operators. The DIAVAG appraiser comes directly to the location of the Peugeot e-208, whether that's a private garage, a dealer's lot, or a harbor site.

The entire inspection workflow is optimized for efficiency. An appointment is usually available within 24 hours. On-site processing takes under 15 minutes. Despite this speed, quality remains high thanks to standardized processes. The appraisers use a special hardware case that, in addition to the OBD2 scanner, also contains paint thickness gauges and tread depth gauges. This way, the Peugeot e-208 is comprehensively assessed not only electrically but also mechanically and in terms of bodywork. The finished appraisal is delivered digitally the same day.

Independence is the foundation of DIAVAG's work. Unlike car-buying platforms that might have an interest in lowballing a vehicle's value, or workshops looking to sell repairs, DIAVAG is a pure inspection service provider. We sell no vehicles, no insurance, and perform no repairs. This neutrality is crucial for the acceptance of the appraisal by third parties.

A DIAVAG appraisal serves as an objective document in price negotiations. If the battery test on the Peugeot e-208 shows an SoH of 94 percent, this is a strong argument for a higher sale price. Conversely, it protects the buyer from costly bad purchases if the battery has already degraded significantly. ISO/IEC 17020 Type A compliance underscores this claim to the highest level of independence. In disputes, such as a lease return or after an accident, this positioning provides the necessary credibility with insurers and lessors.

For lawyers, notaries, and insurers, the formal quality of an appraisal is decisive. DIAVAG appraisers work according to the standards of the BVSK (German Federal Association of Independent and Freelance Vehicle Appraisers). This guarantees a professional qualification that goes beyond simple checklists. The appraisal for the Peugeot e-208 is thus admissible in court and can be used as evidence in proceedings related to inheritances, divorces, or insurance claims.

Additionally, DIAVAG offers the option to secure the appraisal with a notarial hash on the Polygon blockchain. This makes the document tamper-proof and precisely proves at what point in time which condition was documented. For legal questions, clients should always consult a lawyer or notary, with the DIAVAG appraisal providing the technical factual basis. Compliance with the JVEG (Judicial Remuneration and Compensation Act) serves as a guiding framework for the compensation and recognition of the appraiser's service in a legal context.

Transparency begins with the price. DIAVAG avoids complicated hourly billing or hidden travel costs within the regions. For the Peugeot e-208, the Premium package applies at a fixed price of auf Anfrage. This price includes the complete vehicle inspection, including the Premium Battery Test and legally sound documentation.

For commercial customers such as car dealers or fleet operators who need more than 50 appraisals per month, DIAVAG offers individual terms. An API connection to existing dealer management systems (DMS) is also possible, seamlessly integrating the valuation process into the dealership's workflow.

From February 2027, the EU Battery Passport will become mandatory for new electric vehicles. This digital pass is meant to contain information about the origin of raw materials, the CO2 footprint, and the current condition of the battery. DIAVAG is already prepared for these regulatory requirements today. Our appraisals already capture many of the data points that will be legally required in the future.

Owners of a Peugeot e-208 already benefit from this standardization today. A detailed battery condition report will become a basic requirement for every change of ownership in the future. By using professional diagnostics early, sellers secure an edge in the market. Data storage is GDPR-compliant on servers within the EU, which is an important criterion for company fleets and institutions when selecting an appraisal service.

The market value of a used Peugeot e-208 is largely determined by the remaining capacity of the battery. A vehicle with an SoH of 98 percent achieves significantly higher prices than an identical model with only 88 percent. DIAVAG uses current market data and technical reference values to precisely determine replacement value or trade-in value. Regional market fluctuations in the regions of Hamburg, Berlin, and Munich are also factored in.

In addition to the battery, other value-relevant factors are also checked. The paint thickness gauge uncovers repainting that could indicate accident damage. The OBD2 scanner checks the fault memory for hidden defects in the power electronics or the onboard charger. This holistic approach distinguishes DIAVAG from pure battery test providers. The result is a document that reflects the overall condition of the asset and thus represents a reliable basis for financing or insurance contracts.

The process begins with online booking at diavag.com. Within 24 hours, the appraiser appears at the agreed location. First, a visual inspection of the Peugeot e-208 is carried out, followed by the paint layer measurement and tire inspection. The vehicle is then connected to the diagnostic interface. During the Premium Battery Test, cell voltages are analyzed under load and at rest to obtain a precise picture of cell balance.

All relevant conditions are photographically documented. These photos are part of the appraisal and serve as evidence. Once measurements are complete on site, the data is transferred to the back office, where a senior inspector checks plausibility and finally signs the appraisal. The customer receives the PDF document by email the same day. This highly efficient process saves time while still offering the depth of a classic expert inspection.
