The essentials

  • 1An electric car appraisal costs a fixed auf Anfrages at DIAVAG, including the Premium Battery Test and mobile call-out.
  • 2The battery's State-of-Health (SoH) is the most important factor for residual value and is documented in detail.
  • 3The appraisals are BVSK-compliant and independent under ISO 17020 Type A, making them usable for legal purposes.

Tuesday morning in an underground car park in Berlin-Mitte. A Tesla Model Y is due for valuation as the lease is about to expire. The owner needs clarity on the current market value and the condition of the high-voltage battery. In such situations, a standardized appraisal is essential. While conventional inspection organizations often only perform a visual inspection, DIAVAG relies on an in-depth technical analysis on site. The appraiser arrives at the vehicle's location within 24 hours of booking. Using calibrated hardware, not only the bodywork is checked, but also the heart of the EV: the battery.

The Cost Structure for Electric Car Appraisals in Detail

The cost of a professional appraisal for electric vehicles differs significantly from conventional combustion-engine valuations. This is primarily due to the diagnostic depth required for the high-voltage battery. DIAVAG follows a transparent fixed-price model here. A premium appraisal for an electric car costs auf Anfrages. This amount covers all services: from the appraiser's travel within the regions of Hamburg, Berlin and Munich to the final preparation of the BVSK-compliant report. There are no hidden fees for mileage or the use of specialized hardware.

By comparison, many traditional appraisal offices charge according to the Judicial Remuneration and Compensation Act (JVEG) or individual hourly rates. This often leads to a lack of predictability in total costs, especially when complex battery diagnostics are involved. At DIAVAG, the Premium Battery Test is an integral part of the 299-euro package. This is equally important for private sellers, buyers and commercial fleet operators seeking a reliable basis for calculation. The appraiser's independence is maintained, as DIAVAG does not purchase vehicles or broker repairs.

The Premium Battery Test as a Decisive Value Factor

The traction battery is the most valuable individual component of an electric car and can account for up to 40 percent of the vehicle's total value. An appraisal that only assesses visual condition and tire tread depth is therefore insufficient for determining a market-appropriate price. The Premium Battery Test, which is included as standard at DIAVAG, provides precise data on the State-of-Health (SoH). Parameters such as cell balance, actual capacity in kilowatt-hours, internal resistance and the charging curve are analyzed. This data is essential for determining replacement value or sale value.

Without such an in-depth diagnosis, the battery's condition remains an unknown, which often leads to significant price deductions in transactions. A certified SoH value serves as objective proof of the storage system's performance. This is particularly relevant given the upcoming EU Battery Passport, which becomes mandatory from February 2027. DIAVAG is already preparing vehicle owners for these regulatory requirements today. The appraisal documents the energy condition in such detail that it can also serve as reliable evidence in legal disputes, for instance in inheritance or divorce matters.

Mobile Service and On-Site Efficiency

A key advantage of the DIAVAG system is mobility. The appraiser comes directly to the vehicle's location, whether that's a private garage, a company yard or a public parking space. This saves the customer the time-consuming trip to a stationary inspection center such as TÜV or DEKRA. The appointment usually takes place within 24 hours of booking. The actual on-site inspection is optimized for maximum efficiency and takes under 15 minutes. This is made possible by a standardized workflow and the use of a specialized hardware kit.

Despite the short time on site, the appraisal's data density is above average. While the appraiser checks physical features and paint layer thickness, the software reads out all relevant system data via the OBD2 interface. The results are captured digitally and transmitted to the back office, where a senior inspector conducts a final review and signs the appraisal. The customer receives the finished PDF document the same day. This speed is a decisive factor when it comes to short-notice sales decisions or documenting insurance claims.

Legal Certainty Through BVSK and ISO 17020 Type A

The quality and legal usability of an appraisal depend largely on the qualification of the person preparing it and the organization's independence. DIAVAG appraisers work according to the standards of the German Federal Association of Freelance and Independent Motor Vehicle Appraisers (BVSK). DIAVAG also operates as an inspection body under ISO/IEC 17020 Type A. This represents the highest level of independence, as there are no economic ties whatsoever to vehicle trading, insurance companies or repair shops. Such an appraisal is therefore accepted by banks, insurers and in legal contexts as an objective basis.

For lawyers and notaries, this provides the necessary security when valuing assets in client matters. Whether settling estates among heirs or determining value in divorce proceedings: a standardized document signed by a senior inspector minimizes the risk of objections. Optionally, the appraisal can be secured with a notarial hash on the Polygon blockchain, which technically rules out any subsequent manipulation of the data. However, for specific legal questions, qualified legal counsel should always be consulted, as DIAVAG provides only technical and value-related facts.

Comparison of Appraisal Models

To make it easier to choose the right appraisal, it helps to compare the available market options. Classic inspection organizations often focus on the periodic roadworthiness test and typically offer valuations only as an add-on service, frequently without in-depth battery diagnostics. Pure online estimation services, on the other hand, rely solely on algorithms and do not take into account the individual technical condition of the vehicle on site.

This comparison shows that DIAVAG's fixed price of auf Anfrages combines a comprehensive technical inspection with high legal relevance, going far beyond simple market value estimates.

The Technical Inspection Workflow

The on-site process follows a strict protocol to ensure the comparability of results. First, the vehicle is identified in accordance with StVZO and FZV regulations. The hardware kit is then used, which includes an OBD2 scanner, a paint layer thickness gauge and a tire tread depth gauge, among other tools. A digital multimeter is used to check the basic electrical systems. Particularly important is the standardized photo documentation, which comprehensively captures all value-relevant areas and any defects.

Data from the Premium Battery Test is collected during the on-site visit. The control units are read out to assess the history of charging cycles and thermal stress. This information feeds directly into the calculation of the State-of-Health. Since DIAVAG covers seven different asset classes, including home storage systems and boats, the software is optimized for the specific requirements of lithium-ion storage systems in different environments. The result is a technical profile of the vehicle that goes far beyond a superficial assessment and gives the customer a well-founded basis for decision-making.

Solutions for Dealers and Fleet Operators

For commercial customers such as car dealerships, leasing companies or fleet operators, DIAVAG offers scalable solutions. From a volume of 50 appraisals per month, individual terms are agreed. A key aspect for B2B customers is integration into existing processes. Via a DMS API, appraisals can be fed directly into Dealer Management Systems. This speeds up the trade-in of electric vehicles and increases transparency for the end customer.

In addition, independent appraisers have the option of purchasing the standardized hardware kit including software for a list price of auf Anfrages. This allows smaller offices to add highly specialized battery diagnostics to their own portfolio without having to develop their own software solutions. Data is always stored in compliance with GDPR on servers within the European Union. Standardization of processes ensures that every appraisal, regardless of the technician who carried it out, meets CITO GmbH's high quality requirements.

Future-Readiness and Regulatory Standards

The automotive industry is undergoing profound change, which is also transforming appraisal requirements. With EU Machinery Regulation 2023/1230 and the upcoming EU Battery Passport, documentation obligations for technical assets are increasing. DIAVAG has already integrated these developments into its current workflow. An appraisal prepared today already accounts for the parameters that will be required in the future for a vehicle's digital life history. This preserves the vehicle's value and makes future resale easier in an increasingly regulated market.

The combination of technical precision, mobile flexibility and a clear fixed-price model positions DIAVAG as a modern service provider in a segment traditionally characterized by rigid structures. Whether for private owners of a Tesla or managers of large electric fleets: DIAVAG's independence guarantees that the valuation is based solely on hard data and professional expertise. This builds trust among all parties to a transaction and ensures fair pricing based on the actual technical condition.
