Monday morning at an inspection center in Berlin-Adlershof. An independent vehicle appraiser opens the DIAVAG hardware case to appraise a Tesla Model Y. Instead of manual checklists, he uses the automated workflow and the Premium Battery Test. The appointment takes less than 15 minutes on site. The same day, the legally sound PDF appraisal report, signed by a senior inspector, is sent to the customer. This process marks the standard for partners in the DIAVAG network. Whether as a freelance appraiser or as a dealership with high throughput: partnering with DIAVAG digitizes the classic vehicle appraisal and expands the portfolio to seven asset classes, from EVs to PV home storage systems.
The Partner Model for Independent Appraisers
For freelance vehicle appraisers, DIAVAG offers an entry into digitized value determination through the purchase of the standardized hardware case. At a list price of auf Anfrages, partners receive a fully comprehensive set of calibrated hardware and the associated software license. This case contains all the necessary tools for a professional on-site inspection: an OBD2 scanner for fault memory analysis, a device for the Premium Battery Test, a coating thickness gauge to check for accident-free condition, as well as tread depth gauges and digital multimeters.
The decisive advantage for partners lies in standardization. Every appraiser in the network follows the same workflow. This guarantees consistent quality of appraisal reports, regardless of the asset's location. The software guides the user through the documentation and ensures that all relevant data points and photos are captured in a tamper-proof manner. After completing the on-site data collection, a senior inspector takes over the final review and signing of the PDF appraisal report. This relieves the partner in the back office and ensures compliance with BVSK standards as well as ISO/IEC 17020 Type A requirements.
B2B Solutions for Dealers and Fleet Operators
Dealerships and fleet operators often face the challenge of efficiently and accurately appraising large inventories at market value. DIAVAG offers a special partner model for this, which applies from a volume of 50 appraisals per month. In this segment, individual terms are agreed that are tailored to the specific needs of the commercial customer. A core aspect of this partnership is the connection to existing dealer management systems (DMS) via a dedicated API interface.
This integration eliminates duplicate data maintenance. Information from the purchasing process or inventory management flows directly into the appraisal workflow. For dealers, this means significant time savings when taking in vehicles or regularly checking fleet residual value. Especially for electric vehicles, the integrated Premium Battery Test provides necessary security for resale. Since DIAVAG operates completely independently and does not purchase or sell vehicles, dealers receive a neutral document that also serves as objective proof to end customers or financing partners.
Expanding the Portfolio to Seven Asset Classes
While classic inspection organizations such as TÜV or DEKRA focus primarily on passenger cars, the DIAVAG partnership enables the appraisal of a total of seven asset classes. This opens up new market segments and revenue potential for appraisers. In addition to cars and EVs, the system also covers boats, construction and agricultural machinery, cargo bikes, eScooters and PV home storage systems. Each class has a specific inspection workflow stored in the software.
A partner can therefore appraise an EV in an underground garage in the morning and create a value appraisal for a sailing yacht in the harbor or a PV home storage system in a single-family house in the afternoon. Demand for legally sound valuations is particularly high in the field of home storage systems and e-mobility, as battery capacity (state of health) represents the decisive value factor here. DIAVAG's Premium Battery Test provides the necessary data on cell balance and capacity, which goes far beyond a simple basic diagnosis. This is especially relevant for real estate transactions in which installed PV storage systems must be appraised.
The Premium Battery Test as the Technological Core
In an increasingly electrified world, the battery is the most valuable component of many assets. DIAVAG has integrated the Premium Battery Test as standard into the appraisal process for EVs and home storage systems. Partners use specialized hardware for this, which allows deep insights into the chemical condition of the battery. Among other things, the state of health (SoH), cell balance, actual kWh capacity, as well as the charging curve and internal resistance, are determined.
This data is not only decisive for the current market value but also prepares partners for upcoming regulatory requirements. From February 2027, the EU Battery Passport becomes mandatory for many battery types. DIAVAG partners already work today with a system designed for these transparency requirements. For the end customer, this means maximum security when buying or selling a used electric vehicle. An appraisal report at a fixed price of auf Anfrages for premium assets includes this in-depth diagnosis, creating a unique selling point compared to competitors who merely read the fault memory.
Legal Certainty Through BVSK and ISO Standards
The acceptance of an appraisal report by insurers, banks or courts depends largely on the qualification of the author and the independence of the organization. As an inspection body, DIAVAG meets the requirements of ISO/IEC 17020 Type A, which represents the highest level of independence. Partners in the network benefit from this structure, as every appraisal report is finally reviewed by a senior inspector. All appraisers work according to the guidelines of the BVSK (Federal Association of Independent Vehicle Appraisers).
This legally sound design is particularly important for sensitive occasions such as inheritances, divorces or insurance cases. In such contexts, the appraisal report serves as an objective basis for asset division or claims settlement. In legal disputes, DIAVAG also offers the option of a notarial hash on the Polygon blockchain to prove the immutability of the document at the time of creation. Appraisers should always refer customers to specialized lawyers or notaries for specific legal questions, while DIAVAG provides the technical and professional data basis.
Efficiency Through Mobile Service and Speed
DIAVAG's business model is consistently designed for mobility. The appraiser comes to the location of the asset, whether it's a private garage, a company yard, or a marina. For partners, this means high flexibility in appointment scheduling. The promise to the customer is clearly defined: an appointment within 24 hours, a processing time of under 15 minutes on site, and delivery of the PDF appraisal report the same day.
This speed is achieved through a high degree of automation in the DIAVAG app. Standardized photo documentation ensures that no relevant views are forgotten and that image quality meets the requirements for a professional value appraisal. Data is stored in compliance with GDPR on servers within the EU. For partners, administrative effort is reduced to a minimum, as the creation of the final report and archiving are supported by the system. This enables a higher number of inspections per day compared to traditional, manual appraisal procedures.
Comparison of Partner Models and Terms
The following table provides an overview of the various entry options into the DIAVAG network and the associated conditions.
| Feature | Freelance partner | Dealer / Fleet |
|---|---|---|
| Entry threshold | Purchase hardware case | From 50 appraisals / month |
| Investment | auf Anfrage list price | Individual terms |
| Target group | Independent appraisers | Dealerships, leasing companies |
| Technology | Hardware + software license | DMS API integration |

| Support | Senior inspector review | Key account management |
Through this differentiation, DIAVAG offers a suitable technological infrastructure for both individual entrepreneurs and large organizations. While the freelance partner benefits from the brand and standardized workflow, the dealer focuses on process optimization and seamless integration into existing IT systems.
Independence as a Central Success Factor
A key pillar of the DIAVAG system is strict independence. Neither CITO GmbH nor its partners sell vehicles, insurance, or repair services. This neutrality is the prerequisite for the recognition of appraisal reports by third parties. In contrast to purchasing portals, whose valuations may be influenced by their own buying interest, DIAVAG delivers an objective market value based on technical facts.
For partners, this means high credibility in the market. A value appraisal at a fixed price of auf Anfrages for standard assets or auf Anfrages for premium assets is a transparent service without hidden costs. This price stability builds trust among both private customers and commercial clients. Independence also protects the appraiser from conflicts of interest and strengthens their position as a neutral expert in their regional area of operation. In the regions Hamburg, Berlin and Munich, this approach has already proven successful, with the nationwide rollout planned for 2026.
Future-Proofing Through Digital Standards
The digitization of the appraisal industry is irreversible. Partners who choose a system like DIAVAG early on secure a technological edge. The integration of blockchain technology for tamper protection and preparation for the EU Battery Passport demonstrate the network's innovative power. Data is stored securely in the EU and is available digitally to both the partner and the customer at all times.
In addition, the cross-asset orientation enables diversification of the business model. In times of fluctuating used-car markets, expertise in niches such as boats or home storage systems offers additional stability. Continuous development of the software and regular calibration of the hardware ensure that partners always work at the latest state of the art. Become part of this development and use DIAVAG's infrastructure to make your appraisal work more efficient and future-proof.
