An SoH value of 100% means that the battery delivers its full original capacity. At 85%, 85% of the original usable energy is still available. The value is therefore the most important indicator of the remaining range, residual value and life expectancy of an electric car.   <\/p>\n\n<p class=\"wp-block-paragraph\">With every charging cycle, through temperature stress and chemical ageing, a lithium-ion battery gradually loses capacity. How quickly this loss occurs depends on usage behaviour, charging habits and climate \u2013 two identical vehicles of the same model year can show significantly different SoH values at the same mileage. A sound battery assessment is therefore not a box-ticking exercise but the basis of any serious pricing.  <\/p>\n\n<p class=\"wp-block-paragraph\">You can find a detailed explanation of the SoH value in our <a href=\"https:\/\/over-the-air.de\/en\/state-of-health\/soh-battery-explained\/\" data-type=\"link\" data-id=\"https:\/\/over-the-air.de\/beitrage\/soh\/soh-batterie-verstehen-was-der-state-of-health-ueber-den-akku-eines-elektroautos-verraet\/\"><strong>\u00bbguide to battery SoH\u00ab<\/strong><\/a> <\/p>\n\n<div class=\"wp-block-group ota-cta-slim has-ast-global-color-1-background-color has-background is-content-justification-space-between is-layout-flex wp-container-core-group-is-layout-9976dc6a wp-block-group-is-layout-flex\" style=\"border-radius:12px;padding-top:20px;padding-right:28px;padding-bottom:20px;padding-left:28px\">\n<p class=\"wp-container-content-9cfa9a5a wp-block-paragraph\" style=\"font-size:16px;line-height:1.5\">Registration, process and billing per query \u2013 we clarify the key details in a short conversation.<\/p>\n\n\n\n<div style=\"background:#0E2A47;border-radius:16px;padding:26px 30px;display:flex;align-items:center;gap:16px;flex-wrap:wrap;\"><span style=\"display:inline-flex;align-items:center;gap:10px;font-weight:500;color:#ffffff;font-size:15px;\"><span style=\"width:34px;height:34px;border-radius:50%;background:#FBEADF;color:#FF5400;font-weight:700;display:inline-flex;align-items:center;justify-content:center;flex:0 0 34px;\">1<\/span>Register for free<\/span><span style=\"color:#FF5400;font-weight:700;\">\u2192<\/span><span style=\"display:inline-flex;align-items:center;gap:10px;font-weight:500;color:#ffffff;font-size:15px;\"><span style=\"width:34px;height:34px;border-radius:50%;background:#FBEADF;color:#FF5400;font-weight:700;display:inline-flex;align-items:center;justify-content:center;flex:0 0 34px;\">2<\/span>Enter VIN<\/span><span style=\"color:#FF5400;font-weight:700;\">\u2192<\/span><span style=\"display:inline-flex;align-items:center;gap:10px;font-weight:500;color:#ffffff;font-size:15px;\"><span style=\"width:34px;height:34px;border-radius:50%;background:#FBEADF;color:#FF5400;font-weight:700;display:inline-flex;align-items:center;justify-content:center;flex:0 0 34px;\">3<\/span>Get report<\/span><span style=\"margin:0 auto;\"><a href=\"https:\/\/autodataexperts.de\/over-the-air\" style=\"display:inline-block;background:#FF5400;color:#ffffff;text-decoration:none;font-weight:600;font-size:16px;padding:14px 30px;border-radius:9px;\" target=\"_blank\" rel=\"noopener\">Start Step 1<\/a><\/span><\/div>\n<\/div>\n\n<h2 id=\"so-h-per-fin-abfragen-was-steckt-dahinter\" class=\"wp-block-heading\">Checking SoH via VIN \u2013 what is behind it?<\/h2>\n\n<h3 id=\"die-fahrzeugidentifikationsnummer-als-schlussel-zur-batteriehistorie\" class=\"wp-block-heading\">The vehicle identification number as the key to the battery history<\/h3>\n\n<p class=\"wp-block-paragraph\">The <strong>vehicle identification number (VIN)<\/strong> uniquely identifies every vehicle worldwide; in Germany it is also known as the FIN. It consists of 17 characters and is linked to the manufacturer backend: telemetry data, software versions and \u2013 crucially \u2013 battery data are stored there. Modern electric vehicles continuously transmit status data to the manufacturer cloud via their mobile network connection \u2013 the technological basis of this data transmission is <strong><a href=\"https:\/\/over-the-air.de\/en\/over-the-air\/ota-update-car\/\">\u00bbOTA updates\u00ab<\/a><\/strong>.  <\/p>\n\n<p class=\"wp-block-paragraph\">An <strong>SoH query via VIN<\/strong> accesses exactly this data. Instead of reading out the vehicle, the value is retrieved where it is stored anyway: with the manufacturer itself. <\/p>\n\n<h3 id=\"welche-daten-der-hersteller-liefert\" class=\"wp-block-heading\">What data the manufacturer provides<\/h3>\n\n<p class=\"wp-block-paragraph\">Depending on the manufacturer, the VIN query returns a specific SoH value as a percentage. The data comes from the vehicle&#8217;s battery management system (BMS) and is validated by the manufacturer. The assessment is therefore based on the same data the manufacturer itself uses for guarantee and warranty decisions \u2013 a reliable figure.  <\/p>\n\n<h2 id=\"methoden-im-vergleich-obd-werkstatt-und-fin-abfrage\" class=\"wp-block-heading\">Methods compared: OBD, workshop and VIN query<\/h2>\n\n<p class=\"wp-block-paragraph\">There are currently three main methods available for battery assessment. The following overview shows the operational differences: <\/p>\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th>Criterion<\/th><th>OBD diagnosis<\/th><th>Workshop visit<\/th><th>VIN query (OTA)<\/th><\/tr><\/thead><tbody><tr><td><strong>Vehicle access required<\/strong><\/td><td>Yes, with a plug<\/td><td>Yes, drop-off\/pick-up<\/td><td>No<\/td><\/tr><tr><td><strong>Workshop required<\/strong><\/td><td>No<\/td><td>Yes<\/td><td>No<\/td><\/tr><tr><td><strong>Duration per query<\/strong><\/td><td>10\u201330 minutes<\/td><td>Several hours to days<\/td><td>Seconds to minutes<\/td><\/tr><tr><td><strong>Data source<\/strong><\/td><td>Vehicle BMS directly<\/td><td>Manufacturer diagnostic device<\/td><td>Manufacturer backend<\/td><\/tr><tr><td><strong>Data reliability<\/strong><\/td><td>medium to high (device-dependent)<\/td><td>high<\/td><td>high (manufacturer-validated)<\/td><\/tr><tr><td><strong>Scalability (fleet)<\/strong><\/td><td>limited<\/td><td>low<\/td><td>high<\/td><\/tr><tr><td><strong>Workshop-related costs<\/strong><\/td><td>low<\/td><td>high<\/td><td>none<\/td><\/tr><tr><td><strong>Use when purchasing<\/strong><\/td><td>partly suitable<\/td><td>time-consuming<\/td><td>ready to use immediately<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">The VIN query is not the right choice in every scenario \u2013 for vehicles without a mobile network connection or older models without the corresponding backend connection, OBD or workshop diagnostics remain the methods of choice. For current electric vehicles with a manufacturer cloud connection, however, it is by far the most efficient method. <\/p>\n<\/blockquote>\n\n<h2 id=\"schritt-fur-schritt-so-lauft-eine-so-h-abfrage-per-fin-ab\" class=\"wp-block-heading\">Step by step: how an SoH query via VIN works<\/h2>\n\n<p class=\"wp-block-paragraph\">The operational process of a VIN-based SoH query is deliberately kept lean:<\/p>\n\n<h3 id=\"voraussetzungen\" class=\"wp-block-heading\">Requirements<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Access to a platform that provides the VIN connection to the manufacturer backends<\/li>\n\n\n\n<li>The 17-character VIN of the vehicle to be assessed<\/li>\n\n\n\n<li>A supported vehicle (see next section)<\/li>\n<\/ul>\n\n<h3 id=\"der-operative-ablauf\" class=\"wp-block-heading\">The operational process<\/h3>\n\n<ol class=\"wp-block-list\">\n<li><strong>Registration and login<\/strong> on the platform<\/li>\n\n\n\n<li><strong>Enter the VIN<\/strong> \u2013 the number can be found in the vehicle registration document, on the door pillar or behind the windscreen<\/li>\n\n\n\n<li><strong>Start the query<\/strong> \u2013 the platform forwards the request to the backend of the respective manufacturer<\/li>\n\n\n\n<li><strong>Receive the result<\/strong> \u2013 the SoH value is displayed directly; for some manufacturers, it is supplemented by additional information such as charging cycles or capacity history<\/li>\n<\/ol>\n\n<h3 id=\"ergebnis-und-interpretation\" class=\"wp-block-heading\">Result and interpretation<\/h3>\n\n<p class=\"wp-block-paragraph\">The returned SoH value is usually expressed as a percentage. Values above 90% are considered unremarkable in the first few years; values below 80% require a more differentiated assessment \u2013 especially with regard to residual value and warranty claims. There is no blanket threshold; what matters is how the value relates to age, mileage and comparable identical vehicles.  <\/p>\n\n<figure class=\"wp-block-image size-large has-custom-border\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"819\" src=\"https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin-1024x819.webp\" alt=\"\" class=\"wp-image-984\" style=\"border-top-left-radius:19px;border-top-right-radius:19px;border-bottom-left-radius:19px;border-bottom-right-radius:19px\" srcset=\"https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin-1024x819.webp 1024w, https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin-300x240.webp 300w, https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin-768x614.webp 768w, https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin-150x120.webp 150w, https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/4-stufen-soh-abfrage-mit-fin.webp 1350w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h2 id=\"welche-fahrzeuge-unterstutzen-die-so-h-abfrage-per-fin\" class=\"wp-block-heading\">Which vehicles support the SoH query via VIN?<\/h2>\n\n<p class=\"wp-block-paragraph\">Not every electric vehicle is accessible for the VIN query. A prerequisite is a continuous connection between the vehicle, the manufacturer backend and the querying platform. The following manufacturers and models are currently supported:  <\/p>\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th>Manufacturer<\/th><th>Supported models<\/th><\/tr><\/thead><tbody><tr><td><strong>Tesla<\/strong><\/td><td>almost all models<\/td><\/tr><tr><td><strong>BMW<\/strong><\/td><td>many models<\/td><\/tr><tr><td><strong>Mazda<\/strong><\/td><td>many models<\/td><\/tr><tr><td><strong>VW<\/strong> (from 09\/2024)<\/td><td>ID.3, ID.4, ID.5, ID.7, ID.7 Tourer, ID.Buzz <\/td><\/tr><tr><td><strong>CUPRA\/Seat<\/strong> (from 09\/2024)<\/td><td>Born, Tavascan<\/td><\/tr><tr><td><strong>Skoda<\/strong> (from 09\/2024)<\/td><td>Elroq, Enyaq, Enyaq Coupe<\/td><\/tr><tr><td><strong>Audi<\/strong> (from 09\/2024)<\/td><td>Q4 e-tron<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">The list is continuously being expanded. Manufacturers that are not listed cannot currently be queried via VIN \u2013 for these vehicles, OBD diagnosis or a workshop readout remain the options of choice. <\/p>\n\n<h2 id=\"praxisanwendung-gebrauchtwagen-ankauf-flotten-mietwagen\" class=\"wp-block-heading\">Practical application: used car purchasing, fleets, rental cars<\/h2>\n\n<p class=\"wp-block-paragraph\">The VIN query delivers its operational benefit above all where many vehicles have to be assessed in a short time \u2013 i.e. precisely in the core processes of dealers, fleets and rental companies. A typical use case is the advance assessment of <a href=\"https:\/\/over-the-air.de\/en\/state-of-health\/electric-car-lease-returns-battery\/\">electric car lease returns<\/a>, in which entire return cohorts are assessed via VIN before the vehicles come back. <\/p>\n\n<h3 id=\"beispiel-handler-risikoabsicherung-im-einkauf\" class=\"wp-block-heading\">Example dealer: risk protection in purchasing<\/h3>\n\n<p class=\"wp-block-paragraph\">A used car dealer receives an offer for a two-year-old electric vehicle with 45,000 km. Before purchasing, he checks the SoH value via VIN: if the value is significantly below the average of comparable vehicles, he can adjust the purchase price accordingly or withdraw from the deal. A sound assessment that previously would have required a workshop visit is completed in minutes.  <\/p>\n\n<p class=\"wp-block-paragraph\">It is precisely for this use case that autoDATAexperts has developed <strong><a href=\"https:\/\/autodataexperts.de\/over-the-air\" target=\"_blank\" rel=\"noopener\">\u00bbSoH OTA\u00ab<\/a><\/strong>, a solution that retrieves battery health directly from the manufacturer via a VIN query. Dealers receive the value after logging in and entering the VIN on their platform \u2013 billing is monthly by invoice per vehicle queried. <\/p>\n\n<h3 id=\"beispiel-flotte-restwert-steuerung\" class=\"wp-block-heading\">Example fleet: residual value management<\/h3>\n\n<p class=\"wp-block-paragraph\">Fleet managers with vehicle numbers in the hundreds manage their resale strategy based on battery health. Anyone who regularly knows the SoH value of their vehicles can remove precisely those units from the fleet at the optimal time whose residual value would drop noticeably with further capacity loss. The VIN query provides the data basis here without a single vehicle having to go to the workshop.  <\/p>\n\n<h3 id=\"beispiel-vermieter-fahrzeug-rotation\" class=\"wp-block-heading\">Example rental company: vehicle rotation<\/h3>\n\n<p class=\"wp-block-paragraph\">Rental companies typically rotate their fleets every 6\u201318 months. If the SoH value is documented transparently before resale, the proceeds from the residual value buyer can be better managed \u2013 and conversely, when buying used electric vehicles, the VIN query protects against hidden defects. <\/p>\n\n<h2 id=\"rechtlicher-und-regulatorischer-kontext\" class=\"wp-block-heading\">Legal and regulatory context<\/h2>\n\n<p class=\"wp-block-paragraph\">The importance of reliable battery data will be further strengthened by regulation in the coming years. Two developments are particularly relevant: <\/p>\n\n<ul class=\"wp-block-list ada-highlight-box\">\n<li> <strong><a href=\"https:\/\/unece.org\/transport\/documents\/2021\/03\/standards\/un-regulation-no-156-software-update-and-software-update\" target=\"_blank\" rel=\"noopener\">\u00bbUN R156\u00ab<\/a><\/strong> \u2013 the UN regulation on software updates and software update management systems \u2013 has been setting binding requirements for the secure transmission of vehicle data via mobile networks since 2024. It is the regulatory basis on which OTA-based methods such as the VIN query operate. <\/li>\n\n\n\n<li> <strong><a href=\"https:\/\/eur-lex.europa.eu\/eli\/reg\/2023\/1542\/oj\" target=\"_blank\" rel=\"noopener\">\u00bbEU Battery Passport\u00ab<\/a><\/strong> \u2013 mandatory for new EV batteries in the EU from February 2027. It will make key battery metrics, including the SoH value, digitally traceable. Anyone already working with VIN-based assessment methods today is prepared for the upcoming requirements.  <\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Both developments are turning battery data from \u00bbnice-to-have\u00ab information into an integral part of purchasing, valuation and warranty processes.<\/p>\n\n<h2 id=\"fazit\" class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p class=\"wp-block-paragraph\">The SoH query via VIN is not a niche method but the operational consequence of increasingly connected vehicles, growing EV fleets and rising demands for data transparency. For dealers, fleets and rental companies, it replaces the workshop visit with a login and delivers data directly from the manufacturer backend \u2013 reliable, fast and scalable. Anyone who integrates this process into their purchasing and valuation routines gains valuation certainty and speed where the two have so far been at odds with each other.  <\/p>\n\n<p class=\"wp-block-paragraph\">We will be happy to discuss in a personal conversation how a VIN-based SoH query can be integrated into your purchasing and valuation processes.<\/p>\n\n<div style=\"background:#0E2A47;border-radius:16px;padding:26px 30px;color:#fff;\"><p style=\"margin:0 0 10px;color:#ff8a4d;font-weight:600;font-size:13px;\">OverTheAir by autoDATAexperts<\/p><p style=\"margin:0 0 12px;color:#ffffff;font-weight:700;font-size:23px;line-height:1.25;\">The battery health comes to you.<br>Not the other way around.<\/p><p style=\"margin:0 0 18px;color:#c9d8e8;font-size:16px;max-width:46ch;\">Enter the VIN, receive the SoH report \u2013 without the vehicle on site. \u20ac29 per query, no subscription. <\/p><a href=\"https:\/\/autodataexperts.de\/over-the-air\" style=\"display:inline-block;background:#FF5400;color:#ffffff;text-decoration:none;font-weight:600;font-size:16px;padding:12px 24px;border-radius:9px;\" target=\"_blank\" rel=\"noopener\">Register for free<\/a><\/div>\n\n<h2 id=\"faq\" class=\"wp-block-heading\">FAQ<\/h2>\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1780048504384\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is an SoH query via VIN?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>An SoH query via VIN is a method in which the State of Health value of an electric car battery is retrieved directly from the manufacturer&#8217;s backend using the vehicle identification number.

As a result, its reliability is generally higher than that of generic OBD readouts with third-party devices.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780048562476\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What are the advantages of the VIN query over an OBD diagnosis?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The VIN query requires no physical access to the vehicle, no plug and no workshop. It is completed within seconds to minutes and scales easily to large vehicle fleets. It also accesses validated manufacturer data, whereas the data quality of OBD diagnoses can vary depending on the device. For current electric vehicles with a manufacturer cloud connection, the VIN query is therefore the most efficient method.   <\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anyone working with electric vehicles in the used car trade knows the problem: the condition of the high-voltage battery determines value, remaining service life and saleability \u2013 but until now, a reliable assessment required either a workshop visit or an OBD diagnosis with a plug connected to the vehicle.
