The SoH indicates as a percentage how much of the original capacity is still available after use and ageing. Put simply, a value of 90 percent means: the battery still stores around nine tenths of its capacity when new. We explain what lies behind the SoH value technically in our <strong><a href=\"https:\/\/over-the-air.de\/en\/state-of-health\/soh-battery-explained\/\" data-type=\"post\" data-id=\"183\">article on the SoH battery<\/a><\/strong>.   <\/p>\n\n<p class=\"wp-block-paragraph\">In addition to the pure SoH value, a meaningful certificate usually contains the vehicle identification number (<strong>VIN<\/strong>), the test date, the measurement method used and, depending on the provider, an assessment of the remaining range. Reputable certificates are issued as a <strong>digitally signed PDF<\/strong> and are thus protected against subsequent changes. <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Important for context:<\/strong> The methods assess the condition of the battery as a system. Depending on the method, they use data from the battery management system (BMS) or their own measurements. With the VIN query, the values come directly from the manufacturer\u2019s systems.  <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">A battery certificate turns the biggest uncertainty factor of a used electric car \u2013 the condition of the battery \u2013 into a documented, traceable key figure.<\/p>\n<\/blockquote>\n\n<h2 id=\"warum-der-nachweis-fur-handler-flotten-und-vermieter-zahlt\" class=\"wp-block-heading\">Why the proof matters for dealers, fleets and rental companies<\/h2>\n\n<h3 id=\"restwert-und-wiederverkaufswert\" class=\"wp-block-heading\">Residual value and resale value<\/h3>\n\n<p class=\"wp-block-paragraph\">The traction battery accounts for a considerable part of the vehicle\u2019s value \u2013 40 to 50 percent, depending on the estimate. (<a href=\"https:\/\/www.autobild.de\/artikel\/elektroauto-akku-batteriepass-22698055.html\" target=\"_blank\" rel=\"noopener\">Source: AUTO BILD \/ Federal Ministry for Economic Affairs<\/a>) Its condition therefore has a strong impact on the price. With the EV value correction, Deutsche Automobil Treuhand (DAT) has introduced a standardised procedure that incorporates the actually determined SoH value into the vehicle valuation that is decisive for the trade. (<a href=\"https:\/\/www.dat.de\/restwert-elektroautos\/\" target=\"_blank\" rel=\"noopener\">Source: DAT<\/a>) A documented, <strong>good SoH value is thus a direct lever on the calculable residual value.<\/strong> We look in more detail at how the remaining capacity specifically affects valuation and purchase price in our <strong><a href=\"https:\/\/over-the-air.de\/en\/state-of-health\/ev-battery-remaining-capacity\/\">article on battery remaining capacity<\/a><\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">Added to this is the warranty relevance: with many manufacturer warranties, the SoH must not fall below a threshold of around 70 percent. (<a href=\"https:\/\/autogazette.de\/elektroauto\/soh\/gebrauchtwagen\/gebrauchtes-e-auto-batterie-zertifikat-zu-empfehlen-989430243.html\" target=\"_blank\" rel=\"noopener\">Source: Autogazette<\/a>) A documented value therefore also shows how much warranty buffer a vehicle still has \u2013 a practical argument both when buying and when selling.<\/p>\n\n<h3 id=\"vertrauen-und-haftung\" class=\"wp-block-heading\">Trust and liability<\/h3>\n\n<p class=\"wp-block-paragraph\">Buyers reward transparency. <strong>According to the DAT Report 2025, around 44 percent of used car buyers would like a battery certificate<\/strong> to safeguard their purchase decision. (<a href=\"https:\/\/www.dat.de\/news\/gebrauchte-e-fahrzeuge-nischenprodukt-mit-potenzial\/\" target=\"_blank\" rel=\"noopener\">Source: DAT<\/a>) The portal mobile.de now requires an existing certificate to be uploaded if it is used in advertising. (<a href=\"https:\/\/www.heise.de\/news\/Batteriezertifikate-fuer-Elektroautos-Manchmal-nun-Pflicht-bei-mobile-de-11072672.html\" target=\"_blank\" rel=\"noopener\">Source: heise<\/a>) For the trade, proof specifically means: fewer discussions in the sales conversation, cleaner documentation for the buyer and a lower risk of later complaints about the battery.<\/p>\n\n<h2 id=\"welche-methoden-es-gibt-ein-vergleich\" class=\"wp-block-heading\">Which methods are available \u2013 a comparison<\/h2>\n\n<p class=\"wp-block-paragraph\">Today there are essentially three ways to obtain a battery certificate for an electric car. They differ significantly in effort, duration and suitability for everyday trading. <\/p>\n\n<h3 id=\"physischer-test-am-fahrzeug\" class=\"wp-block-heading\">Physical test on the vehicle<\/h3>\n\n<p class=\"wp-block-paragraph\">In the classic method, the vehicle is connected to a <strong>diagnostic device via the OBD interface<\/strong>. In the detailed variant, the battery is discharged over several days from full to around ten percent without recharging in between; the certificate is then available after one to two working days. There are now also <strong>significantly faster<\/strong> variants that determine the condition in a few minutes via plug-and-play. What all physical methods have in common: a device must be connected to the vehicle on site.   <\/p>\n\n<p class=\"wp-block-paragraph\">There is a <strong>trade-off<\/strong> between the two variants: the discharge drive is considered particularly thorough because it captures the real charging and discharging behaviour of the battery \u2013 but it requires a separate device per vehicle and a collection period of several days of normal use until the certificate is available. For a single, high-value vehicle, this effort can be worthwhile. <strong>For a larger stock or a fleet, it hardly scales:<\/strong> a hundred vehicles mean a hundred devices, a hundred collection periods \u2013 and no overview of the entire stock at a glance. <\/p>\n\n<h3 id=\"hersteller-daten-per-fin-over-the-air\" class=\"wp-block-heading\">Manufacturer data via VIN (over-the-air)<\/h3>\n\n<p class=\"wp-block-paragraph\">A second method uses the data that the vehicle manufacturer records anyway. The SoH value is retrieved via <strong>the VIN directly from the manufacturer\u2019s systems<\/strong> \u2013 without a diagnostic device, without a discharge drive and without the vehicle being taken out of service. The value is available <strong>immediately<\/strong>.  <\/p>\n\n<p class=\"wp-block-paragraph\">An important distinction is worthwhile here: the result is a <strong>report<\/strong> of the values transmitted by the battery management system (BMS) and determined by the manufacturer \u2013 not a measurement of the provider\u2019s own. This must be distinguished from the <strong>formally certified<\/strong> battery test result (for example according to the CARA standard), which constitutes recognised proof. A fast VIN report and a formal certificate are therefore not the same, but two complementary levels.  <\/p>\n\n<h3 id=\"selbstauslesen-per-obd-adapter\" class=\"wp-block-heading\">Self-reading via OBD adapter<\/h3>\n\n<p class=\"wp-block-paragraph\">With an OBD2 adapter and a suitable app, an approximate SoH value can sometimes be read out yourself. This is inexpensive, but does not provide a standardised, signed certificate and its reliability varies depending on the model and app \u2013 it is therefore only of limited suitability for a reliable valuation in the trade. <\/p>\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th>Method<\/th><th>Device \/ effort<\/th><th>Time to result<\/th><th>Vehicle blocked?<\/th><th>Suitability for trade \/ fleet<\/th><\/tr><\/thead><tbody><tr><td>Physical test (on the vehicle)<\/td><td>Diagnostic device via OBD, on site<\/td><td>a few minutes to several days (depending on variant)<\/td><td>Device must be connected<\/td><td>good for individual vehicles, more effort for stock<\/td><\/tr><tr><td>Manufacturer data via VIN (OTA)<\/td><td>none, only VIN<\/td><td>immediately<\/td><td>no<\/td><td>suitable for individual vehicles and entire stock<\/td><\/tr><tr><td>Self-reading via OBD<\/td><td>OBD2 adapter + app<\/td><td>a few minutes<\/td><td>no<\/td><td>only rough self-assessment, no certificate<\/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\">Regardless of the method: a single SoH value is only truly meaningful in relation to age, mileage and comparable vehicles \u2013 the right classification is decisive.<\/p>\n<\/blockquote>\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<figure class=\"wp-block-image is-resized has-custom-border\"><img decoding=\"async\" src=\"https:\/\/over-the-air.de\/wp-content\/uploads\/2026\/10\/tim-hochgreef-author-website.webp\" alt=\"Tim Hochgreef, Managing Director autoDATAexperts\" style=\"border-radius:50%;aspect-ratio:1;object-fit:cover;width:72px;height:72px\"\/><\/figure>\n\n\n\n<p class=\"wp-container-content-9cfa9a5a wp-block-paragraph\" style=\"font-size:16px;line-height:1.5\">We are the experts for innovative battery solutions in the EV market.

This is exactly where <a href=\"https:\/\/autodataexperts.de\/over-the-air\" target=\"_blank\" rel=\"noopener\">SoH OTA from autoDATAexperts<\/a> comes in: via the VIN, the battery condition is retrieved directly from the manufacturer\u2019s systems \u2013 without a diagnostic device, without a discharge drive, without a workshop visit. An employee enters the VIN and receives the SoH value as a battery check report; billing is per query. For formally recognised proof, autoDATAexperts, as a <strong>member of the CARA Europe association<\/strong>, also offers <strong>fully CARA-certified battery tests<\/strong>. In this way, the fast report for the current stock can be combined with the certified test for particularly valuable vehicles.

(<a href=\"https:\/\/www.bundesumweltministerium.de\/themen\/kreislaufwirtschaft\/abfallarten-und-abfallstroeme\/altbatterien\/europaeische-batterieverordnung-eu-2023\/1542\" target=\"_blank\" rel=\"noopener\">Source: Federal Environment Ministry<\/a>) Important for differentiation: the battery passport is a regulatory obligation, primarily on the manufacturer side, covering the entire life cycle. Today\u2019s battery certificate, on the other hand, is a voluntary, point-in-time proof of the current condition that dealers can already use now. Anyone who already incorporates the documented battery condition into their processes today is prepared for the upcoming requirements instead of being surprised by them.  <\/p>\n\n<h2 id=\"fazit\" class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p class=\"wp-block-paragraph\">A battery certificate for the electric car makes the <strong>decisive value driver of an EV<\/strong> visible \u2013 and thus creates certainty when buying, trust when selling and a reliable residual value.

We are happy to discuss in a direct conversation how this can be integrated into your processes without diagnostic devices and downtime.  <\/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-1781174591159\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is a battery certificate for an electric car?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A battery certificate documents the health (State of Health, SoH) of the traction battery as a percentage of the original capacity. It usually contains the VIN, the test date and the measurement method and is usually issued as a digitally signed PDF. The condition of the battery is assessed as a system. For the trade, it is proof that makes the value and condition of a used electric car verifiable.   <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1781179160602\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong><strong>Is a battery certificate mandatory when selling a used car?<\/strong><\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>No, there is currently no general certification requirement. However, individual platforms require an existing certificate to be uploaded if it is used in advertising.
