Patrick Schr\u00f6der has nearly 20 years of hands-on experience in the automotive industry \u2013 from vehicle trading to international remarketing. Today, his main focus is on how new technologies can make the automotive trade more efficient, more transparent and fit for the future.<\/p><\/div><\/div>\n\n\n

Anyone in the trade who values a used electric car has to check the battery health of the electric car before a reliable purchase price can be set. The traction battery accounts for a considerable share of the vehicle’s value \u2013 and unlike with a combustion engine, the mileage reveals very little about its actual condition. For dealers, fleet operators and rental companies, the question is therefore not academic but directly relevant to decisions: how healthy is the battery, and which method delivers a reliable answer quickly? This guide compares the common methods \u2013 from the classic EV battery test to over-the-air retrieval \u2013, explains the central SoH value and shows which method suits which situation. <\/p>\n\n\n\n
