Ayvens Carmarket, a leading remarketing platform for professional car traders and dealers, is introducing State of Health (SoH) certificates for its used battery electric vehicles (BEVs) in Europe. Since the battery is the most valuable part of an EV, its condition plays a key role in determining the vehicles resale value. The SoH certificate shows the battery’s current capacity as a percentage of its original capacity. It offers transparent and reliable information about a battery’s health, along with determining actual driving range. This helps build trust and confidence in used EVs.
Ayvens Carmarket’s battery diagnostics are provided through accredited companies, certified by the European Car Remarketing Association (CARA). These diagnostics rely on reading the SoH value directly from the Battery Management System (BMS) which continuously monitors key parameters such as voltage, temperature, charging history and current usable capacity to accurately determine the battery SoH. To date, SoH certificates are available for used electric vehicles on sale in Ayvens Carmarket’s used car showrooms and websites in the Czech Republic, Finland, France, Germany, Portugal, and the Netherlands. SoH certification will be rolled out in most of the remaining European countries in the coming months.
Despite initial concerns about battery longevity, data shows that modern EV batteries hold up better than expected . But the market still suffers from misconceptions, mainly due to the lack of transparency around battery health, which represents one of the main barriers to EV adoption.
