State of Health

A customer buys a used electric car, drives through the first winter and gets in touch: the range is much lower than expected, and he wants to withdraw from the purchase. For dealers, this is the core question of the electric car battery warranty: is declining battery capacity a material defect – and who has

With electric car lease returns, the battery decides how quickly and at what price the vehicle finds a second user. In 2026, a wave of young used EVs is coming back from leasing contracts – significantly more vehicles than the trade has been used to. At the same time, buyers are hesitant: according to a

Two structurally identical electric vehicles, same year of registration, almost identical mileage – and yet their residual capacities are several percentage points apart. When buying in, this is not a detail but a four-figure sum. Battery condition assessment for electric vehicles therefore replaces estimation with a measurable figure: the State of Health (SoH).

When it comes to a used electric car, a single component determines value and risk: the traction battery. It is the most expensive element of the vehicle – and the biggest uncertainty factor for buyers. A battery certificate for the electric car creates clarity here by documenting the health of the battery. For dealerships, fleet

When buying a used electric car, a single value often decides between profit and miscalculation: the remaining capacity of the electric car battery. It shows how much of the original storage capacity is left – and thus directly influences range, resale value and purchase price. For dealerships and fleet managers, it is therefore not a

The SoH battery assessment has evolved from a side issue into a key metric in the used electric vehicle trade. While mileage and year of manufacture dominate the valuation of combustion cars, it is above all the condition of the high-voltage battery that determines an electric car’s range, residual value and saleability. SoH is the
