Abstract
Various embodiments include a method for ascertaining the residual value of a used battery. The method may include: feeding the battery to a test station; bringing it to a test temperature; stabilizing the temperature within less than 2 K; measuring a load cycles using a high-precision coulometry apparatus; carrying out measurement until fulfilment of a termination criterion; ascertaining a first and a second value for a discharging capacity using two different calculation rules, wherein calibration is handled differently in the two calculation rules; carrying out an optimization process; determining a residual value of the battery; and determining whether the used battery is to be employed for use in a static energy storage device.
