A process for determining the state of a battery by carrying out in a cycle, starting from a specific charging state of the battery, a charging operation and a discharging operation, each with a specific current, the cycle being terminated when the specific charging state is reached again, and the state of the battery being deduced from the difference between the time periods required for the charging operation and the discharging operation. Alternatively, from a specific charging state of the battery a discharge can be carried out, in order to determine the available capacity from the extracted charge.
