| 摘要 |
The invention relates to a system for storing electric energy, comprising a first and a second storage cell, each storage cell having an operating voltage, and a device is provided for reducing the energy content of a storage cell when a threshold voltage is exceeded or reached. The invention is characterized in that a control device which is designed to detect a parameter of the first and/or second storage cell, to identify a state of deterioration of the storage cell, and to change the threshold voltage of the first and/or the second storage cell is provided.
