The maximum charge rate may crucially depend on the mode of operation of the electrochemical energy store device, and therefore a distinction should be made in particular as to whether energy is being supplied to or withdrawn from said device. The electrochemical energy store device can heat up during charging or discharging processes, and therefore in particular the duration of the energy withdrawal and/or energy supply can influence the level of the current intensity which can be withdrawn and/or which can be supplied. The current intensity which can be withdrawn and/or supplied depends in particular upon the state of charge of the electrochemical energy store unit and is therefore controlled in particular on the basis of said state of charge. When in a critical temperature range, the electrochemical energy store cell is particularly difficult to control. Therefore, the current intensity which can be withdrawn or supplied is set to zero when a maximum temperature is reached and/or a minimum temperature is reached. | 03-14-2013 |
