System for operating electrical traction components charges capacitor from battery and returns stored energy to battery depending on capacitor state of charge, characteristic parameter

摘要

The system has at least one battery (9) and at least one high power capacitor (11). Charging the capacitor from the battery and the return of stored energy to the battery from the capacitor is carried out depending on the state of charge of the capacitor and on at least one characteristic parameter representing the existing energy availability or demand of the electrical machine (3,6).
