Energy Storage System
First Claim
1. An energy storage system for an at least partially electromotively drivable motor vehicle having a drive unit constructed as an electric machine for generating a drive force on a drive train, the energy storage system supplying energy to the electric machine, comprising:
- a first energy storage unit comprising capacitive energy storage devices;
a second energy storage unit comprising electrochemical energy storage devices, the second energy storage unit being coupled in parallel with the first energy storage unit; and
a control system operatively configured such that the energy supply to the electric machine takes place during motive operation of the electric machine by way of the first energy storage unit while, as required, a recharging of the first energy storage unit takes place via the second energy storage unit.
