The linear motor enables energy transmission into the vehicle without catenary or contact rail. In order to ensure constant energy supply to the on-board power system even in the event of serious fluctuations of current, a battery in combination with high-power electric double-layer capacitors is used as an energy buffer. If necessary, the energy-supply module feeds energy into the on-board power system and will later be recharged by the linear motor. The double-layer capacitors absorb the peak powers occurring in the process while the battery is operated in the base load range. Control of the energy-supply module therefore requires an intelligent energy management whose information processing is closely linked to the current-control devices of the motor.
