LITHIUM-ION BATTERIES
store part of the extra energy produced by the fuel cell as well as kinetic energy recovered during braking . The batteries supply the train under normal operation and can be used to boost the acceleration of the train when necessary .
|
THE AUXILIARY CONVERTER
converts electrical energy received from the fuel cell or the battery to adapt it to the various on-board equipment ( air conditioning , doors , passenger information displays , lighting …)
|
THE TRACTION INVERTER / CONVERTER
ensures that the appropriate energy is transmitted between the fuel cell , the battery and the traction motor . It also collects energy generated by the movement of the train during braking , redistributing it to the auxiliary converter and the batteries .
|
THE TRACTION MOTOR
drives the wheels for acceleration and braking .
