Electric-hybrid buses and trams which also run on batteries solve the range problem in local traffic and perform convincingly in urban transport networks thanks to their environmental friendliness. But they all still need to refuel or re-charge. Particularly efficient systems are those that automatically detect when a charging station is nearby. Still - how do public transport vehicles actually maintain a dialogue with their charging stations?
An electric bus approaches a charging station. The transponder at an electrical power supply station announces: "I offer external power". The electric bus gladly accepts the offer, so it can charge up and be ready to make more trips. This communication works via UHF RFID readers via the antenna of the electric bus and transponders at the fixed power stations. The RFID system interacts directly with the power control of the electric bus. The charging device is activated even before the electric bus comes to a complete halt at the charging station. This means that the electric bus can immediately start charging once it comes to a halt - and makes the electromobile use of mass transit systems highly efficient.
The drivers don't need to keep an eye on the charge level on buses and trams. It takes place fully automatically.
- e-mobility in local public transport with on-demand charging
- Integrated industrial functions, e.g. automated identification of objects, combined with external sensors
For future decision-makers of e-mobility in local public transportation
- Suitable for cities that cannot permanently supply public transport with electric power
- Environmentally friendly, flexible, cost-efficient
