The citizens of Barcelona, a city at the cutting edge of sustainable public transport solutions, are witnessing a new milestone in efficiency and electric mobility. The H16 line has the first ultra-fast charging point using a pantograph for electric buses installed in Spain one of the first in Europe.
This initiative, implemented by Endesa working with TMB (Transports Metropolitans de Barcelona), is part of the project to promote electric mobility in the city Zero Emission Urban Bus System (ZeEUS), funded by the European Union and involving a total of ten European cities.
Ultra-fast charging using a pantograph is carried out using two elements: the charger, a pillar approximately five metres high, similar to a lamp post that has been installed at the end of the line to make the most of the stopping time and not interfere with route times; and on the other hand, the pantograph, a type of retractable mechanical arm on the bus roof that folds out and connects to the charger to start charging.
For effective and fast recharging of the electric battery, two key points have been installed in the bus infrastructure: the proximity sensor on the front that warns the system when the vehicle is approaching the charging point; the position sensor, on the back of the bus that prepares the pantograph arm to connect to the pillar hood and start charging.
The ultrafast charger restores up to 80% of the battery in an estimated time of between five and eight minutes. The charge is sufficient for the bus to set off on its route again, since it can normally be driven with the battery between 40% and 80%. This is possible thanks to the 400 kW of power in the charger.
