Introducing elektric buses to the Prague transportation system

Future mobility

the Prague Public Transit Company tests various technical solutions for charging electric buses under the standard Prague traffic conditions.

Static charging - parked vehicles

  • Since September 2015, 1 electric bus with fully electric operation, including heating and air-conditioning, has been operating on lines 213 (Želivského – Nádraží Uhříněves) and 163 (Želivského – Sídliště Rohožník). Charging of the electric bus is conducted as a combination of night charging in the garage using a cable and charging during operational breaks at the Želivského bus turn station via a pantograph collector and the two-pole trolley lines.  Electric energy is collected from the tram power network, which allows for achieving the optimal price per kWh.
  • A total of 14 electric buses with fully electric operation, including heating and air-conditioning, will operate on line 207 (Staroměstská – Ohrada) at the second half of 2018. Charging of the electric bus will be conducted as a combination of night charging in the garage and charging during operational breaks at the Ohrada bus turn station, in both cases via a pantograph collector and the two-pole trolley lines.  Electric energy will be collected from the tram power network, which allows for achieving the optimal price per kWh.

Dynamic charging - moving vehicles

  • 1 vehicle with dynamic charging and with fully electric operation, including heating and air-conditioning, will operate on line 140 (Palmovka – Miškovice, during the first stage at the Palmovka - Letňany section) at the end of this year. Charging of the electric bus is conducted as a combination of charging while the bus is moving via collectors of the trolleybus type and static charging in the garage using a cable at the Palmovka bus turn (90% batteries and 10% under the trolley). The trolley for dynamic charging will be installed at Prosecká Street between the Kundratka and Kelerka stops with the objective to test electric bus advantages and possibilities of continuous battery charging while the bus is moving up the steepest hills (which represents the most demanding movement from the energy consumption perspective). Electric energy will be collected at the Palmovka node from the tram power network (Dobudka), which allows for achieving the optimal price per kWh. A mobile container exchange station, which will be attached to the 22 kV network, will be installed at Prosecká Street.

Benefit

  • Reduction of the production of harmful emissions created during diesel engine operation
  • Noise reduction on the streets
  • Utilization of synergy effects within the frame of DPP (using the existing power supply infrastructure of trams, utilization of the compounded energy purchases)
  • Bus transportation modernization
