E-buses Charging Infrastructure

Charging Infrastructure for Electric Buses for a zero emissions public transport.

For cities going through a new way of travel towards a cleaner future.


As the mobility sector continues to request new solutions for a sustainable and efficient private transport, cities are testing public transport electrification as well.
Using electrified means of transport means less energy consumption, less noise, less CO₂ emissions, lower lifecycle costs, and reliable service.

FRIEM is a partner of choice for those who want to retain full control on their infrastructure and investments independently from the electricity supply sources and of the vehicles they use.

FRIEM product portfolio for electric bus charging allows the depot infrastructure to follow increasing penetration of electric buses within the operator fleet while minimizing the operational costs of the bus Operator.

Electric buses can be recharged in two different ways: via CCS connector connected to a dispenser or via a pantograph connection to a charging device located on a pylon, called the Opportunity Charger. This charging device allows a high-power energy transfer (>150 kW) and is widely used for bus charging along the line or at the terminus. In this way you can use buses with smaller batteries, but they can be recharged during the exercise.

Components of the FRIEM’s bus charging infrastructure are:

  • Distribution MV/LV cabin (“Cabinet”);
  • AC/DC Rectfier;
  • Power cabinets;
  • Dispensers, which can be of two types:
    • DC charging dispenser with CCS standard;
    • Opportunity Charger DC to pantograph
