Focus on electric Postbuses
Local, emission-free transport with electricity from Switzerland

Rich Content Section

Our current focus is on electric Postbuses with electric battery drive systems. This technology is the most advanced, it has proven itself in practice in Switzerland and abroad, and battery-powered buses are already available on the market in a wide variety of models from many different manufacturers.

However, battery-powered buses are not yet suitable for all topographies, either because their range is not sufficient or because the strain on the battery and drive system would be too great. For this reason, PostBus has made a conscious decision to remain open in its choice of new technology, while closely following the development of fuel cell technologies and synthetic fuels.

How a battery-powered bus works

Battery-powered buses have electric motors that obtain their drive energy exclusively from a battery. The battery is recharged once or several times a day via the electricity grid. At present, the average range of battery-powered buses on a single charge per day is around 250 kilometres. The range can be increased to over 300 kilometres or more if the battery is recharged several times a day. This occasional charging is done either in short intervals with high power at the terminal stops or during breaks in the depot throughout the day – for example, at lunchtime.

All PostBus battery-powered buses obtain 100 percent of their electricity from renewable energy sources in Switzerland.

Battery technology and the range of battery-powered bus models are developing very quickly. In the next few years, a significant boost to battery capacity is expected, with a corresponding increase in the range and economic viability of battery-powered buses.

How we charge Postbus batteries

PostBus has different charging systems in place for battery-powered vehicles:

  • Depot chargers: the Postbus battery is recharged once a day – usually overnight.
  • Occasional charging: recharging during sufficiently long stops while on the road, at a terminal stop or in the depot. This kind of top-up charging is currently done using a plug or pantograph that is lowered onto the vehicle from above.
