Khan's Electric Transport For London: You Can Be A Lobster In Summer And A Frozen Prawn In Winter. The World Is Your Oyster Card.
Just like for electric vehicles, a very large issue with electric buses is the mileage range limitation. As stated in a technology assessment of an electric bus system for Berlin, the energy consumption per Kilometre can grow up to 56 % in electric buses due to the HVAC system, in extreme external temperature conditions (e.g. from 2,3 kWh/km to 3,6 kWh/km, with an external temperature of -17°C) (3). This high percentage value shows how inefficient current HVAC solutions are in electric buses. By optimising the HVAC system, it would be possible to utilise the energy saved to increase the mileage range.
Should not surprise anyone, yet it does.
Looks like sweaty cabbies have joined the EV revolution and found new levels of stinginess. 😀
