Opportunity charging consists of using short stops of the vehicle to partially charge the battery. The charging technology can be with or without contact, overhead, lateral or ground-based.
Depending on the itinerary, the distance between stops and their duration, the charging stations are positioned to optimise the load and investment cost.
They can be located in terminals, stations, toll plazas, taxi stands, etc.
This solution is particularly well suited to buses: the itineraries are known and cyclical.
