 Opportunity Charging is Ultra Fast charging at the turn-around location of the bus route. Without the need of schedule change, electric buses can run all day and a significant passenger capacity increase and cost reduction can be achieved.

Heliox Power Curve Technology results in ultrashort charge sessions, that reduce the impact on the timetable to a minimum: within 2-5 minutes of opportunity charging at the end bus stops, you can optimize your electric bus operation. Implementation is simple and straightforward; the solution is fully scalable and can be introduced route by route. This charger has the elements required for V2G and smart grid functionality.
