The energy management of the vehicles within the system is essential in relation to its sustainability, performance and availibity. The electrically driven vehicles are energy efficient and emission free at the point of operation. The on-board energy system is tailored to the application requirements, including the demand pattern, the energy required to complete the single longest trip, and the power required for secondary systems such as heating and airconditioning. This ensures the infrastructure can remain basic and affordable, while also saving Co2 and NOx emissions.
Power consumption and range
2getthere’s vehicles are designed for both cold and (extremely) warm climates. Especially airconditioning and cooling of components demand significant energy. In normal operating conditions the GRT vehicle provides a range exceeding 50 kilometers. The power is converted to 24V for the vehicle control system and its sensors, while the drive train and air-conditioning directly powered from 400V for efficiency. Charging at 4.5 times the capacity only 11 minutes are required from 30% to 80% state of charge, ensuring a 90% availability relative to 50% for the competition.
‘No-plug’ and play
Charging of the vehicles is fully automatic, not requiring the vehicle to be plugged in manually or the operator to provide any order. Vehicles take themself out of service based on their state of charge. With charge pads integrated into the road surface at the station berths no time is lost moving to/from charging. Once the vehicle is over the charge pads, it lowers it pads to commence charging. The vehicle’s Battery Management System monitors the state of charge, cell voltage, battery temperature and charging during the process.
