The electrically driven vehicles are energy efficient and emission free at the point of operation. The on-board energy system is one of the focus points during the application engineering, being 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 air-conditioning. This ensures the infrastructure can remain basic and affordable, while also saving Co2 and NOx emissions.
The 3rd generation GRT default configuration is two Li-ion nano NMC (Lithium-nickel-manganese-cobalt) batteries. The battery provides a range exceeding 50 kilometers, operating normally between -15˚C and 55˚C using water-cooling. The battery is charged from the wall, with charging pads embedded in the floor. The power delivered by the 92 Ah/400 Vdc Li-ion nano NMC battery pack is converted to 24V for the vehicle control system and its sensors, while the high power drive train and air-conditioning are directly powered from 400V for efficiency.
The 2nd generation PRT vehicle is equipped with sophisticated LiFePO4 batteries by default, as it has the ability to withstand high temperatures without decomposing. The batteries have a maximum range of 75 kilometer in normal operating conditions, being able to handle temperatures between -20˚C up to 50˚C without cooling being required. The vehicle features an onboard charger, which transfers the power from 80VDC to 60VDC. The Battery Management System monitors the State of Charge, Cell Voltage, Battery temperature and charging.
