2.2 BEV Consumption on countryside roads (class 1 and 2 roads) The data come from 5 return trips on a selected route in Eastern Bohemia. The route includes 18 km of high-speed roads (110 kph), 5 km of driving through a city using a ring road, 14 km of class 1 roads and 30 km of class 2 roads. The goal was to drive at a maximum allowed speed throughout the entire trip. The incline degree of the entire route is 506m.

The data come from 11 trips (11 x 86 km) in the city of Pardubice driven during business days. Pardubice is located on flat land. The route was copying the route of a number 7 trolleybus, including morning and evening peaks. Due to traffic circumstances, the vehicle spent 30% of the time in traffic jams. That’s why the data records show an obviously increased share of HVAC and 12 V system consumption.
