Tiivistelmä
This study analyses the data of electrical energy consumption of eBuses provided from Smart Tampere. The data was collected from 4 eBuses operating in Tampere, Finland during 2017-2018. The importance of electrical energy consumption data collection comes from ne-cessity of understanding the behavior of eBuses in a mid-sized city and comparison of ad-vantages of those to diesel buses.
This work provides the results calculated from provided data and gives the example of ne-cessity and implementation of those for cash flow calculations. The results include, the aver-age electrical energy consumptions of eBuses per hour, per day, per month, per season and per kilometer. The implementation of calculated electrical energy consumption of eBuses per kilometer was applied to previous studies of feasibility of electric buses in public transport to compare calculations with estimated values to those closer to real-time based results.
The results showed the importance of the accuracy of electrical energy data collection, the necessity of future developments in data collection and the effect of accuracy change on cash flow calculations. The results from calculations of cash flows showed, that even the slight change in accuracy of energy consumption results might move the break event point between diesel buses and eBuses up to 1 year further or backwards. The average values of electrical energy consumption calculated in this work appeared to be different from the same values es-timated in previous researches up to 0.4 kWh/km. The ways to improve further electrical en-ergy consumption calculations were introduced and explained.
