A study on the feasibility of the new concept of fully electric bus and its charging operations, considering 2 approaches: fast opportunity charging on-street and without opportunity charging, both are in part within ZeEUS project.
ZeEUS, the Zero Emission Urban Bus System, aims to be the main EU activity to extend the fully-electric solution to the core part of the urban bus network. It fits within the context of the European Commission’s objective to create a competitive, clean and sustainable transport system.
Set in Barcelona, this study focuses on analysing and evaluating suitable routes to be electrically performed. At the same time, it is required to check profitability trying to compare different operative models of recharge, considering both approaches: fast opportunity charging on-street and without opportunity charging (autonomous vehicles).
From these two different models, the objective is to compare both its benefits and drawbacks in terms of operation, efficiency and economy. Linked with economic aspects a feasibility study will be reported to analyse its electro mobility model. It will be used for further actions to determine whether or not electric bus deployment is feasible.
Therefore, we will present a summary of our experience taken day by day with 2 different types of fully electric buses that run in Barcelona:
- Opportunity charging vehicles: 2 SOLARIS buses of 18m (received in December 2015).
- Autonomous vehicles: 1 BYD and 2 IRIZAR buses of 12m.
The main daily information taken are: kilometres, hours in service, SOC (State Of Charge) of the battery, consumptions (kWh/100km), breakdowns, temperature, and number of validations.
With this information we will present KPI’s (Key Performance Indicators) crossing different data to measure the impact in the operation of the different electric buses: reliability, hours (driver shift) by type of bus, consumption related to the orography, etc.
Through an impact assessment on electric buses, TMB will measure their Life Cycle Cost, comparing a full electric bus with a classical diesel one.
Finally, the underlying objective of this Case Study is to improve air quality (reducing local and global emissions) by deploying electromobility in the city of Barcelona.
