• Number of environmentally friendly (carbon-proofed) cross-border transport initiatives developed; Value – [4].

Project results / Indicator ofachievement:

• Improved automation system for auxiliary loads of the electric bus.

Besides the main loads as electric traction motors, the auxiliary loads (lights, heating/cooling systems, etc.) are also very important components within the electric bus functionality. From the energy efficiency point of view, it is very important that these loads have to work properly and integrated within main power supply system.

In this context, it is proposed that these auxiliary loads will be controlled by an improved automation system based on Programmable Logic Controllers (PLC) in order to optimize their own energy consumption.

Value – 1.

• Advanced thermal model related to the climatic environment within the electric bus.

From the point of view related to the public transportation, another important aspect is the indoor climatic environment where actually, the passengers have to spent some more or less time during their travel to the destination.

In this case, it is proposed an advanced thermal model based on finite element method in order to analyze the influence of the heating/cooling system from the electric bus on the general climatic environment. The model will predict the optimal inside temperature depending on outdoor thermal influences.

Value – 1.

Contribution to programme output 1

There are 4 numbers of environmentally friendly (carbon-proofed) cross-border transport initiatives developed:

1. Optimization of electric energy consumption: an improved automation system for auxiliary loads of the electric bus will lead to the increasing of the energy efficiency of the auxiliary loads through the integration within main power supply system and optimization of their power consumption.
2. Increasing of power efficiency: The increased power efficiency at this level will have an important impact on general power consumption and finally to the environment because of low carbon footprint.
3. Decreasing of the thermal losses: Also, the new advanced thermal model to be used for thermal analysis of the indoor climatic system with the aim to improve the quality of life of the passengers, will generate important effects through thermal optimization of the inside environment and finally, because of the decreasing of the thermal losses, this will contribute as a new environment friendly initiative.
4. Theoretical solution for using the renewable energy as an ecological solution for recharging the batteries of the electric bus from a system with photovoltaic panel.
