Hybrid Energy Systems for Vehicle Industry
Published in Yatish T. Shah, Hybrid Energy Systems, 2021
A few pilot projects have also been built in the framework of the “Heliotram” project, such as the tram depots in Hannover Leinhausen and Geneva (Bachet-de-Pesay). The 150 kWp Geneva site injected 600 V DC directly into the tram/trolleybus electricity network provided about 1% of the electricity used by the Geneva transport network at its opening in 1999. On December 16, 2017, a fully solar-powered train was launched in New South Wales, Australia. The train is powered using onboard solar panels and onboard rechargeable batteries. It holds a capacity for 100 seated passengers for a 3 km journey. Recently, Imperial College London and the environmental charity 10:10 have announced the renewable traction power project to investigate using track-side solar panels to power trains. Meanwhile, Indian railways announced their intention to use onboard PV to run air-conditioning systems in railway coaches. Also, Indian Railways announced that it is to conduct a trial run by the end of May 2016. It hopes that an average of 90,800 L of diesel per train will be saved on an annual basis, which in turn results in reduction of 239 tons of CO2 [5,113–120].

The invention by Dearborn [18] provides a means by which rail (railroad) transportation operators can generate megawatts of carbon-free electrical power from the space over rail tracks and right-of-way without buying or leasing significant amounts of sun accessible space or power transmission right of way.

The technology allows for road electrification started long ago with the electrically powered public transportation vehicles that still commonly seen in some cities. In recent decades, active explorations over new ways of dynamic charging enabled directly from roadway have been found, aiming to power electrically propelled vehicles of different types and in different urban and highway scenario conditions. Depending on the specific power transfer technology, the major eRoad systems can be categorised into the following three types: Wireless solution using Inductive Power Transfer (IPT) technology (Figure 1 a): A typical IPT system consists of an off-board power delivery device embedded in the roadway and an on-board receiver device mounted under the vehicle's chassis. Being a near-field wireless power transfer technology, the IPT technology can inductively deliver electricity to a receiver device with high power but limited air gap distance. An extensive summary of the working principle and geometry design of the IPT system, as well as its roadway embedment means, can be traced elsewhere (Chen et al.2015).Conductive solution with a conductive rail (Figure 1 b). The electric power, supplied from the rails located in the slot of a conduit that mounted on roadway surface, is transferred to the battery charger of the vehicle via a movable arm and finally reaches the electric motor either directly or through the battery. This unique way of dynamic charging can be adjusted according to vehicle types and has been under active testing by ELWAYS in Sweden (ELWAYS 2019).Conductive solution using Pantograph (Figure 1 c). The Pantograph installed on top of truck head transmits power from the overhead contact lines to the electric motor of a vehicle. The Pantograph can be easily connected and disconnected to the contact wire that in connection with the catenary system embedded at the roadside, which is very similar to a trolleybus. This way of dynamic charging is particularly suitable for heavy duty vehicles with a fixed route.
