Scania is a world-leading provider of transport solutions. Together with our partners and customers we are driving the shift towards a sustainable transport system. In 2017, we delivered 82 500 trucks, 8 300 buses as well as 8 500 industrial and marine engines to our customers. Net sales totalled nearly SEK 120 billion, of which about 20 percent were services-related. Founded in 1891, Scania now operates in more than 100 countries and employs some 49 000 people. Research and development are concentrated in Sweden, with branches in Brazil and India. Production takes place in Europe, Latin America and Asia, with regional production centres in Africa, Asia and Eurasia. Scania is part of Traton Group. For more information visit www.scania.com.
Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.
Electric vehicle industry is growing exponentially, and today, any vehicle company that wants to stay in the competitive market has to expand in electric vehicle area. The challenges become many times greater when electric vehicle systems are applied to semi & heavy-duty truck vehicles. The main challenges are the high-power source that is needed to supply the vehicle; and also, the high voltage components that needs to withstand tougher environmental challenges.
With these factors in mind, the costs for construction of electric vehicles becomes very high. Therefore, a competitive company has to minimize the cost of design & construction if possible. To study this possibility, different types of optimizations are required. This project aims to optimize the required high voltage cable dimension that is utilized in the high voltage electric system of the Scania trucks.
Many truck vehicle companies are investing heavily in the electric vehicle (EV) development, and Scania is no exception. However, the cost of material & development of an EV truck is very high and therefore Scania always try to achieve more profitable solutions. The minimization of cost will directly influence the selling price of the truck – and by lowering the selling price, the EV becomes more attractive to the costumer.
However, the minimization of cost does not mean to lower the quality of the product, but rather to design a more profitable product. One possible way to minimize the cost of materials of EV systems is to study the electrical connection of the system. To do this, a study is needed regarding all the HV components included in a complete HV system – one way can be to map the current Hybrid system in a Scania vehicle. The mapping of HV connection is needed to be able to study the risks of fault currents that can occur in the HV system.
This project basically aims to define the crucial dependent factors that are required to be able to choose an optimized dimension of HV cables utilized in a vehicle’s HV system. The idea is that this study will conclude some type of guidelines to how to design a HV system that is optimized to the needs of operation, at the same time the optimization of the system should not introduce any type of risks that will endanger the components utilized or to basically fail the system requirements.
The assignment is to identify the main factors that should be taken into account while designing the electrical connection of HV electric vehicle systems. A literature study should be done to have some kind of knowledge of the current situation – this literature study can for instance include the HV electric system in automobile industry. The project will, if needed, include the opportunity to introduce different tests needed for the HV component and the connections of those. The applicant will of course have the opportunity to use the results of these tests to certify the made study.
The applicant is expected to present the study in a technical report that explains in detail the made study and the final conclusions.
