Inductive charging of heavy Battery Electric Vehicle

Important results from the project

The project aims to develop a platform to evaluate inductive charging as a technology. This is seen as a step and an important component in the development of the infrastructure for charging and associated interfaces. Different customers have different conditions and eligibility requirements and we want to explore a wider range of charging options. We also see great opportunities to optimize the range and battery size of the vehicles with the help of strategically placed charging plates.

Expected long term effects

The technology has been evaluated against existing charging alternatives such as pantograph and CCS charging via cable. The comparisons have been carried out against EMC eligibility requirements, efficiency measurements and technical characteristics, weather resistance, cooling concept, etc. We have gained increased knowledge about how this technology stands up to the other concepts today and how to implement such an installation. The result shows that all properties are met except for the cooling capacity, which is not optimized for our prototype bus.

Approach and implementation

Phase 1 Development and implementation of software. Plan and implement safety functions, locate test area on Scania and create test plans. Phase 2 Installation of hardware Phase 3 Establish communication between Scania and InductEV´s system Phase 4 System tests and demo on Scania test track. All phases were executed according to plan except for phase 3 as the prototype vehicle was outdated and needed to be updated. We also needed to solve software problems that occurred when starting up the vehicle. We had margin for this in the master plan and kept the planned end time.
