CARDHIN – Dynamic Inductive and Hydrogen Dynamic Charging for electric vehicles based on Renewable Sources

National Project


CARDHIN (Hydrogen and Inductive Dynamic Charging for electric vehicles based on renewable sources) is an industrial research project led by API MOBILITY (ACS Group) with the participation of SICE (ACS Group), PREMO, ISOTROL, INFORNORTE, ARIEMA and APTICA.

The objective of the project is to research and develop a functional prototype in a relevant environment (TRL 5) of an Inductive Dynamic Charging System on the road, which allows the recharging in motion of electric vehicles and particularly of heavy goods vehicles.

The project will investigate different technologies:

  • Induction
  • Antennas for dynamic loads
  • Magnetized concrete type materials
  • Communications
  • Energy Management
  • Use of renewable H2 for road energy support

These technologies aim to generate knowledge and place Spain at the forefront of these technologies, developing a holistic vision that considers the totality of the required infrastructures, the costs of their total life, the recyclability of their components, the impacts of all types and the resilience of the solution. To this end, the project will place special emphasis on the points that have been identified as the weakest in previous projects, as well as on others that have hardly been studied in depth, such as the characteristics and resistance of pavements in the long term.

The need to increase the autonomy of electric vehicles requires systems that help and complement the energy density and efficiency of their batteries. One way to recharge them or maintain a level of recharge would be through road sections, especially those with high traffic density, with this technology to maintain the battery so that vehicles can arrive without stops at their destination, making the last kilometers without needing to recharge at electric stations in the destination areas. The technology is particularly interesting for the decarbonization of long-distance heavy transport, but, as mentioned, it is very likely to have a great development in peri-urban and urban environments.

The project will also update the cost-benefit analyses carried out for the various alternatives for decarbonizing transportation, with a view to the already immediate development of autonomous vehicles, at least in highway environments.

CARDHIN is fully aligned with the “Smart and Sustainable Mobility” mission. In particular, it will focus on electro-mobility through the development of charging systems and infrastructures embedded in the road, which will enable on-the-go charging of electric vehicles, thus promoting viable and feasible mobility models for users that contribute to the reduction of vehicle emissions through the mass deployment of electric vehicles, mainly in long distance transport vehicles, both for passengers and goods. With the expectation that this same technology can be extended to all types of vehicles that need to travel many kilometers without time or opportunity for static recharging, in peri-urban and urban environments. The project is also studying the energy support that renewable H2 obtained directly from renewable sources can provide in the road environment, which will reduce the future environmental impact of electrifying all highways and freeways.


The main objective of the project is to research and develop a dynamic inductive road charging system, using magnetized concrete technologies, together with a transmitting and receiving antenna capable of performing a dynamic inductive wireless charging to the requirements, specifications and regulatory and technical needs of the roads.

Among the overall key objectives would be:

  • Demonstrate the technical feasibility of transmitting to a heavy vehicle (or passenger bus) the average power required to make long freeway journeys at authorized speeds. The battery must be sized as the minimum to:
    • Support the power received from the road in situations of high power demand: long steep climbs and overtaking (where it must leave the electrified lane)
    • Allow sufficient autonomy to the vehicle to reach its destination. This type of transport reaches logistics platforms, where there must be recharging systems of the same type (although in this case it would be static inductive recharging).
  • Show an efficiency in energy transfer that, integrated with the other losses (transmission to the track converters, eventual losses in the vehicle electronics, performance of the electric motors, losses in the partial charges and discharges of the battery) is similar to the efficiency of static or dynamic recharging by contact (catenary or rail on pavement), and clearly superior to that of the use of internal combustion engines that consume bio or synthetic fuels, including compressed or liquefied natural gas
  • Demonstrate the resilience of the solution in terms of resistance of the pavement in which the road part of the system is integrated.
  • Demonstrate a real decarbonization of transport in terms of a high percentage of electrical energy coming from renewable energy sources through the use of the H2 vector.

Duration time: September 2020 – October 2023
