Concrete-Embedded Inductive Wireless Charging Apparatus for Electric Vehicles Reinforced with Fiberglass Rebar

USU researchers have developed a concrete-embedded fiberglass rebar for wireless inductive power transfer (WIPT) systems.

Problem

WIPT systems typically include a primary pad. Embedding the primary pad in concrete can allow for seamless roadway integration and reduced maintenance cost. Steel rebars are typically used to reinforce the concrete slab and help maintain its structural integrity during transportation. However, the presence of steel, which is a ferrous material, affects the electrical performance of the WIPT system. Additionally, the steel erodes as it expands, potentially breaking the concrete. Solutions to increase durability and efficiency of WIPT systems while maintaining the structural integrity of the pre-cast concrete are needed.

Solution

This fiberglass rebar mitigates the adverse effects of steel rebars on concrete-embedded WIPT systems.

Benefits

This fiberglass rebar:

• provides coil design flexibility without sacrificing the integrity of the concrete it’s embedded in
• is four times lighter than steel alternatives, yet twice as strong and less likely to deform under impact
• has corrosion resistance to a wide range of chemicals
• extends the life of concrete structures
• lowers installation and maintenance costs

Applications

This fiberglass rebar is useful in concrete-embedded wireless power transfer for any type of road, such as highway or city roads.
