“…The distance and coupling have an inverse relationship. [22] The coils dimensions are also important. Similar to the last example, .there will be little coupling between the primary and secondary coils if there is a big difference in their diameters this can be seen from figure -5.…”

These days everything runs on electricity, without electricity it becomes hard to spend time. Our daily use items like phones, laptops, and other items work on electricity. So electricity is our basic requirement and its connection is establishing rapidly. This is a great opportunity for us to shift to an electric vehicle as nature warns us of pollution. Also, there are different sources available for generating electricity and this electricity can be easily used to move the car. To move the car through electricity, an electricity bank i.e., batteries are installed inside the car which needs to be recharged after a fixed mile run. This recharging can be done in different manners but the need of better fast and efficient charging system has been increases. People don’t want to carry different chargers for different devices or wait for long hours at changing stations so to make charging in an easy way this paper purposed a charging system based on wire-free technology. This paper elaborates on the concept of wireless charging and improves the concept of stationary wireless electric car charging.

“…The IPT implementation in [57] is a more direct comparison to existing CPT; this laboratory scale prototype achieved 5 kW of output power with 92.5%. Similarly, the findings of [58] indicate 92.5% efficiency for variable PT up to 3 kW. In practice, the PRIMOVE system by Bombardier is a real-world implementation of an IPT system for transport, capable of achieving fast 200 kW charging to an electric-bus system in Södertälje, Sweden [59].…”

“…In the EV charging environment (or LRV charging environment), the CPT coupling is often relisted as CPT plates placed in the road and on the underside of the chassis. The moving nature of the receiving plates creates a dynamic changing environment where the load varies with time [58,80]. Due to load variation, it is common for voltage ripples and power fluctuations to occur and cause increased stress on the components of the CPT system [80].…”

Light rail vehicles (LRVs) are increasingly in demand to sustainably meet the transport needs of growing populations in urban centres. LRVs have commonly been powered from the grid by direct-contact overhead catenary systems (OCS); however, catenary-free direct-contact systems, such as via a “hidden rail”, are popular for new installations. Wireless power transfer (WPT) is an emerging power transfer (PT) technology for e-transport with several advantages over direct contact systems, including improved aesthetics and reduced maintenance requirements; however, they are yet to be utilised in LRV systems. This paper provides a review of existing direct-contact and wireless PT technologies for LRVs, followed by an in-depth critical assessment of inductive power transfer (IPT) and capacitive power transfer (CPT) technologies for LRVs. In particular, the feasibility and advantages of CPT for powering LRVs are presented, highlighting the efficacy of CPT with respect to power transfer capability, safety, and other factors. Finally, limitations and recommendations for future works are identified.

At present, the mobility sector in Europe is in the middle of a transition phase. Combustion engine-based vehicles (CV) are meant to be replaced by electric vehicles of the same type in order to fulfill the zero emissions targets within the next decades. This requires a collaborative approach from the industry, research institutes, and national governments in order to prepare both the necessary vehicle technology and infrastructure accordingly. Even though various attractive charging solutions in the hundreds of kilowatt range already exist commercially, heavy-duty vehicle charging in the multi-megawatt range is still a topic to be investigated in more detail in the scientific community. Therefore, this publication discusses different strategies to enable fast charging in the megawatt range and presents a concept that is directly connected to the medium voltage grid while enabling distributed charging and an optimized carbon footprint due to the adoption of renewable energy systems.
