A Comprehensive Guide To Cars With Wireless Charging

As electric vehicles become more prevalent in the market, various modern technologies related to them are emerging. Wireless charging is one of the most advanced systems in the modern world. Wireless EV charging utilizes resonant electromagnetic induction to transfer electrical current, which is why it is also known as inductive charging technology. 

Wireless charging for electric vehicles is considered very efficient and fast. Cars with wireless charging have also become a popular trend in the automotive market. In this article, we will discuss what cars with wireless charging are, how they work, and their benefits. 

What Does It Mean by Cars with Wireless Charging?

A car with wireless charging frees an electric vehicle from the need for a cable to charge it. It further adds to the convenience of charging EVs at work or home. You can easily park your car in a designated location, and the steering can also be automatically operated. According to the instructions, the EV driver can park their vehicle at the desired spot simply by using the accelerator, shift, or brakes. Because of this, you can greatly reduce the hassle of parking as well. 

How Wireless EV Charging Works?

Like mobile phones, cars with wireless charging have a magnetic coil in the charger. This coil transmits current to a magnetic coil located on the underside of the vehicle. When these two pads align, the car’s charging begins. 

Wireless charging is considered to be as fast and efficient as charging with a plug. For instance, an EV plug charger gives an 80-95 % EV charging efficiency rating. At the same time, a car with wireless charging will show a 93-95 % efficiency rating. Wireless charging also provides up to 20kW of charging power, mainly a level 2 charging speed. Furthermore, there are also no technological limitations that prevent higher speeds. 

Wireless EV Charging Options

Wireless EV charging comes in two different types. These include static EV charging and dynamic EV charging. 

Static EV charging 

This type of EV charging is the most similar to what EV drivers do now. Static EV charging implies that your electric vehicle is not moving while charging. Instead of plugging in the charger, a car with wireless charging will have equipment to park over the installed wireless charging coil. These are usually installed in a designated space or location. 

Dynamic EV charging

Induction or wireless charging is eventually expected to be built on roadways so that EV drivers can charge their vehicles continuously as they go. It will operate similarly to regular induction charging and is also expected to work smoothly at speeds up to 65 mph. It allows EV owners to drive long distances without stopping for a charge. Plus, you are not worried about the risk of running out of power.

Benefits of Cars with Wireless Charging

Wireless EV charging has several benefits, especially in the modern, evolving world. Commercial vehicles can particularly benefit from this charging type.

No Wires

As you can get an idea by the name, wireless EV charging requires no wires. EV drivers do not need to carry heavy charging plugs or cables. They do not need these wires at every charging station to plug into their cars. Hence, you do not need to worry about range anxiety. The EV owners can park their cars over a charging pad. The charging process will start automatically, which makes it user-friendly. Since there are no physical connections, less wear and tear is found on the wireless charging infrastructure and the charging port of the EV. It potentially leads to reduced maintenance costs and increased longevity. 

Reduced Accident Risk

EV charging cables may get damaged over time. These damages are usually noticed, particularly in extreme cold and hot areas. If your cables are not in good condition, they can be hazardous to the vehicle and its owner. Wireless means fewer risks, and replacing cables is also expensive. Moreover, the absence of exposed cables minimizes the risks of tripping hazards and electrical accidents. Therefore, wireless EV charging can be safer, particularly in public spaces.

More Convenient

Wireless charging is simply more convenient. Even though it is only available as static charging right now, it is still convenient. Considering this, imagine how convenient it would be if dynamic charging became a reality. 

Saves Time

Although wireless charging is not much faster than regular EV chargers, you can save a little time. It is so because you do not have to get out of your vehicle, plug-in, etc. Furthermore, if dynamic charging becomes a reality, you will save substantial time on charging. 

Sustainability 

Wireless charging reduces the production and disposal of charging cables. This will ultimately lead to a more sustainable and greener future with fewer carbon footprints. Plus, cordless charging is also a great eco-friendly alternative to traditional charging methods. You can also integrate wireless charging systems with renewable energy sources like solar panels, which can further improve the sustainability features of electric vehicle charging. 

Future-Proof Technology 

Wireless charging technology, also known as induction technology, is constantly evolving. Ongoing research and development in this field bring new advancements to the industry. As EVs continue to gain popularity, wireless EV charging is expected to improve in different ways. These may include charging speed, efficiency, and compatibility. Investing in wireless charging infrastructure now can boost future compatibility with advanced EV models and upgrades. 

Cons of Wireless EV Charging

Every technology has its cons, and some factors keep them a little bit behind. Some of the cons of wireless charging are discussed below.

Wireless charging usually has lower energy efficiency than traditional wired charging. Because energy is transferred wirelessly, there can be energy loss during the charging process.

Wireless charging needs precise alignment between the EV receiving coil and charging pad for effective charging. 

Alignment deviation can result in a decrease in charging efficiency or sometimes complete failure to charge.
