In 2020, consumers spent $120 billion on electric vehicles, up 50% from 2019, which drops to 41% of sales and 6% of sales growth. electric car prices. Soon every family will have an electric car. It’s been ten years since there was a massive onslaught on EVs. Rising gas prices and the environment are driving consumers away from conventional cars. More and more users are moving towards using Electric Vehicles. Current automakers, such as Honda, Toyota, etc., are shifting their supply lines to EVs. One of the main reasons for this growth is that the price of gas is rising, and the cost of buying EVs remains relatively high (source).

Wireless Charging Technology And The Future Of Electric Transportation

We will be publishing a series of blogs focusing on EV Charging. We will discuss technology, Industrialization, Communication & Marketing, Importance of Intellectual Property and Patents, and more. This blog is the first of many.

The Ultimate Guide To Wireless Charging

EV charging technology has been around since the early 1900s, when General Electric first introduced battery swapping for electric vehicle batteries. In ten years, the US Department of Energy has built 18,000 homes, businesses, and individuals (8000 civilians). You may have heard some local news about a new power plant being opened in or near your city by an auto company. EV development is progressing rapidly in the US, China, and Europe. We would be seeing more enforcement by now if it weren’t for the rise in popularity of gas cars.

According to recent developments, ABB’s terra 360 modular charge can simultaneously charge up to 4 cars and charge a car in less than 15 minutes. Another UK based company Voltempo claims to sell cars using hyper charging in less than 6 minutes; interestingly, the company has no important patents.

There are other ways to manage the wait time. For example, Starbucks works with Volvo and ChargePoint to install charging stations in its parking lots. So, when you’re in Starbucks and get your food or coffee, your car is being charged! What wonders will be performed after? It’s like an upgrade from Tesla Destination Charging.

It is important to understand the basic concept of EV Charging. But how are electric car parks used? Now to learn what and how to use an electric vehicle charging station.

Charging Electric Cars Is About To Get A Lot Easier

A simple example is paying for an EV from our home. The electricity in our homes uses Alternating Current (AC). An inverter converts the AC power from the grid to DC to transfer to the battery. The battery is charged with Direct Current (DC ) like our phone batteries but at a higher capacity. There are different types of EV Charging

As shown in the image above, below are brief details on AC Level 1, Level 2, and Level 3 controls –

Level 1 is sold as the most expensive, but it also takes the longest to charge the EV battery. Level 1 uses 120 V AC, a standard plug, like a home network. Unlike other combat technologies, there are no additional devices attached to the Stage 1 combat. These values ​​may take up to 20 hours to fill. Webasto, Orion, and others, are among the manufacturers of Level 1 chargers.

Level 2 technology is used for restaurants and commercial buildings. It uses 240 V AC and cannot be plugged directly into a standard wall outlet. Instead, these systems are usually installed by a professional electrician. They can fully charge the electric car battery within two hours up to 7 hours. Level 2 suppliers include Grizzle, ClipperCreek, ChargePoint, Tesla, Siemens, and others.

Research Paves Way For Wireless Charging Of Electric Vehicles

In this more powerful and faster system, the AC from the grid is converted to DC before entering the car, which is in an installation area. They operate with powers ranging from 25 kilowatts to more than 350 kilowatts. DC Fast Chargers can offer as much as 60 to 100 miles in just 20 minutes of charging. They are often used in commercial and industrial settings because they require specialized equipment to install and maintain.

DC Fast Chargers are not used in all vehicles as many plug-in EVs do not have this charging capability.

Charging Wales is the Future of EV Charging. Apart from wired EV Charging, wireless charging for EVs is also gaining traction because wireless charging technology has made it possible to eliminate plugs and wires. Siemens, BMW, WiTricity, Qualcomm, and Evatran are some of the major wireless companies targeting EVs. Concept image for EV Wired

It is possible to use the general use of the electric system for EVs only when parked in the parking lot or in the garage, which is combined with the use of the wireless charging system (WCS). The system consists of a transmitter installed underground (connected to a power line), and the amplifier located under the vehicle. The car is lined up on the transmitter, and the receiver and the driver can leave it for charging. The AC power level, the distance between the transmitter & receiver, and the size of their pads affect the time it takes to charge the car. This Static Wireless Charging System is more prominent when an EV is parked for a long time, such as a garage or an office park.

Wireless Charging Is The Future Of The Electric Vehicle Industry

As the name suggests, the car is charged when it moves. The electricity is transferred over the air from a fixed transmitter to a receiver coil installed in a moving vehicle. An EV is charged when it is driven on horizontal coils mounted under the road in this installation. Qualcomm and ElectRoad have successfully tested energy-efficient vehicles while they are in motion. These are intended to be displayed on buses or transit vehicles traveling on fixed routes.

The number of companies in the EV Charging space is growing. As technology becomes more innovative and more demanding, patenting technology becomes important for car companies to make significant and original moves. a strong foundation for themselves. As for patents, it is likely that we will see licensing or cooperation between competitors to bring new technical skills. These decisions will be important and will require a solid understanding and sense of judgment as to what types of IP are most useful and usable.

The picture below presents the list of the most appointed people for granted patents and lives in the field of EV Charging.

A company should focus on an initial IP plan to move forward and expand its business vision. One of those examples is Witricity which acquired over 1500 assets from Qualcomm related to Wireless Charging in 2019. We will cover more information in other blogs.

He comes with expertise in Telecom, Networking, and Wireless Standards such as ETSI, IEEE, RFCs, etc. He has extensive experience in conducting and designing test cases for various Bluetooth and Wi-Fi applications. In addition, he contributed to a general Industry research report on Wireless Charging. Consumer buy-in is the key to the future of a transportation sector that is largely replaced by Electric cars and trucks today. Oak Ridge National Laboratory scientists have for years been developing a technology called wiring that can make it easier, or even easier, to power an EV than filling a car with gas. Researchers are now close to perfecting a new system to charge EVs while they are moving.

Electrifying transportation is at the top of the list for solutions to clean up America’s economy. The transportation sector is the largest emitter of greenhouse gases in the country, with cars and light vehicles accounting for only 60% of emissions. The Department of Energy has supported several initiatives to make EV ownership easier and more affordable for consumers, including the goal of a 15-minute or less charging time. eat

With traditional magnetic technology, silicon carbide-based electronics, and innovative control and protection technology to handle heat , the scientists have proven that their device can operate both a lightweight passenger vehicle on a six-inch air gap and a space-duty spacecraft. car delivers over an 11-inch air gap at a maximum of 20-kilowatt at more than 92% power conversion efficiency – the same as a cable machine. Energy can also flow in both directions, allowing cars to store energy.

Volvo Cars Tests New Wireless Fast Charging Technology

Researchers have successfully demonstrated a 120-kW wireless charging system with 97% efficiency, and plan to install high-voltage systems, up to 270-kW, on passenger cars to meet or exceed 15-minute charging targets.

The research is supported by the DOE Office of Energy Efficiency and Renewable Energy’s Vehicle Technologies Office. Systems are developed and evaluated at National Transportation
