Talk about the new energy car wireless charging: How far is it from us?

In 2017, the global new energy vehicle sales exceeded 1 million director, and the new energy vehicle that flourishly drove the development of related technologies, and wireless charging technology is one of them.. The concept of wireless charging technology has been proposed in the 19th century, and there are research institutions to carry out technical research and development; after 2007, wireless charging technology has entered the rapid development stage; around 2010, the automotive industry has begun to carry out relevant technical applications.

In recent years, wireless charging has become a hotspot, and many parts suppliers, vehicle enterprises and technology companies have launched new energy vehicles wireless charging.. Kia successfully tested wireless charging technology has expensive luxury cars to enjoy.

Recently, Kia Motors announced that after three-year fast charge wireless technology, they have now cooperated with the US Wireless Charging Technology Company Mojo Mobile and Energy Efficiency and Renewable Energy Energy Office, and wireless charging in a Soul electric car team. The test work, Soul electric cars are also the only electric car type currently sold in Korea..

It is reported that this wireless charging technology can supply a capacity of more than 10 kilowatts for the automobile, and the charging efficiency can reach 85%.. It is worth noting that even if there is a deviation of the charging device, it does not affect the normal operation of charging, which is absolutely good news about the driver of parking technology.

. The wireless charging of the electric car is similar to the wireless charging of the mobile phone. An electromagnetic field is formed between the transmitting and receiving coils, and the transmission of electrical energy is realized.

. However, the wireless charging of the mobile phone is the same, the electric vehicle will also have energy loss in the process of wireless charging, so the automotive manufacturer and research institutions are currently as high as charging efficiency..

It is also said that the current wireless charging system is still unable to achieve production, but there is a significant increase in the increase in energy output and efficiency.. Static wireless charging: Parking is charged to the end of 2017, the mainland car announced that the wireless sensing charging board equipped with the sensor.

It is understood that this wireless charging network system is important to place an electromagnetic in the underground charging plate, and the induction coil on the car receives electromagnetic and charging the electromagnetic conversion principle.. The system combines with the micro navigation device, allows the vehicle to accurately stop above the charging board, and the accuracy rate is 10 times higher than the traditional parking assist system.

. The mainland company said that the power of this wireless charging system can reach 11 kW, the efficiency is as high as 90%, the charging is 1 mile, 20 minutes per charge for 20 minutes..

It is reported that the technology has been equipped with the BMW 530E model, and it will be applied to the Mercedes-Benz model in the future.. In addition, the mainland group is currently studying a wireless charging transmitter for the parking lot, so that electric vehicles can also perform a small amount of charging at any time during driving.

. Evatran’s PluglessPower System was earlier in 2016, and Evatran has developed a PluglessPower system that supplies wireless charging for Tslamodels..

The system includes two parts, a charging plate and an adapter. The charging board is placed on the ground or parking space, connected to the power supply; the adapter must be professional at the bottom of the electric car. Simply, through the adapter to accept the electric power of the charging board, implement wireless charging.

After the installation is complete, the user can charge the car on the charging board, and the charge is 20 miles per hour. It is filled with Models for 10 to 12 hours, depending on the battery capacity..

According to reports, EVATRAN supplied wireless charging system, wireless sensing 7.2 kW per hour, enough to ensure the daily charging of Models. Dynamic wireless charging: Follow the opening of the Halo 2017 May 2017, Qualcomm announced the test of wireless charging in electric vehicles, namely new induced charging equipment on the road, so that the car can charge while driving.

It is reported that in the event of 100km speed, the wireless charging power of 20 kW is reached, and the vehicle is wirelessly charged while the two vehicles are tested.. Unlike most of the sensing charge, Gao Tong Halo technology can supply high energy transmission, and apply to a variety of models.

. It uses multi-coil design, even if the charging board is not aligned, it can still perform efficient energy transmission..

WitricityWitricity is a startup in the Laboratory of Massachusetts Institute of Technology, focusing on wireless charging technology for more than 10 years.. Important, magnetic resonance-based wireless charging technology, using the near-field spatial magnetic field to perform energy transfer, and accurately adjust the power and acceptance devices with accurately adjustment between the selective energy exchange between the high-efficiency coupled resonators.

245 patents. Witricity’s wireless charging is similar to Qualcomm Halo technology, so it is also its competitor. However, Witricity does not intend to create the hardware used in the automotive wireless charging system, but awarded its intellectual property license to the partner supply to construct hardware reference design.

. At present, Witricity has cooperated with Toyota, General, Nissan..

Car wireless charging, prospects are understood, and the advantages of wireless charging are important in three aspects: Working conditions can also be used normally. ● The second is high reliability, and the wireless charging is not mechanically worn compared to the wire charging..

● The third is that the convenience is good, you can realize automatic charging, solve the problem of unmanned last kilometer convenience. However, in the process of gradually accelerating the development of wireless charging industrialization, it encounters constraints in the standard uniform, less engineering practice and high application cost..

Although in the face of many problems, in the case of new energy vehicles, the application and popularization of wireless charging technology may only be a problem.
