All you want to know about car wireless charging (front + rear) is here

As an excellent wireless charging application field, car wireless charging is an artifact to improve safe driving and the quality of life of car buyers. It greatly improves the feeling of mobile phone use and battery charging in the car.

In order to better let us have a comprehensive grasp of car wireless charging (front and back), what we need to produce today is detailed explanation and market demand analysis.

1、 On board wireless charging method: front loading and rear loading

At present, there are two methods of on-board wireless charging: front charging and rear charging. Popularly speaking, front loading means that the car has a wireless charging device in front of the original factory, which is generally located in the middle of the storage box and armrest box. The battery can be charged by putting the battery charging device on the mobile phone. The rear mounting is to refit a vehicle mounted support frame and other equipment on the car to complete the wireless charging. The installation position is not fixed. It can be installed on the ventilation hole of the central air conditioner, the dashboard and other parts of the car, or it can be absorbed on the car windshield by the glass suction cup.

The technology of wireless charging in front of the car comes from the wireless charging solutions presented by the wireless charging plan providers to the car manufacturers. As a standard car front mounted wireless charger, the verification of wireless charger is only basic, but also needs to consider the harsh car level hardware configuration specification, and has certain level regulations on the operating temperature range, moisture-proof and antifouling.

This includes a series of strict regulations in the field of motor vehicles, such as E-MARK verification, iatf16949, EMC verification and so on, which are usually strict, costly and time-consuming. As a result, there are few wireless charging manufacturers in the front loading sales market, and their qualification certificates are not up to standard.

As for the on-board rear mounted wireless charger, it is not a part of the whole vehicle and will not be subject to the mandatory verification specifications of many automobile manufacturers. Therefore, the credibility of the product is not as good as that of the front mounted one. However, it is better than that of the front mounted one in terms of low threshold of entry conditions and high cost performance.

1. New on board front mounted wireless charging car series in 2019: 161 models

By the end of 2012, Toyota had already announced the 2013 Avalon, becoming the world's first car with the wireless charging function of Qi agreement. After the Siri technology of iPhone was introduced into the car, the technology of wireless charging was also brought to the car.

According to the data of auto family (as of July 13, 2019), there are 1238 models in China's sales market at this stage, among which 161 models are suitable for wireless charging on mobile phones, accounting for about 13%. It must be stated that each of these models includes several to more than a dozen car lines. For example, Audi A8 has eight car lines, Mercedes Benz S-class has 13 car lines, and BMW 7 series has 24 car lines, which are suitable for wireless charging on mobile phones. As a result, a total of 20% of the cars in the market are suitable for wireless charging on mobile phones.

Let's analyze the data. Among the 1238 models on the market, there are 706 domestic cars, of which 78 are suitable for wireless charging on mobile phones; 270 joint venture SUVs are suitable for wireless charging on mobile phones, 28 are suitable for wireless charging on mobile phones; 261 imported cars are suitable for wireless charging on mobile phones, 55 are suitable for wireless charging on mobile phones.

In addition, looking independently at the 161 models suitable for wireless charging on mobile phones, 78 of them are domestic cars, accounting for 48%, accounting for nearly half of the market share; 28 of them are joint venture SUVs, accounting for 17%; and 55 of them are imported cars, accounting for 34%.

2. Wireless charging sales market for vehicle rear mounted

The first type of rear mounted vehicle wireless charging is a special vehicle wireless charging, which is a commodity customized by the third party manufacturer for special vehicle series. The original factory data information is molded and embedded combined with the design scheme. The specific is back decoration, but the visual effect is similar to the actual effect of front loading.

The second type of rear mounted vehicle wireless charging is a vehicle wireless charging support frame, which is more common. The key of the on-board wireless charging support on the market includes four categories: infrared sensor support, force support, magnetic absorption vehicle support, video voice vehicle support, etc.

Among them, the infrared sensor support frame must be motor and infrared sensor, and the force support frame is equipped with pure physical mechanical system. The magnetic absorbing vehicle support frame is connected according to magnetic absorption, and the video voice vehicle support can cooperate with app application, and it has the function of intelligent voice assistant.

2、 Qi verification of the main performance of the sales market of vehicle wireless charging

Based on the strategy analytics data, Qi verified that the sales volume of the on-board wireless charger in 2018 exceeded 12million units worldwide, with a year-on-year growth rate of 101%. This includes pre installed charging head (i.e. wireless charging in front of vehicle), and charging head of after-sales service marketing market designed for vehicle application (i.e. wireless charging after vehicle).

For wireless charging before vehicle loading, most automotive fields have already made Qi the specification of battery charging in intelligent locomotives. In April 2018, WPC customer survey all over the world showed that 45% of customers expect to apply wireless charging in their vehicles, and the data information in China is 32%. (* WPC 2018 Global Consumer Study with Toluna Research – April 2018)

WPC also shows that the new products released by the manufacturer of wireless charger installed in front of the vehicle have been selected for verification. The new vehicle wireless charging information of vehicle which has been verified by Qi after march31,2019 is EPP type.

Here is a brief introduction. There are two key types of Qi verification based on output power size: one is BPP, 5W and the following; the other is EPP, 5W to 15W. The higher power EPP verification can undoubtedly produce a stronger wireless charging experience.

3、 Summary of khaka Technology

As a very high frequency wireless charging application scenario, vehicle wireless charging is convenient to use and safe. The two hands are released in one hand mode. For the main performance of the car wireless charging market, whether it is front or rear loading, there is also a very big trend of development to increase indoor space. In the new trend of wireless charging, we also see the future performance of this key wireless charging scenario.
