BMW has always been an iconic leading brand in the pursuit of technology and the introduction of products, whether it is in the field of four-wheeled cars or commercially available two-wheeled motorcycles. ?
The latest BMW patent application documents reveal that the car manufacturer is currently developing a wireless charging device, which will become a major revolution and innovation in garage supplies. Whether it is a conventionally powered motorcycle or an electric motorcycle, it is inevitable to charge the battery. In particular, pure electric motorcycles require electricity to cope with normal riding. ?
In order to improve the convenience of charging, the BMW car manufacturer’s idea is to eliminate the annoying charging cable insertion and introduce wireless charging technology that everyone may be familiar with on smartphones. Once the technology matures It is a very revolutionary thinking that can greatly improve the convenience of charging at home and in public parking spaces. ?
BMW is actually not the first car manufacturer to develop wireless charging technology. The reason is that the introduction design of wireless charging is currently limited by technology, but for ordinary motorcycles it is already The reason for the relatively mature technology is that the BMW car manufacturer uses the parking rack used by every motorcycle when it is stationary as a grounding path. Whether it is the center support or the side pillar, it is used as a charging grounding entrance. Once the vehicle is parked, In the set wireless charging parking grid, as long as the parking column is in contact with the ground, wireless charging of the battery will begin. ?
The difficulty with this technology for electric vehicles is that the four postcard-sized rubber tires that touch the ground when the car is parked cannot form a good grounding. ?
Wireless charging is a very mature technology used in mobile phone charging. The reason why it has not been popularized in every smartphone is the cost, but we believe this is the future trend. ?
Wireless charging basically uses Faraday’s law in electricity to connect electricity and magnetism, so the unique motorcycle parking side stand has become the most natural and flawless part of this wireless charging concept. The key is, once you have good grounding and conduction, the other parts are a matter of course. ?
I believe that anyone who has used wireless technology to charge mobile phones will know that although this technology is mature and feasible, its charging efficiency cannot be compared with the general plug-in charging method. This part is indeed a current trend. The technical bottleneck is the focus of research and development currently being carried out by BMW. From the information currently available, it seems that BMW will install traditional and wireless charging technologies on vehicles during this process. The traditional charging technology is suitable for all charging stations. Charging services can be used in parking facilities, while wireless charging technology that requires a relatively long time is suitable for use in your own garage. ?
We can expect that BMW will install this technology and high-convenience value-added equipment on commercially available motorcycle models. By then, the wired traditional chargers that are already in every household’s garage will gradually The ground has been replaced by wireless charging technology. At the same time, this design also opens a new door for the new technology of motorcycle storage and charging. It will never happen again that you forget to charge and ride out of battery.
