Advantages of wireless power systems in automotive applications
With the application of embedded modems, telematics equipment and wireless connectivity, more and more cars are starting to have wireless networking capabilities. But at present, sensors, cameras, computing control units and other in-car facilities are still connected through a complex cable wiring. The use of wireless power systems can greatly simplify the use of cables, optimize vehicle design, and make more on-board functions possible.
Fewer car cables
In-vehicle information processing equipment, sensors and other types of in-vehicle instrumentation usually require two power cables and two data cables each.
The use of the wireless power system will greatly reduce the cable required for the connection of the equipment in the car, and all the on-board equipment can be connected with only one cable that has both data and power functions and runs through the body.
The wireless transmission of electric energy mainly relies on resonant electromagnetic induction, which can transmit power and data information with a frequency between 50mW and 1 kW.General Motors recently announced that it will provide wireless charging devices in its models to charge mobile devices in the car.
In addition to simplifying the use of cables, wireless power systems will also bring other improvements, such as reducing material production and assembly costs, and enabling more flexible and efficient vehicle design.
More flexible design
The single vehicle cable system enabled by wireless power will give automakers greater flexibility in designing body power facilities and body construction, and will make more on-board functions possible.
For example, with the support of the system, the door can be removed from the obligation to support complicated cables, the rear seat display does not have to be connected to the vehicle's operating interface, and mobile positions such as the front seat or headrest can be moved more flexibly. In addition, in the case of trailer service, cars equipped with wireless power will no longer have to rely on cables with signal plugs to connect to the trailer.
Possible challenge
Applying in-car wireless power has some unavoidable challenges. For example, it is necessary for car manufacturers to modify some components and equipment of cars to make them suitable for wireless power systems, and this process can take several years.
Before wireless power is fully promoted, car manufacturers may be able to experiment with independent subsystems such as parking assistance systems that are more suitable for wireless power connections.
