Why Are There Green License Plates?

Green license plates represent new energy vehicles, which are divided into two types: pure electric vehicles and hybrid vehicles. The license plates for pure electric vehicles are green, with the first letter after the provincial abbreviation being D. For hybrid vehicles, the letter is F. Therefore, simply by looking at the license plate, one can easily distinguish that a green plate indicates a new energy vehicle, with D representing pure electric and F representing hybrid. New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures.

Why can't Porsche CarPlay connect?

Here are the reasons why Porsche CarPlay cannot connect: 1. Reasons: The mobile phone data cable is damaged or disconnected; the metal contact terminals on the USB plug or the phone plug have foreign objects or are oxidized; the connection between the car host and the external USB HUB is loose; the USB female port inside the external USB HUB of the car host is damaged, and the contact metal piece has poor contact with the USB male plug. 2. Others: If it still cannot connect, you can insert a U disk containing songs or videos into the USB-HUB to see if it can read data. If it can read data, it indicates a problem with the phone. If the U disk cannot be directly connected to the host through an adapter but can read data, it is a USB-HUB fault. If it cannot read data, it is a system host fault.
