According to the development trend of current consumer electronics products and unified regulations of the European's latest charging interface, USB Type-C will be the mainstream interface of consumer electronics products and some industrial products in the future. At present, the USB Type-C and USB PD are also rapidly supporting the current hot new energy vehicle manufacturers. The emerging USB Type-C connection standard has begun to be applied in front of the automotive system, and expected to obtain significant in automotive connection progress.
With the widespread popularization of portable electronic devices, users have become more and more frequent when driving. USB power supply function makes the device charging extremely convenient.High data rate of USB allows the new generation of information and entertainment systems to support rich and diverse vehicle functions, such as audio playback, screen and application sharing, and data connection. Traditional USB Type-A interfaces have been widely used in various models of automobile OEM manufacturers, with a maximum power supply capacity of 7.5W (5V voltage and maximum 1.5A current). With the rapid popularization of the USB Type-C interface on PCs, smartphones and other portable electronic devices, the USB Type-A interface is rapidly eliminated. Compared with USB Type-A interface, USB Type-C interface structure is more compact, with general connection, which can be inserted forward and reverse. In addition, it can significantly increase the output power, up to 100W (20V voltage, maximum 5A current). Because it provides a power supply that is much higher than 7.5W. It can achieve a new mode of usage which can be charged quickly, and charge the active equipment that are continuously increasing in the car at the same time, such as mobile phones, tablets, laptops, and even electricity. A few days ago, after Huawei AITO M5 Car, AITO M7 was once again equipped with 4 Type-C charging ports, up to 66W fast charging.
The rhythm of our time is constantly accelerating, and we need to charge our equipment faster and more frequently. If you have 100W power supply, you can charge the laptop and mobile phone at the same time in about 15 minutes. To implant the USB Type-C interface with a new generation of power supply capacity, the work involved is far from increasing the oral voltage and current of the power supply end. Essence And improving the power supply capacity is the key to car USB port. Although users can use Type-A to USB-C adapter to charge the new mobile phone through the old ports on the car, but this cannot show full play to the advantages of the USB Type-C interface. Although a new generation of mobile phones with USB Type-C interface have fast charging capabilities, it is subject to the 7.5W power supply capacity of USB Type-A interface. Obviously, full-power supply will play an important role in customer satisfaction and model differentiation. Generally speaking, car OEM manufacturers do not need to provide a full power 100W power for every USB Type-C port on the car. In order to reduce costs on the premise of not seriously affecting charging time or reliability, 100W power supply power can be shared between multiple end -ports to achieve so-called dynamic load sharing. In the case of a total power of 100W, with the corresponding firmware, when the second device is inserted, USB PD controller can be intelligently allocated to reduce the power of a USB Type-C port to 60W, and the second insertion is inserted in the second insertion The device can get 40W power. In the past, in order to reduce costs, 100W power supply power can be shared between multiple end -port, that is, the so -called dynamic load sharing, a single device is charged at 100W power; after the second device is inserted, the two devices can share the power provided by the port. With the innovation and development of industry technology, many technical bottlenecks have made breakthroughs, and the USB PD standards that transmit charging have also evolved and developed with time. For example, the current standard supports Power Delivery 3.0 and Quick Charge (QC) 4.0 with a programmable power supply (PPS) function. If any specification in these specifications changes (in fact, the USB Type-C specification and the PD specification have been changing), cars may not be fully compatible with new equipment in the market. The only way to achieve high -reliability and interoperability is to use a programmable USB controller. Using the programmable controller helps to upgrade the USB PD protocol stack to enable it to achieve interoperability with the latest devices, and this requires a breakthrough in the core of chip manufacturers based on Cyprus.
Because consumers need faster charging and more connection options, USB Type-C has also rapidly popularized in the automotive field after the rapid popularization of consumer electronics. The maximum support of 66W fast charging is also a microcosm of many application cases. In the future, more new models will provide Type-C connection. From 2017 to 2026, the compound annual growth rate of USB Type-C will be 110%. Expected that global shipments will exceed 55 million by 2026. "Such situations have often occurred in the past ten years: the consumer electronics market is a leading indicator of automotive technology trends in the car. Consumers are increasingly looking forward to their vehicles with them. Compatible with mobile devices and attachment equipment. "USB Type-C is a powerful multi-functional standard that provides various power and data configuration for built-in devices. "
