type-cAnalysis of the key points of fast charging research and development design
Today's mobile devices are commonly usedType-C fast chargingInterface charging, the length of charging time directly affects the user experience. Therefore, how to design a fast charger has become the focus of research and development by various companies. The following will introduce the key points of Type-C fast charging research and development design.
First of all, the problem to be solved is the charging current. The current is a key factor affecting the charging speed, and it should depend on the battery limit and safety of the mobile device. If the battery charging current is too large, it will accelerate the battery decay. For 20V\/3A high For a high-power charger, the charging time needs to be within one hour, and the heat problem must also be considered. During the design process, the internal heat dissipation of the charger needs to be designed.
Secondly, the core technology of Type-C fast charging is the fast charging protocol. Different devices have different charging protocols, some devices support PD3.0 fast charging protocol, and some devices support QC3.0 or SCP, so you need to pay attention to it when developing and designing Adaptability of the charging protocol.
In addition, the key points of Type-C fast charging research and development design are as follows:
1. Optimization of the fast charging protocol: Most of the current fast charging protocols are formulated according to their own standards, so it is necessary to optimize the fast charging protocol in product development and formulate it according to the actual situation.
2. Chip technology innovation: Chip technology is the core part of fast charging technology. In the process of research and development, it is necessary to innovate chip technology, improve energy efficiency, and reduce electric power.
3. The safety of the charger: The safety of the charger is extremely important, and problems such as linear changes, short circuits, and overvoltages during long-term use must be considered to prevent potential safety hazards caused by circuit failures.
4. Quality control: To produce a standard, stable and reliable fast charging product requires a high level of quality control. Therefore, in the production process, it is necessary to ensure the reliable quality of each link, and carry out quality control through a strict management system.
To sum up, the key points of Type-C fast charging R&D and design mostly focus on current control, fast charging protocol optimization, chip technology innovation, safety and quality control, etc. Only when these key points are scientifically and accurately Design can produce high-quality fast charging products that meet market demand and bring consumers a good experience.
