· Application Case of Power Adapter Based on Xinhai Technology CPW3301

Generally speaking, the application architecture of fast charging adapters mainly includes three modules: AC-DC conversion module, power control module, and fast charging protocol module. Among them, the AC-DC conversion module is responsible for converting 220V AC power to DC power, the power control module is mainly used to adjust the DC voltage to the voltage required by the phone, and the fast charging protocol module is responsible for shaking hands with the phone to communicate, collecting voltage, current, and various information requested by the phone.CPW3301 not only integrates power control module and fast charging protocol module, shouldering the core task of the entire fast charging process, but also specifically solves a series of pain points of current power adapters in the market.Firstly, the power management module of CPW3301 has high integration and rich functionality. This chip integrates two of the three main modules of the fast charging adapter: the power control...

· BMS and Wireless Technology of Electric Bicycles

Electric bicycles are green, clean, convenient, and low-cost, making them a popular choice for many residents. With the widespread application of electric bicycles, safety accidents caused by issues such as wiring and charging are becoming more common. The capacity, safety factor, health condition, and endurance of electric bicycle batteries have gradually become a focus of attention.On March 26, 2019, the Ministry of Industry and Information Technology announced that the new mandatory national standard for electric bicycles, "Safety Technical Specifications for Electric Bicycles," was officially implemented on April 15, 2019. Although the country has not yet decided to phase out lead-sealed batteries, the trend of replacing lithium-ion batteries with lead-sealed batteries and intelligentization for electric bicycles has become inevitable. Compared to the widely used lead-sealed batteries in this field, lithium batteries have advantages such as high operating voltage, small size, hi...

· Power Adapter: a Bridge Connecting Different Worlds

In daily life and work, we often hear the word "Power Adapter". So, what exactly is power adapter? In short, an adapter is an interface or converter that enables connections, communication, or collaborative work between different devices, systems, or software. It is like a bridge connecting different worlds, allowing us to operate and communicate easily in diverse environments. 1.Definition and Function of AdaptersPower adapter, as the name suggests, is a device that can adapt and convert. In the field of computer science, an adapter typically refers to a hardware or software component that can convert an interface of one device, system, or software into an interface that another device, system, or software can recognize and use. Through this approach, adapters achieve interoperability between different devices, systems, or software, expanding their functionality and application scope.The main functions of power adapters are reflected in the following aspects:Interface conversion:...
