· The difference between single power supply and dual power supply in switching power supply

Single power switching power supplyA single power switching power supply outputs the required DC voltage through a power input, rectification filtering, transformation, voltage stabilization, and other circuits. The single power supply circuit has a simple structure, convenient design, and is suitable for situations with a small voltage range. In addition, single power switching power supplies also have advantages such as small size, light weight, and low cost, making them widely used.Dual power switching power supply Dual power switching power supplyDual power switching power supply refers to the addition of a backup power input and output on the basis of one power input and output. When there is a problem with the main power input, the backup power supply will automatically start and provide power output for a certain period of time to ensure the continuity and stability of equipment operation. Dual power switching power supply is suitable for situations with very high requirements...

· The laptop keeps showing 0% when it cannot be charged, and it immediately shuts down after unplugging the charger

When using a computer, sometimes we encounter situations where even if a charger is plugged in, the charging speed cannot keep up with our usage speed, resulting in an automatic shutdown during the charging process. When we unplugged the charger, it immediately shut down due to the lack of external power support.The reasons for this phenomenon can be explained as follows:Firstly, the power of the charger is insufficient. Each laptop has a minimum operating power requirement, and when using a charger with higher loads (such as running large programs or performing complex calculations) and connected to a low-power (such as a regular household socket), it may not provide enough energy to maintain system operation and fast charging simultaneously.Secondly, there is an issue with operating system settings. Some operating systems may choose to remain on by default and not actively adjust device status or close applications based on the current power supply situation. Therefore, after connec...

· Can different brands of mobile phone chargers be mixed?

Have you ever mixed your phone chargers? Although the functions of mobile phones are becoming increasingly powerful, charging, as an important part of mobile phone usage, has also attracted people's attention. One common question is: can chargers from different brands be mixed? I must explain this issue to everyone carefully, and I hope everyone can gain something from reading it.Firstly, we need to understand that different brands of chargers can be mixed in most cases. However, when using different brands of chargers, you need to pay attention to the following points:● Consistency of charger specifications: Ensure that the output voltage and current of the mixed charger are the same or compatible with the original charger of the phone. Usually, mobile phones can accept a certain range of current and voltage, so using a charger with a voltage of 5V1A or higher is usually safe.● Quality assurance of chargers: Try to choose brand original or third-party high-quality certifi...

· How to achieve fast charging of lithium-ion batteries?

The key to achieving fast charging of lithium batteries is to optimize their charging process, so that the battery can quickly absorb electrical energy without damaging its performance and lifespan. This involves multiple aspects of technological innovation and optimization: lithium-ion battery1.Control circuits and management systems-Efficient Battery Management System (BMS): Precisely controls the current and voltage during the charging process, ensuring efficient and safe charging of the battery at all stages.-Intelligent Charging Algorithm: By optimizing the charging curve (such as CC-CV, i.e. constant current constant voltage charging mode), it achieves fast charging at the maximum allowable current of the battery, while avoiding overcharging and overheating.2. Optimization of battery chemical composition-Electrolyte: Develop higher conductivity electrolytes to reduce internal impedance and allow for higher charging currents.-Positive and negative electrode materials: Develo...
