The working principle of mobile power supply
Mobile power supply is a portable charging device that can provide power for various electronic devices such as mobile phones, tablets, Bluetooth earphones, etc. It is usually composed of lithium batteries and has charging and discharging functions. Below, we will provide a detailed introduction to the working principle of mobile power supplies.
1. Charging principle of lithium batteries
Mobile power supplies typically use lithium batteries as power storage units. Lithium batteries are a type of chemical battery that converts electrical energy into chemical energy through chemical reactions for storage. When charging, the external power supply is connected to the mobile power supply through a charging cable, and the current flows through the battery, converting electrical energy into chemical energy and storing it in the battery.
2. Charging protection circuit
The mobile power supply is equipped with a charging protection circuit inside, which is used to monitor and control parameters such as current, voltage, and temperature during the charging process. The charging protection circuit can automatically cut off the charging current to prevent overcharging and discharging, thereby extending the battery life and protecting the safety of the equipment.
3. Charging control chip
The charging process of the mobile power supply is controlled by the charging control chip. The charging control chip can adjust the charging current and voltage based on the battery status and external power supply voltage and current information to achieve the best charging effect. It can also monitor the charging status and automatically stop charging when the battery is fully charged, avoiding overcharging.
4. Battery management system
The mobile power supply is also equipped with a battery management system to monitor the status and performance of the battery. The battery management system can monitor real-time information such as battery level, temperature, voltage, etc., and protect and manage the battery based on this information. It can provide a display of the remaining battery capacity, allowing users to have a clear understanding of the battery's usage.
5. Output circuit
The output circuit of a mobile power supply is used to convert stored electrical energy into direct current for use by external devices. The output circuit usually includes a DC to DC converter and a voltage regulator circuit. The DC to DC converter converts the direct current provided by the battery into the voltage and current required by external devices. The voltage stabilizing circuit can maintain the stability of the output voltage and prevent voltage fluctuations caused by load changes.
6. Output protection circuit
The mobile power supply is also equipped with output protection circuits to protect external devices from issues such as overcurrent, overvoltage, and short circuits. The output protection circuit can automatically cut off the output circuit to protect the safety of external devices.
7. Charging and discharging efficiency
The charging and discharging efficiency of mobile power sources is an important indicator to measure their performance. Charging efficiency refers to the proportion of electrical energy from external power sources converted into chemical energy from batteries, usually above 80%. Discharge efficiency refers to the proportion of chemical energy in a battery that is converted into electrical energy required by external devices, usually above 90%.
Summary:
Mobile power supply is a portable charging device, which mainly involves the charging and discharging process of lithium batteries, charging protection circuits, charging control chips, battery management systems, output circuits, and output protection circuits. Through the collaborative work of these components, mobile power can provide reliable power support for various electronic devices. When choosing a mobile power supply, we can pay attention to its charging and discharging efficiency, as well as safety protection functions and other factors.
