AI Technical Summary
Existing walkie-talkie charging methods are inefficient and lack intelligent control, which can easily lead to overcharging or overheating of the battery, potentially causing battery aging or even fire. Long-term full charging or over-discharging will accelerate battery capacity degradation.
It employs an MCU module, a charging module, and a conversion module. It uses a first transistor, a second transistor, and a third transistor to intelligently select the charging power level. Combined with a charging management chip, a voltage divider circuit, and a thermistor, it monitors temperature and voltage in real time and automatically adjusts the charging current to prevent overcharging or high temperature.
It enables fast charging, reduces battery wear, extends battery life, provides multiple safety protections to prevent overcharging, over-discharging, short circuits, and other problems, ensures that the battery works normally in complex electromagnetic environments, and improves system safety and stability.
