Mobile phone chargers are devices used to power mobile phones, with various power supply methods. Below are three of them:
1. AC power supply method: This method is commonly used in household power sockets. The mobile phone charger converts AC power into the required DC power, and then delivers the current to the mobile phone battery.
2. Direct current (DC) power supply method: This method is commonly used in car chargers and electronic devices. DC power supply is the conversion of DC power from vehicle power or other similar devices. Then transport it to the phone battery.
3. Solar power supply method: This method uses solar panels to convert sunlight into electrical energy, and then delivers current to the phone battery. This method is suitable for use outdoors or in sunny areas.
Regardless of the power supply method used, the charging controller of the battery needs to be monitored and managed to ensure the safety of the charging process, while also avoiding battery damage caused by overcharging and excessive discharge.
