4.9 Shared Power Supply
Leiditech recommends shared power protection devices and solutions
The shared power supply includes an MCU microcontroller inside the cabinet, which can read and store data, issue commands, and other functions; The WIFI module is mainly responsible for receiving signals. The temperature sensor is responsible for detecting whether the temperature of the charging bank in the cabinet is normal, and the LCD display screen can play advertisements. The shared power supply has two power packs, which can accommodate up to 12 power packs.
Shared power banks will achieve rapid expansion in the next three years, but their profit model and user experience will be key factors in the competition in the shared power bank market. Pinion batteries have become a commonly used technology for portable applications using rechargeable batteries due to their advantages such as high energy density, high voltage, low self discharge rate, and no memory effect. To achieve safe work, temperature monitoring of shared power sources is particularly important.
