Data acquisition and processing function of li ion battery charger

Data acquisition and processing function of li ion battery charger

The idea of modular design is adopted by the monitoring system, which divided into modules that can be independent of each  other. It can detect the working state of all parts of the combined power system and analyze and process the data, and automatically control the operation of the whole power system. At the same time, the data is sent to the near end monitoring terminal or remote monitoring center through the interface to complete the three remote function and realize the unattended operation. When the system fails, the alarm signal and the buzzer send out the sound and light and the power system is still working out of the li ion battery charger, but the three remote function will be lost, and the backup battery will be in the floating state.

The data acquisition and processing functions of li ion battery charger as below:

I. A AC distribution parts: AC voltage U phase, V phase, w phase; AC current U phase, V phase, w phase; AC contactor working state; main AC joystick switch state, AC lightning arrester state.

II. DC distribution section: DC output voltage, two battery voltage, two battery current, one total load current, load output fuse state, battery fuse state, control two DC circuit breakers.

III. Rectifier: rectifier output current detection, rectifier input / output current limiting state, rectifier switch control, rectifier fan control, rectifier floating charge state control.blow up.

In order to extend the service life of VRLA Li Li battery. It is suggested that the manufacturer increase the 24h self discharge and charging and discharging efficiency in the factory index, so that the floating charging voltage of the unit can be selected correctly.
