storage battery charge-discharge device

Range of application:
Suitable for charge, discharge battery , measurement of various lead-acid battery and alkaline battery
Working Principle:
The device adopt advanced double closed loops PID feedback control technology, to commutate toward working voltage and current of charge and discharge machine
MIcro controller give voltage and curent signals according to program set and calculate compare with DC side voltage and current signal that close loop system feedback
By regulating circuit, it controls touching pulse output by phase shift chip to arouse thyristor to commutate as well as change electricity charge and discharge by contactor.
When the machine is on work, system can timely feedback voltage and current signals of DC side. one hand, comparing to set point it automatically regulate to make set point keep accordance with voltage/current parameters, another hand, it transmit these signals to micro controller and display the actual numbers timely on the LCD board by calculation
Performance and characteristic
Energy saving: adopting active contravariant to feed back energy of battery into power network when it discharge , so the energy loss will be greatly reduced
Practicability; several modes of charging and discharging. It automatically change for different section by time, power capacity ,voltage.
Safety: Complete protection function for both software and hardware. also had malfunction protection of over/lower voltage, current cut, over/lower current, over heat
Micro-computer control, Host computer contorl system, Power off protection function, Data collection, Date-processing, Stable performance
Scheme drawing:
1) hardware frame drawing
2. monitor software
Each monitor machine may monitor 128 loops at most and regulate the loop mumbers of software monitor according to actual parts conditions.
Main function of soeware:
Timely monitor the working parameters of every loop in machine of prsent system, display in the window mudule of each loop and provide timely the malfunction alert
control and operation: operate on single loop or multi-loops a the same time.
Record image analysis of date, export data and print
