Instruction
1. 6-60V any battery, lithium battery can be used;
2. Liquid crystal display, battery voltage, charging percentage and charging time are clear at a glance;
3. The function is very powerful, it can automatically charge control, can control the charging time, can set and upload the corresponding parameters through the serial port;
1. Automatic charging control function:
By setting the upper limit voltage UP and the lower limit voltage dn ; when the battery voltage ≤ the lower limit voltage dn , the relay is turned on, the charger starts to charge the battery; when the battery voltage ≥ the upper limit voltage UP , the relay is turned off, and an automatic charging is completed;
2. Charging time control function:
How to turn on time control?
After entering the parameter setting, the setting parameter OP is not 0 , then the time control function is enabled. The default parameter of the OP is: — : –h , the time control function is not enabled by default;
After the time control function is turned on ( OP is not 0 ), when the battery voltage < lower limit voltage dn , the charger starts to charge the battery, and the system starts timing; during the timing, the battery voltage ≥ the upper limit voltage UP , the relay is turned off; if the battery voltage <Upper voltage, but the charging time OP time is up, the relay is off; if the OP time is up, the battery voltage is still <lower limit voltage dn , the relay remains on, the charging time control function is automatically turned off, and the H:ER flashes to remind the user, time The parameter setting is unreasonable; press any key to stop flashing;
Note: Time format: 00:59 ( 00 for hours, 59 for minutes) The maximum time is 99:59 , which is 100 hours.
3. Serial data upload and parameter setting function:
The system supports UART data upload and parameter setting function ( TTL level).
Data upload message format
Battery voltage + battery percentage + charging time + charging status 12.0V, 020%, 00:10, OP
Second, the parameter settings
a) by a long press SET key to enter the parameter setting screen, liquid crystal displays SET ;
b) After entering the parameter setting interface , switch the set parameters by short pressing the SET button;
c) After selecting the parameters, you can use the UP/DOWN button to set, support short press, long press (rapid increase or decrease);
d) Repeat steps b) , c) if you want to set other parameters ;
e) After all the parameters are set, press and hold the SET button to exit and save;
Third, the button function description
In the running interface (main interface),
Short press the SET button to display the currently set parameters;
Short press the UP button to switch between display charging percentage and charging time;
Short press the DOWN button to select the enable / disable relay enable. If the relay is enabled to turn off, it will display ‘OFF’ to remind you that the relay is off.
Press and hold the UP button to set the status of the LCD backlight ( LP ), OFF : the backlight is always on , on : the backlight is automatically turned off after 5-10 minutes;
Press and hold the SET button to enter the parameter settings.
Fourth, the calculation of the voltage percentage: battery voltage / (upper limit voltage – lower limit voltage).
Five, additional features
a) Charging time record: unopened charging time control case, the product will record a full time, when entering the time display interface, blinking charging time; then exit time display primary charging interface or the opening ( the relay is turned on ) emptying time ;
b) Automatic parameter detection: When the parameter is set, when exiting, if the voltage lower limit dn ≥ upper limit voltage up , the system will flash “ ERR ” to indicate the alarm;
c) Battery access detection: This product is attached to the battery. If the battery is not connected, the system will display “ nbE ” on the lower line to remind you;
