XY-L30A battery battery charging control module
Digital full power off and overcharge protection switch 6-60V
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:
