XY-L30A battery digital full battery charge control module switches off overcharge protection 6-60V

XY-L30A battery charge control module

  Digital full power-off overcharge protection switch 6-60V

Module highlights:

1. 6-60V lithium batteries can be used;
2. LCD display, battery voltage, charging percentage and charging time 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 and the charger starts to charge the battery; when the battery voltage ≥ the upper limit voltage UP, the relay is turned off to complete an automatic charge;

2. Charging time control function:

   How to turn on the time control function?
   After entering the parameter setting, if the setting parameter OP is not 0, the time control function is turned on. The OP's default parameters are:-: --h, the time control function is not turned on by default;

   After the time control function is turned on (OP is not 0), when the battery voltage is lower than the lower limit voltage dn, the charger starts to charge the battery and the system starts timing; during the timing, when the battery voltage ≥ the upper limit voltage UP, the relay opens; if the battery voltage ＜ Upper limit voltage, but the charging time OP time is up, the relay is off; if OP time is up, the battery voltage is still below the lower limit voltage dn, the relay remains on, the charging time control function is automatically turned off, and H: ER flashes to remind the user that time Parameter setting is not reasonable; press any key to stop flashing;

Note: Time format: 00:59 (00 stands for hour, 59 stands for minute) The maximum time is 99:59, which is 100 hours.

3. Serial port data upload and parameter setting function:
The system supports UART data upload and parameter setting functions (TTL level);
UART: 115200,8,1

Parameter settings

a) By long pressing the SET key, the parameter setting interface is entered, and the LCD will display SET;

b) After entering the parameter setting interface, press the SET key to switch the set parameters;

c) After the parameter is selected, it can be set by UP / DOWN keys, and supports short and long press (fast increase or decrease);

d) If you want to set other parameters, repeat steps b), c);

e) After setting all parameters, press and hold the SET button to exit and save;

Third, the key 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 the charging percentage and the charging time;

Short press the DOWN button to select the on / off relay enable. If the relay enable is off, ‘OFF' will be displayed as a reminder and the relay will be disconnected;

Long press the UP button to set the state of the LCD backlight (L-P), OFF: the backlight is always on, on: the backlight automatically goes off after 5-10 minutes;

Long press SET button to enter parameter setting.

Fourth, the calculation of voltage percentage: battery voltage / (upper limit voltage-lower limit voltage).

Five, additional functions

a) Charging time recording function: When charging time control is not turned on, the product will record the complete time once. When entering the time display interface, the charging time will flash and display; then exit the time display interface or clear the next time the charging is turned on (relay is turned on). ;

b) Automatic parameter detection: When the parameters are set and exited, if the voltage lower limit dn ≥ upper limit voltage is up, the system will flash “ERR” as a reminder;

c) Battery access detection: This product is attached to the battery. If the battery is not connected, the system will display "nbE" on the bottom line as a reminder;

Six, common failure analysis

Q: How much V level is suitable for use? How much V is this module suitable for?

Answer: This section is suitable for use in the minimum 6V and maximum 60V voltage range, the maximum expenditure level is 48V, because the 48V battery is fully charged at about 60V, and then burns up if it is higher. If your battery is higher than 48V, please choose another.

Q: The relay crackles after power on! The light is blinking?

Answer: This is because your charging current is too large or the battery capacity is too small. As soon as the power is turned on, the upper limit of the voltage is reached immediately. After the relay is disconnected, the voltage quickly drops to the lower limit of the voltage and starts charging again. This cycle is repeated. You only need to reduce the charging current, usually the charging current is 1 to 1.5 times the battery capacity, such as 20AH battery charging current is generally around 2-3A! Note that high current charging will cause the battery to heat up and accelerate aging, bulging and even explosion!

Q: What control method? Can I cycle charging automatically? Can I charge while using? Can current be limited?

Answer: This is voltage control. For example, the lower voltage limit is set to 12.0V, the upper voltage limit is 14.5V, the voltage is charged to 14.5V and the power is turned off. The voltage is reduced to 12.0V and the relay is closed to start charging. You can charge while using. Voltage control The method only plays a role of turning off and on. It cannot limit the current. The charging current depends entirely on your charger!

Q: Can 12V battery be charged by inputting 12V, or can 12V battery be charged by inputting 48V?

Answer: This section is a simple voltage controller that only serves as a switch. It cannot change the voltage to charge the battery, so you must prepare what kind of charger you need to charge any battery! necessary!
