DC 6V-60V 30A Battery Charge Discharge Voltage Monitor

Description

The XY-CD63L is a DC 6V-60V 30A Battery Charge Discharge Voltage Monitor. It functions as a discharge protector when the battery is connected to the input terminals and as a charge protector when connected to the output terminals. It supports voltages from DC 6V-60V batteries, where input and output voltages are the same. The device allows setting battery discharge/charge voltages to prevent over-discharging or over-charging, thus protecting the battery from damage. It ensures continuous voltage supply to the load when the battery charging voltage rises to the allowable discharge value, thereby extending battery service life and enhancing safety and reliability.

Set Parameters

Set Work Mode

Keep press 'UP' button for more than 5 seconds to switch between charge and discharge modes.
Discharge mode: Displays the symbol 'OUT'. The battery connects to the input terminal to provide voltage for the load, preventing over-discharging.
Charge mode: Displays the symbol 'IN'. The battery connects to the output terminal and receives voltage from the charger at the input terminal, preventing overcharge.
Tips: It is discharge mode if the battery connects to the input terminal and provides voltage for the load. It is charge mode if the battery connects to the output terminal and needs voltage from the charger.

Set Upper Limit Voltage Value UP

Keep press 'SET' button for more than 5 seconds to enter parameter set mode. User can set UP, dn, OP, dOP, FOP (only for discharge mode).
The default setting is the UP value upon entering set mode. Press 'UP' or 'DOWN' button to adjust the Upper Limit Voltage Value UP.
Press 'SET' to switch parameters, or keep press 'SET' for more than 5 seconds to save and exit set mode if no other settings are needed.
The set value cannot be less than the Lower Limit Voltage Value UP. The system will automatically determine this.
Note: Output stops after entering set mode.

Set Lower Limit Voltage Value dn

Press 'SET' to switch parameters after setting 'UP'.
Press 'UP' or 'DOWN' button to set the Lower Limit Voltage Value dn.
Keep press 'SET' button for more than 5 seconds to save and exit set mode if no other settings are needed.
The set value cannot be greater than the Upper Limit Voltage Value UP. The system will automatically determine this.

Set Discharge/Charge Time OP

This function limits the time the battery can be charged or discharged in either mode.
The set range is '00:00h' to '99:59h'. Setting '00:00h' turns OFF this function.
Press 'SET' to switch parameters after setting 'dn'.
Press 'UP' or 'DOWN' button to set the Discharge/Charge Time OP value.
Keep press 'SET' button for more than 5 seconds to save and exit set mode if no other settings are needed.
The time resets to zero when entering the set mode again.
Example: Set the Discharge/Charge Time OP to '02:00h' in Discharge Mode.
In Discharge Mode, the output will stop after 2 hours of discharge, regardless of whether the battery voltage is lower than the Lower Limit Voltage dn.
Alternatively, the output will stop if the battery voltage drops below the Lower Limit Voltage dn within 2 hours.
At discharge mode: If the Measured Voltage is less than the Lower Limit Voltage Value dn, the LCD displays 'H:ER', indicating an unreasonable time parameter setting. Press any button to stop flashing.
At charge mode: If the Measured Voltage is more than the Upper Limit Voltage Value UP, the LCD displays 'H:ER', indicating an unreasonable time parameter setting. Press any button to stop flashing.

Set Startup Delay dOP

This sets the time interval for the next startup, allowing the battery to rest and cool.
Its set range is 000s-999s. Setting '000h' turns OFF this function.
Press 'SET' to switch parameters after setting 'OP'.
Press 'UP' or 'DOWN' button to set the Startup Delay dOP value.
Keep press 'SET' button for more than 5 seconds to save and exit set mode if no other settings are needed.

Set Forced Startup Time FOP (Only for discharge mode)

This function forces output hold within 0~10s, primarily to prevent voltage drops when the load starts, which could cause misjudgments and stop output.
Its set range is 00s-10s. Setting '00h' turns OFF this function.
Press 'SET' to switch parameters after setting 'dOP'.
Press 'UP' or 'DOWN' button to set the Forced Startup Time FOP value.
Keep press 'SET' button for more than 5 seconds to save and exit set mode if no other settings are needed.

Switch display percentage % and time

Short press the 'UP' button to switch the display between percentage and time.

Query set parameters value

Short press the 'SET' button to cycle through and display UP, dn, OP, dOP, FOP (only for discharge mode) values.

Turn ON/OFF output

Short press the 'DOWN' button. Note: Output can only be turned ON when the battery voltage is higher than the Upper Limit Voltage Value UP.

Turn ON/OFF Sleep Mode L-P

Keep press the 'DOWN' button to turn ON/OFF Sleep Mode L-P.
ON: Turns ON Sleep Mode. The backlight remains on display.
OFF: Turns OFF Sleep Mode. The backlight will turn OFF within 5~10 minutes after no operation. Press any key to restore the backlight.

Function Principle

Example: In Battery discharge mode, the Lower Limit Voltage Value is set to 12V and the Upper Limit Voltage Value is set to 14V.

When power is ON, output voltage is not available if the input voltage is less than 12V.
Output voltage is not available if the input voltage drops below 12V during operation.
Output voltage is not available if the input voltage is between 12V and 14V when power is ON.
Output voltage is available if the input voltage is more than 14V when power is ON.
Output voltage is available until the input voltage drops to 12V during operation.
The input battery needs to be charged to 14V once the battery voltage drops to 12V. Then, the output terminal can provide voltage again.

Discharge Mode OUT

Relay turns ON, and output voltage is provided. The battery starts to discharge when the Battery Voltage is more than the Upper Limit Voltage Value UP. The red indicator turns ON, and the 'OUT' symbol flashes.
Relay turns OFF, and no voltage is output. The battery stops discharging when the Battery Voltage is less than the Lower Limit Voltage Value dn. The red indicator turns OFF, and the 'OUT' symbol is displayed.

Charge Mode IN

Relay turns ON, and the battery starts to charge from the charger when the Battery Voltage is less than the Lower Limit Voltage Value dn. The red indicator turns ON, and the 'IN' symbol flashes.
Relay turns OFF, and the battery stops charging when the Battery Voltage is more than the Upper Limit Voltage Value UP. The red indicator turns OFF, and the 'IN' symbol is displayed.
The display shows 'nbE' if no battery is connected at the output terminal.

Frequently Asked Questions

What is the control voltage range? What is the applicable battery range?

Q: The control voltage range is DC 6V-60V. The applicable battery voltage range is up to 48V, as a 48V battery can reach 60V after full charge.

Why does the relay automatically turn on and off continuously after power on and flashing light?

Q: This occurs if the charging current is too high or the battery capacity is too small, causing the battery voltage to immediately exceed the Lower Limit Voltage 'dn' value, leading to relay OFF. The voltage then drops quickly to the Lower Limit Voltage 'dn' after the relay turns OFF, initiating charging again, creating a cycle. To resolve this, reduce the charging current. Typically, charging current should be 10-15% of the battery capacity (e.g., 2-3A for a 20AH battery). Note that high current charging can cause the battery to overheat, age prematurely, bulge, or even explode.

What control method is used?

Q: This is a voltage control method. For example, if the Lower Limit Voltage 'dn' is set to 12.0V and the Upper Limit Voltage 'UP' is set to 14.5V, the output will close when the voltage reaches 14.5V. The relay will turn ON and begin charging when the voltage drops to 12.0V.

Can it be automatically cycled?

Q: Yes, it can. The voltage control mode manages the turn-off and turn-on cycles.

Can it limit the current?

Q: No, it cannot limit the current. The charging current is entirely dependent on the charger used.

Can I charge a 24V battery by inputting 12V? Or charge a 12V battery by inputting 48V?

Q: This is a simple voltage controller for ON/OFF functions only; it cannot change the output voltage. Therefore, you must prepare a charger with the appropriate voltage for the battery you intend to charge.

Note

This is a charging/discharging controller, not a charger or voltage converter.
Both the monitor and the load consume power from the input terminal battery. Therefore, even when the output voltage is stopped, the monitor continues to consume battery power to monitor the battery voltage.
