The Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK) is a key component for 2~24S battery packs, which can be used for NCM/LFP/LTO batteries with voltage ranging from 2V to 4.5V. This device is designed to balance the voltage of each battery in the pack and ensure their safety and longevity. The actual current of the device varies depending on input voltage, line resistance, temperature, and battery performance.
The Charge and Discharge Equalizer also supports automatic identification of the number of battery series, and has various safety features such as reverse connection protection, over-temperature protection, over-voltage (4.5V) protection, low-voltage (2V) protection, and alarm. Once the balancing process is completed, the equalizer automatically stops and alarms.
There are three different modes: discharge balance, constant voltage balance, and charge balance. However, an external charger with an adjustable non-auto-stop function is required for charging.
The Equalizer uses two modes: automatic identification mode and manual input mode. In automatic identification mode, the lowest voltage string is used as the base, and the voltage of all strings is balanced to the lowest voltage string (voltage is aligned downward). Manual input mode allows users to set the required balanced voltage value, and the device balances all strings to this set voltage value.
This Intelligent Charge and Discharge Equalizer also comes with a 7-inch display that shows important information such as balanced voltage, balanced current, voltage per string, total voltage, maximum voltage, minimum voltage, average voltage, maximum voltage difference, number of battery strings, and temperature.
Voltage Measure Range: The range for voltage measurement is from 1V to 4.5V.
Voltage Measure Accuracy: The accuracy for voltage measurement is ±(0.08%+0.06%FS).
Current Setting Range: The range for current setting is from 0.1A to 14A, and it can be adjusted.
Discharge Balance Method: The method used for discharge balance is PWM pulse discharge method.
Charging Assistance: In order to charge, an external charger is required. The charging port is able to withstand a voltage of ±DC130V.
Equilibrium Voltage: The equilibrium voltage is automatically identified.
Interface Withstand Voltage: The interface is able to withstand a voltage of B- to B24 without voltage, ranging from -120V to +120V.
Power Supply: The power supply required is DC12V5A.

| Balanced voltage mode | There are two modes: automatic identification mode and manual input mode. The automatic identification mode is based on the lowest voltage string, and all are balanced to the voltage of the lowest voltage string (voltage is aligned downward). The manual input mode is to set the required balanced voltage, and all are balanced to the set voltage value. |
| Optimum charger voltage | Optimal charger voltage (V) = (balance voltage (V) * number of strings) + (number of strings * 0.01V); Charger current is less than or equal to the balance current. Charging current is less than or equal to 10A. Exceeding 12A will damage the device. When charging balance, please disconnect the charger immediately after balance is completed. |
| Display content | Balanced voltage, balanced current, voltage per string, total voltage, maximum voltage, minimum voltage, average voltage, maximum voltage difference, number of battery strings, temperature |
| Operation Instructions | After power on, the default mode is automatic identification. After connecting the wire, press the "Start" button or the "Equilibrium" button on the chassis to automatically identify and start balancing. Manual input mode, press "Manual input" to enter manual input mode,Then press "Equilibrium Voltage (V)" to open the numeric keypad and enter the balance voltage (2.0v-4.5v) to confirm, then press the "Start" button or the "Equilibrium"button on the chassis to start balancing. Press "Maximum Balance Current (A)" to enter the current setting, the range is 0A-14A. |
