Product Description:
The Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK) is designed for 2~24S battery pack with NCM/LFP/LTO (Li-ion/Lifepo4/Lto) and battery voltage between 2V and 4.5V. The actual current is influenced by input voltage, line resistance, temperature, and battery performance. This device has the capability to automatically identify the number of battery series, and provides reverse connection protection, over-temperature protection, over-voltage (4.5V) protection, low-voltage (2V) protection, and alarm.
With the function of discharge balance, constant voltage balance, and charge balance, this device needs an external charger with adjustable non-auto-stop function. Two modes are available: automatic identification mode and manual input mode. In automatic identification mode, the device is based on the lowest voltage string and all are balanced to the voltage of the lowest voltage string (voltage is aligned downward). In manual input mode, the required balanced voltage is set and all are balanced to the set voltage value.
Moreover, this device is equipped with a 7-inch display that provides 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.
Technical Parameters:
Voltage Measure Range
The voltage measure range for this device is between 1V to 4.5V. This means that the device can accurately measure voltage ranging between these values.
Voltage Measure Accuracy
The voltage measure accuracy for this device is ±(0.08%+0.06%FS). This means that there is a level of accuracy it can achieve when measuring voltage within its range.
Current Setting Range
This device has a current setting range between 0.1A to 14A which can be adjusted to suit specific needs. This adjustable range gives the user flexibility in utilizing the device.
Discharge Balance Method
The discharge balance method used in this device is the PWM pulse discharge method. The PWM method allows for an efficient and controlled discharge of the the device.
Charging Assistance
To use this device, an external charger is required. The charging port has been designed to withstand voltage up to ±DC130V.
Equilibrium Voltage
The device has an automatic identification equilibrium voltage feature which makes the monitoring and balancing of the energy levels more efficient.
Interface Withstand Voltage
The interface withstand voltage/B- to B24 without voltage is -120V~+120V. This means that the device has a certain level of tolerance to withstand voltage variances within this range.
Power Supply
The device runs on an external power supply of DC12V5A which is required for it to work as intended.

| 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. |
