Product Description: 24S 14A Intelligent Charge and Discharge
Equalizer (EK-FD14AS24CK)
The 24S 14A Intelligent Charge and Discharge Equalizer
(EK-FD14AS24CK) is designed for use with a 2~24S battery pack that
uses NCM / LFP/LTO (Li-ion/Lifepo4/Lto) technology, with a battery
voltage between 2V and 4.5V. Please note that the actual current
will depend on the input voltage, line resistance, temperature, and
battery performance.
The intelligent equalizer supports automatic identification of the
number of battery series. Additionally, it comes with built-in
reverse connection protection, over-temperature protection,
over-voltage (4.5V) protection, low-voltage (2V) protection, and
alarm. Once the balancing process is complete, the equalizer will
automatically stop and sound an alarm.
The device provides three types of balancing methods: discharge
balance, constant voltage balance, and charge balance. Please note
that if you wish to use the charge balance feature, you would need
an external charger with adjustable non-auto-stop function.
The device comes with two modes: automatic identification mode,
which is based on the lowest voltage string and will balance all
cells to the voltage of the lowest voltage string, and manual input
mode, which allows you to set the required balanced voltage for all
cells.
The product also includes a 7-inch display that shows 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 Measurement
The voltage measure range is between 1V and 4.5V. The accuracy of
voltage measure is ±(0.08%+0.06%FS).
Current Setting
The current setting range is from 0.1A to 14A, which can be
adjusted according to your needs.
Discharge Balance
This product uses the PWM pulse discharge method for discharge
balance.
Charging Assistance
An external charger is required for charging assistance. The
charging port can withstand a voltage of ±DC130V.
Equilibrium Voltage
The equilibrium voltage is automatically identified.
Interface Voltage
The interface can withstand a voltage from B- to B24 without
voltage, ranging from -120V to +120V.
Power Supply
The power supply of this product 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. |
