Product Description:
Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK)
The EK-FD14AS24CK is a 24S 14A equalizer designed for NCM, LFP, and
LTO batteries, specifically for Li-ion, Lifepo4, and Lto battery
types. This equalizer supports a battery voltage range between 2V
and 4.5V, and the actual current is determined by input voltage,
line resistance, temperature, and battery performance. With this
equalizer, you don't need to worry about identifying the number of
battery series, as it supports automatic identification.
The EK-FD14AS24CK is equipped with various protection measures,
including 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 sets off an alarm.
The EK-FD14AS24CK supports three different types of balance:
discharge balance, constant voltage balance, and charge balance.
However, to utilize the charge balance, you'll need an external
charger that has adjustable non-auto-stop function.
You can choose between two modes for this equalizer: automatic
identification mode and manual input mode. In automatic
identification mode, the lowest voltage string is used to balance
all the strings to the same voltage (voltage is aligned downward).
In manual input mode, you can set the required balanced voltage and
the equalizer will balance all strings to the set voltage.
The EK-FD14AS24CK comes with 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 and Current Setting
The voltage measure range of this device is between 1V and 4.5V,
and the accuracy of the voltage measure is ±(0.08%+0.06%FS). The
current setting range varies between 0.1A to 14A and can be
adjusted.
Discharge Balance and Charging Assistance
The discharge balance method utilized for this device is the PWM
pulse discharge method. If you require charging assistance, you
will need to use an external charger. The charging port on this
device can withstand voltage ±DC130V.
Equilibrium Voltage and Interface Voltage
This device has an automatic identification equilibrium voltage
feature. Additionally, the interface withstand voltage ranges from
B- to B24 without voltage -120V~+120V.
Power Supply
The power supply for this device 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. |
