Product Description:
The Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK) from
24S 14A is designed to be compatible with 2~24S battery packs. It
works with NCM, LFP and LTO batteries i.e. Li-ion, Lifepo4, and Lto
batteries. The battery voltage should range between 2V and 4.5V.
The actual current of the equalizer is influenced by different
factors such as the input voltage, line resistance, temperature,
and battery performance. The product works to support automatic
identification of battery series and features several protective
functions such as reverse connection protection, over-temperature
protection, over-voltage (4.5V) protection, low-voltage (2V)
protection, and alarm.
Upon completion of the balancing process, the intelligent equalizer
stops operations and signals an alarm. It has three balancing
modes: discharge balance, constant voltage balance, and charge
balance. However, an external charger with adjustable non-auto-stop
function is required to use this feature.
The product offers two modes: automatic identification mode and
manual input mode. In the automatic identification mode, the lowest
voltage string is the reference point, and all the batteries are
balanced to the lowest voltage string's voltage. For the manual
input mode, you can set a required balanced voltage, and all
battery strings are balanced to the set voltage value.
The Intelligent Charge and Discharge Equalizer also comes with a
7-inch display that shows data 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 and Current Measurement System Specifications
The voltage measure range for this system is 1V to 4.5V.
Additionally, the voltage measure accuracy is ±(0.08%+0.06%FS).
When it comes to current setting, the range is 0.1A to 14A. This
setting is adjustable according to your needs.
The system also features a PWM pulse discharge method for discharge
balance.
If you need to use an external charger, the charging port can
withstand voltage ±DC130V. Moreover, the equilibrium voltage is
automatically identified in this system.
When it comes to interface withstand voltage, the range from B- to
B24 without voltage is -120V to +120V. Finally, the power supply
for this system 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. |
