Product Description:
The Intelligent Charge and Discharge Equalizer (EK-FD14AS24CK) is a
device designed to balance the charging and discharging of 2~24S
battery packs. It is compatible with NCM/LFP/LTO batteries with
voltages ranging from 2V to 4.5V. The device's actual current
depends on input voltage, line resistance, temperature, and battery
performance, which ensures efficient and accurate charging and
discharging.
Moreover, this Intelligent Charge and Discharge Equalizer supports
automatically identifying the number of connected battery series.
Additionally, it is equipped with various safety measures such as
reverse connection protection, over-temperature protection,
over-voltage protection, and low-voltage protection, ensuring
secure and safe usage.
After balancing is completed, the device stops automatically and
alarms the user. It has three balancing modes: discharge balance,
constant voltage balance, and charge balance. However, to use the
charge balance mode, you'll need an external charger that supports
adjustable non-auto-stop function.
Furthermore, there are two modes of operation available on the
device: automatic identification mode and manual input mode. In the
automatic identification mode, the device identifies the lowest
voltage string and balances all strings to match the voltage of
that string. On the other hand, in the manual input mode, users can
manually set the required balanced voltage, and all batteries will
be balanced accordingly.
The Intelligent Charge and Discharge Equalizer comes with a 7-inch
display that shows various 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.

| 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. |
