The equalization process of this active equalizer consists of the
following three steps, which are cycled sequentially until the
maximum differential pressure is within the set range:
1. Detecting the largest and smallest monomers;
2. Maximum monomer charging to the super-capacitor of the
equalizer, charging current is the set current, maximum 15A;
3. The super-capacitor of the equalizer discharge to the smallest
monomer, discharging current is the set current, maximum 15A;
4. Repeat steps 1 to 3 until the differential pressure is within
the set range.

APP Installation and Use
APP custom settings:1-15A, because of constant current and constant
voltage technology, The balanced current is independent of the
battery pressure difference.
The APP has Android and IOS version. Password: "123456"
1). IOS users download the APP : Search "Enerkey" in App Store to
download
2). Android users download the APP:“http://www.enerkey.cn/”
download
3). According to the battery type and battery string number, change
the parameters
4). In the APP, you can view the total voltage, average
voltage,naximum voltage difference of the battery pack,and the
voltage and line resistance information of each battery.There is
also an alarm function to detect the equilibriumtemperature, MOS
temperature,and battery pack temperature in real time.
Wiring Diagram
EK-24S15EB supports 2S-24S. The following figure shows how to
install and connect cables to the 24S battery string:
EK-24S15EB supports cascading use, and at least one battery between
every two equalizers is the "common end of energy exchange". The
following uses the 40S as an example to describe how to install and
connect cables:
