This equalizer is suitable for 2S to 24S battery strings and provides voltage collection and balancing functions. The equalizer operates in a continuous manner

 

The equalizing current of 15A is used for energy transfer. The equalizing current does not depend on the voltage difference of the battery cells in series in the battery pack. Voltage acquisition range 1.5V~4.5V, precision 1mV. Suitable for the market mainstream lithium ternary, lithium iron phosphate, lithium titanate battery.

 

This equalization instrument has Bluetooth communication function, and supporting mobile phone APP software. It can be checked by connecting to the equalizer via Bluetooth Check the battery voltage, balance status, and set parameters.

 

It can be used in small sightseeing vehicles, mobility scooters, shared cars, high-power energy storage, base station backup power supply, solar power station, etc battery PACK, can also be used for battery balance maintenance, repair and other occasions.

 

• 1. This module is a time sharing single channel transfer current that is independent of the volt-age difference,
• 2. Even if the voltage difference is reduced to 1mV, the current can still maintain a maximum of4A.
• 3.24-hour uninterrupted overall balance
• 4. Relying on internal energy transfer of the battery to achieve overall balance.
• 5. Ultra low loss
•

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:
