Battery active equalizer

EJ-B1A4S

User Manual

1. Overview

Battery Active Equalizer (EJ-B1A4S) is a balanced solution for large-capacity series lithium battery packs Management system.The equalizer uses a supercapacitor as a medium to achieve active energy transfer equalization.

 

The equalizer is suitable for 2 to 24 strings of battery packs with voltage acquisition and equalization. The equalizer works for 1A The equalized current is used for energy transfer, and the equalization current does not depend on the voltage difference of the series connected cells in the battery pack. Voltage acquisition range1 V ~ 5V, accuracy ± 3mV. Applicable to all kinds of batteries on the market such as lithium iron phosphate, ternary lithium, titanic acid, lithium lead acid, etc.

 

The equalizer has Bluetooth communication function and is equipped with mobile APP software. Can be viewed via Bluetooth connected equalizer Single cell voltage, view equalization status, modify setup parameters, etc. Can be applied to small sightseeing cars, scooters,Enjoy battery, battery power, base station backup power, solar power station and other products in the battery PACK, can also be used for batteries

Balance maintenance, repair and other occasions.

 

2. main technical parameters

4. Installation methods and precautions

4.1 Unpacking inspection and precautions

Unpacking inspection and precautions are as follows:

a) Handle the packaging box, equalizer, etc., and try not to invert it;

b) Pay attention to whether the packaging is intact before unpacking, if there is any impact mark, whether it is damaged or not;

c) Take adequate anti-static measures, such as wearing anti-static clothing, wearing anti-static gloves, and wearing an anti-static wrist strap.

After fully discharging, open the antistatic bag and take out the equalizer to check if the equalizer looks good.

4.2 Single equalizer installation

A single EJ-B1A4S equalizer is suitable for battery packs with 2-4 strings of batteries in series. But when the battery pack
