• Supports two modes: charge & discharge balance and discharge balance.
• High-precision voltage acquisition module for safe and precise balancing control.
• Each battery cell is wired separately and independently, effectively avoiding connection errors.
• Safety Protections: Overvoltage, undervoltage, overcurrent, output short circuit, reverse connection, overtemperature, etc.
• Software Upgrade: Used for software upgrade, including App upgrade and Firmware upgrade.

The EVB624 is used for balancing the internal cells of battery packs. When detecting significant voltage variance or inconsistent cell voltages among cells within battery packs, use the EVB624 to address the issue of excessive voltage variance. Once the cells inside the battery module are replaced, the EVB624 is widely used to balance the cells, ensuring that the voltage levels of individual cells are uniform.

EVB624 Battery Pack Module Wireless Equaliser is a split equalization maintenance device developed by Launch, which is designed based on the charge and discharge characteristics of lithium batteries. It can effectively repair the problem of battery performance degradation, which caused by excessive pressure difference of single battery. The charger and wireless discharge module of the equaliser use split design, which are communicated through wireless networking, and maximum configuration 6
wireless discharge modules (24 channels). The 10.1-inch touch screen is easy to operate and visualizes information of battery, such as voltage, current, status, capacity,etc. The wireless equaliser supports three modes: equilibrium, discharge and charge, it can automatically save historical equilibrium data records and supports data USB disk export. Suitable for lithium iron phosphate, ternary lithium, Lithium manganate and other common lithium battery type.

Launch EVB624 Features:

• Separate charge/discharge design with flexible equalization channels combination for up to 24 cells.
• Wireless networking for easy extension of channel numbers.
• Compatible with most common Lithium battery types.
• Supports both charge and discharge equalizing modes.
• Isolated, high-precision voltage acquisition for secure and accurate equalizing control.
• Independent cell wiring to prevent connection errors.
• Patented clamp design for efficient and reliable connection.

Launch EVB624 Function:
Equalizing Maintenance
Supports discharge and charge-discharge equalizing modes, capable of maintaining batteries such as NMC, LiFePO4 and LMO batteries.

Data Analysis
Automatically saves historical equalization records and supports display in curve and bar chart formats.

Data Transfer
Allows for export of historical data to a USB flash drive in Excel file format.

Multiple Protections
Provides safety protections against overvoltage, undervoltage, overcurrent, output short circuit, reverse polarity, and overtemperature.


Launch EVB624 Device Connection
Step1: First, connect the plug of DC high-voltage output cable into the high-voltage output port of the charger, and then connect the positive and negative output cable of DC high-voltage cable to the positive and negative terminals of the battery pack respectively (the red cable is the positive, the black cable is the negative).
Step2: Connecting one end of the AC power cord to the power supply port of the charger and the other end to AC power.
Step3: The device turns on when closed the AC breaker.
Step4: Long press the power button on the back of the wireless discharge module to turn it on, double press the power button and enter the networking mode when the blue light blinks to pair with the charger.
Step5:
1) Connect the connector end of equalizer test cable to the channel #1 of the discharge, the other end of equalizer test cable are connected to the positive and negative of the battery cell respectively (the red clip is the positive cable, the black clip is the negative cable).The light indicator above the channel #1 is on, it means that the positive and negative poles are connected correctly. If the light is not on, it means that the positive and negative poles are connected incorrectly. Check whether the battery cell is normal on the charger screen after correctly connected. If the voltage is normal, then connecting the channel #2/3/4 in turn.
2) Then connect the connector end of temperature acquisition cable to the temperature port, and the probe end of temperature acquisition cable is connected to the corresponding battery packs.
3) And follow steps1) and 2) to connect the other wireless discharge module until all battery cells are connected.
4) If the cell voltage is unnormal during connection, you need to troubleshoot whether the cell or connecting wire is normal firstly.
Step6: Setting the equilibrium/discharge parameters to start the equilibrium/discharge test.
