Product Overview
Modularized Wireless Equalizer 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 modularized wireless equalizer uses split design, EVB624 and EVB624-D are wirelessly networked, and can achieve simultaneous equalization of up to 24 channels (1pc EVB624 with 6pcs EVB624-D). 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: charge and discharge equalization, discharge equalization, and charge equalization, 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.

EVB624-D:
Device Connection
Step1: First, connect the plug of DC high-voltage output cable into the high-voltage output port of the EVB624, 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 EVB624 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 EVB624-D to turn it on, double press the power button and enter the networking mode when the blue light blinks to pair with the EVB624.
Step5:
- Connect the connector end of equalizer test cable to the channel #1 of the EVB624-D, 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 EVB624 screen after correctly connected. If the voltage is normal, then connecting the channel #2/3/4 in turn.
- 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.
- And follow steps 1 and 2 to connect the other EVB624-D until all battery cells are connected.
- If the cell voltage is unnormal during connection, you need to troubleshoot whether the cell or connecting wire is normal firstly.
Step6: Setting the charge and discharge equalization, discharge equalization, and charge equalization parameters to start the charge and discharge equalization, discharge equalization, and charge equalization test.
