How to choose DALY active equalizing BMS
1.Download the communication software (APP SMART BMS on the mobile phone, computer -side upper machine software), and set the capacity (AH) of the battery pack to the correct capacity.
2.Search for "Smart BMS"in the mobile phone application market, download and install. (If you can't download it, please contact the store customer service).
3. After installing the APP, turn on the positioning and Bluetooth function of the
4.Open the APP, you can see the Bluetooth serial number (consistent with the serial number on the physical object of Bluetooth) in the first interface, click Bluetooth Enter the APP to enter the actual capacity of your own battery pack (XXAH), click the settings, enter the password 123456, the refresh capacity will be updated to the capacity you just entered.
5.After the capacity is set, the battery pack can be charged, the charging triggers the second -level overcharge protection, and the SOC will be automatically calibrated to 100%.
Remarks: The SOC adopts the ampere-hour integration algorithm, and the accuracy of the actual capacity of the battery pack will make the SOC accurate. In the parameter setting interface, incorrect parameter setting will cause the product to not be used normally. Customers can modify "protection parameters" and "temperature protection" according to their needs.
Sensitive Detection Intelligently Balanced At All Times
It will not be restricted by battery charging, discharging, static, dormant state, etc. Once the cell voltage triggers the active equalization, it can automatically start power transmission until voltage equalizing.
Equalization of Power Transfer
Transfer power with O~1A current, non-internal resistance energy dissipation equalization and low heating, can be connected to the battery pack for a long time.
Take a 4 strings battery pack as an example
After active equalization
Balanced current is 0.6A. The effects before and after equalization are as follows:
Guarantee safety and delay deterioration
In the process of over-charge, over-discharge, over-current, short-circuit, and over-temperature protection, at the same time, fine actively prevent premature deterioration of individual cells, so as to make the overall battery pack stronger and more stable.
Smart Communication Real Time Monitoring
support communication protocol of UART and RS485,Can also connect to Mobile Phone with Bluetooth APP and computer with USB Cable, Real time monitor and set up all the battery information.
Strong adaptability convenient assembly
The DALY Smart equalizer comes with free 18AWG cable to accurately gather voltage data, can be easily connected with battery packs and smart active equalizing BMS (both BMS and Active equalizer ),terminal studs of Active equalizer and BMS are interconvertible.
More Accessories To Choose
Lithium standard is widely used
Suitable for Li-ion and LiFePo4 battery pack, simple plug can balance and protect each cell.
Product Specifications (BMS)
Suitable for Li-ion/LifePO4.
Remarks: Size (width*length*thickness)
The parameters of smart BMS can be adjusted (under professional guidance)
Product parameters (Equalizer)
Different brands of active equalizer have different wiring, so matching wiring must be used.
Connection sequence of BMS to battery:
※ Special note: Wires from different manufacturers is not universal, please make sure to use matching wires; B- and P- lines of different manufacturers have different colors. Please pay attention to the B- and P- marks.
1.Remember!! Do not insert BMS when welding the sampling wire.
2.The wiring starts from the thin black wire connecting the total negative terminal (B-),and the second wire (red line) is connected to the positive terminal of the first string of batteries, followed by the positive terminal of each string of batteries until the last string of total positive terminal (B+).
3.Do not directly insert the plug into BMS after the cable is connected,first measure the voltage between each two adjacent metal terminals on the back of the plug. The Li-ion battery voltage should be between 3.0~4.15V,LiFePo4 battery should be between 2.5~3.6V, LTO battery should be be-tween 1.8~2.8V, ensure the voltage is correct before the next operation.
4.Connect the B-wire of BMS (thick blue line) to the total negative pole of the battery(b-wire length should not exceed 40cm).
5.Insert the cable into BMS.
After wiring is completed:
1.Measure the battery B+ to B-voltage and B+ to P- voltage is equal(that is battery itself voltage and through BMS voltage is equal. The equal voltage proves that the protection plate works normally. If not, please check again according to the above wiring sequence.)
2.The positive terminals of charge and discharge terminals are directly connected to the total positive terminal (B+) of the battery. The connection mode of the common port BMS is that the negative electrode of charge and discharge is connected to the P-of BMS. The connection mode of the separate port BMS is that the negative pole of charging is connected at C-,and the negative pole of discharging is connected at P-.
Hardware active equalizer connection method
※ Special note: The active equalizer should match BMS with the same strings, and cannot be mixed in different strings.
1.Check and confirm all connection wires are welded correctly after BMS as-sembly is completed;
2.The wiring plug corresponds to the BMS plug and active equalizer plug. BMS plug and active equalizer plug can be used without distinction. Before starting BMS,ensure that the equalizing is properly connected and BMS is securely fixed to the cell. Before connecting BMS, ensure that the connection is correct. Otherwise, BMS may work abnormally or even burn down.
Finally, if you have any questions, please contact customer service to help you solve.
