4. Tatūnga me te Tāuta
The following steps outline the installation and wiring process for the DALY Smart BMS. Always ensure power is disconnected from the battery pack and any connected loads before beginning installation to prevent electrical hazards.
A clear wiring diagram illustrating the three-step installation process for the DALY K series BMS, demonstrating connections for the overall positive electrode (B+), overall negative electrode (B-), sampling cables for individual battery strings, and connections to the electric machine, load, and recharger.
Nga Waea Waea:
- Hipanga 1: Hononga SampNgā Taura Ling. The first black cable in the sampling cable set connects to the negative terminal of the battery. The subsequent red cables connect to the positive terminal of each battery string sequentially (e.g., second red cable to the positive terminal of the first string, third red cable to the positive terminal of the second string, and so on). Continue this pattern until all sampling cables are connected to their respective positive terminals.
- Hipanga 2: Tirohia ngā Taura. After connecting all sampling cables, use a multimeter to measure the voltage between two adjacent cells, starting from the header. Ensure that the voltage readings are consistent and that there are no wrong connections or missing connections.
- Hipanga 3: Honoa ngā Waea Putanga. Connect the B- wire of the BMS to the total negative terminal of the battery pack. Then, carefully plug the sampling cable into the designated port on the BMS. After activating the BMS, verify that the total battery voltage measured between B+ and B- matches the voltage measured between P+ and P- (the charge/discharge terminals).
5. Mahi
The DALY Smart BMS can be monitored and controlled via a dedicated smartphone application and a Cloud Manager platform, providing comprehensive oversight of your battery system.
Smartphone App Monitoring:
With the integrated WiFi module, you can remotely monitor your lithium batteries through the Internet using the "SMART BMS" smartphone app. The app allows you to view and set various battery parameters, including State of Charge (SOC), voltage, electric current, temperature, and cycle number.
