4. Водич за инсталација

Follow these steps carefully to install your DALY Smart BMS. For visual guidance, refer to the installation video below.

4.1. Battery Preparation

1. Identify the total positive terminal (B+) and total negative terminal (B-) of your battery pack.
2. Ensure all individual cells are properly connected in series.

4.2. Сampling Cable Connection

The metal ring terminals for the sampling cables are user-supplied.

1. Connect the first black cable (B-) and the blue B- wire from the sampповрзете го кабелот до вкупниот негативен терминал на батеријата.
2. Connect the remaining sampling cables in order, from B1 to B+ (or B8 for an 8S pack), to the positive terminals of each cell.
3. Внимание: If using fewer series than the maximum supported by the BMS, do not short-circuit the excess wires. Instead, securely tape them up with insulation tape to prevent accidental contact.
4. Connect the B+ wire (red) from the sampling cable to the total positive terminal of the battery pack.

4.3. Верификација на ожичување

Before connecting the sampling cable to the BMS, verify the wiring using a multimeter:

1. Place the black probe of the multimeter on B0 (the first pin of the sampling cable, connected to the total negative terminal).
2. Place the red probe on B1, then B2, B3, and so on, sequentially.
3. Observe the multimeter readings. If the multimeter displays positive voltage readings that increase step by step (approximately 3-4V per step for typical lithium cells), the wiring is correct.
4. Важно: During this testing, do not let the two multimeter probes touch each other, as this may cause a short circuit in the cable.

4.4. Поврзување со BMS

1. Connect the main B- wire from the battery pack to the B- terminal on the BMS.
2. Insert the temperature sensor (NTC) into the designated NTC port on the BMS.
3. Carefully plug the sampling cable connector into the corresponding port on the BMS.
4. Connect the main B+ wire from the battery pack to the B+ terminal on the BMS.
5. Once all connections are secure, check the BMS. If the green light on the BMS is illuminated, the BMS is working properly.

8. Одржување и решавање проблеми

8.1. Општо одржување

• Regularly check all cable connections for tightness and corrosion.
• Одржувајте ја BMS единицата чиста и без прашина и влага.
• Мониторирање на волуменот на батеријатаtages and temperatures via the "BalanceBMS" app to ensure optimal performance.

8.2 Смена на проблеми

Доколку наидете на проблеми, разгледајте го следново:

• BMS не се вклучува: Verify all power connections (B- and B+ main wires) and ensure the sampling cable is correctly plugged in. Check the green indicator light on the BMS.
• Неточно томtagд Читања: Re-check the sampling cable connections to each cell and ensure they are in the correct sequence. Use a multimeter to verify individual cell voltages as described in the installation section.
• Проблеми со балансирање: Ensure the active balancer is enabled in the app settings. Check for significant voltage differences between cells that might indicate a faulty cell or connection.
• Проблеми со комуникацијата: Ensure Bluetooth is enabled on your device and the BMS. For RS485/CAN, verify cable connections and communication settings.
• Активирана прекумерна заштита: The BMS protects against overcharge, overdischarge, overcurrent, and high temperature. Identify the cause of the trigger (e.g., excessive load, faulty charger, high ambient temperature) and rectify it. The BMS will typically resume normal operation once the condition is resolved.
