Careful wiring is critical for the correct and safe operation of the BMS. Follow these steps precisely:
5.1 Sujungimo schema
Image: Wiring diagram for the DALY Smart BMS.
5.2 Step-by-Step Wiring
- Paruoškite įrankius: Ensure you have necessary tools such as a soldering machine (if needed, suggest using 662°F/350°C), scissors, double-sided tape, tin wire, and a multimeter.
- Connect Balance Wires: First, connect the balance wires to your battery pack. Ensure the balance wires are welded correctly.
- Connect BMS to Battery: Connect the main negative terminal (B-) of the battery pack to the B- terminal on the BMS. Connect the main positive terminal (B+) of the battery pack to the P+ terminal (if applicable, or ensure the charger/load positive connects directly to battery B+).
- Connect Balance Wire Harness: Plug the balance wire harness into the BMS connection port. Ensure the red balance wire is connected to the highest positive cell.
- Connect Load/Charger: Connect the negative terminal of your motor/load and charger to the P- terminal on the BMS. The positive terminals of the motor/load and charger connect directly to the battery pack's positive terminal (B+).
- Install Cooling Fan: Keep the red cooling surface of the BMS uncovered to allow for proper fan operation.
- Patikrinkite laidus: Before proceeding, use a multimeter to measure the voltage between adjacent balance cables. This voltage should approximate the nominal voltage of a single cell string, confirming correct wiring.
- Activate BMS: Plug in the NTC (temperature sensor) and Bluetooth module. Press the activation button on the BMS to power it on.
Svarbi pastaba: Disconnect balance wires and the BMS connection port before welding black and red balance wires on the battery pack.
