Безбедносни мерки на претпазливост
- Always disconnect the charger and load before performing any maintenance or wiring changes.
- Ensure correct polarity when connecting the BMS to the battery pack and external devices. Incorrect wiring can cause damage to the BMS and battery.
- Wear appropriate personal protective equipment (PPE), including insulated gloves and eye protection, when working with high-voltage батериски системи.
- Avoid short-circuiting battery terminals or BMS connections.
- Install the BMS in a well-ventilated area, away from flammable materials.
- If the BMS shows signs of damage or malfunction, discontinue use immediately and consult a qualified technician.
Поставување
1. Wiring the BMS
Careful wiring is crucial for the proper function and safety of your battery system. Follow these steps precisely:
- Подгответе го батерискиот пакет: Ensure all individual cells in your 20S Li-ion battery pack are balanced and at a safe voltagниво пред да го поврзете BMS.
- Поврзете ги жиците за балансирање: Connect the balance wires from your battery pack to the BMS balance port. Ensure the wires are connected in the correct sequence, starting from the lowest cell voltage (B-) to the highest (B+). Важно: Do not connect the main B- wire to the BMS yet.
- Verify Balance Wire Voltages: Before connecting the BMS, use a multimeter to measure the voltage between adjacent balance cables. The reading should approximate the nominal voltage of a single cell. This confirms correct wiring.
- Connect Main Wires: Connect the main negative battery terminal (B-) to the corresponding B- terminal on the BMS. Connect the main positive battery terminal (B+) to the P+ terminal on the BMS.
- Поврзување на товар/полнач: Connect your load and charger to the P- terminal on the BMS. The DALY Smart BMS uses a common port for both charging and discharging.

2. Bluetooth Module Connection and App Setup
The DALY Smart BMS includes a Bluetooth module for wireless communication with your smartphone. This allows for real-time monitoring and parameter adjustments.
- Connect Bluetooth Module: Plug the Bluetooth module into the designated port on the BMS.
- Активирајте го BMS: Press the button on the Bluetooth module or the BMS to activate the smart BMS.
- Преземи апликација: Download the "Smart BMS" application from your device's app store (available for iOS and Android).
- Поврзете се преку Bluetooth: Open the Smart BMS app on your phone. The app will scan for available Bluetooth devices. Select the corresponding Bluetooth ID of your BMS to connect.

3. Initial Parameter Settings
Upon first power-on and connection, it is essential to configure the BMS parameters via the app or PC software. The initial password for parameter changes is 123456.
- Set Rated Capacity: Adjust the "rated capacity" (e.g., 10.0AH) to match the actual capacity of your battery pack. Incorrect capacity settings will lead to inaccurate State of Charge (SOC) readings.
- Verify Cell Type: Ensure the "type of battery" is correctly set to Li-ion.
- Review Поставки за заштита: Check and adjust protection parameters such as cell over-voltagд, под-волtage, total pack over-voltagд, под-волtage, and over-current limits according to your battery specifications.

2. Programmable Protection Functions
The BMS is equipped with various programmable protection features to safeguard your battery:
- Заштита од прекумерно полнење: Stops charging when the battery voltage reaches a set limit.
- Заштита од прекумерно празнење: Stops discharging when the battery voltage drops to a set limit.
- Заштита од прекумерна струја: Stops charging or discharging if the current exceeds the programmed limit.
- Заштита од температурата: Disables current flow if the battery temperature exceeds or falls below safe operating limits.
- Voltagе Балансирање: The BMS features an automatic balancing function to equalize cell voltages, which is crucial for battery longevity.

Одржување
Regular maintenance helps ensure the longevity and optimal performance of your DALY Smart BMS and battery pack.
- Редовно следење: Periodically check the battery parameters via the Smart BMS app to ensure all cells are balanced and operating within safe limits.
- Интегритет на поврзувањето: Inspect all wiring connections, especially the balance wires and main power cables, for any signs of corrosion, looseness, or damage. Ensure they are securely fastened.
- Заштита на животната средина: The BMS is designed to be waterproof, moistureproof, fireproof, and dustproof. However, avoid exposing it to extreme conditions or direct water immersion. Keep the cooling fan free from obstructions to ensure proper heat dissipation.
