Battery Management System DALY, 50A 8-24S, 24-72V BMS with 1A Active Balancer and Built-in Bluetooth for Lithium/LFP/LTO Battery Pack

Description:

The DALY 50A 8S 24V Smart BMS is a Battery Management System designed for managing 24V lithium-ion battery packs, typically used in electric vehicles (EVs), solar storage, or other battery-powered applications. It helps maintain the health and safety of the battery pack by balancing the cells, protecting the pack from overcharging, over discharging, and overcurrent conditions.

Key Specifications:

1. Rated Current: 50A

   • This indicates the maximum continuous discharge current the BMS can handle.

2. Cell Configuration: 8S (8 Series cells)

   • The “8S” means the BMS is designed to manage an 8-cell lithium-ion pack connected in series. This typically results in a nominal voltage of 24V (3.7V * 8 cells), with a full charge voltage around 29.6V (4.2V * 8 cells).

3. Voltage Range:

   • Nominal Voltage: 24V
   • Voltage Range: 21V to 29.6V (8S Li-ion range)

4. Active Balancer: 1A Active Balancer

   • The active balancer ensures that all cells in the pack are kept balanced by redistributing energy from higher charged cells to those with lower charge. This ensures better performance, prevents cell overvoltage, and increases the overall lifespan of the battery pack.

5. Bluetooth Integration:

   • Built-in Bluetooth allows for wireless communication with a mobile device for monitoring and configuration. Using an app, users can monitor the battery’s voltage, current, temperature, and other critical parameters in real-time.

6. Overcharge and Over discharge Protection:

   • The BMS protects the battery pack from overcharging (when the voltage of any individual cell exceeds a safe level) and over discharge (when the voltage drops too low), which can cause damage to lithium-ion cells.

7. Overcurrent and Short-Circuit Protection:

   • The BMS includes overcurrent protection (to prevent excessive discharge or charge currents) and short-circuit protection to safeguard the battery pack against sudden failures.

8. Temperature Protection:

   • It protects the battery pack by monitoring the temperature. If the pack reaches unsafe temperatures, the BMS will disable charging or discharging to prevent overheating or thermal runaway.

9. Self-Protection:

   • The BMS has a self-protection mechanism that can disable its operation in extreme cases like overvoltage, undervoltage, overcurrent, and excessive temperature.

Features:

1. Cell Voltage Monitoring:

   • It can monitor the voltage of each individual cell in the battery pack, helping to detect imbalance or undercharged cells.

2. Charge/Discharge Mosfet Control:

   • The BMS controls the MOSFETs that allow or stop current flow to/from the battery pack during charging and discharging.

3. Data Logging:

   • It stores data about the battery’s performance, and this data can be accessed via Bluetooth.

4. Easy Integration:

   • DALY BMS modules are generally designed to be easy to integrate with existing battery packs and chargers, providing an efficient and reliable solution for battery management.

5. LED Indicators:

   • Many versions of the DALY BMS come with LED lights indicating the status of the battery (e.g., charging, discharging, fault conditions, etc.).

6. Communication Protocol:

   • It usually supports a communication protocol such as CAN Bus or RS485, allowing it to be integrated with more complex systems for monitoring and control.

Applications:

• Electric Vehicles (EVs): Battery packs in electric cars, e-bikes, and other vehicles.
• Energy Storage Systems: Solar energy storage or off-grid battery systems.
• Robotics: Used in robotics applications requiring reliable battery management.
• DIY Projects: For hobbyists and engineers working on battery-powered devices.

Example of Use:

If you’re using this BMS for a lithium-ion battery pack in an electric bike, it will:

• Prevent the battery from overcharging or undercharging.
• Protect the battery against excessive current draw (e.g., in an emergency or during high acceleration).
• Help keep all cells balanced, which is key for long battery life.
• Allow you to monitor the battery’s health through a mobile app via Bluetooth.
