DALY LFP 24S 40A 3.6V BMS Hardware Lithium Battery

The DALY LFP 24S 40A 3.6V BMS is a Battery Management System (BMS) designed for lithium iron phosphate (LiFePO4 or LFP) battery packs. Here’s a detailed description of its features and specifications:

Key Features:

1. Battery Type Compatibility:

   • Specifically designed for LiFePO4 (LFP) batteries, which are known for their safety, long cycle life, and stable performance.

2. Voltage:

   • The system is designed for 24 series (24S) configurations, meaning it can handle a pack consisting of 24 individual cells. The typical voltage for a single LiFePO4 cell is 3.2V, and when configured in series, the pack voltage will be around 76.8V (3.2V x 24).

3. Current Handling:

   • 40A continuous discharge current, meaning it can handle up to 40 amps of continuous current without overheating or failing. This is suitable for mid-range to high-power applications like electric vehicles, solar storage, or power tools.

4. Voltage Monitoring:

   • Provides voltage monitoring for each individual cell, ensuring they stay within safe operating limits.
   • Includes over-voltage and under-voltage protection to prevent cells from being overcharged or over-discharged, which could cause damage or failure.

5. Current Protection:

   • It also includes overcurrent protection, ensuring that the system won’t be overloaded with excessive current.
   • Short-circuit protection is also included to safeguard against dangerous situations.

6. Temperature Monitoring:

   • Many BMS systems like this one will have temperature sensors to monitor the pack’s temperature. This helps prevent issues like overheating during charging or discharging.

7. Balancing:

   • The BMS includes cell balancing, ensuring that all cells in the series are charged to the same voltage level, which is crucial for maximizing battery performance and longevity.

8. Communication Features:

   • Often includes communication ports such as CAN bus or RS485 for integration with external systems or monitoring devices.

9. Protection Features:

   • Overcharge protection (to prevent excessive voltage during charging).
   • Over-discharge protection (to avoid deep discharging of the battery pack, which can damage the cells).
   • Overcurrent and short-circuit protection to safeguard the battery from potentially dangerous conditions.

10. Applications:

• This BMS is suitable for use in various electric vehicles (EVs), solar energy storage systems, uninterruptible power supplies (UPS), and electric bikes, as well as other applications requiring a reliable, high-capacity LiFePO4 battery pack.

Summary:

The DALY LFP 24S 40A 3.6V BMS is a robust, feature-packed Battery Management System designed for 24-cell lithium iron phosphate battery packs. It provides essential protections, such as overcharge, over-discharge, overcurrent, and short-circuit protection, along with cell balancing and temperature monitoring. The 40A current rating makes it suitable for moderate to high-power applications, ensuring the longevity and safety of the battery pack.
