DALY BMS Lifepo4 8S/50A Smeport W/P Lithium Battery

he DALY BMS LiFePO4 8S/50A SamePort W/P is a Battery Management System (BMS) designed for LiFePO4 (Lithium Iron Phosphate) battery packs with an 8S configuration and 50A continuous discharge current rating. This system is ideal for managing high-power applications while ensuring the safety, longevity, and reliability of the battery. Below is a detailed description of its key features:

Key Features:

1. Voltage and Configuration:
   • 8S Configuration: This BMS is designed for an 8-cell series-connected LiFePO4 battery pack, where each cell is connected in series to form the full battery pack.
   • Nominal Voltage: The nominal voltage of an 8S LiFePO4 battery pack is 25.6V (3.2V per cell × 8 cells).
   • Fully Charged Voltage: When fully charged, the pack reaches 33.6V (4.2V per cell × 8 cells).
   • Discharge Voltage Range: The BMS ensures that the battery pack is protected from discharging below 21.6V (3.0V per cell × 8 cells), safeguarding the cells from deep discharge damage.
2. SamePort (W/P) Design:
   • SamePort: The “SamePort” feature means that the BMS utilizes a single connection port for multiple functions, such as charging, discharging, and cell balancing. This simplifies wiring and installation, reducing the number of separate connections required for system integration.
   • W/P (Waterproof/Weatherproof): This BMS is designed with protection against dust and water ingress, ensuring durability and reliable operation in harsh or outdoor environments. This makes it suitable for use in applications exposed to the elements, such as solar energy systems and electric vehicles.
3. Current Handling:
   • 50A Maximum Continuous Discharge Current: The BMS is capable of handling up to 50A of continuous discharge current, making it ideal for high-power applications such as electric vehicles (EVs), solar storage systems, and other high-current devices. The 50A rating allows for handling larger loads and more powerful systems.
   • Peak Current: The BMS can handle short-duration peak currents higher than 50A, typically to accommodate power surges during startup or brief heavy load conditions.
4. Battery Protection Features:
   • Over-voltage Protection: Prevents overcharging of the cells by disconnecting the charging process if the voltage of any cell exceeds safe levels (typically 4.2V per cell), thus protecting the battery pack from damage due to excessive voltage.
   • Under-voltage Protection: The BMS disconnects the load when any cell voltage drops too low (typically below 3.0V per cell), ensuring the pack does not experience deep discharge, which could lead to cell damage.
   • Over-current Protection: If the discharge current exceeds the safe threshold (50A), the BMS will disconnect the load to avoid overheating, battery damage, or fire hazards.
   • Short-circuit Protection: The BMS will immediately cut off power if a short circuit is detected, protecting the battery pack and preventing damage or dangerous situations.
   • Temperature Protection: This feature monitors the temperature of the battery pack and halts charging or discharging if the temperature exceeds safe limits, preventing thermal runaway and ensuring the cells do not overheat.
5. Cell Balancing:
   • The BMS includes active or passive cell balancing to ensure all cells in the pack are charged equally. This prevents certain cells from becoming overcharged while others remain undercharged, which could otherwise lead to a reduction in battery life and performance.
6. Applications:
   • The DALY BMS LiFePO4 8S/50A SamePort W/P is designed for high-power applications, including:
     • Electric Vehicles (EVs): Provides reliable power management for electric cars, bikes, and scooters.
     • Solar Energy Storage: Ideal for managing large battery banks used in solar power systems for off-grid or grid-tied storage.
     • Uninterruptible Power Supplies (UPS): Can be used in systems that require continuous power supply even during outages.
     • Marine and RV Applications: Suitable for marine batteries or recreational vehicle battery systems that need robust power management.
     • High-Power Energy Systems: Works well in any application requiring a stable and safe power source with higher current demands.
7. Communication Features:
   • Depending on the model, the BMS may include communication options such as CAN Bus or UART for integration with monitoring systems. These interfaces allow users to access detailed information about the battery’s performance, including state of charge (SOC), voltage, temperature, and other critical parameters. This communication can be used to monitor the battery remotely or integrate the BMS with a larger energy management system.

Summary:

The DALY BMS LiFePO4 8S/50A SamePort W/P is a powerful and reliable battery management system designed for 8S LiFePO4 lithium battery packs. With its 50A continuous discharge current rating, this BMS is ideal for high-power applications such as electric vehicles, solar energy storage, UPS systems, and high-current devices. It provides essential protection features, including over-voltage, under-voltage, over-current, short-circuit, and temperature protections, ensuring the safety and longevity of the battery pack. The SamePort design simplifies wiring, while the weatherproof construction ensures durability in outdoor or harsh conditions. This BMS is perfect for applications that require reliable, high-performance, and safe battery management.
