DALY LFP 8S 100A 3.6V BMS Hardware Lithium Battery

The DALY LFP 8S 100A 3.6V BMS is a high-performance Battery Management System (BMS) designed for managing 8-cell Lithium Iron Phosphate (LiFePO4) battery packs, specifically engineered to handle larger loads and higher currents. Below is a detailed description of the hardware features and specifications of this BMS:

Key Features and Specifications:

1. Battery Configuration:
   • 8S Configuration: The BMS is intended for 8-series LiFePO4 battery packs, which means the system is designed to manage 8 individual cells connected in series. This configuration gives the pack a nominal voltage of 28.8V (3.6V per cell).
   • Nominal Voltage: 3.6V per cell, totaling 28.8V nominal.
2. Current Rating:
   • 100A Continuous Current: This BMS can handle 100A continuous discharge current, which is ideal for higher power applications, such as electric vehicles, large-scale energy storage systems, and heavy-duty power equipment.
3. Protection Features: The DALY LFP 8S 100A BMS provides multiple protection mechanisms to ensure the safety and longevity of the battery pack:
   • Overcharge Protection: The BMS disconnects the charging circuit if any cell reaches the overcharge voltage (typically 3.65V per cell), preventing damage to the cells from overcharging.
   • Overdischarge Protection: Disconnects the load if the voltage of any cell drops.
4. Cell Balancing:
   • Active Cell Balancing: The BMS features cell balancing to ensure that all cells in the series-connected pack have equal voltage levels. This prevents overcharging or overdischarging of individual cells, which can lead to imbalance and reduce the overall performance and lifespan of the battery pack.
5. Communication & Monitoring:
   • CAN Bus or UART Communication: Many versions of this BMS are equipped with CAN Bus or UART communication protocols, allowing for integration with external systems or controllers. This enables real-time monitoring and data exchange, such as:
     • State of Charge (SOC): Tracks the remaining charge in the battery.
     • Voltage and Current: Monitors the overall voltage of the pack, as well as individual cell voltages, and the current draw.
6. Hardware Features:
   • Mosfet Transistors: The BMS typically uses high-quality MOSFETs for power management, which ensures smooth current handling, and reduces heat generation and energy loss.
   • High-Quality PCB: The BMS comes with a robust printed circuit board (PCB) that is designed to handle high currents and provide excellent heat dissipation.
7. Applications:
   • Electric Vehicles (EVs): Ideal for use in electric motorcycles, scooters, cars, and other electric transportation systems requiring high current draw and safety features.
   • Energy Storage Systems (ESS): Suitable for large-scale battery storage solutions for solar or off-grid applications where high current output is necessary.

Summary:

The DALY LFP 8S 100A 3.6V BMS is a high-end battery management system designed to manage 8-series LiFePO4 battery packs with a continuous discharge rating of 100A. It offers advanced protection features like overcharge, overdischarge, overcurrent, short-circuit, and temperature protection, along with active cell balancing for improved battery health. The BMS also includes communication features for real-time monitoring via CAN Bus or UART, making it a versatile solution for electric vehicles, energy storage systems, and other high-power applications. With its robust hardware design, this BMS ensures safety, efficiency, and long-term performance for high-current battery packs.
