DALY NMC 7S 80A Waterproof Battery Management System-BMS Protection Board

The DALY NMC 7S 80A Waterproof Battery Management System (BMS) Protection Board is a high-performance BMS designed to protect and manage 7-series lithium-ion battery packs using NMC (Nickel Manganese Cobalt) chemistry. With its robust features, this BMS ensures optimal battery performance, longevity, and safety, particularly for high-power applications that demand higher current. Below is a detailed description of its key features and functionalities:

Key Features:

1. 7S Configuration:
   • The 7S configuration means that the BMS is designed for 7 cells connected in series, providing a total voltage range of 21V to 29.4V (3.0V to 4.2V per cell).
   • This configuration is widely used in electric vehicles (EVs), electric bikes (eBikes), and energy storage systems.
2. 80A Continuous Discharge Current:
   • This BMS can handle a continuous discharge current of 80A, which makes it suitable for high-performance applications requiring significant power, such as electric vehicles, high-power eBikes, solar energy storage systems, and more.
   • The 80A capacity allows it to manage heavy load currents without overloading the battery or causing overheating, ensuring safe operation under high-power conditions.
3. Waterproof Design (IP65 Rating):
   • The BMS is built with a waterproof design that meets IP65 standards, ensuring it is resistant to dust and water splashes. This feature is crucial for outdoor applications, ensuring the BMS operates reliably even in harsh or wet environments.
   • The waterproof capability makes it ideal for use in electric scooters, electric bikes, and off-grid solar power systems where exposure to moisture is common.
4. Advanced Protection Features:
   • Overcharge Protection: Prevents the battery from being charged beyond its safe voltage (typically 4.2V per cell), protecting it from overcharging, overheating, and potential fire hazards.
   • Over-discharge Protection: Disconnects the battery if the voltage drops below a safe level (typically 3.0V per cell), avoiding deep discharge that can damage the battery and reduce its lifespan.
5. Cell Balancing:
   • The passive cell balancing feature ensures that all cells in the battery pack are charged evenly, which helps maintain the overall health of the battery.
   • Balancing prevents some cells from being overcharged while others are undercharged, optimizing battery efficiency and extending its life.
6. Communication and Monitoring:
   • Many DALY BMS systems, including this model, are equipped with communication ports such as UART or CAN bus, allowing for remote monitoring of the battery’s health, voltage, current, and temperature.
   • This feature enables you to keep track of real-time performance and diagnostic information, providing useful data for maintenance and performance optimization.
7. Applications:
   • Electric Vehicles (EVs): With its 80A current handling capability, this BMS is well-suited for high-power electric vehicles, including electric cars, electric motorcycles, and electric scooters.
   • Energy Storage Systems: Ideal for solar energy storage systems or off-grid power systems, where high currents are required for charging and discharging large battery banks.
   • Electric Bicycles (eBikes): Perfect for high-performance eBikes that require substantial power for their motors, particularly in off-road or long-range applications.
   • Portable Power Stations: Suitable for high-power portable power systems that demand efficient and reliable battery management.
8. Longer Battery Life:
   • By providing passive balancing, this BMS helps ensure that each cell in the battery pack remains balanced throughout the charging and discharging cycles. This prolongs the battery’s lifespan and prevents issues like voltage imbalances and premature cell degradation.

Summary:

The DALY NMC 7S 80A Waterproof Battery Management System (BMS) Protection Board is a robust and reliable BMS solution for 7S lithium-ion battery packs, offering high discharge current capacity, waterproof protection, and advanced safety features. With its ability to handle 80A continuous discharge current, it is suitable for high-power applications such as electric vehicles, eBikes, solar storage systems, and off-grid power solutions.

The waterproof design (IP65) makes it ideal for outdoor applications, while the overcharge, over-discharge, overcurrent, short-circuit, and over-temperature protections ensure safe operation. Additionally, the cell balancing feature maximizes battery life and performance. This BMS is perfect for applications that demand both high power and safety, ensuring the longevity and efficiency of the battery pack.
