5S-30A TDT Li-ion Battery Management System (BMS)

Overview:

The 5S-30A TDT Li-ion Battery Management System (BMS) is a highly efficient and reliable solution for managing 5-series lithium-ion battery packs. It provides comprehensive protection, monitoring, and balancing to ensure your battery system operates safely and efficiently, making it ideal for electric vehicles, renewable energy storage, robotics, and other high-power applications.

Key Features:

• 5S Configuration: Designed for lithium-ion battery packs with 5 cells in series, offering a nominal voltage of 18.5V and a fully charged voltage of 21V.

• 30A Maximum Current: Supports up to 30 amps of continuous discharge current, making it suitable for high-power applications while ensuring optimal performance and longevity of the battery pack.

• Cell Balancing: Integrated active cell balancing ensures all cells in the battery pack are charged evenly, preventing overcharging or undercharging of individual cells.

• Overcharge/Overdischarge Protection: Safeguards against voltage extremes by cutting off the charging or discharging when preset voltage limits are reached.

• Overcurrent & Short Circuit Protection: Provides real-time protection against excessive current draw, which could otherwise lead to overheating or damage to the cells.

• Temperature Monitoring: Built-in temperature sensors monitor the temperature of the cells during charging and discharging to prevent overheating, ensuring your battery pack stays within safe operating limits.

• Low Standby Power Consumption: Designed with low standby power consumption, minimizing energy loss when the system is idle.

• BMS Communication Interface: Features an analog and digital communication interface for easy integration with external monitoring systems, controllers, or displays.
