The DALY Smart BMS is a comprehensive Battery Management System designed to monitor and protect lithium-based battery packs (LiFePOâ‚?and others). It features intelligent protection, real-time data communication, and multiple interface ports to ensure battery health, safety, and remote diagnostics. The system integrates UART, CAN, and RS-485 communication along with Bluetooth support for enhanced connectivity. Passive balancing is included to maintain cell voltage uniformity and extend battery life.
Key Features:
- Supports various lithium battery chemistries including LiFePOâ‚?(configurable series)
- Multiple communication interfaces: UART, Bluetooth, CAN, and RS-485
- Integrated protection against over-voltage, under-voltage, overcurrent, short-circuit, and over-temperature
- Passive balancing to improve performance and prolong battery pack lifespan
- Real-time data monitoring and parameter configuration via app or external controller
- Digital I/O and switch control for custom integration and alerts
- Ideal for solar energy systems, EVs, powerwalls, and industrial battery management
