Before turning on the power, please confirm whether the connection of the acquisition line and other wiring is correct , whether the power provided to the protection board is within the required range, check whether the protection board has been placed safely, and the total voltage of the protection board battery does not exceed 90V . The power supply of the protection board can only be activated after confirmation , otherwise it may cause serious consequences such as abnormal operation or even burning

After confirming that the above operations are correct, you can power on the protection board . Method 1 , activate by shorting the activation connector on the protection board; Method 2, activate the charger , the charger needs to have a voltage output, and the output voltage is greater than the total voltage of the battery by more than 3 V.

A Smart BMS, also known as an Intelligent BMS or Smart Battery Management System, is an advanced battery management system that incorporates additional features and capabilities beyond traditional BMS functions. A Smart BMS leverages advanced electronics, sensors, communication interfaces, and software algorithms to provide enhanced monitoring, control, and communication capabilities for battery systems.

Here are some key features and functions commonly found in a Smart BMS:

1. Advanced Monitoring: A Smart BMS provides comprehensive monitoring of battery parameters such as cell voltage, current, temperature, state of charge (SOC), state of health (SOH), and other relevant data. It allows real-time monitoring and accurate measurement of battery performance and condition.
2. Communication Interfaces: Smart BMS systems often include communication interfaces such as CAN bus (Controller Area Network), RS485, Ethernet, or wireless protocols like Bluetooth or Wi-Fi. These interfaces enable seamless integration with external devices, such as controllers, inverters, or monitoring systems, allowing for remote monitoring, control, and data exchange.
3. Data Logging and Analysis: Smart BMS systems typically include data logging capabilities, storing historical battery performance data, alarms, and events. This data can be analyzed to assess battery health, identify trends, and optimize battery usage and performance. Some Smart BMS systems may also offer cloud connectivity for remote data storage and analysis.
4. State Estimation and Predictive Algorithms: Smart BMS systems employ advanced algorithms and models to estimate the state of charge (SOC), state of health (SOH), and remaining battery capacity accurately. These algorithms can provide more accurate predictions of battery behavior, enabling better decision-making for optimal battery usage and maintenance.
5. Fault Detection and Diagnostic Tools: Smart BMS systems incorporate diagnostic tools and fault detection mechanisms to identify abnormal battery conditions or malfunctions. They can trigger alarms, notifications, or take specific actions to mitigate potential risks or damage.
6. Cell Balancing and Equalization: Smart BMS systems often include active or passive balancing mechanisms to equalize the state of charge or voltage levels among individual cells or modules within a battery pack. This ensures optimal cell utilization and extends the overall battery pack's lifespan.
7. Safety Protections: Smart BMS systems prioritize safety and incorporate various protection mechanisms, such as overcharge protection, over-discharge protection, overcurrent protection, temperature monitoring, and short-circuit protection. These features safeguard the battery system and prevent potential hazards or damage.
8. User Interface and Control: Some Smart BMS systems offer user-friendly interfaces, such as LCD displays or mobile applications, allowing users to monitor battery status, configure settings, and receive alerts or notifications.

Smart BMS systems are commonly used in various applications, including electric vehicles (EVs), renewable energy systems, industrial equipment, and grid energy storage. They enable advanced battery management, improved performance, and enhanced safety, while also facilitating integration with other components and systems within a larger energy ecosystem.

BMS Active and passive balance are two methods used in battery management systems (BMS) to equalize the state of charge (SOC) or voltage levels of individual cells within a battery pack. The goal is to ensure that each cell operates within a desired range and maximize the overall performance and lifespan of the battery pack.
