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.

BMS Lifepo4 stands for Battery Management System, and LiFePO4 refers to Lithium Iron Phosphate, which is a type of rechargeable lithium-ion battery chemistry. Therefore, BMS LiFePO4 refers to a Battery Management System specifically designed for LiFePO4 batteries.

A BMS for LiFePO4 batteries is responsible for monitoring and controlling various aspects of the battery's operation to ensure safe and efficient performance. Here are some key functions and features typically found in a BMS for LiFePO4 batteries:

1. Cell Balancing: LiFePO4 batteries are composed of multiple individual cells connected in series or parallel configurations. The BMS monitors the voltage and state of charge of each cell and performs cell balancing to equalize the charge levels among all cells. This helps optimize the overall battery capacity and prolong its lifespan.
2. Overcharge and Overdischarge Protection: The BMS safeguards the LiFePO4 battery by preventing overcharging or overdischarging, which can lead to battery damage or safety hazards. It monitors the battery voltage levels and disconnects the load or charging source when the battery reaches critical voltage thresholds.
3. Temperature Monitoring: LiFePO4 batteries are sensitive to temperature extremes. The BMS continuously monitors the battery temperature and takes appropriate action, such as reducing the charging or discharging rate or triggering protective measures if the temperature exceeds safe limits.
4. Voltage and Current Monitoring: The BMS Lifepo4 tracks the battery's voltage and current levels during charging and discharging. It ensures that the voltage and current stay within safe limits and can provide accurate readings for monitoring the battery's state of charge and overall performance.
5. Communication and Data Logging: Some advanced BMS systems for LiFePO4 batteries offer communication interfaces such as CAN bus, RS485, or Bluetooth. These interfaces allow for real-time monitoring and control of the battery system, as well as data logging for performance analysis and diagnostics.
6. Fault Detection and Alarms: The BMS Lifepo4 is equipped with fault detection mechanisms to identify abnormalities or malfunctions in the battery system. It can trigger alarms, notifications, or shut down the system to prevent further damage or risks.
7. State of Charge (SOC) Estimation: The BMS employs algorithms and calculations to estimate the battery's state of charge, providing an indication of how much usable energy remains in the battery

It's advisable to consult the battery and BMS manufacturer's specifications and guidelines to ensure compatibility and proper integration with your LiFePO4 battery system.

BMS Lifepo4 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.
