Lithium battery (ternary, iron lithium, sodium battery) BMS protection board supports lead to lithium Bluetooth 485 CAN communication protocol customization

Description :

  The lithium battery protection board is the core component of the battery management system (BMS), mainly used to monitor and manage the charging and discharging process of the lithium battery pack, prevent overcharging, overdischarging, overcurrent, and short circuit, thereby ensuring the safety and lifespan of the battery pack. This product covers specialized protection boards for battery swapping scenarios, lithium battery conversion protection boards for lead-acid batteries, intelligent protection boards with Bluetooth communication function, and standard 48V household energy storage protection boards. Suitable for electric bicycles, electric motorcycles, home energy storage systems, and various customized lithium battery devices, it solves the pain points of traditional battery management, low safety, and invisible status, providing precise cell balance and safety protection for lithium battery applications under different working conditions.

  This series of lithium battery protection boards adopts high-precision voltage acquisition chips and low-power MCU control solutions, supporting voltage monitoring of multiple strings of lithium cells (such as common 12V 24V 36V 48V 60V 72V 96V configurations such as 4-series -12 strings/13 strings/14 strings/15/17/18/19/24/26/32 strings). Equipped with millivolt level voltage detection accuracy to ensure consistent management of battery cells. Built in temperature sensor interface, supporting high temperature protection for charging and discharging. In terms of process, double-sided fiberglass PCB board is used, with low impedance and low heat generation. The high current circuit is thickened or optimized with copper coating to withstand continuous high current impact. Compliant with the general safety standards of the electronics industry, it has strong anti-interference ability and high stability. Some models support real-time uploading of battery SOC, SOH, voltage, current, and temperature data to the mobile app through Bluetooth module.

  When selecting, it is necessary to clarify the application scenario and battery parameters. The battery protection board should focus on the durability and fast balancing ability of high-frequency charging and discharging; The lead to lithium protection board needs to be compatible with the charging logic of the original lead-acid charger or have a specific wake-up function to avoid charging failure or locking of the protection board due to mismatched chargers; Bluetooth protection board is suitable for users or maintenance teams who need to remotely monitor battery status; The standard 48V home storage protection board focuses more on long-term static low power consumption and high reliability. If the original system uses lead-acid batteries, it is necessary to confirm whether the protection board supports the "lead to lithium" mode, otherwise the battery may be damaged due to differences in charging voltage range. For equipment with special sizes or current requirements, customized services can be selected, which require specific parameters such as the number of cell strings, continuous current, peak current, and installation size.

  Before installing the lithium battery protection board, please make sure to confirm the wiring sequence. Usually, connect the busbar (collection line) first and then connect the main charging and discharging negative pole. It is strictly prohibited to reverse or misconnect to avoid burning the protection board. During use, the protective board should be avoided from being exposed to damp, high temperature, or strong vibration environments for a long time. Regularly check whether the wiring terminals are loose and observe whether the protective board has any abnormal heating phenomenon. If the battery cannot be charged or the output is interrupted, you can first check whether the protection board has entered the protection state (such as overvoltage, undervoltage, overcurrent), and attempt to reset by briefly disconnecting the load or charging end. In daily maintenance, keep the battery pack well ventilated and avoid long-term storage of fully charged or empty batteries to extend the overall service life of the protective board and battery pack.
