Fusion BMS is an intelligent management system that can read batteries of different brands, monitor battery status, collect, store and process information during battery operation in real time, exchange information with external devices, and solve the problem of safety and ease of use of lithium battery systems. The key issues of performance and service life can be extended to prolong the service life of the battery and enhance the stability of the battery after grouping. 1. Display real-time voltage, current, power, internal resistance and other parameter values in the form of dashboard and digital display; 2. Display the real-time voltage and alarm status of all single cells. If the reported parameter triggers the alarm value or protection value, it will prompt an alarm; 3. Comparison of each data of the cell, the voltage difference. Maximum voltage cell Minimum voltage cell. and cell balance display 4. Cell temperature warning. Over-temperature, short-circuit, over-voltage, under-voltage real-time alarm 5. Log the warnings that occur at each moment. 6. Compatible with various brands of batteries. During use, if the battery cannot be connected.

  • Power, charge, and discharge capacity monitoring
  • Customizable protection functions (overvoltage, overcurrent, etc.)
  • Color LCD display of comprehensive data
  • Voltage and current curve display and export
  • Mobile app control and communication
Features
Read full description

The Pro BMS series voltage and ammeter is a new coulomb meter that can measure various physical parameters such as voltage, current, power, charge and discharge capacity, watt-hour, time, etc. At the same time, parameters can also be set to realize various protection functions such as overvoltage protection, undervoltage protection, overcurrent protection, overpower protection, overtemperature protection and time-limited protection. The meter can automatically identify the direction of current flow In addition, the battery capacity can be monitored in real time and the measured data is displayed on a color LCD, which displays comprehensive and user-friendly information. The Pro BMS series voltage and ammeter adds the function of displaying and exporting voltage and current curves based on the original functions. At the same time, it can be controlled by mobile APP and communication.
