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.
