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. Or if there are different brands and models of BMS that need to be added to the app, please feel free to contact the author to update the iteration 64977884@qq.com Fusion BMS 是一款可读取不同品牌电池的智能管理系统,实现监控电池状态,实时收集储存、处理电池运行过程中的信息,与外部设备进行信息交换,解决锂电池系统的安全性、易用性和使用寿命的关键问题,实现延长电池使用寿命,增强电池成组后的稳定性。 1. 显示实时电压、电流、功率、内阻等参数数值,以仪表盘和数字形式展示; 2. 显示所有单体电池的实时电压、告警状态若上报参数触发告警值或保护值,则提示告警; 3.电芯的每一项数据对比,电压差。最大电压电芯 最小电压电芯。以及电芯均衡的显示 4.电芯温度预警。 温度过高,短路,过压,欠压实时告警 5.记录每个时刻发生的警告。 6.兼容各种品牌的电池。 在使用过程中,如果无法连上电池。或有不同品牌型号的BMS需要加入到app内,请随时联系作者更新迭代 64977884@qq.com
