(1) The energy storage lithium battery BMS has an analog measurement function: it can measure the voltage and temperature of the single cell, and measure the voltage and current of the battery pack. Ensure the safe, reliable and stable operation of the battery, ensure the service life of the single battery, and meet the control requirements for the optimization of the operation of the single battery and the battery pack.

(2) The energy storage lithium battery BMS has online SOC diagnosis: on the basis of real-time data acquisition, an expert mathematical analysis and diagnosis model is established to measure the remaining battery SOC online. At the same time, the SOC prediction is intelligently provided based on the discharge current of the battery and the ambient temperature, and the remaining capacity and reliable use time of the battery under the load are given.

(3) Battery system alarm function: when the battery system is running overvoltage, undervoltage, overcurrent, high temperature, low temperature, abnormal communication, abnormal BMS, etc. It can display and report alarm information.

(4) Battery system protection function: For abnormal faults such as serious overvoltage and overcurrent (short circuit) during operation, the high-voltage control unit is used.

(5) Energy storage lithium battery BMS has communication function: the system can communicate with PCS through can, the communication protocol supports Ankori PCS communication protocol, and communicates with the background through RS485. The communication protocol is the standard MODBUS protocol.

(6) Thermal management function: strictly monitor the working temperature of the battery pack. If the temperature is higher or lower than the protection value, the battery management system will automatically cut off the battery circuit to ensure the safety of the system.

(7) The energy storage lithium battery BMS has the functions of self-diagnosis and fault tolerance.

(8) Operation parameter setting function.

(9) Local running status display function.

(10) The energy storage lithium battery BMS has the function of event and log data recording.

    The above is the embodiment of the spin power intelligent lithium battery, which can represent the embodiment of other intelligent lithium batteries. Spin force electronic power supply has the ability of intelligent lithium battery manufacturing patent development, independent research and development and production of lithium batteries, independent research and development of intelligent lithium battery management system. When choosing an intelligent lithium battery, it can be used as a reference. The intelligence of lithium batteries is an inevitable choice for the development of science and technology.
