1. What does battery monitoring measure? (1) Intelligent inspection measures the voltage of each individual battery, the charging and discharging current of the battery pack, the voltage of the battery pack, and the environmental temperature. (2) The UPS/EPS battery monitoring and management system detects all battery parameters every 10 seconds. 2. What is the response of battery monitoring? (1) During the impedance testing process of a single battery, there is no need for any human intervention or adjustment to the power status, and it can be fully automated by the system; (2) Capable of conducting impedance tests on individual cells in the battery pack under different states such as float charging, equalizing charging, discharging, and offline; (2) By using the AC impedance testing method, the system should be able to accurately test the impedance of each individual battery, rather than the DC internal resistance. (3) During the impedance testing process of a single battery, the battery pack or some of the connected batteries are not discharged. 3. Alarm and alarm status output of the battery monitoring system (1) The battery monitoring system judges different types of alarms based on real-time monitoring data, and can remotely transmit the alarm status through communication interfaces and switch output nodes; (2) The communication protocol of the battery monitoring system should include the judgment and setting of alarm status, which can send system alarms to the monitoring center in the first time. (3) The battery monitoring system has a separate switch output and indicates different system alarm states through different switch outputs. When there is a communication connection problem, the alarm state can still be judged and output through switch nodes. The system alarm has good real-time performance, and the time from the occurrence of an emergency alarm in the system to the system's switching output of the alarm state should not exceed 20 seconds
