How is a battery and status monitored?

A battery's status is monitored using various metrics such as voltage, current, temperature, and state of charge (SoC). These parameters are often tracked by a battery management system (BMS), which employs sensors to collect data and algorithms to assess battery health and performance. The BMS can provide real-time information on the battery's condition, ensuring safe operation and optimizing charging and discharging processes. Additionally, some systems may utilize communication protocols to relay this information to users or devices for further analysis.
