BATTERY SYSTEM AND MANAGEMENT METHOD

摘要

A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compute the average current from the measured currents. The state of the battery system is determined as being fully charged, discharging or charging, and the individual battery string currents are compared with the average measured current to determine if the currents are within a threshold value. An alarm indication is provided when one or more o f the currents exceeds a threshold difference. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.
