The BACS WEBMANAGER is the central control unit for the system, where all information will be interpreted and stored. The central unit provides control and information for not only the Battery Management system but also for the UPS status and any Environmental products connected within the system. For the battery management system the BACS Web-manager calculates constantly the reference value of the charging voltage, which every accumulator should have the correct overall voltage. If any accumulator deviates from the average charging voltage the BACS WEBMANAGER sends a correction command to the specific BACS module to manage this accumulator. This individual charging/discharging of accumulators is our patented “Equalizing” process.
