All of the information about the individual batteries and the respective individual statuses collected from the BACS battery modules is compiled here. The BACS web manager evaluates all of the data in real time and sends necessary control commands to the BACS battery modules, based on the data, to keep the batteries in the optimum charging state.
If deviations arise, the web manager can, if needed, issue recommendations and, in the event of an emergency, even take active emergency measures to, for instance, prevent a battery from thermally overloading.
Precisely because of the option to actively manage batteries, BACS is compatible with all types of batteries currently available on the market. Ultimately, the type of battery you want to use determines the impact of the active management:
For instance, if a lithium-based battery technology is used in the UPS solution, an active charging control is required for technical reasons. A lead-based battery technology, however, is more robust. From a technical perspective, it can also be monitored by a pure monitoring system without charging control, but will wear out relatively quickly. The service life is approximately 1/3 of the design life specified by the manufacturer. Using BACS improves the service life and the general performance by up to 50%. Some batteries can even be used for the entire design life specified by the manufacturer and then, only the battery has to be replaced and not, as usual, all the batteries within a battery string.
