Abstract: The invention relates to a power management system for supplying backup DC power to peak and/or high current demand battery applications, such as motor starting or an uninterruptible power supply (UPS) used to power a critical load, such as, a data bus or other critical load, after an event, such as loss of primary AC or DC input, during relatively cold ambient temperatures. Two or more heaters can be provided; for example, a low power heater and a high-power heater. In a maintenance mode, the low power heater is used to maintain batteries at a predetermined temperature. In this mode, a battery charger is used to power the low power heater. In a boost mode, after the primary AC or DC input is restored, and battery temperature is too low to back up the critical load, the battery charger supplies power to one or both of the heaters.

Abstract: A double-sided printed circuit board and method for manufacturing requires a ceramic substrate, two circuit layers, and conductive paste. The ceramic substrate includes two opposite surfaces, and at least one through hole passing through the two opposite surfaces. The two circuit layers can be plated on the two opposite surfaces. The conductive paste is infilled into the full extent of the through hole and thermo-cured, the ingress of electroplating materials into the hole is thus prevented. The method has low process requirement and high reliability in use.

The heat generated by the electronic element is conducted through the filler directly to the substrate for heat dissipation.

Abstract: A power management system is disclosed for providing an indication of the required available capacity (RAC) available from a backup battery unit (BBU) for backup or peak loading as required by a critical DC load, such as a computer bus. The power management system is configured to repeatedly determine the gross remaining capacity of the backup battery unit (BBU). The system processes this information and other measured or known battery parameters to determine the required available capacity (RAC). The RAC is based upon the required capacity of the critical load to which the BBU is connected. In general, the RAC is the difference between the gross remaining capacity of the battery at a given point in time and the required capacity of the critical load. In accordance with an important feature of the power management system, an indication of the RAC is provided.
