摘要： A power supply system includes a plurality of sweep modules, a defect detecting unit, and a control unit. Each sweep module includes a battery module and a power circuit module. The defect detecting unit detects a defect for each sweep module. The number of sweep modules is greater S (S≥2) than a minimum number of sweep modules required for operation. When the number of defective sweep modules in which a defect has been detected is equal to or less than F (2≤F≤S), the control unit is configured to disconnect the defective sweep modules from a main line and to continuously execute sweep control.

摘要： A backup battery charging system for a building management system is disclosed. Components of the charging system include an analog power converter, a voltage feedback loop and a current feedback loop. The feedback loops each include at least one digital resistor. The system panel, in turn, includes at least one microcontroller that controls the building management system and also controls the charging system. The charging system is “software defined,” in that the microcontroller controls the charging system by updating the digital resistors in the feedback loops to control the analog power converter. In one example, the building management system is a fire alarm system controlled by a fire control panel as the system panel.
