Refer to Figure 1-20. The Battery Charger Power Supply (BCPS) monitors various system power levels
and switches the sourced power between the commercial power and batteries to assure continued service.
There are three basic blocks used to illustrate the functions within the BCPS; the Analog Multiplexer, PIC
processor with A/D converter and the DC to DC converter.
