Battery backup system and battery backup module thereof

A battery backup system, comprising:

• a base having a plurality of receiving portions;
• a plurality of battery backup modules, each of said battery backup modules comprises:
• a first modular casing, wherein said first modular casing is swappable to be accommodated within one of said receiving portions of said base;
• a microcontroller disposed in said first modular casing;
• an energy storage unit disposed in said first modular casing and connected with said microcontroller for charging or discharging electrical energy;
• and
• a DC-DC converting circuit disposed in said first modular casing and connected with said microcontroller for converting a DC voltage;
• and
• a control module comprising a second modular casing, wherein said second modular casing is swappable to be accommodated within one of said receiving portions of said base,
• wherein said energy storage unit is controlled to charge or discharge electrical energy by said microcontroller when said first modular casing is accommodated within said receiving portion, and a DC voltage inputted to or outputted from said energy storage unit is converted by said DC-DC converting circuit controlled by said microcontroller.
