Abstract: Since safety certification only applies for lithium-ion battery system up to 48V in Chinese Coal Mine Industry for underground application, standard battery energy storage system (BESS) cannot be directly used to provide emergency power for critical motor load such as fan / pump etc, which are normally rated at a few hundreds volts. This paper develops a modular design defined as Battery Electronic Building Block (BEBB) that integrates 48V battery-inverter pack as one “plug & play” module based on load requirement. It provides a novel integrated battery & power electronics control architecture that does not need a dedicated Battery Management System (BMS) to realize a more robust and reliable battery energy storage system. Based on this concept, a novel de-centralized energy system architecture defined as energy computer is further introduced based on an analogy with personal computer system.

Key words: battery electronic building block (BEBB), energy storage, emergency power application
