POWER STORAGE SYSTEM AND OUTPUT CONTROLLER

Title:

POWER STORAGE SYSTEM AND OUTPUT CONTROLLER

Document Type and Number:

WIPO Patent Application WO/2012/053528

Kind Code:

A1

Abstract:

Provided are a power storage system and an output controller that detect the connection mode of a plurality of power storage units arbitrarily connected and control the plurality of power storage units based on the detected connection mode. Six power storage modules (MOD1-MOD6) are serially connected. A total voltage (V(Total)) and individual output voltages (V(1)-V(6)) for each power storage module are supplied to the output controller (ICNT). A control unit (PR) in the output controller (ICNT) determines the connection mode based on whether or not a determination formula is satisfied or not. The determination formula V(1)=V(2)=….=V(N)=(1/M)xV(Total) is used, wherein the number of power storage modules is N, the total output voltage is V(Total), the individual output voltages are V(1), V(2), …, V(N), and the number of parallel connection modes is M. (N/M) parallel M series is determined when the determination formula is satisfied.
