Abstract
An electric storage system includes electric storage blocks and a controller determining the state of each of the electric storage blocks. The plurality of electric storage blocks are connected in series, and each of the electric storage blocks has a plurality of electric storage elements connected in parallel. Each of the electric storage elements has a current breaker breaking a current path within the electric storage element. The controller acquires at least one parameter of an internal resistance and a full charge capacity of each of the electric storage blocks, and uses a change rate between the acquired parameter and a reference value to specify the number of current breakers in a broken state (the number of breaks) in each of the electric storage blocks. The reference value refers to the value of the parameter in the electric storage block not including the current breaker in the broken state.
