Abstract:
    A structure of detecting an anomaly of the battery pack (2) including a plurality of battery cells (41a, 41b, 42a, 42b, 43a, 43b) connected in series or in parallel, which detects whether or not an impedance of at least one of battery cells deviates from a stipulated range. Also, a structure to detect whether or not an impedance change of at least one of battery cells exceeds a stipulated range.
