    摘要： A battery pack controlling apparatus for controlling input to or output from a battery pack is provided. The battery pack includes a plurality of blocks in series connection. Each of the plurality of blocks includes a plurality of batteries in series connection. The battery pack controlling apparatus includes: a battery power input/output section for controlling input and output of battery power to and from the battery pack; a block voltage detection section for detecting a block voltage of each of the plurality of blocks; a battery current detection section for detecting a battery current of the battery pack; an unusual heating detection section for detecting unusual heating of at least one of the plurality of batteries based on the block voltage and the battery current; and a vehicle controlling section for controlling the battery power input/output section based on results of unusual heating detection by the unusual heating detection section. The unusual heating detection section includes an internal resistance calculation section for calculating an internal resistance of each of the plurality of blocks based on the block voltage and the battery current. The unusual heating detection section detects unusual heating of the at least one of the plurality of batteries based on the internal resistance of each of the plurality of blocks and a predetermined threshold value.

    摘要： By finding a voltage difference ΔV between the maximum value and the minimum value of voltage of each cell constituting a battery set and then combining the voltage difference ΔV with current I passing through the battery set into a value pair and store a plurality of the value pairs, the relationship between the voltage difference ΔV and the current I is a relation represented by a straight line with the slope ΔR thereof corresponding to an internal-resistance difference. Therefore, fault in the battery set can be determined from the magnitude of the slope ΔR computed by a least-squares method. Fault determination for a battery set is made more accurate because variations in electromotive force caused by charge-and-discharge patterns and by changes in temperature are canceled when the voltage difference ΔV is determined.
