    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.
