Apparatus and method for managing battery pack

摘要

The present invention discloses an apparatus and method for managing a battery pack, which can rapidly and accurately diagnose the coupling state of a bus bar to battery modules in the battery pack. In accordance with the present invention, provided is an apparatus for managing a battery pack having a plurality of battery modules and a bus bar coupled between the battery modules to electrically connect the battery modules, the apparatus comprising a coupling detection unit for detecting the coupling state of the bus bar to the battery modules; and a controlling unit for determining whether the coupling state of the bus bar has a defect on the basis of the coupling state detected by the coupling detection unit.

1. An apparatus for managing a battery pack having a plurality of battery modules and a bus bar coupled between the battery modules to electrically connect the battery modules, the apparatus comprising:
a coupling detection unit configured to detect the coupling state of the bus bar to the battery modules, wherein the coupling detection unit includes a voltage sensor for measuring the voltage at both ends of the bus bar; and a controlling unit configured to:
determine whether the coupling state of the bus bar has a defect on the basis of the coupling state detected by the coupling detection unit, anddetermine that the coupling state of the bus bar has a defect when a voltage at both ends of the bus bar measured by the voltage sensor exceeds a reference voltage range.
