PROBLEM TO BE SOLVED: To provide a battery condition monitoring system capable of accurately recognizing power consumption of an individual ECU.SOLUTION: In a battery condition monitoring system for a vehicle, there are plural control units which are included in pieces of electronic equipment for a vehicle and perform control of the pieces of electronic equipment for the vehicle. The control units are connected to an in-vehicle communication network. At least one of the plural control units includes a battery condition monitoring unit that monitors the condition of a battery which supplies power to the electronic equipment for the vehicle. The battery condition monitoring unit includes: a battery current value acquisition part that acquires a battery current value on which current consumption of the battery is reflected; a current consumption calculation part that calculates the current consumption of the electronic equipment for the vehicle on the basis of the acquired battery current value and the operating state of the electronic equipment for the vehicle; and a data table that stores the current consumption calculated by the current consumption calculation part in association with the corresponding electronic equipment for the vehicle or the operating state of the electronic equipment for the vehicle.
