Battery control apparatus, vehicle, and battery control method

摘要

A battery control apparatus includes: a battery circuit in which a plurality of batteries are connected in series; a plurality of bypass circuits, each of which removes a corresponding battery from the battery circuit; a plurality of switches, each of which switches whether to connect a corresponding battery in series with the other batteries, or to connect the corresponding battery to a corresponding bypass circuit to remove the corresponding battery from the battery circuit; a deterioration detecting section that detects deterioration of each of the plurality of batteries; and a switch control section that controls the plurality of switches to remove, from the battery circuit, the batteries having greater deterioration and connects, in series, the batteries having smaller deterioration.

1. A battery control apparatus comprising:
a battery circuit in which a plurality of batteries are connected in series; a plurality of bypass circuits, each bypass circuit operable to remove a corresponding one of the plurality of batteries from the battery circuit; a plurality of switches, each switch operable to switch a corresponding one of the plurality of batteries between the battery circuit and the corresponding bypass circuit; a deterioration detecting section operable to detect deterioration of each of the plurality of batteries; a voltage detecting section that detects a voltage of the battery circuit; and a switch control section operable to control the plurality of switches to remove, from the battery circuit, each battery having a difference in deterioration from the battery of the plurality of batteries having the smallest deterioration that exceeds a predetermined value, and reconnect each battery having a difference in deterioration from the battery of the plurality of batteries having the smallest deterioration that exceeds the predetermined value when the voltage of the battery circuit becomes a predetermined voltage or less.
