BATTERY PACK CONTROL APPARATUS
First Claim
1. A battery pack control apparatus comprising:
- a first monitoring device connected to a first single battery cell of a battery pack to monitor a state of the first single battery cell;
a second monitoring device connected to a second single battery cell of the battery pack to monitor a state of the second single battery cell;
a third monitoring device connected to a third single battery cell of the battery pack to monitor a state of the third single battery cell;
a battery pack control device that controls a battery capacity of the battery pack by producing a command signal;
a first communication device having an electric insulating quality provided between the third monitoring device and the battery pack control device such that the third monitoring device receives the command signal from the battery pack control device through the first communication device;
a second communication device having an electric insulating quality provided between the first monitoring device and the battery pack control device such that the second monitoring device receives the command signal from the battery pack control device through the third monitoring device, and the first monitoring device receives the command signal from the second monitoring device and the first monitoring device sends a detection signal to the battery pack control device through the second communication device; and
a first electric power consuming device that consume an amount of electric power at a single battery cell connected to the second monitoring device, the amount of electric power corresponding to a communication occurring at the second communication device.

Abstract
A battery pack control apparatus is provided with first, second and third monitoring devices, a battery pack control device, first and second communication devices, and a first electric power consuming device. The monitoring devices are connected to the single battery cells of a battery pack to monitor a state of the single battery cells. The battery pack control device communicates data related with the third monitoring device through the first communication device having an electric insulating quality and with the first monitoring device through a second communication device having an electric insulating quality. The second monitoring device communicates data with the first and third monitoring devices. The first electric power consuming device consumes an amount of electric power at a single battery cell connected to the second monitoring device. The amount of electric power corresponds to a communication occurring at the second communication device.
