Deterioration degree calculating apparatus and deterioration degree calculating method for a battery
First Claim
1. A deterioration degree calculating apparatus for a battery, comprising:
- a detector that detects plural state quantities of the battery;
a first calculator that calculates plural deterioration degrees based on the detected plural state quantities;
a storing device that stores contribution degrees each of which corresponds to each of the plural deterioration degrees;
a second calculator that calculates a total deterioration degree of the battery based on the deterioration degrees and the contribution degrees; and
a third calculator that calculates the contribution degrees based on the calculated total deterioration degree.

Abstract
A battery ECU includes a central processing unit (CPU). The CPU calculates plural deterioration degrees based on data input from a thermistor, an ammeter, and a voltmeter which detect state quantities of a nickel-hydrogen battery, and reads, from a memory, contribution degrees each of which corresponds to each of the calculated plural deterioration degrees. Then the CPU calculates a total deterioration degree of the nickel-hydrogen battery based on the deterioration degrees and the contribution degrees, calculates the contribution degrees based on the calculated total deterioration degree, and stores the contribution degrees in the memory.
