Abstract

A hybrid vehicle battery life evaluating apparatus 1 includes an actual traveling measuring section 2 measuring, for each driving pattern, actual gasoline mileage data on a hybrid vehicle equipped with a battery as a power source, a test traveling storage section 3a storing test gasoline mileage data set for each driving pattern on the basis of a traveling test on the vehicle, a battery life evaluating section 5 comparing the measured actual gasoline mileage data with the test gasoline mileage data on the corresponding driving pattern to evaluate a degradation level of the battery on the basis of a value of a decrease in gasoline mileage set for each degradation level of the battery and transmitting information on battery degradation to a battery life display section 6, and the battery life display section 6 displaying the information on battery degradation.
