Method of controlling battery charging and discharging in a hybrid car power source
First Claim
1. A method of controlling battery charging and discharging in a hybrid car power source, the method comprising:
- a step to detect remaining capacity of batteries that supply power to a motor that drives the hybrid car; and
based on detection results,a step to control charging and discharging to keep detected remaining capacity within a pre-set first targeted control range when battery conditions are normal; and
a step to control charging and discharging to keep detected remaining battery capacity within a second targeted control range, which is narrower than the first targeted control range, when an abnormality is detected;
wherein when an abnormality is detected, the second targeted control range is set to include the remaining battery capacity detected at the time the range for controlling remaining capacity is switched from the first targeted control range to the second targeted control range, which is the remaining capacity at abnormality detection.

Abstract
The method of controlling charging and discharging in a hybrid car power source detects remaining capacity of batteries 1 that supply power to the motor 11 that drives the hybrid car, controls battery 1 charging and discharging to keep detected remaining capacity within a pre-set first targeted control range under normal conditions, and controls battery 1 charging and discharging to keep detected remaining capacity within a second targeted control range that is narrower than the first targeted control range when an abnormality is detected. Further, the method of controlling charging and discharging sets the second targeted control range to include the detected remaining capacity when the range for controlling battery 1 remaining capacity is switched from the first targeted control range to the second targeted control range at detection of an abnormality.
