FIELD: vehicles.
SUBSTANCE: invention relates to installed in the vehicle battery system and to its condition evaluation. Essence: the battery system contains a battery, a voltage sensor measuring battery voltage, a current sensor measuring current, flowing through the battery, and the electronic control device. Electronic control device is configured to evaluate the aging caused battery properties deterioration based on the open circuit voltage value, which is calculated based on the measured voltage value, and the total current value calculated when the battery charge level was in the hysteresis-free area.
EFFECT: technical result: enabling the battery deterioration simple and unambiguous evaluation.
