Problems solved by technology

That is, the charge / discharge balance of the battery is sufficient, but the battery is not fully charged due to insufficient charging efficiency therein
Therefore, when these situations are repeated, the charge capacity of the battery usually decreases with time (t)

Abstract

Disclosed is a battery management system and method of a vehicle. More specifically, the battery management system includes an alternator that supplies a battery and electronic equipment of a vehicle with electricity that is generated by a driving torque of the vehicle, a battery that supplies the electronic equipment with power that is charged by the alternator, a battery observer that observes a condition of the battery, a vehicle information collection portion that collects vehicle condition information according to driving of the vehicle, and a control portion that performs charging recovery of the battery by activating a battery refresh operation when at least one condition of a current accumulation value of the battery, a low SOC entry frequency, and a vehicle starting frequency satisfies a predetermined battery refresh condition.

Description

technical field [0001] The invention relates to a vehicle battery management system and a method thereof. Background technique [0002] Typically, a vehicle includes a battery that provides electrical power to electronic devices within the vehicle, and an alternator that generates electrical power to supply the generated electrical power to the battery and electronic devices. Due to continuously growing concerns about energy efficiency and environmental impact, environmentally friendly vehicles, such as hybrid electric vehicles (HEV) and electric vehicles (EV), utilizing high voltage batteries as a power source are becoming more popular as an alternative to traditional internal combustion engine vehicles. [0003] However, these high-voltage batteries must be frequently charged and discharged within a predetermined range, and the service life of the batteries is shortened due to deep cycling (a large amount of discharge). Also, the charging / discharging capacity of the batte...
