Abstract

The invention discloses a method, equipment, storage medium and device for detecting the state of charge of a battery. Compared with the existing method of directly estimating the state of charge of the battery through the ampere-hour integration method, in the present invention, the battery to be detected is obtained first. The current current, current voltage, current temperature and initial state of charge, and then determine the current voltage difference of the battery to be detected according to the current current, current voltage, current temperature and initial state of charge, and then according to the initial state of charge and current voltage difference Determine the current correction value, and finally determine the current state of charge of the battery to be detected according to the current current, the current correction value and the initial state of charge, so that the detection result of the battery state of charge is more accurate, and it overcomes the inability to accurately correct the battery charge in the prior art. The defects of the state of charge can be accurately detected to meet the needs of practical applications.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, equipment, storage medium and device for detecting the state of charge of a battery. Background technique [0002] At present, in hybrid vehicles, the 48V power battery is one of the core components, and its reliability and life are an important factor affecting the performance of the hybrid system. The situation poses a great challenge to the power battery management system. An accurate and reliable estimation method for the state of charge (SOC) can maximize the potential of the battery, avoid battery abuse, and improve battery life and hybrid system robustness. [0003] The ampere-hour integration method is currently the most widely used and the easiest SOC estimation method. During the working process of the battery, the charging and discharging current of the battery is integrated with the time, and then the dynamic SOC of the battery is estimated. The ampere...
