AI Technical Summary

Technical Problem

Existing technologies make it difficult to accurately determine the target SOC of the power battery in hybrid vehicles, which affects the energy management of the power battery and the driving experience.

Method used

By acquiring current relevant information, including altitude, slope, ambient temperature, battery temperature, and state of health (SOH), and combining it with preset tables and correction values, the lower and upper limits of the power battery's state of charge (SOC) are determined, thereby accurately calculating the target SOC.

Benefits of technology

It enables precise determination of the SOC of the power battery, improving the accuracy of energy management and the driving experience.
