The technology deployed for lithium-ion battery state of charge (SOC) estimation is an important part the design electric vehicle management systems. Accurate SOC can forestall excessive charging and discharging batteries, thereby improving discharge efficiency extending cycle life. In this study, key technologies are summarized. First, research status modeling introduced. Second, main difficulties in model parameter identification batteries discussed. Third, development advantages disadvantages methods Finally, current problems prospects trends
