An Open Circuit Voltage Model Fusion Method for State of Charge Estimation of Lithium-Ion Batteries

An Open Circuit Voltage Model Fusion Method for State of Charge Estimation of Lithium-Ion Batteries

The mapping between open circuit voltage (OCV) and state of charge (SOC) is critical to the lithium-ion battery management system (BMS) for electric vehicles. In order to solve the poor accuracy in the local SOC range of most OCV models, an OCV model fusion method for SOC estimation is proposed. Acc...
