Abstract:Lithium-ion power battery charging process is closely related to its use efficiency and safety application. In recent years, how to shorten the total charging time and further improve the charging efficiency while reducing the energy loss has become the research focus and difficulty of lithium-ion power battery charging methods. Therefore, a charging optimization strategy of the lithium-ion power battery based on the step generalized predictive control is proposed in this paper. Moreover, combined with Constant Voltage charging method, the charging optimization strategy called Step Generalized Predictive Control Constant Voltage (SGPCCV) charging method is proposed. Simulation results show that the SGPCCV charging method can reach better charging results compared with the CCCV charging method.
