Discharge Behavior Modeling of Traction lead-Acid Batteries

摘要：

In hybrid electric vehicles, one of the key tasks for the battery management system is to maintain the batteries in the proper range which can fulfill the requirement of energy flow. Considering the dynamic operating conditions of traction batteries, an equivalent circuit model is proposed to simulate electro-chemical characteristics of the battery. According to the dynamic equations of the circuit model, internal parameters can be induced through battery response under pulse current test. Different experiments are implemented exploring how the internal parameters vary with the depth of discharge, which is critical for the battery management to determine the energy conversion range.
