| Abstract: | Safety of electrical vehicle and complexity of battery management system were influenced by nonuniformity characteristics of battery pack. Special tests were designed to analyze how current,SOC and temperature influence nonuniformity characteristics of a Ni-MH battery pack by the study of internal resistance battery model. Over-discharge characteristic of Ni-MH battery was modeled; a new method on how to determine the voltage sensor number of battery management system was proposed and validated by test data. |
