Research State of Charge Estimation Tactics of Nickel-Hydrogen Battery

摘要

The battery state of charge (SOC) is an important parameter for the electrical vehicle. Its estimation is an important function of the electric vehicle battery management system. In this paper, definition of SOC is discussed; fundamental characteristics are also introduced. Many kinds of estimation tactics of SOC are described at the moment. The advantages and disadvantages of these methods during applications are given. Influence factors are analyzed at last.
