Abstract

The most important parameters of the battery management system are the state of charge(SOC) and state of health(SOH). The traditional method of estimating the SOC and SOH is to take measurement of the discharge current and the open circuit voltage. This paper proposed a new method of predicting the SOC which based on the measurement of dielectric loss angel. The method originated in the speculation that different state of charge batteries has different internal electrolyte distribution. In order to validate our point of view, a lot of experiment was done and got a series of convincing data. The preliminary experiment demonstrated that the SOC of Lithiumion battery is in proportion to the Dielectric loss angle of internal medium to some extent.
