State-of-charge (SOC) of the power battery is one of the important parameters of the electric vehicles. The influence of the temperature on the SOC can't be ignored. This paper proposes a SOC estimation method based on the Nernst electrochemical equation. Statistical theory is applied to gain a more accurate battery model by measuring less data. The parameters of the model can be fitted by multiple...
The state-of-charge (SOC) is a critical parameter of a Li-ion battery pack. Differences among in-pack cells are inevitable and can change the total capacity of a pack and the remaining available capacity. Because the traditional methods for the estimation of the SOC of a pack did not consider the difference among the cells and the impact of balance control, we developed a new method that accounts...
The State-of-Charge (SOC) is an important evaluation index for power battery systems in electric vehicles. To eliminate the effects of drift noise in the current sensor, a new working model that takes the drift current as a state variable is proposed for high-power Li-ion batteries. In conjunction with this result, a total available capacity expression that involves the temperature, charge–discharge...
An accurate estimation of State-of-Charge (SOC) for power battery pack is very important in the applications of electrical vehicles. Single cell model is not suitable for battery pack of m u Iti cells. Considering the imbalance characteristic of serial connected battery pack, a Vmin model is proposed. The minimal cell load voltage of the battery pack (Vmin) is used as the model measurement variable,...
