Abstract
A method of estimating the temperature for cylindrical battery is expounded. Based on the simplified one-dimensional (1-D) thermal model and the Bernardi heat generate model, the finite difference method is used to calculate the internal and external temperatures of the battery. And different charge and discharge condition experiments are performed. Comparisons between the estimation results and measured results proved the accuracy of the model. The maximum estimation error is about 4.5℃. Using the measured external temperature of the battery, the internal temperature can be corrected. And the error is within 1℃.
