Abstract

The temperature of lithium-ion battery is critical for battery life-span and safety reliability. At present, the widely used temperature measuring method can only measure the surface temperature of the battery, but cannot measure the actual temperature inside the battery. Besides, the method is greatly affected by ambient temperature, and the accuracy is limited. To solve the above problems, we proposed a new noninvasive temperature measuring method based on magnetic nanoparticles for electric vehicle lithium-ion battery. At first, the mechanism of magnetic nanoparticles for battery temperature measurement was studied. Then, a temperature measuring model was established. Excitation and measurement system of AC magnetic field was built for temperature measuring experiments. The test results demonstrated that the proposed method could accurately measure the internal temperature of the battery.
