Abstract
En 中文
Charge time has become one of the primary issues restricting the electric vehicle development. In order to counter this problem, an adapted thermal management system has to be set in order to reduce the internal thermal gradient, by knowing the surface and internal temperature responses of the battery. In this work a Pseudo 3D model is developed to simulate cell performance and internal states under various boundary conditions. Attention was paid not only to the core and non-core components, but also the experiments required to parametrize the thermal and electrochemical models (heat generation). Contrary to what can be found in the literature, the developed model constitutes an optimal solution in terms of calculation time and accuracy which allows the model to be embedded in an electric vehicle and have accurate data in real
