Modelling Improved Solutions to Reduce the Temperature in Lithium-Ion Batteries

Abstract

Lithium-Ion batteries are the most common energy storage devices used in electric vehicles. Battery heating management is a current topic, and modern solutions to reduce the temperature, as well as to avoid major or catastrophic defects. The 18650 model is often found in commercial models on the market. Using the the New European Driving Cycle (NEDC) standard that models the driver's behaviour with constant acceleration and braking, this work aimed to identify optimal battery cooling solutions on a Renault Zoe vehicle type. The two research directions focused on the variation of the cooling environment, respectively the variation of the positioning of the output/input plugs. The simulations were carried out in COMSOL Multiphysics starting from data provided by Model Advisor in MATLAB numeric computing environment.
