Abstract
One of the reasonable possibilities to investigate the battery behaviour under various temperature and current conditions is the development of a model of the lithium-ion batteries and then by employing the simulation technique to anticipate their behaviour. This method not only can save time but also they can predict the behaviour of the batteries through simulation. In this investigation, a three-dimensional model is developed to simulate thermal and electrochemical behaviour of a 13Ah lithium-ion battery. In addition, the temperature dependency of the battery cell parameters was considered in the model in order to investigate the influence of temperature on various parameters such as heat generation during battery cell operation. Maccor automated test system and isothermal battery calorimeter were used as experimental setup to validate the thermal model, which was able to predict the heat generation rate and temperature at different positions of the battery. The three-dimensional temperature distributions which were achieved from the modelling and experiment were in well agreement with each other throughout the entire of discharge cycling at different environmental temperatures and discharge rates.
Highlights
Lithium-ion batteries are one of the most developing categories of batteries on the market these days because of their high energy density and capacity
The temperature distributions of the battery cell were determined as a function of time at of the uttermost of could the battery is confined at overall low current rates
A procedure was used to simulate the thermal behaviour of a lithium-ion battery at different current rates and environmental temperature
Summary
Lithium-ion batteries are one of the most developing categories of batteries on the market these days because of their high energy density and capacity. Notwithstanding, to the author’s best knowledge, only very few publications [13,14,15] are available in of the lithium-ion battery [12] This was according to the modelling outcomes of current density and the literature that discuss the thermal simulation of lithium-ion batteries by considering all of the the potential distributions. 2.
