An Experimental Investigation of Electrical and Thermal Performance of Battery Pack for Zero Emission Vehicle

Abstract

A motor transport is a leading cause of the negative ecological situation and the excessive use of non-renewable resources. Increasing the volume of emissions from the operation of internal combustion engines and increasing consumption of hydrocarbon fuel are factors that stimulate the development of electric vehicles which are environmentally friendly and energy efficient. However, today electric vehicles are difficult to counter conventional cars in terms of cost and performance, determined mainly by characteristics and operating modes of traction battery packs. This article considers some topical issues related to the practical implementation of traction battery packs based on lithium-ion cells. The electric and thermal characteristics of the battery pack are considered by the authors in conditions of a discharge mode simulation. This is believed to be a the technical solution for the implementation of a modular battery pack, The present experimental investigations give qualitative and quantitative evaluation of the heat release of lithium nickel manganese cobalt oxide (NMC) cells and demonstrate the efficiency of the realized passive air cooling. This article partly fills the gap existing with regard to real (experimental) data on temperature conditions and heat release of NMC-cells in battery packs of electric vehicles.
