An Air Force Cooling of Lithium–ion Battery Thermal Management System for Heat Eliminating in Modified Electric Vehicle

This paper proposes the technique of modified minivan vehicle from Internal combustion Engine (ICE) to electric vehicle. The main equipment composed of 30 kW motor with converter and 16.92 kWh of NMC battery are calculated from weight and velocity requirement. The battery packing and heat generation evaluation by using principle of thermodynamic law and simulation model with solid works is illustrated. The air flow cooling system which consisted of 6 fans of 150 cubic feet/min, total flow is about 900 cubic feet/min are installed and experimented by operate the load at 70, 174 and 200 A respectively. The temperature increasing form heat generation of three case are 34, 60 and 72 Celsius. The protection system is determined for control the temperature within 60 degree for prevent thermal runaway.
