Current automotive sector is ruled by energetic consumption , especially in Europe. Vehicles have to pass precisely defined cycles on roller bench or on open road in order to measure their energetic consumption as accurately as possible. Cycles are technical processes evaluating parameters of the car while it is being driven, whether on a roller bench with robots or on open roads with real humans. Some are official and validate vehicle consumptions, others are intern to car manufacturers and evaluate more specific parameters. Recently introduced, WLTC aims to evaluate energetic consumption. It is even more necessary for Battery Electric Vehicles (BEV) as their autonomy is a key factor for customers. As Battery Electric Vehicles are quite new, many improvements are to be made by car manufacturers, especially regarding their autonomy, their energetic consumption and their performances. Even if WLT-Procedure is mandatory to be studied, some intern cycles evaluating specific parameters can lead to a global improvement of the vehicle. As these cycles are not official ones, their parameters can vary between tests, therefore results can lose some of their interest. The aim of this master’s thesis is to study the need of thermal-management in future Battery Electric Vehicles, and then to work on most interesting cycles in order to evaluate the thermal-management of current vehicles. This thesis deals with the interest of thermal-management for Battery Electric Vehicles, with the way to evaluate it and the parameters to measure while processing the cycle. From 52 cycles, 20 cycles have been highlighted and defined to evaluate correctly thermal-management. Temperatures and slopes have been defined so the cycle is as representative as possible, and instrumentation is under discussion. The involved master’s thesis is based on bibliographic research and on Renault Thermal-Management Working Group results.
