Experimental and Numerical Study on the Thermal Performances of Battery Cell and ECU for an E-Bike

In recent years, the traffic congestion, energy issues and environmental problems are occurred by increase in motor vehicles as well as population. The short and long range electrically operated vehicles like EVs (Electric vehicles) and LEVs (Light Electric vehicles) have been receiving much attention as a way to resolve these problems. Among these electric vehicle types, electric bicycle and electric scooters have the important components such as battery cell and ECUs (Electric Control Units). The component temperature is increased due to the heat generated by the continuous operation, which leads to decrease of the life cycle and performance. An experimental study was conducted to observe the effects of cooling performance of battery cell and heatsink case for ECU. Subsequently a numerical model was developed and cooling performance results of numerical study were validated by comparing it with experimental study. A new model is proposed with enhanced thermal performance for ECU heatsink.
