Abstract
<div class="section abstract"><div class="htmlview paragraph">Improving the overall thermal management strategy in electric vehicles can
directly or indirectly improve battery efficiency and vehicle range. The aim of
this study is to simulate and improve the performance of motor cooling lines
developed for an electric bus using 1D computational fluid dynamics models. In
the study, simulation studies were carried out for the 12-m EV Citivolt vehicle
of Anadolu Isuzu. Design parameters such as placement of flow lines and
component selection were decided thanks to 1D models developed. The design
obtained at the end of the study was supported by tests and experimental
studies. As a result, it was seen that the components in the line correctly
detected the flow rate and pressure losses with a maximum error rate of 8% and
an average error rate of 4.8%. Additionally, the components on the line were
added to the model via their own characteristic dp-Q curves. In this way, it has
been seen that these components, which contain complex flow lines, can be
represented with unique dp-Q curves.</div></div>
