“…The performance of modern electric vehicle Li-ion battery cells depends on the working temperature and state of charge variation during the working loads [21,22]. In this paper based on the study of the operation of the system, a new design was presented as a combination of two cavities with heat transfer and the other with a thermal conductivity coefficient for the battery cooling system.…”

The most important components of electrical vehicles are the battery and the related cooling system. These subsystems play a major role in determining the overall electric vehicle performances. In this study, a novel cooling system with fluid in the battery cell is proposed, by which the energy storage system can be optimized through control of the temperature of the batteries. A sensitivity analysis is conducted considering the maximum temperature, the heat rate, the coolant temperature, and the geometry of the cavities. The numerical simulations show that the parameters for the trapezoidal compartment have an impact on the thermal performance of battery. An optimal geometry is proposed accordingly. It is concluded that for high values of Reynolds number for which the flow becomes turbulent, a decrease in the battery temperature can be obtained thereby avoiding thermal stresses.

“…Thermal characteristics of batteries and fuel cells are one of the focuses of research. The high or low temperature will cause the change of the internal structure of the battery, that is, the internal resistance of the Li-ion battery will have different effects on electrode materials, thereby affecting the capacity, cycle life, safety, and reliability of the battery [6]. Energy management strategy is also the core of hybrid power system.…”

Fuel cell hybrid electric vehicles are currently being considered as ideal means to solve the energy crisis and global warming in today's society. In this context, this paper proposes a method to solve the problem related to the dependence of the so-called optimal equivalent factor (determined in the framework of the equivalent consumption minimum strategy-ECMS) on the working conditions. The simulation results show that under typical conditions (some representative cities being considered), the proposed strategy can maintain the power balance; for different initial battery's states of charge (SOC), after the SOC stabilizes, the fuel consumption is 5.25 L/100 km.
