“…It was extrapolated to create efficiency values below 1000 rpm at constant torque and was found that the effect of this change on cycle simulation results is marginal; therefore the efficiency below 1000 rpm was kept as the original 85%. The map based modelling approach is commonly used for the electric machine in BEVs [22]. There are two operating modes in the vehicle, namely motoring and braking.…”

Permanent AbstractThe development of battery electric vehicles (BEV) must continue since this offers the leading route towards a zero emission transport system. The fuel flexibility of the BEV offers the greatest potential to utilize power from renewable or low emission sources to be used in the transport system. However the limited range and high cost of the BEV remain important issues to be addressed. The battery is the element which strongly affects the cost and range of the BEV. The batteries offer either high specific power or high specific energy, but not both. This paper presents the modelling of a BEV which is used to study the potential for improvement in its energy efficiency. The battery model types have been discussed. The vehicle and other component models have been described. The choice of model parameters and the control strategy has been explained. The simulations have been performed on homologation and real world cycles for different scenarios. Results show significant potential for improvement in the energy efficiency of the BEV in real world usage by the utilization of a secondary energy storage device.

“…In a general study on electric vehicles Helms et al assume a 95% and 90% efficiency for the battery and the motor and inverter respectively [26]. In studies on electric vehicles it is common to assume a transmission efficiency of 95% [26,37].…”

Abstract:Previous research has focused on the use of heat pumps in electric vehicles, with the focus on recuperating heat from, normally, ambient and one thermal source on the vehicle. Here 5 potential thermal sources on a vehicle have been identified and thorough testing on the benefit of each source has been performed. The results presented suggest the motor, a thermal storage device, and cabin exhaust extraction should be used >80% of the time according to the scenarios tested, while battery heating and transmission heat extraction should be used subject to conditions on the ambient temperature and drive cycle.

“…Apart from material losses, design defects, and construction drawbacks, converter loss and motor loss are also heavily dependent on the chosen control strategies (Uddin and Nam, 2008). For the fixed-gear ratio transmission system adopted in the studied LSEV, the power efficiency is thought to be roughly equal to 0.95 (Hofman and Dai, 2010).…”
