“…The possible reason could be that EVs are much more energy efficient when driving on interrupted urban routes than on uninterrupted freeway routes. Similar EV behavior has been mentioned by Zahabi et al (2013) and Chaudhry (2010), and recently observed by Knowles et al (2012). To further verify this point of view, we separated all of the data from 167 trips into two categories: in-city driving and freeway driving; then for each category of data, we calculated the energy efficiency using the total consumed energy divided by the total travel distance.…”

The paper analyzes three different, but similar class cars, two of them with conventional spark ignition (SI) engines, and one -hybrid (SI + electricity). Statistics of fuel consumption and mileage of several years are presented and analyzed, fuel price changes and provided exploitation costs. The analysis shows that in countries where are no privileges for the acquisition of hybrid cars or for operation (less parking or tolls, insurance or technical inspection price), the payback is hardly possible, because the hybrid car's price is about 2 times higher than that of a normal car, and fuel costs are reduced merely by about 20%. The results of the analysis show that payback of the hybrid car (at current fuel prices), in the best case possible after 0,73 million kilometers. Within annual mileage an average of 25 thousands km, the hybrid car will payback after 30 years!

“…Reduced driving range and battery performance at low ambient temperatures are a key market adoption barrier for battery electric vehicles (BEVs) [1]. This limitation is primarily attributed to increased energy and power demands from on-board battery pack at low ambient temperatures [2,3].…”

A New Consideration for Validating Battery Performance at Low Ambient Temperatures

Existing validation methods for equivalent circuit models (ECMs) do not capture the effects of operating lithium-ion cells over legislative drive cycles at low ambient temperatures. Unrealistic validation of an ECM may often lead to reduced accuracy in electric vehicle range estimation. In this study, current and power are used to illustrate the different approaches for validating ECMs when operating at low ambient temperatures (−15 • C to 25 • C). It was found that employing a current-based approach leads to under-testing of the performance of lithium-ion cells for various legislative drive cycles (NEDC; FTP75; US06; WLTP-3) compared to the actual vehicle. In terms of energy demands, this can be as much as~21% for more aggressive drive cycles but even~15% for more conservative drive cycles. In terms of peak power demands, this can range from~27% for more conservative drive cycles to~35% for more aggressive drive cycles. The research findings reported in this paper suggest that it is better to use a power-based approach (with dynamic voltage) rather than a current-based approach (with fixed voltage) to characterise and model the performance of lithium-ion cells for automotive applications, especially at low ambient temperatures. This evidence should help rationalize the approaches in a model-based design process leading to potential improvements in real-world applications for lithium-ion cells.
