The major challenges associated with the heavy-duty segment are: (i) greater emphasis on economic viability, (ii) reluctance to take on risk associated with new technologies, and (iii) numerous diverse applications that preclude a one-size-fits-all approach to hybrid-electric powertrain design.
In addition, more than 30,000 all-electric buses have been sold in China, making the country the world's leader in the heavy-duty segment.
In the heavy-duty segment, China is the world's leader, with more than 30,000 all-electric buses sold through December 2014.
The slow down in sales that took place in the French EV market during the first half of 2014, allowed Norway, with 18,649 new all-electric vehicles registered, to end 2014 as the top selling European market in the light-duty all-electric segment, and France ranked second.

For designing 2-D straight PSW, the propagation dependence on the segment period, duty-cycle, etc. is investigated numerically.
The designs have been analyzed in view of the effect of change in their cladding parameters, such as refractive index contrast, air filling fraction (denoted by normalized air hole diameter), duty cycle of the segments, and core cladding interface.

Norway ended 2014 as the top selling European country in the light-duty all-electric market segment, with 18,649 passenger cars and utility vans registered.
