Tech paper holds keys to
comfortable vehicle interiors
The global adoption of battery
and hybrid electric vehicles (EVs)
continues to grow, with
consumers and governments
hopeful that a shift toward more
sustainable transportation will
help reduce harmful particulate
emissions produced by internal
combustion engines (ICEs). With
increasing environmental
regulations implemented by the
U.S. Environmental Protection
Agency (EPA) and the National
Highway Traffic Safety
Administration (NHTSA) on
light-duty vehicle greenhouse
gas emissions, along with rising
fuel and maintenance costs, lastmile
delivery fleets are
encouraged to make a rapid shift
towards electrification.
The SAE technical paper titled
Modeling Climate Control Loads
and the Impact on Vehicle Range
for Last-Mile Electric Delivery
Trucks in Cold Climates
addresses that topic, as can be
read in heavily abbreviated form
below.
Limited by current battery
capacity and scarcity of
charging stations, range anxiety

Cabin temperature, ambient temperature, vent air speed.
remains a major concern for battery electric vehicle
(BEV) consumers, which would naturally extend to
prospective fleet operators considering
electrification. As with any passenger vehicle, BEVs
require cabin climate control for passenger thermal
comfort. As one of the major auxiliary energy
devices, the load of a heating and cooling system
can have substantial negative impact on a vehicle's
energy efficiency and driving range]. Thus,
quantifying the impact of temperature-correlated
changes in auxiliary loads on vehicle range is critical
for decision making in the context of vehicle routing,
charger placement optimization, and fleet
electrification in different climates.
