take a while. "
can take the pressure off " the immutable need for charging infrastructure, "
he said.
In another strategy to ease the transition from ICE to EV, David
Mountford, product manager for Dometic, briefly detailed his company's
work on a modulating, variable-cycle/output auxiliary heater
for EVs and other electrified vehicles. A common application, he said,
is for electrified transit buses, where the auxiliary heater is a moreefficient
solution for providing cabin heat than using valuable energy
from the vehicle's onboard battery pack.
Mountford said drawing electric cabin-conditioning heat from the
attributes in a range-extender layout - such as the
one Stellantis is preparing to deploy for the lightduty
Ram pickup - may be a good solution as the
propulsion transition evolves. Range-extender setups
vehicle batteries has an outsized detrimental effect on driving range.
Every kilowatt of heat output, he explained, equates to a drivingrange
reduction of approximately 1 km (0.6 miles).
" Let's get the net gains now, " Mountford said, of options such as
using low-carbon fuels and other " blended " propulsion strategies
rather than focusing solely on EVs. He said encouraging a variety of
technologies that can produce meaningful carbon reductions now is
preferable to " waiting for perfect. "
