The development of electric vehicles
has been very rapid. Let us discuss how electric vehicles are heated
today. This is mainly related to electric car heating films. The following are some opinions from related industries.
Viewpoint 1:（From arl Young, M.E., Li-ion, supercaps, EVs ）
In
the larger Li-ion power packs that we design for high-performance
output, we provide liquid cooling/warming. Also, the electric motor will
have liquid cooling. The warm liquid can be channeled in two ways. When
the driver or vehicle occupants want warming-up, we channel the warm
liquid to their seats; otherwise, it goes to a heat-exchanger. Of
course, if you’re in slow moving traffic, your power pack and electric
motors will remain relatively cool; then we have resistive heating
elements to warm up the coolant a bit more. For ambient air warming, we
use quartz heating elements.
In
case, you were wondering about the warm liquid returning to the
batteries. It is very important to keep the batteries warm in cold
weather to avoid internal cell damages. So, we maintain 15–40C for our
power packs.
Viewpoint 2: (From Frank Schmitt Frank Schmitt, 20 years of EV tinkering)
Some
electric cars use a heat pump: basically an air conditioner that can be
reversed to pump heat into the vehicle rather than out of it. This adds
some cost, complexity, and weight to the air conditioning system.
Others
simply run power from the battery through a standard resistive heating
element. This uses considerably more power for the same amount of heat,
but is simpler, smaller, and cheaper.
Most
new electric cars can be programmed to preheat the cabin while still
attached to the charger, so the initial warm-up period doesn’t impact
range and the car is toasty warm before you even step in.

They
work the same way as any other electric heater. Some have a simple
heating element (like a toaster or a space heater), while others have a
heat pump (which is more complex but also more efficient).
In general, the most important thing is to choose efficient silicone EV battery heaters. Flyheaters
can provide customization and technical support for various battery
heaters. For more information about heaters, please visit the official
