Current HVAC is Energy Intensive. Designed around combustion engine vehicles.
Range drops 20% for each 10°C decrease
New EVs use Low-e glass
Transparent, metal layer is added to reduce solar gain to lower cooling load in summer.
Controller provides high-voltage, pulsed power to the low –e conductive layer inside of glass.
Pulsing controls penetration depth of heat to just the interfacial layer, so that the surrounding environment isn’t heated.
One algorithm for Defrost.
One algorithm for Defog.
20X less energy than HVAC defrost/defog
