Electric Vehicles  

Range Problem 

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.  

EV Solution

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
