BMW working on infrared heating system for EVsSeptember 20, 2012 by: Deepak
BMW is in the works to develop an infrared heating system for Electric Vehicles. Unlike conventional heaters which heat the air inside the car, which gets transferred to the occupants, BMW says the infrared heating system will be converted into infrared radiation, which will warm your body directly. And the system will work within one minute after being switched on.
The German automaker says the system would cut the energy use, which is much more in the traditional systems. BMW discussed about the system last week at Innovation Day. Thermal radiation will be released through the panels that would be placed in door panels and footwells.
The system is energy saving but when can the vehicles have it still remains the question. BMW is bringing a plug-in hybrid concept named Active Tourer to the upcoming Paris Motor Show.
Infrared heating surfaces emit “healthy” radiant heat.
Conventional heaters and air conditioners today heat the air inside the vehicle, which then transfers its heat to the driver and passengers. In contrast, in systems employing infrared heating surfaces, energy is converted into infrared radiation, which then warms the occupants’ bodies directly. The heating effect is operational only one minute after the system is switched on.
In addition, the heat generated by infrared heating surfaces is distributed without any need for drafts of air and is completely silent. In the field of vehicle heating systems, modern infrared heating surfaces are a new solution that not only promotes low power consumption but also provides a noticeable improvement in the passengers’ level of comfort.
Particularly when used in battery electric vehicles (BEVs), which are purely electrically-driven, in future infrared heating surfaces will yield gains in efficiency, since the electrical energy will be used to directly warm the occupants. Apart from rapidly warming the passengers, infrared heating surfaces can be used as an additional feature to create an agreeable, cosy climate within the vehicle.
Separate regulated circuits, analogous to seat heating, with which the occupants can individually set their own degree of comfort are another possibility. Since each passenger can be provided with his own individual heating system, it is also possible to selectively heat only those seats that are occupied and thus reduce energy consumption.
