According to foreign media reports, with the continuous development of the trend of electric travel, vehicle heating also needs to be eco-friendly in the overall thermal management system of vehicles. In order to deal with the problem that the range of electric vehicles and hybrid electric vehicles will be shortened under low temperature, it is more and more important to introduce innovative heating concept for all types of vehicles. When the outdoor temperature is low, the electric or automobile may not have enough power to complete the planned trip. When the temperature drops, the performance of the power battery will also drop. Most importantly, when it's cold outside, the driver wants the inside of the car to be warm, which also consumes energy. Compared with summer, the range of winter car will be reduced by 25%. When the outdoor temperature drops to a very low temperature of - 20 ℃, the vehicle's range will be reduced by up to 50%. Therefore, Eberspaecher, an expert in thermal management in esringen, Germany, has provided a solution to this kind of challenge, and has launched a vehicle heater independent of the engine, which can not only realize the comfort function of the vehicle, but also an indispensable part of the vehicle thermal management system. As an automotive heater expert, Eberspaecher is able to provide the right solution for all types of vehicles and all requirements. The automobile fuel heater with integrated catalytic converter is suitable for hybrid electric vehicles. In winter, the internal combustion engine of hybrid electric vehicles will often start to generate heat and warm the environment inside the vehicle, which will consume fuel because of the low heat generation efficiency. The fuel heater, hydronic S3 INCAT, can prevent the engine from starting (to generate heat), and is independent of the engine, which can reduce fuel consumption and help to ensure a warm and comfortable interior space. The catalytic converter is fully integrated in the heater, which can almost eliminate carbon monoxide and hydrocarbon emissions, so it is a low emission heating scheme. In addition, the heater can also be heated so that its performance can be quickly restored. Eberspaecher's solution for pure electric vehicles is an ethanol heater, a carbon dioxide neutralization solution. The solutions offered by Eberspaecher are based on water heating and air heating. The ethanol heater can provide the necessary heat for the interior space and battery, so the battery does not need to provide energy. This is an eco-environmental solution, which will not affect the electric range of pure electric vehicles. For Eberspaecher, providing an eco-friendly heating solution is nothing new. The company launched its first ethanol heater as early as 2011. The new generation of ethanol heater (2kW) is based on airtronic 2 air heater and has been deployed in streetscooter's new work XL vehicle. Today, many hybrid and electric vehicles use Eberspaecher's high-voltage electric heater. This solution is specially developed for heating the interior space of hybrid and electric vehicles and regulating batteries. The heater adopts PTC (positive temperature coefficient) technology, which is very reliable and safe. Because PTC components only heat to the preset temperature, then the heater will automatically reduce power consumption, and the heater has self-control function, which can prevent overheating. At present, Eberspaecher Catem has produced about 1.5 million high-pressure heaters for electric vehicles and hybrid vehicles. In 2010, the complex PTC heater began to be produced in herxheim, Rhineland pfartz, Germany. Since 2018, Eberspaecher has started production in Tianjin, China.
