PTC heaters are divided by conduction method
(1) PTC ceramic heater based on heat conduction. It is characterized by a multi-layer heat transfer structure such as an electrode plate (electrical conductivity and heat transfer), an insulating layer (electrical insulation and heat transfer), a thermally conductive heat storage plate (some with thermally conductive glue) mounted on the surface of the PTC heating element, and the PTC element The heat emitted is transferred to the heated object.
(2) Various PTC ceramic hot air heaters that conduct convective heat transfer with the formed hot air. It is characterized by large output power, and can automatically adjust the blowing temperature and output heat.
(3) Infrared radiation heater. Its characteristics actually use the heat quickly emitted from the surface of the PTC element or the heat-conducting plate to directly or indirectly stimulate the far-infrared paint or far-infrared material that touches its surface to radiate infrared rays, which constitutes a PTC ceramic infrared radiant heater.
In winter, the battery life of new energy electric vehicles will generally shrink greatly, mainly because the electrolyte viscosity of the battery pack increases at low temperatures and the charge and discharge performance of the battery pack decreases. Theoretically: in an environment of minus 20 degrees Celsius, it is forbidden to charge the lithium battery (it will cause damage to the battery). Electric vehicles can be installed with car parking heaters to preheat the battery packs of new energy vehicles and keep them at normal operating temperature, so as to solve the problem of reduced endurance of new energy electric vehicles in low-temperature environments in winter and avoid low-temperature charging damage to the battery pack .
New energy pure electric vehicle battery pack heating system mainly adopts the following two methods:
Preheating heating solution 1: The fuel water heating heater installs water heating heaters for new energy electric vehicles, and heats the battery pack through heat transfer to reach the normal operating temperature.
The fuel of the plumbing heater can be fuel, diesel, formaldehyde, etc., with low fuel consumption and no obvious noise. In addition to preheating the battery pack of the car, it can also heat the cab of the new energy electric vehicle, reducing the power of the electric vehicle. Consumption, increase the service life of electric vehicles, and save a sum of battery replacement costs.
Preheating heater solution 2: new energy high-voltage electric heater
By installing PTC heaters in Xinneng electric vehicles, heat can be transferred to the electric vehicle battery pack to warm it up and keep it at normal operating temperature.
Regarding the heating system solutions of new energy electric vehicle battery pack preheating, cab heating, parking heating, etc., you can consult the official customer service. We will customize your own solution according to your specific needs.
