Air Heater For Electric Vehicle

Name: Air Heater For Electric Vehicle
Brand: Nanfeng
SKU: 203718795

NF PTC Ceramic Air Heater is suitable for hybrid battery vehicles and is mainly used as the main heat source for temperature regulation in the car. The heating effect of the product is faster than that of the internal combustion engine. During the heating process, the electrical energy is effectively converted into heat energy by the PTC component.

Air Heater for Electric Vehicle

1、Product Introduction

Advantages of PTC:

1, compared to resistance wire heaters, it is more energy efficient and the heat is more stable.

2, PTC heaters can be made into an independent module, which is more convenient to arrange. And according to the space structure provided by the whole vehicle, it can be designed into a shaped shape, flexible arrangement and easy installation.

3, Compared with heat pump warm air system, the structure is simple and the cost is lower.

4, Mature technology, more suppliers, and more options available for the whole car factory.

5, Simple maintenance after failure, low maintenance cost. After-market replacement parts are widely available and easy to achieve quick replacement and repair.

Disadvantages of PTC:

1, large power consumption. Although PTC saves a lot of power compared to resistance wire, PTC is still a power consumer on electric vehicles. Take the ES8 for example, the PTC controlling the warm air in the front is rated at 5.5 kW and the PTC controlling the rear is rated at 3.7 kW. If both PTCs were to heat the interior of the car at their rated power, it would consume 9.2 kWh of electricity in an hour. Then for the ES8, which has a power battery capacity of 70 degrees, one hour is equivalent to consuming a few 10% of the electricity, which greatly affects the range.

The electric heater is too independent and it is difficult to use the heat of the whole vehicle in an integrated way. Although the electric car does not have an engine, there will be heat sources after walking, such as the mechanical and electrical efficiency losses of the motor, the electrical efficiency losses of the battery, and the mechanical efficiency losses of the gearbox, all of which are basically converted into heat, which can actually be used in a comprehensive way to provide a heat source for the warm air. But warm air systems that use individual PTC heating are more difficult to realise as an intelligent thermal principle system.
