How does the air conditioning system in new energy vehicles function?

 　　How does the air conditioning system in a new energy vehicle work? The air conditioning system in a new energy vehicle provides a comfortable environment inside the vehicle through functions such as cooling, heating, and ventilation.

　　In terms of cooling, the air conditioning system in a new energy vehicle is basically the same as that in a traditional fuel-powered vehicle, primarily consisting of components such as a compressor, condenser, expansion valve, and evaporator. The compressor in a new energy vehicle uses an electric compressor driven by high-voltage electricity from the power battery.

　　Within the condenser, the refrigerant transfers heat to the external air and liquefies, becoming a liquid. The liquid refrigerant flows through the expansion valve, where its temperature and pressure decrease, before entering the evaporator. Within the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the interior air and evaporates into a gas, which is then drawn back into the compressor for the next cycle, thereby continuously lowering the interior temperature.

　　For heating systems, there are currently two main types: positive temperature coefficient thermistor heaters and heat pump systems. PTC thermistor heaters increase temperature by applying electricity to the thermistor, causing it to generate heat. Some vehicle models use PTC thermistors to heat water, which is then sent to the heating core in the air conditioning ducts, and warm air is blown into the vehicle interior via a blower.

　　The ventilation system is a crucial component of the air conditioning system in new energy vehicles, responsible for introducing fresh air into the vehicle and expelling stale air. The ventilation system primarily operates in three modes: natural ventilation, forced ventilation, and combined ventilation.

　　How does the air conditioning system in new energy vehicles function? Currently, most new energy vehicles employ combined ventilation to enhance the efficiency of the ventilation system.

Why don’t all new energy vehicles use the same type of powertrain?

 　　Why don’t all new energy vehicles use the same type of powertrain? The core reason why new energy vehicles do not uniformly adopt a single powertrain is that there are significant differences between different technology routes in terms of performance, applicable scenarios and infrastructure requirements, and companies need to choose the optimal solution based on technical characteristics and market demand. 　　Pure electric vehicles use batteries as the only power source, with a simple structure and outstanding zero-emission advantages, but range and charging time are still bottlenecks. However, performance degradation in low-temperature environments and insufficient coverage of charging facilities still limit their application in long-distance travelling or inconvenient charging areas. 　　Plug-in hybrid vehicles combine a fuel engine with an electric motor to achieve pure electric driving for short distances through external charging, while relying on the fuel engin...

Where does the power for new energy vehicles come from?

 　　Where does the power for new energy vehicles come from? The power sources for new energy vehicles are diverse, primarily including electricity and hydrogen fuel. These energy forms are more environmentally friendly and sustainable compared to the petroleum used in traditional fuel-powered vehicles. 　　Electricity is the primary power source for new energy vehicles. Pure electric vehicles rely entirely on batteries and electric motors for propulsion, without an internal combustion engine. Batteries are charged at charging stations or using home chargers, and electric motors convert electrical energy into power to drive the vehicle. 　　Hydrogen fuel is another important power source for new energy vehicles. Fuel cell vehicles use hydrogen as fuel, combining hydrogen and oxygen through fuel cells to generate electricity. This process only produces water vapour and other harmless by-products. The batteries in fuel cell vehicles utilise this electricity to drive the vehic...
