Description

As technology continues to evolve, our reliance on fossil fuels is gradually being replaced by more sustainable and efficient alternatives. In the field of automotive engineering, this shift is highlighted by the emergence of electric vehicles (EVs) as a viable transportation option. As electrification grows, advanced systems are needed to ensure optimal performance, especially in cold climates. One of these revolutionary systems is the electric coolant heater, also known as the high-voltage PTC heater, which not only improves vehicle comfort but also plays a vital role in battery efficiency.

Learn about electric coolant heaters

Electric coolant heaters, often called high-voltage PTC heaters (positive temperature coefficient heaters), are an indispensable component in electric and hybrid vehicles. Its main function is to provide warmth to the cabin in cold weather conditions. Unlike conventional heaters that rely on engine waste heat, electric coolant heaters operate independently using electricity from the vehicle's battery or charging system.

How does an electric coolant heater work?

The coolant electric heater uses advanced technology and uses PTC heating elements to generate heat. PTC refers to a material with a positive temperature coefficient, that is, its resistance increases with temperature. This unique feature allows the electric coolant heater to self-regulate its heating output, ensuring consistent warmth without overheating.

When activated, the electric coolant heater draws electricity from the vehicle's energy source and directs it to the PTC element, which begins to heat. As the temperature increases, the resistance of the PTC material increases, limiting the current that can flow through it. This process effectively maintains a consistent and safe heating output, preventing any risk of overheating.

Advantages of EV coolant heaters

1. Improved vehicle comfort: One of the significant advantages of electric coolant heaters is their ability to quickly heat the cab, providing instant comfort to the occupants even before the conventional engine has warmed up. This eliminates the frustrating waiting times often associated with traditional heating systems, ensuring a pleasant driving experience from the moment you step into the vehicle.

2. Reduce battery consumption: Unlike traditional heating systems that rely on engine waste heat, electric coolant heaters operate independently, consuming electrical energy from the vehicle battery or charging system. However, modern electric coolant heaters are designed to be highly energy efficient, minimizing impact on the entire battery range. This efficiency allows EV owners to stay warm without compromising the vehicle's overall performance.

3. Environmentally friendly: Because electric coolant heaters rely entirely on electrical energy, they produce zero direct emissions. This sustainability advantage aligns with the larger goal of reducing our carbon footprint and moving to green modes of transportation. By choosing an electric heating system like an electric coolant heater, drivers are actively contributing to a cleaner, more sustainable planet.

4. Improve battery efficiency: Cold weather can significantly affect the performance of electric vehicle batteries. Extreme temperatures can reduce its efficiency and limit its range. However, an electric coolant heater can solve this problem by preheating the battery before use. Electric coolant heaters ensure optimal performance by keeping battery temperatures within an optimal range, resulting in efficient energy flow and extended battery life.

in conclusion

The electric coolant heater represents a major breakthrough in automotive heating technology with its high performance and environmental protection. As electric and hybrid vehicles increasingly dominate the road, this innovative system provides unparalleled passenger comfort without compromising energy efficiency. With enhanced battery performance and reduced carbon emissions, electric coolant heaters demonstrate progress towards a sustainable future. The adoption of this technology marks a substantial step towards achieving a greener transportation system and improving overall vehicle performance.

Note

The PTC coolant heater should be placed after the water pump;
ThePTC coolant heater should be lower than the height of the water tank;
The PTC coolant heater should be placed before the radiator;
The distance between the PTC coolant heater and the permanent heat source at 120°C is ≥80mm.

Principle: If there is gas in the waterway, it is necessary to ensure that the gas in the waterway can be discharged to ensure that there are no bubbles floating inside the heater (that is, it is forbidden to install the heater inlet and outlet downwards).
