7KW Electric Heater For EV,HEV
Description
Advances in Electric Vehicle Heating Systems
introduce:
Electric vehicles (EVs) have become very popular in recent years as they offer sustainable and environmentally friendly alternatives to conventional fossil fuel-powered vehicles. However, one of the main challenges facing electric vehicles is efficiently heating the cabin and maintaining optimal battery performance in cold weather conditions. With advances in technology, especially in electric passenger car heaters and automotive high-voltage coolant heaters, electric vehicle manufacturers have been able to effectively address these challenges.
1. Electric bus heater:
Electric buses are becoming more common in public transport systems around the world. Since these buses run on electricity, passenger comfort must be ensured by providing efficient compartment heating. Electric bus heaters are designed to use electricity from the vehicle's battery pack to heat the interior of the vehicle. It heats up quickly and distributes heat evenly throughout the cabin, ensuring passenger comfort during the colder months. Additionally, electric bus heaters are very energy efficient, minimizing the impact on overall battery capacity.
2. Automobile high pressure coolant heater:
In addition to cabin heating, maintaining an optimal operating temperature for batteries is also critical for electric vehicles. Automotive high pressure coolant heaters play a vital role in making this possible. These heaters use a combination of electrical resistance and circulating coolant to heat the battery cells, keeping them in the desired temperature range. By providing consistent heating, these coolant heaters increase battery performance, life and overall efficiency.
3. Electric bus battery heater:
Cold temperatures can significantly affect the performance and range of electric buses. To alleviate this problem, electric bus manufacturers have integrated battery heaters into their designs. Electric bus battery heaters prevent batteries from getting too cold, increasing their overall efficiency and extending their life. By maintaining battery temperature, these heaters can also reduce the energy required for charging, thereby optimizing the vehicle's range.
4. High-voltage electric vehicle PTC heater:
High voltage EV PTC (Positive Temperature Coefficient) heaters are another notable innovation in EV heating systems. PTC heaters are designed to quickly heat cabin areas, providing efficient and fast heating. They work by exploiting the inherent electrical resistance of certain materials, which increases with temperature. As a result, PTC heaters can self-regulate and maintain a constant temperature while providing comfort and energy efficiency.
in conclusion:
As the demand for electric vehicles continues to grow, it is critical to address the challenges associated with heating the cabin and maintaining battery performance in cold weather conditions. Advances in electric bus heaters, automotive high-voltage coolant heaters, electric bus battery heaters, and high-voltage electric vehicle PTC heaters demonstrate the industry's commitment to innovative solutions. With these technologies, electric vehicle manufacturers are improving passenger comfort, optimizing battery efficiency, and ensuring a seamless transition to a greener transportation future.

Product Features
The main performance features are as follows:
With compact structure and high power density, it can flexibly adapt to the installation space of the whole vehicle.
The use of plastic shell can realize the thermal isolation between the shell and the frame, so as to reduce the heat dissipation and improve the efficiency.
Redundant sealing design can improve the reliability of the system.
Design Principle
The PTC coolant heater module consists of PTC heating components, controllers and internal pipelines. The heating component is installed in the aluminum die casting, the aluminum die casting and the plastic casing form a closed circulation pipeline, and the cooling liquid flows through the heating body in a meander structure. The electrical control part is an aluminum die-cast body covered with a metal casing. The controller circuit board is secured with screws and the connector is directly attached to the circuit board.
The high-voltage part is inside the red frame, and the low-voltage part is outside the red frame. The high-voltage control unit and the low-voltage control unit contain circuit components such as microprocessors.
Product Application
This PTC coolant heater is suitable for electric / hybrid / fuel cell vehicles and is mainly used as the main heat source for temperature regulation in the vehicle. The PTC coolant heater is applicable to both vehicle driving mode and parking mode. In the heating process, electric energy is effectively converted into heat energy by PTC components. Therefore, this product has faster heating effect than internal combustion engine. At the same time, it can also be used for battery temperature regulation (heating to working temperature) and fuel cell starting load.
