Installation example
Vehicle installation environment requirements
A. The heater must be arranged according to recommended requirements, and it must be ensured that the air inside the heater can be discharged with the waterway. If air is trapped inside the heater, it may cause the heater to overheat, thereby activating software protection, which may cause hardware damage in serious cases.
B. The heater is not allowed to be placed at the highest position of the cooling system. It is recommended to place it at a relatively lower position of the cooling system.
C. The working environment temperature of the heater is -40℃~120℃. It is not recommended to install it in an environment without air circulation around high heat sources of the vehicle (hybrid vehicle engines, range extenders, pure electric vehicle heat exhaust pipes, etc.).
D. The permitted layout of the product in the vehicle is as shown in the figure above:
Advantage
A. Overvoltage protection: The entire vehicle needs to have an overvoltage and undervoltage power supply shutdown function
B. Short-circuit current: It is recommended that special fuses be arranged in the high-voltage circuit of the heater to protect the heater and high-voltage circuit related parts.
C. The entire vehicle system needs to ensure a reliable insulation monitoring system and insulation fault handling mechanism.
D. High-voltage wire harness interlock function
E. Ensure that the positive and negative poles of the high-voltage power supply cannot be connected reversely
F: Heater design life is 8,000 hours

Description
As technology in the automotive industry continues to advance, the need for efficient and reliable heating systems is becoming increasingly important to ensure optimal performance of electric vehicles. Two key components that play a key role here are the battery coolant heater and the high-voltage heater. In this blog, we’ll take a closer look at the importance of these components and why they’re critical to electric and hybrid vehicles.
Battery coolant heaters are designed to regulate the temperature of electric vehicle battery packs. They work by circulating coolant through the battery pack to keep its temperature within an optimal range. This is important because extreme temperatures can have a significant impact on the performance and lifespan of your battery. For example, in cold weather, a battery coolant heater prevents the battery from becoming too cold, resulting in reduced efficiency and overall capacity. On the other hand, in hot weather, a coolant heater prevents the battery from overheating, which can cause damage and shorten its life.
High-voltage coolant heaters, also known as high-voltage heaters, serve a similar purpose, but they are specifically designed to regulate the temperature of high-voltage components in electric and hybrid vehicles. These components, including electric motors, power electronics and charging systems, are critical to vehicle operation and are sensitive to temperature fluctuations. By using a high-pressure coolant heater, the temperature of these components can be controlled, ensuring they operate efficiently and reliably regardless of external conditions.
One of the main benefits of using battery coolant heaters and high-voltage heaters in automotive applications is the ability to precondition the vehicle. This means that the heating system can be activated remotely, allowing the battery and high-voltage components to reach optimal operating temperature before the vehicle is started. This is especially beneficial in cold climates, as it helps reduce stress on the battery and improves overall efficiency when driving in cold temperatures. In addition, vehicle preconditioning improves driver and passenger comfort by ensuring that the interior of the vehicle is at a comfortable temperature from the moment you enter the vehicle.
Another important aspect of battery coolant heaters and high-voltage heaters is their role in thermal management. Efficient thermal management is critical for electric and hybrid vehicles to ensure proper operation of vehicle components and maintain overall performance. By using coolant heaters, manufacturers can implement sophisticated thermal management systems that help regulate the temperature of the battery and high-voltage components, all of which help improve the overall efficiency and longevity of the vehicle.
In summary, battery coolant heaters and high-voltage heaters are essential components in electric and hybrid vehicles. They play a vital role in maintaining the temperature of batteries and high-voltage components, which is critical for optimal performance and longevity. As the automotive industry continues to evolve and electric vehicles become more popular, the importance of these heating systems will only continue to grow. As technology advances, we expect to see more sophisticated and efficient heating solutions, further improving the performance and reliability of electric and hybrid vehicles.

FAQ
1. What is an electric vehicle coolant heater?
An electric vehicle coolant heater is a component of an electric vehicle's thermal management system that helps heat the coolant in the vehicle's battery pack, motor, and other components. This helps optimize the performance and efficiency of electric vehicles, especially in cold weather conditions.
2. How does an electric vehicle coolant heater work?
Electric vehicle coolant heaters work by using power from the vehicle's battery pack to heat the coolant, which is then circulated through the various components of the electric vehicle's thermal management system. This helps maintain optimal operating temperatures for EV systems, improving their overall efficiency and performance.
3. Why are coolant heaters important for electric vehicles?
Coolant heaters are important for electric vehicles because they help ensure that the vehicle's battery pack and other components are operating at optimal temperatures. This helps extend the life of the battery pack and improves the overall performance and efficiency of electric vehicles, especially in cold weather conditions.
4. What are the benefits of using a battery coolant heater?
Using a battery coolant heater can provide a variety of benefits to electric vehicles, including improved battery performance and lifespan, improved overall vehicle efficiency, and increased driving range, especially in cold climates.
5. How does a battery coolant heater differ from an electric vehicle coolant heater?
