NF 7KW PTC Coolant Heater 350V HV Coolant Heater 12V CAN
Description
As the automotive industry rapidly shifts to electric vehicles (EVs) equipped with high-voltage systems, there is a growing need for efficient heating solutions to ensure passenger comfort and optimal vehicle performance in cold conditions. High-pressure PTC (Positive Temperature Coefficient) heaters have become a breakthrough technology, providing innovative solutions for automotive high-pressure coolant heating. This blog discusses the importance, features and benefits of high voltage PTC heaters (HVCH) in high voltage electric vehicles.
1. Understand high voltage coolant heater:
High-voltage coolant heater (HVCH) plays a vital role in electric vehicles as it helps optimize battery performance, reduce energy consumption and ensure passenger comfort by providing instant heating in cold weather conditions. Conventional heating systems rely on waste engine heat, which is not feasible in electric vehicles. This requires efficient heating solutions like HVCH, which can effectively heat the coolant in the vehicle's high-voltage system.
2. Explore high voltage PTC heaters:
The High Voltage PTC Heater is a tip heating mechanism utilizing the PTC effect, where resistance increases with temperature. These heaters feature PTC elements made of highly conductive materials such as ceramics, which automatically adjust power output according to ambient temperature. As the temperature rises, the resistance increases, reducing the power output and thus preventing overheating. This remarkable feature makes HVCH a reliable and safe heating solution for high voltage electric vehicles.
3. Advantages of HVCH in high voltage system:
3.1 Efficient and fast heating: HVCH provides fast heating function, which ensures fast preheating even in cold weather. This high-speed heating minimizes energy consumption, allowing electric vehicles to optimize their range and overall efficiency.
3.2 Controllable power output: The PTC effect ensures the self-regulation of HVCH power output, making it highly flexible and efficient. This enables precise temperature control within the coolant, preventing overheating and reducing energy waste.
3.3 Safety: The high-pressure PTC heater adopts advanced heating algorithm to prevent excessive heat generation and give priority to passenger safety. The self-regulating feature ensures that the HVCH remains within a safe temperature range, eliminating the risk of fire or damage to the high voltage system.
3.4 Compact design: The HVCH has a compact design and can be easily integrated into high voltage systems. This space-saving feature is especially important for electric vehicles, where every inch counts.
4. Future possibilities of HVCH:
As the automotive industry continues to evolve, further advancements in HVCH technology are expected. Manufacturers are exploring opportunities to integrate HVCH with intelligent temperature management systems, employing advanced sensors and control modules. This enables improved energy efficiency, real-time temperature monitoring and individualized district heating for greater passenger comfort.
In addition, the integration of HVCH with renewable energy sources such as solar panels or regenerative braking may reduce the load on the vehicle's electrical system, thereby extending the overall range of electric vehicles.
in conclusion:
High-voltage PTC heaters (HVCH) are an important part of future vehicle heating systems, especially high-voltage electric vehicles. Their numerous benefits, including fast and efficient heating, controllable power output and enhanced passenger safety, make them game-changers for the automotive industry. As technology continues to advance, HVCH will undoubtedly play a vital role in ensuring a comfortable and efficient driving experience in electric vehicles, even in the coldest weather conditions.

Advantage
When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature. That is, under dry burning conditions without controller intervention, the calorific value of the PTC stone decreases sharply after the temperature exceeds the Curie temperature.
