24V-750V 1-3kW High Voltage Coolant Heater PTC Heater for Electric Vehicle

The high voltage coolant heater is a core thermal management device tailored for modern new energy vehicles, widely applicable to electric passenger cars, commercial buses, trucks and new energy engineering machinery. It mainly works by electrically heating circulating coolant to provide stable and continuous heat sources for vehicle systems, undertaking two core functional modules: battery thermal management and vehicle body heating. In low-temperature environments, the heater realizes rapid battery preheating and constant-temperature maintenance, effectively improving battery activity, avoiding low-temperature power attenuation, and greatly enhancing vehicle cruising range and charging efficiency. In addition, it provides sufficient heat for cabin heating and windshield defrosting and demisting, eliminating frost and fog in cold weather, ensuring clear driving vision and improving riding comfort.
This product boasts outstanding structural and performance advantages. It features high heating efficiency and fast temperature response with low energy consumption, which effectively reduces vehicle energy loss and optimizes overall energy utilization. Adopting strict vehicle-grade design, the heater has excellent waterproof, dustproof and shock resistance, adapting to complex and harsh vehicle operating environments. Equipped with comprehensive safety protection systems including overheating, overcurrent, overvoltage and short-circuit protection, it effectively avoids equipment failure and potential safety hazards, ensuring long-term stable and reliable operation. Moreover, it has a compact and lightweight structure with high integration, which saves installation space and facilitates vehicle assembly and later maintenance.
With strong universality, the high voltage coolant heater is widely used in various new energy vehicles and special engineering equipment. It is the standard matching thermal management component for new energy buses, electric heavy trucks, logistics vehicles and sanitation vehicles. It can perfectly adapt to the thermal management needs of pure electric and hybrid vehicles, providing reliable low-temperature operation guarantee for vehicle batteries and passenger compartments, and has become an indispensable key part of new energy vehicle thermal management systems.
