4-9KW 800V High Voltage Thick Film Coolant Heater

Thick Film High-voltage Heater – Reshaping the Benchmark for New Energy Thermal Management, Adaptable to All-Area High-voltage Platforms

With the full arrival of the 800V high-voltage fast-charging era for new energy vehicles, traditional PTC heating solutions are no longer sufficient to meet the core requirements of high-end models for efficiency, safety, and long lifespan. The thick film high-voltage coolant heater, relying on advanced thick film screen printing and high-temperature sintering technology, revolutionizes the traditional heating structure. With a micron-level integrated heating core, it creates a new generation of high-voltage fluid heating solutions that are highly efficient, fast-response, highly safe, long-life, and lightweight, becoming the preferred core upgrade option for new energy thermal management systems.

Compared to traditional ceramic PTC coolant heater, this product achieves comprehensive performance innovation. Abandoning the heavy ceramic heating structure, the heating layer is thin and dense with extremely low thermal inertia, enabling millisecond-level rapid response and full-power output within 3 seconds. This completely solves the pain points of slow heating and long preheating times of traditional equipment, significantly shortening the vehicle's low-temperature start-up preheating time and effectively reducing winter range loss. The product is compatible with a full range of high-voltage platforms from 400V to 850V. Its ultra-high insulation and withstand voltage performance eliminates the risk of high-voltage breakdown and leakage, perfectly matching the stringent operating conditions of high-voltage fast-charging vehicles and solving the industry problem of traditional PTCs being unable to adapt to 800V high-voltage systems.
