In the field of new-energy vehicles, battery pack performance directly affects the operational efficiency and safety of these vehicles, while the battery pack PTC heater plays a crucial role as a key component in ensuring stable battery operation.
The battery pack PTC heater—also known as a Positive Temperature Coefficient thermistor heater—operates based on the unique properties of semiconductor ceramic materials. When energized, its resistance value increases dramatically in a non-linear fashion as the temperature rises, automatically limiting the current flow and enabling self-regulated heating power, thereby preventing the risk of localized overheating. Compared to conventional heating methods, PTC heaters offer significant advantages such as automatic temperature control, enhanced safety and reliability, and superior energy efficiency. Moreover, they eliminate the need for complex, additional temperature-control devices, precisely maintaining the battery temperature within an optimal range. This ensures that the battery performance remains unaffected by low temperatures—avoiding reduced charge-discharge efficiency—and safeguards against potential safety hazards caused by overheating, which could lead to battery aging or even more serious risks.
In the field of new-energy vehicles, under winter’s low-temperature conditions, the battery pack’s PTC heater can rapidly boost battery temperature, ensuring both extended driving range and optimal power output. Meanwhile, in energy storage stations, it guarantees stable operation of the battery pack across a wide range of ambient temperatures, thereby prolonging the battery’s lifespan.
Zhengzhou Yusheng Technology specializes in the technical development of battery pack PTC heaters. Currently, their third-generation PTC heater can deliver a heating power of up to 25 kW, and its optimized design enhances both heat dissipation efficiency and safety.
The IGBT dissipates heat on the water channel, avoiding the impact of its installation position on cooling performance.
The PCB is mounted on the lower housing to prevent cable harnesses from being squeezed.
Although the battery pack PTC heater may seem like a small device, it plays an indispensable role in the new-energy vehicle sector—it truly serves as the "temperature manager" that safeguards battery performance.
Yusheng Technology is PTC Heater Manufacturer , independently developing and manufacturing various models of PTC electric heaters, widely used in new-energy commercial vehicles, fuel cells, and other fields. If you happen to have any requirements related to PTC heaters, Zhengzhou Yusheng Technology is undoubtedly a reliable choice for you.
