Application of 30kW PTC electric heater in new energy special vehicles
In new energy special vehicles (such as pure electric mining trucks, sanitation vehicles, airport shuttle buses, etc.), the 30kW PTC (positive temperature coefficient) electric heater is a key component of the vehicle's thermal management. Its core application is to provide efficient and safe heating and specific functional heating.
The main application scenarios are as follows:
(1) Cab heating: Replacing the waste heat of the engine in traditional fuel vehicles, the PTC heater directly utilizes the power battery's electrical energy to quickly provide comfortable warm air to the cab, ensuring the driver's operating environment and safety in cold conditions.
(2) Power battery pack preheating: This is its key application. At low temperatures, the performance and charging efficiency of lithium batteries will drop significantly. The PTC heater uses circulating coolant to precisely preheat the battery pack, allowing it to quickly reach the optimal operating temperature range (usually 15-30°C), thereby ensuring the vehicle's range and output power, protecting battery health, and extending its lifespan.
(3) Other functional heating: According to special operation requirements, it can provide defrosting and defogging functions for rearview mirrors and windows, or provide antifreeze insulation for special equipment (such as the cleaning fluid tank and hydraulic system of sanitation vehicles).
The advantages of choosing a 30kW PTC are:
(1) High efficiency and energy saving: The electro-thermal conversion efficiency exceeds 95%, and the power can be intelligently adjusted according to demand, avoiding energy waste.
(2) Safe and reliable: The characteristics of PTC cause its resistance to automatically increase after heating, limiting the power. It has self-regulating temperature control and overheat protection functions, no open flame, and high safety.
(3) Compact structure: It is easy to integrate and install in the limited layout space of a vehicle.
In conclusion, the 30kW PTC electric heater is an indispensable solution for ensuring the normal operation, work efficiency, and driving comfort of new energy special vehicles in cold environments.
