New Energy Power engine spare parts PTC heater 8115010-T412A

Adopting advanced ceramic PTC (Positive Temperature Coefficient) heating elements, this heater delivers exceptional efficiency with a thermal conversion rate of ≥98%, outperforming traditional resistance heaters by 15%. It achieves a maximum air outlet temperature of 65℃ within 30 seconds of startup, rapidly warming the cabin from -20℃ to 20℃ in 12 minutes—critical for NEV winter use. Beyond cabin heating, it also provides battery thermal management: the 5kW output maintains the battery pack temperature between 15℃-25℃, ensuring optimal charging/discharging efficiency (restoring 30% of battery capacity at -10℃ compared to unheated systems). The multi-channel air duct design ensures uniform heat distribution, eliminating cold spots in the cabin and battery compartment

Engineered with a comprehensive safety protection system, the heater mitigates risks associated with high-voltage heating. The PTC elements feature intrinsic temperature self-limiting—automatically reducing power when the surface temperature reaches 280℃, preventing overheating and fire hazards. It integrates over-voltage (input ≥500V), under-voltage (input ≤300V), over-current (≥16A), and short-circuit protection (instantaneous current limiting ≤20A) to avoid component damage. The high-voltage isolation (2500V AC) between heating elements and vehicle chassis eliminates electric shock risks. Additional protections include dry-burn prevention (via air flow sensor) and over-temperature shutdown (≥300℃), while the fault self-diagnosis function sends real-time alerts to the VCU, enabling proactive maintenance

Optimized for NEV energy economy, the heater features stepless power regulation (1kW-5kW) that adapts to real-time heating demands, reducing high-voltage battery consumption by 25% compared to fixed-power heaters. The built-in NTC temperature sensor (accuracy ±0.5℃) works with the HVAC controller to maintain cabin temperature within ±1℃, avoiding energy waste from frequent on-off cycles. When paired with the battery thermal management system, it prioritizes battery heating during cold starts, ensuring the battery operates in its optimal temperature range and reducing range loss by 15-20% at -10℃. The low standby power (≤5W) further minimizes energy consumption when not in use, contributing to longer driving ranges

Designed for efficient NEV maintenance, the heater features a user-friendly plug-and-play design. The high-voltage input (M16 waterproof connectors) and low-voltage control (DTM06-6P connectors) use tool-free locking mechanisms, simplifying wiring and cutting installation time by 40%. The 4-point mounting bracket matches standard HVAC unit holes, requiring only M10×30 galvanized bolts (grade 8.8) and a torque wrench (35-40N·m) for fixation. The heater’s aluminum alloy housing with integrated heat sinks ensures efficient heat dissipation and resistance to vibration (passing 500,000 cycles, ISO 16750-3). It achieves an IP67 waterproof/dustproof rating, withstanding rain and road debris. The maintenance-free design (no moving parts) ensures a service life of ≥8 years/200,000km, minimizing downtime for fleet operators
