Public Electric Bus AC Semi Truck Air Conditioner Replacement For Commercial Vehicle

Introduction:
NEWBASE Fortress Electric Bus Air Conditioning System, engineered as the ultimate safeguard for modern electric fleets. By integrating automotive-grade safety protocols and multilayer protection mechanisms, this system establishes new industry benchmarks for operational safety in high-voltage environments, ensuring uninterrupted service while protecting passengers, drivers, and critical vehicle systems.

Safety Technology Highlights:

1. Intelligent Power Conversion:
   • Advanced DC-DC converter with triple-redundant protection (overvoltage, overcurrent, short-circuit) sustains reliable operation even at 65°C ambient temperatures, meeting stringent automotive functional safety standards (ISO 26262).
2. High-Voltage Heating Security:
   • IGBT-controlled PTC heaters incorporate self-diagnostic safeguards against abnormal voltage fluctuations, dry-burn prevention, and rapid shutdown mechanisms, eliminating thermal runaway risks.
3. Smart High-Voltage Distribution:
   • Pre-charge circuit enables soft-start power-on sequencing, distributing HV electricity through fused branches to prevent electrical arcs and load surges during ignition.
4. Electromagnetic Immunity System:
   • 360° Faraday cage shielding and equipotential bonding eliminate electromagnetic interference (EMI) risks, ensuring seamless coexistence with ADAS, telematics, and battery management systems in hybrid-electric architectures.
