Features & Benefits
- 100% Direct Plug-and-Play Fitment: Designed with heavy-duty BYD factory-matched four-point aluminum structural mounting legs, an integrated top-stabilized electronics housing enclosure, and an intelligently routed orange protective wave-conduit harness carrying the original terminal plug alongside a black low-voltage coupler for a seamless replacement workflow.
- Smart EV Systems Synergy: Interacts natively with BYD’s advanced vehicle control units (VCU) and battery management systems (BMS) to draw precisely modulated currents, maximizing the vehicle’s driving range while safeguarding lithium-ion traction packs during intense summer fast-charging.
- Robust Aluminum Body: Cast with an industrial-grade, hermetically sealed aluminum block shell bearing original laser-printed validation barcodes, engineered to rapidly dissipate high thermal loads and safely handle electric powertrain vibrations.
- Valve Port Security: Ships pre-sealed with factory-installed protective port sealing caps and factory-marked blue torque paint on chassis bolts to completely eliminate workshop dust, debris, and atmospheric moisture contamination until the exact moment of connection.
Crucial Installation Instructions
Warning: This compressor interfaces directly with a dangerous 350.4V high-voltage electric vehicle circuit. Installation must be executed exclusively by a certified electric vehicle (EV) technician. To protect the internal precision scroll mechanisms from immediate warranty-voiding mechanical failure, the entire vehicle refrigerant loop must be comprehensively flushed with professional cleaning fluid to extract old contaminants and residual fluids before mounting this new replacement unit.
