Features & Benefits
-
- 100% Genuine Direct Fitment: Designed with heavy-duty BYD factory-matched four-point aluminum structural mounting legs, an integrated top-stabilized electronics housing enclosure, a rear-extended dual-core orange high-voltage protective insulated cable with a dark/light mixed coupling plug, and an upright yellow-white low-voltage sensor socket for a direct plug-and-play installation workflow.
- High-Endurance Power Synergy: Interacts natively with the vehicle’s control unit (VCU) and fleet battery management electronics to draw precisely modulated currents, maximizing daily driving range while safeguarding heavy-duty traction cells during high-load operations.
- Industrial Grade Resiliency: Cast with an industrial-grade, hermetically sealed aluminum block shell featuring a reinforced upper inverter housing, engineered to rapidly dissipate high thermal loads and safely absorb continuous chassis road vibrations.
- System Ingress Protection: 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 final assembly connection.
Crucial Installation Instructions
Warning: This compressor interfaces directly with a dangerous 394V 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.
