Detailed Introduction to Three-Electric System Technology Power Battery System: All variants employ lithium iron phosphate (LFP) batteries with exceptional thermal stability, extended cycle life and high inherent safety. The battery packs are available in side-mounted or rear-mounted configurations, delivering a low center of gravity (CoG) and balanced load distribution without encroaching on superstructure mounting space. The system operates reliably across a wide temperature range of -30℃ to 65℃, and is fitted with an active thermal management system (ATMS) to mitigate range degradation in cold conditions and ensure safe charging at high ambient temperatures. Drive Motor System: A high-power permanent magnet synchronous motor (PMSM) is adopted with high efficiency, low noise and rapid response. The motor integrates both traction and regenerative braking functions to recover energy during downhill driving and deceleration to extend driving range and reduce brake pad wear. With an IP67 rating, the motor is engineered to withstand the dusty, wet and high-intensity continuous operation conditions typical of sanitation vehicles. Electronic Control System: The system is equipped with a 4-in-1 or 5-in-1 integrated controller that consolidates the motor control unit (MCU), DC-DC converter, on-board charger (OBC), vehicle control unit (VCU) and other functional modules, enabling a compact package and low failure rate. It supports dual charging modes of DC fast charging and AC slow charging, and is compatible with public charging stations and dedicated charging facilities nationwide. |

Chassis Structure & Retrofit Adaptability High-Strength Frame: Vehicles rated at 18 tons are fitted with double-layer frame rails sized 250×80×7+4, whereas the 25-32 ton variants adopt heavy-duty frame rails of 300×90×8+6. The structure boasts excellent torsional rigidity, resisting cracking and permanent deformation under prolonged heavy-load service conditions. Front & Rear Axle Layout: A 6-ton front axle is standard, paired with 10-15 ton rear axles. Single-reduction and hub-reduction rear axles are optional configurations, capable of fulfilling heavy haulage, steep-gradient climbing and non-stop continuous operation requirements. Suspension System: Two suspension options are offered: multi-leaf spring suspension and air suspension. Combined with full-floating cab damping, the setup delivers superior ride comfort and stable operation of aftermarket superstructures. PTO & Retrofit Interfaces: Factory-reserved interfaces for power take-off (PTO), pneumatic circuits, wiring harnesses and hydraulic circuits come with standardized specifications. This design shortens retrofit cycles, ensures perfect component matching, and avoids any damage to the original OEM chassis structure. |
