3. Technical Highlights
3.1 Bottom Battery Layout: Space-Saving & Anti-Rollover
Compared with traditional “rear-mounted battery” designs, the Mengbate tractor adopts a chassis-mounted battery layout with significant advantages:
- Space Efficiency: Traditional rear-mounted batteries occupy 850mm of cargo compartment space (reducing cargo volume by 9% for 8×4 box trucks, equivalent to 5.5 m³ less load). The bottom layout avoids cargo space occupation and supports high battery capacity needs.
- Safety Enhancement: Lowers the vehicle’s center of gravity, greatly improving anti-rollover performance and overall driving safety (traditional designs have higher centers of gravity and poor stability).
3.2 Distributed Drive System: Weight Reduction & Efficiency Boost
The distributed drive system outperforms conventional direct-drive systems in key metrics:
- Efficiency: Increases drive efficiency by 14% (total efficiency reaches 94%).
- Weight Reduction: Cuts system weight by 23.6%, achieving a net weight reduction of 587kg (traditional direct-drive system: 1900kg; distributed system: ~1313kg).
- Energy Saving: Reduces overall energy consumption due to optimized drive logic.
3.3 High Reliability & Safety
The distributed drive system inherently incorporates advanced safety strategies, surpassing conventional direct-drive systems:
| Safety Feature | Distributed Drive System | Conventional Direct-Drive System |
| Traction Control (ASR) | Equipped with electric ASR; supports electronic differential lock for better passability on slippery/soft roads | No ASR function |
| Vehicle Stability Control (ESC) | Integrated ESC to improve cornering safety and passability on rainy/wet roads | No ESC function |
| Drive Redundancy | Independent drive for front/rear axles and left/right wheels; other components work normally if one fails | Single motor; total vehicle breakdown if motor fails |
| Brake-Drive Decoupling | Four-motor strong energy recovery; drive system acts as retarder to prevent brake overheating/thermal fade | No decoupling; no retarder function |
3.4 Safe, Efficient & Intelligent Battery Technology
Adopts CATL’s 3rd-generation swapable LFP battery modules, with industry-leading performance:
- Safety:
- Meets ASIL D safety requirements (industry average: ASIL B).
- Aerospace-grade thermal insulation and fire prevention design; “no-fire, no-leakage” performance (surpasses industry standards).
- Prevents thermal spread between battery modules.
- Capacity & Flexibility:
- Single battery module: 171 kWh; full set (3 modules): 513 kWh.
- Users can select battery capacity based on transportation scenarios.
- Performance:
- Temperature Adaptability: Operates in -35°C ~ 65°C (covers plateau, alpine, and high-temperature environments); 10% longer low-temperature range (-20°C) compared to industry averages.
- Charging & Swapping: 1 hour to charge from 20% to 100%; 5-minute battery swap (swap success rate >99%); supports 300A single-gun charging (-5°C startup, 15% faster charging from 20% to 100% at -20°C).
- Durability:
- Cycle life: 6000 charge-discharge cycles (3x that of previous generations; industry average: 2500 cycles).
- Energy density: 165 Wh/kg (3x higher than previous generations); battery + bracket weight reduced by 300kg (vs. 400kWh industry-standard batteries).
- Vibration resistance: Up to 3.74 g²/Hz (supports 500,000 km operation in mining areas; industry average: 1.44 g²/Hz for 100,000 km).
4. Warranty & Monitoring
- Provides transparent warranty for battery life.
- Real-time battery health monitoring to keep users informed of the system status.
