NKH145 Diesel Range-Extended electric dump truck (REEV)

Economy & energy saving

The fuel is easy to get, compared with the traditional full fueltruck, significant savings infuel costs. The comprehensivesaving rate can reach 15-20%. NKE 145 series full electricwide-body dump truck save more than 80% of energycosts compared with fuel truck.

High-efficiency operation

The overall design is optimized to ensure the efficientoperation of the vehicle and improvethe working efficiency.

Cargo Body is optional

Base on Customers feedback, the rear door always get stuck by loading material always, and they demand the "V" type Hopper.

Strong personalized design capabilities can meet the needs of different customers.

Q1: Does the diesel range extender system affect power when battery is depleted?

A: When the range extender starts, it maintains motor drive characteristics. Under full load of 35 tons, the power output is stable. Tested on a plateau with an 8% slope, the power output fluctuation is less than 3%, automatically matching the optimal torque curve.

Q2: How to solve the winter range degradation of batteries?

A: Equipped with a dual-source thermal management system:

• Battery self-heating (starts at -30℃ within<15 minutes)

• Waste heat recovery device (recovers 40% of diesel engine waste heat)

Tested in Heilongjiang winter (-25℃), the range retention rate is 78%, better than industry average (<65%).

Q3: Impact of brake energy recovery on brake pad life?

A: Utilizes non-contact magnetic resistance braking technology, achieving over 85% energy recovery efficiency. Brake pad replacement cycle extends to 2.3 times that of traditional models (tested 120,000 km vs 52,000 km).

Q4: How much can overall operating costs be reduced?

Q5: Specific parameters of diesel consumption by the range extender?

A: Under intelligent SOC control strategy:

• Economy Mode: 1.8L diesel ≈ 10kWh (full load)

• Emergency Mode: 2.1L diesel ≈ 10kWh (continuous climbing)

Fuel saving rate compared to traditional diesel trucks is 38%-42%.

Q6: Who covers the cost of battery replacement?

A: A tiered warranty plan is provided:

• 8 years / 500,000 km capacity retention ≥80% (free maintenance)

• After warranty expiration, old battery trade-in subsidy: residual value ≥40%

Q7: How to prevent corrosion in acidic mining environments?

A: Optional titanium alloy cargo box components:

• Floor: 3mm titanium plate + 2mm rubber liner

• Side plates: Laser-clad WC-Co coating

• Hinges: Hastelloy C-276 material

Resists 10% concentration hydrochloric acid corrosion for ≥5 years.

Q8: Cooling assurance for continuous climbing conditions?

A: Intelligent thermal management strategy:

• Motor temperature >150℃ activates liquid cooling circulation

• Range extender water temperature >95℃ activates parallel cooling channels

• Cabin independent air conditioning system (electric compressor)

Tested on a 10km, 9% slope in Yunnan, no overheating alarms were triggered.

Q9: Can autonomous driving kits be installed?

A: Reserved modification interfaces:

• Lidar power supply: 48V/10A independent circuit

• Control signal interface: CAN bus expansion slot

• Hydraulic system modification: Electro-proportional valve replacement solution

L4 autonomous driving retrofit has been achieved in closed mining scenarios.
 Q10: How does REEV charge?

A: REEV supports various charging methods, including home chargers, public fast-charging stations, etc. Additionally, the range extender can automatically start to charge the battery when the battery level is low, ensuring vehicle range.

What is the range of REEV?

A: The pure electric range of REEV is typically over 150 kilometers, with a combined range of approximately 1,000 kilometers when fully charged and fueled, meeting the daily and long-distance driving needs of most users.
