Port short-haul - EAX(SUZHOU)TECHNOLOGY CO.,LTD.

Industry Introduction

Short-haul port haulage and transshipment within enclosed areas (such as terminal-to-yard and railway port-to-warehouse) are characterized by high frequency, heavy loads, fixed routes, and 24-hour operation. They are the core link in the "last mile" of port logistics. By 2025, fuel-powered tractors will still dominate (approximately 65%), but their high pollution, high costs, and low adaptability are becoming increasingly acute under the port green transformation policy.

Industry Pain Points

Huge fuel consumption

The fuel consumption of a fuel tractor is over 45L per 100km, and the average daily fuel cost for 300km operation is 1,080 yuan (oil price is 8 yuan/L), accounting for more than 35% of freight income.
Heavy maintenance burden

The average annual maintenance cost of the engine is 80,000 yuan, and the DPF after-treatment system needs to be cleaned every 5,000 kilometers (costing 3,000 yuan per time). The high-salt environment aggravates corrosion failures.
Frequent environmental fines

The average monthly fine for exhaust gas blackness exceeding the standard (Lingelmann>Level 1) is more than 2,000 yuan.
Inefficient energy replenishment

Refueling requires leaving the operation area, which takes 30-60 minutes per trip (including queuing for the trip), and the average daily effective operation time is reduced by 30%.
Exceeding carbon emissions standards

A single gasoline vehicle emits 120 tons of carbon dioxide per year and faces port carbon taxes and the "National IV Phase-out Order" (banned from entering the core port area in 2025).
Risk of brake overheating

Under frequent start-stop conditions, the temperature of the mechanical brake pad exceeds 300°C and the braking distance increases by 50%.

Solutions

Economic revolution

The full-cycle cost is reduced by 40%.
Energy consumption dropped sharply

The electricity cost is 0.3 yuan/km vs. 2.4 yuan/km for a gasoline car. You can save 630 yuan for 300 kilometers per day and 230,000 yuan per year.
Vehicle-battery separation reduces costs

Battery leasing reduces the purchase price of a vehicle by 30% (for example, the price of a Sany battery-swap tractor is RMB 680,000 vs. RMB 980,000 for a gasoline vehicle).
5-minute rapid battery replacement

The mobile battery swap station next to the construction site matches the high-frequency operation rhythm (CATL EVOGO case), and the energy recharging efficiency is 6 times higher than that of gasoline vehicles.
Uninterrupted power

Dual motors drive a peak torque of 4500N·m (such as Tebowka Power), enabling heavy-load starting 30% faster, eliminating loading and unloading delays.
Zero emission compliance

A single vehicle can reduce carbon emissions by 120 tons per year, is exempt from carbon tax and enjoys port subsidies (such as priority dispatch for green-licensed vehicles at Qingdao Port).
Braking energy recovery

(efficiency 30%-55%), reducing mechanical brake wear by 80%.
