Precise product definition, to create a large number of exclusive electric heavy trucks
The global high-voltage platform integrates charging and swapping for efficient energy replenishment. It is equipped with the industry's first quasi-900V silicon carbide platform, with a maximum voltage of 876V, achieving faster charging speed. In the 20%-80% range, it only takes 48 minutes to charge 250 kWh, which saves 20% of the time compared with the 600V platform, while on the Super Leopard Super Charging Pile and the 1000V Universal Charging Pile of Special Calls, it only takes 36 minutes, saving 40% of the time.
Heavy-duty durability and worry-free operation. The full-stack self-developed through-type highly-integrated electric drive axle, equipped with a leaf spring suspension and a sturdy body that is more suitable for bulk transportation, ensures the vehicle's super durability and impact resistance. At the same time, it has industry-leading design indicators, selects more reliable round wire motors and oil-water mixed cooling solutions, and has a design life of 1.2 million kilometers, far exceeding the industry standard, realizing maintenance-free wheel ends throughout the life cycle and worry-free operation for life. The electric drive axle integrates a power take-off, which realizes the parking power take-off and driving power take-off at the same time, saving tens of thousands of yuan in additional installation costs.
Excellent power and leading performance. The full-stack self-developed high-voltage power system breaks through the power limitations of traditional electric heavy trucks. With a maximum power of 1175 horsepower and a continuous power of 540 horsepower, the Leopard Black King Kong not only far surpasses the fuel and existing pure electric models in terms of acceleration performance, but more importantly, it shows excellent ability in continuous high-speed climbing ability, and breaks through the continuous uphill climb speed of more than 60 miles for large heavy loads. With a full load of 49 tons, it can maintain 80 km/h on a 3% long-distance ramp and 60 km/h on a 4% ramp, demonstrating excellent transportation efficiency and energy-saving performance.
Big, super dexterous. The Super Leopard Black King Kong has the shortest wheelbase of a bulk electric tractor, only 3600 mm, bringing a minimum turning radius of 8.6 meters, realizing the agility of large vehicles. This design allows the heavy-duty truck to flexibly steer and turn in confined spaces, optimizing operational efficiency, reducing driver fatigue and ensuring efficient transportation in complex road conditions.
The center of gravity is lowered, and the safety is upgraded. Through the bottom battery design, the center of mass of the vehicle is lowered by 377 mm, which significantly improves the anti-tipping ability and driving stability. In the case of full load, compared with the fuel tank of traditional fuel vehicles, the height of the battery box of the Subao heavy truck has been increased by 60 mm, which effectively avoids collisions. Equipped with CATL's latest generation of lithium iron phosphate batteries for heavy-duty trucks, it achieves the benchmark battery PACK safety, and at the same time, the additional battery strengthens the protective frame and guard plate, which can effectively prevent bumps and flying stones in harsh environments, and effectively keep the battery warm.
