The day before the 2024 Beijing Auto Show, Weidu Technology, a new force in heavy trucks, released the first pure electric heavy truck, the first hydrogen fuel heavy truck and a new generation of full-wire chassis in Beijing.
In the subsequent overwhelming auto show reports, the appearance of Weidu Technology does not seem to have attracted much attention from the industry, but in the eyes of commercial vehicle news media, this is one of the most noteworthy new forces of heavy trucks (see the previous report "New Forces" Flowers are gradually dying out of charming eyes, 2024 new energy commercial vehicle players, who are you more optimistic about?). The reason is that the product positioning and core technology of Weidu Technology take a differentiated route, which is different from the speed leopard and not like Deepway, it takes a route similar to Tesla's semi truck, and compared with other new forces, Weidu Technology is not the first to launch products, but it is the most released products in one go, from hydrogen fuel cells to pure electric heavy trucks and full wire-controlled chassis.
Has been bored to build a car, a team of more than 130 people, engineers alone account for 100 people, and also take the engineer route of reed technology, compared with the new forces of commercial vehicles such as speed leopard, deepway, zero one, etc., can it take the lead in the track of new energy heavy trucks?
Please see the report from the commercial vehicle news media.
Most like Tesla Semi's new heavy truck force
Not long before the launch of the new energy heavy truck brand and new product launch conference of Weidu Technology, the commercial vehicle news media participated in the world premiere of the core technology of the speed leopard in Yulin, Shaanxi, coincidentally, in the latest release of the Ministry of Industry and Information Technology in the 382 batches of new car catalog, Weidu and the speed leopard are on the list, both declared pure electric tractors, the front and rear feet of the two new commercial vehicle forces, it is difficult not to let people compare their products, from which it can also be seen that the two start-ups have different development route orientations.
Let's take a look at the products of the speed leopard first, the first product of the speed leopard black diamond is aimed at the scene of bulk resource transportation, the typical inverted short scene is not so high for battery life, intelligent requirements, but more attention to energy consumption, efficiency, power, etc., so the speed leopard black diamond is not so radical in terms of appearance and performance index comparison, more practical, which also means that the cost is controllable and reduced. From the perspective of the four core selling points of the Black King Kong: extreme energy efficiency, not afraid of winter, super power and worry-free energy replenishment, it corresponds to the four core technologies it strives to build - distributed electric drive axle system, integrated thermal management system, 800V high-voltage power motherboard, and intelligent chassis domain control system, which is obviously more suitable for bulk cargo transportation.
Reed is different. When the spy photos of the new car were exposed, some people said that this is the Chinese version of Tesla Semi, from the appearance to the interior of the cab, from the product design concept to the application of advanced technology, Weidu is indeed like Tesla, and even does better in some indicators. This also stems from the positioning of reed pure electric heavy trucks, going high-end, focusing on a distance of about 600 kilometers, which allows reed to jump out of the current pure electric heavy trucks with a radius of about 200 kilometers for resources, ports, parks, etc., which is also the main market for various enterprises.
What are the technical highlights and advantages of the product
Let's take a look at the cab of the reed pure electric heavy truck, the entire center console in addition to the steering wheel, is 2 huge screens, almost no physical buttons, in the form of driving to take the concept of single driving, the same driving in the middle, electronic rearview mirror, released the car space, reached 8.2m³, the cab is equipped with dual-zone independent air conditioning, large canopy, optional bar, water dispenser, sink; The rear sleeper adopts a semi-recumbent sleeper, which is integrated with the rear passenger seat, and the car is equipped with an on-board TV, rhythmic atmosphere light, and on-board fragrance.
There are two world firsts for Weidu's pure electric heavy trucks: different from the design of the outside door and the rear door, Weidu adopts the electric sliding door design, which is the only one in the world, and it is also equipped with an AR-HUD on-board head-up display, which is also the first in the world. Therefore, Han Wen, the founder of Weidu Technology, is proud to say that this will be the most comfortable cockpit.
Looking at the parameters of the vehicle, it is equipped with a 729kWh battery and has a full load range of 670km for the CHTC-TT. It adopts 800V high-voltage platform, megawatt charging, 35min charging capacity can be used for the vehicle to drive 400km with full load, and the standard national standard charging interface can be expanded to CCS and CMS charging interface.
The vehicle adopts a large number of lightweight design, and the curb weight is 10,750kg; Up to four hairpin flat wire permanent magnet synchronous motors are used, with a continuous power of up to 680kW and a maximum drive power of 1040kW, and the MCU adopts SiC module, with a maximum efficiency of more than 99.7%, a 0-100km/h acceleration time of only 22s and a maximum speed of 120km/h under full load conditions. The chassis uses a double wishbone front independent suspension with 10 airbags to absorb shocks.
The thermal management system adopts AGS active air intake grille technology, and the first intelligent electrical box, which makes the load power supply configurable, diagnostic, and iterative, and realizes dual redundancy of the power supply; Standard CMS, 270° surround view + rear image, LDW, FCW, AEB, ACC, BSD, DOW, CSW, TSR, LKA, LCC, IHBC, MALSO, TPMS, ESC, DMS, can be said to be readily available, and software can be iterated to L3 and L4 high-level assisted driving; The Internet of Vehicles has voice control, remote control, digital key, fault diagnosis and early warning, maintenance reminder, SOS, fleet management, OTA, etc.
China, the United States and Europe are working at the same time
In the narration of the founder Hanwen, Weidu has many technologies that are the world's first, China's first, and the world's first in many indicators, such as the lowest drag coefficient, which is better than Tesla SEMI. Although they are all aerodynamically designed imitation bullet shapes, as latecomers and "rear birds", Weidu must have further optimized the shape, so that the drag coefficient of the pure electric vehicle model is only 0.2755, which is lower than the drag coefficient of 0.35 of domestic friends and the drag coefficient of 0.36 of Tesla in the United States.
For example, the fastest charging, the best energy consumption, the largest horsepower, etc., the newly designed frame can realize the free combination of building block battery energy storage installation and battery pack, and the dual-motor electric drive axle jointly built with Hande axle realizes the power module of the integration of drive and transmission to achieve high power and low loss output.
It can be said that the latecomer's Weidu has given full play to its latecomer advantage in the development concept and technology application. On the one hand, with the blessing of the contacts and resources accumulated by the founder Hanwen in the United States, it will enter the European and American markets faster than other new forces, on the other hand, it has a strong technical foundation and industrial chain supply chain of China's new energy vehicles, as well as the rich scenarios of China's largest commercial vehicle market.
According to reports, Weidu's first pure electric heavy truck has completed the test of multi-user, multi-scene and multi-road conditions in China, and will begin to conduct substantive road tests in Belgium, the Netherlands and France in Europe, and will soon start testing in the United States.
In the past two years, Weidu Technology has completed a $110 million Series B financing, with investors from HSBC, HITE Hedge Asset Management, Goodman Group, Baohe Innovation and GSR and other investors.
Conclusion:
So, compared with new forces such as Deepway, Speed Leopard, and Zeroone, as well as Jiefang, Sinotruk, Foton, XCMG, Sany and other car companies, who are you more optimistic about on the track of new energy heavy trucks, welcome to leave us a message in the comment area.
