In the past 2021, we can call it the "first year of electric intelligence", in this year, the models of the old era began to be slowly eliminated by the market, including fuel-powered models, including only electric "cars". Of course, there are also car companies like Weilai, Weima, Xiaopeng, Nezha Automobile, Weima Automobile and other car companies that have ushered in a turning point in their destiny.
Of course, there is also such a traditional old-time car company that has completed its strategic rebirth, and it is Volkswagen. In the context of the continuous erosion of traditional car companies in the era of electric intelligence, Volkswagen, which seems to be "too big to lose", has become the world's first "old" car company to complete strategic transformation with the courage to break the boat, and they have not only successfully come up with the MEB intelligent pure electric vehicle platform, but also put into production a number of models such as ID.3 and ID.4 on this basis.
Under the strong offensive of the MEB platform and the new car-making forces, other car companies that have not yet built a core intelligent electric platform will be under pressure.
Among the new forces of car manufacturers, Nezha Automobile's style is quite low-key. After 7 years of accumulation, the development of Nezha Automobile has also entered the fast lane, and the sales volume in 2021 will exceed 7w units, ranking first in the new camp of car-making forces. While achieving explosive sales growth, Nezha Automobile has also ushered in a new breakthrough in technology.
Three highs and one good, shot extraordinary mountain and sea platform
Not long ago, Nezha Automobile officially released the full-stack self-developed intelligent safety car platform - Shanhai Platform, and the universal rate of model parts developed based on the "Shanhai Platform" can reach 80%, the research and development time is reduced by 8 months, and the cost can be reduced by 30%-40%, and finally the continuous iteration and continuous upgrading of product functions can be realized. The characteristics of "Shanhai Platform" can be summed up as "three highs and one good", high safety, high scalability, high intelligence and environmental friendliness.
Among the "three highs", the first high is high security. Safety is the basic attribute of the car, including the safety of the car body, information security, functional safety, and the battery safety that electric vehicles are particularly concerned about now. In terms of information security, Nezha Automobile has joined forces with the top 360 companies to create an automotive-grade information security platform. In terms of functional safety, even in extreme cases, Nezha Automobile can reduce the risk within a controllable range. In terms of battery safety, Nezha Automobile will start with the structural design and material design of the battery to eliminate thermal runaway.
The second highest is high scalability, in addition to the first Nezha S equipped with the "Shanhai Platform" to be listed this year, Nezha Automobile's future SUV or more models will be born from this platform.
The last one is high intelligence, with a focus on smart driving. The "Shanhai Platform" will gradually realize the full-scenario intelligent assisted driving scheme of high-speed road sections, low-speed road sections and urban road sections through the 1000TOPs calculation platform and 6 lidar sensors.
The above aspects are Nezha Automobile as a new force in car manufacturing has rarely mentioned before, from the perspective of consumers, Nezha Automobile is wearing a car-making new force shell in the sale of cost-effective pure trams, its intelligent elements are not rich. But in the future, with the emergence of the "Shanhai Platform", Nezha Automobile will also complete the "make-up class", even compared with the "Wei Xiaoli" established in the same period.
Take Nezha Automobile's first model, Nezha S, built based on the "Shanhai Platform", as an example, which uses Huawei's MDC computing platform to achieve 200Tops high computing power. At the same time, in terms of perception unit, the car is also equipped with 2 lidars, 5 millimeter wave radars, 12 ultrasonic radars, 13 cameras, high-precision positioning units and high-precision maps, etc., which can realize pilot assisted driving on high-speed and urban roads, as well as L4-level intelligent driving in some scenarios such as parking and remote summoning.
In addition, for the wireless data transmission technology required for vehicle OTA, the current "Shanhai Platform" also has reserves, and it is expected to evolve to a central domain convergence architecture by 2025, to achieve complete decoupling of vehicle actuators and computing resources, and to achieve seamless links with large-scale supercomputing platforms in the cloud.
At present, Xiaopeng's new medium-sized and large-scale SUV model based on the Edward platform is only equipped with 3 lidars, which shows that the "Shanhai Platform" has provided upgraded redundancy for subsequent higher-level intelligent driving. In the hash rate, the current WM M7 and WEILAI ET7 are only in the early 1000TOPs, and the "Shanhai Platform" is not lagging behind in this regard.
Vehicle system-level intelligent thermal management, breaking the bottleneck of low temperature
"Driving in a down jacket" is a joke by netizens about electric vehicles at low temperatures: new energy electric vehicles that originally have mileage anxiety, coupled with the squeeze of mileage on the air conditioning heating in winter, can really be described as worse. How to use energy on mileage, rather than heating, has become the most concerned problem of every electric vehicle manufacturer.
In response to this problem, fuel vehicles can recycle the heat of the engine for cockpit heating. In the traditional fuel vehicle, this idea and practice has become a matter of course. In fact, new energy electric vehicles can also do a good job of heat recovery, and even do more refined and intelligent. Nezha has made important attempts in this regard.
Nezha S is equipped with a new generation of self-developed HozonEPT4.0 constant temperature heat management system, which is an integrated heat management system based on a highly integrated water source heat pump. Different from the traditional split vehicle thermal management strategy, Nezha S adopts the first vehicle system-level intelligent thermal management strategy in China. The integrated design opens up the thermal management of the crew compartment, battery, electric drive, and electronic components to protect the performance and safety of the car. Realize the concentration of the physical part of all components and the centralized part of the component control part, and realize a 40% reduction in the number of pipelines, a 50% increase in reliability, and a 20% increase in cruising range.
At the same time, in order to get rid of the problem of "lack of heating" in winter, it is worth mentioning that the intelligent dual-zone air conditioner equipped with Nezha S can automatically calculate the wind direction adjustment mode based on the ambient temperature, electric drive temperature, battery cell temperature and other states, according to the temperature difference between the target temperature of the air conditioner/co-driver and the ambient temperature.
Nezha S, like the Tesla Model 3, samples the heating mode of the PTC heat pump. However, the traditional heat pump used in Model3 cannot be started below 10 degrees, and the colder the weather, the lower the efficiency of the air conditioner of the heat pump, and the worse the heating effect. Nezha S heat pump realizes intelligent and collaborative control of various components of thermal management through electric drive waste heat recovery, etc., and the overall energy efficiency is optimal. Under the outdoor ambient temperature of -18 °C and the external circulation condition, the outlet air temperature can reach 48 °C, at this time the COP of the entire system can reach more than 2.05, and a single heat pump can meet the heating requirements of the passenger compartment. In the process of driving at -20 °C, 40km/h, the 10 minutes in the car are raised to a comfortable level, showing excellent product quality. Han EV, Xiaopeng P7, etc. use PTC heating method, and PTC heating energy consumption is high at low temperatures, which has a great impact on endurance.
In extreme cold environments, battery activity decreases and battery life decreases. Nezha S battery thermal management system adopts "thermal management system active heating", "battery pack self-heating", "battery self-heating during discharge" and other multi-circuit multi-heat source optimization intelligent thermal management strategy methods to keep the battery in a comfortable working area and ensure the normal performance of the battery.
Under the current trend tide, only intelligent electric platform models are the most worthy of market recognition. Of course, Volkswagen MEB and Tesla's current platform models are seizing the opportunity advantage, but that does not mean that they will not have competitors in the future.
Recently, Nezha S finally completed a 3-month winter calibration test, which also means that Nezha S is methodically crossing the key node of mass production. As a member of the new car-making force, Nezha Automobile can make timely responses to the sensitive needs of users, and can also meet user needs through innovative technologies, compared with traditional car companies, the performance of efficiency and ability is Nezha Automobile's outstanding advantages. In the field of intelligence, the emergence of the "Shanhai Platform" is that Nezha Automobile has the confidence to compete with many new car-making forces, and it is also a booster for the upward brand of Nezha Automobile.
