It is reported that the "super flow IP" Tesla in the field of new energy vehicles, its electric truck product Semi is also reported to be mass-produced by the end of this year or early next year.

Is the air vent of the electric truck coming?
According to public data, Daimler has several trucks weighing around 18-36 tons, peak power of 250-500kw, battery capacity between 240-550Kwh, and Tesla Semi's cruising range of 480-800km, maximum load. Up to 36.29 tons, 647km can be driven in 30 minutes. This is not an order of magnitude more than a passenger car. Will the power battery ushered in the explosion of another sub-matching market with the electric truck air outlet?
We are no stranger to electric trucks.
Among the electric trucks of Daimler and Tesla, there are electric electric trucks that we are familiar with, namely electric light trucks.
For this type of vehicle, the development in China has indeed started and fallen in recent years. In recent years, the booming of e-commerce has made electric logistics vehicles seem to usher in the dawn of development. This point can be seen from the installed capacity of the battery: in 2017, the installed capacity of new energy special vehicles is 8.4GWh, and the proportion of electric logistics vehicles is about 98%, reaching 8.2GWh.
Then, the financial subsidies were declining, the battery cost was high, the cruising range was insufficient, and the charging facilities were lagging behind, etc., and the operation of the electric logistics vehicle was poured into the basin. Fortunately, the state issued relevant support policies in a timely manner, the industry enterprises adjusted in a timely manner, coupled with the declining cost of power batteries, the installed capacity of lithium iron phosphate batteries “turned overâ€, and the sales volume of electric logistics vehicles increased: in the first half of 2019, domestic pure electric logistics The cumulative sales of the car was 20,670 units, a year-on-year increase of 34.3%. Domestic enterprises such as Dongfeng Motor, Shaanxi Tongjia, Geely Commercial Vehicle, Nanjing Jinlong and other enterprises have done a good job in pure electric logistics vehicles.
The electric heavy truck seems to be quiet?
In fact, mainstream car companies at home and abroad have already laid out the layout of electric heavy trucks. For example, BYD proposed a strategy in 2015 to focus on the field of new energy heavy-duty special vehicles. Up to now, BYD has launched a number of electric truck products ranging in weight from 1.3 tons to 33 tons. According to the data, in the first half of 2019, BYD delivered a total of 2815 pure electric heavy trucks, ranking first in China.
Domestically, such as FAW, Futian, Dongfeng, China National Heavy Duty Truck, overseas, such as Volvo, Scania, Cummins, etc., also have products in the field of electric heavy trucks.
But the important factor that plagues the development of electric heavy trucks is still related to batteries.
As far as the battery is concerned, the electric heavy-duty truck has higher load capacity and higher requirements on the battery cruising range and light weight, and it is necessary to increase the driving mileage without reducing the effective cargo weight; meanwhile, the cargo transportation also requires the charging time to be obtained. Guarantee, so whether it can support fast charge is also one of the key factors for battery matching; of course, the most important thing is the cost of the battery system. In the case of excessive battery cost, there is no advantage in using electric trucks. .
It can be seen that battery performance and cost become the key point to control the normal operation of electric heavy trucks. In the current operation modes of many domestic and foreign heavy truck enterprises, electric heavy trucks are basically applied to specific application scenarios such as port traction, and the requirements for battery life and charging are not strict. In the future, if it is to be used in long-distance transportation, in addition to the construction of supporting charging facilities, low-cost, long-life, fast charging and other aspects need to continue to improve. In addition, the driving area spans the east, west, and north, and it is believed that the all-weather battery that is not sensitive to temperature will be more favored by heavy truck drivers.
As Jiang Zhenhua, a researcher at the Modern Logistics Research Center of the Institute of Economic and Social Development of Nankai University, said, the first thing that logistics companies use when using electric logistics vehicles is that they can safely come back when they go out.
Reading volume: Source: Battery Chinese Author: LOOThe machine is provided with such functions as automatic lifting, mixing, lowering, etc. A bin mixer and variety mixing bin of different specifications ,it can meet the mixing requirements of different batches and diversified varieties of products. It is an ideal machine for mixing in pharmaceutical plants. It is also widely used in such industries as medicine, chemical industry, food, etc.
Features:
â—This machine is a new model that our company has extensively absorbed and digested foreign advanced technology, successfully developed in combination with national conditions. Reasonable structure, stable performance, convenient operation, no dead corners, and no exposed bolts.
â—The rotating body (mixing bin) symmetry plane is at an angle of 30°to the rotation axis. The materials in the mixing bin rotate along with the rotating body and make tangential movement along the hopper walls, producing strong turning and high-speed tangential movement and achieving the best mixing effect.
â—It adopts PLC automatic control . It is provided with the infrared safety device and the discharging butterfly valve with the misoperation preventer to ensure safe production.
â—One machine can be equipped with bins of various specifications and quantities.
â—The machine effectively controls dust pollution and cross contamination, reduces loss of materials, controls material layering, optimizes production processes.
â—Meet GMP requirements.
Working Principle:
The machine is composed of two machine bases, rotation frame, rotation system, lifting system, control system, etc. Push the mixing bin into the rotation frame and complete the positioning. Start the control system to lift the rotation frame to the mixing height and clamp it reliably. The driving system will carry out automatic mixing according to the set time, rotation speed and other data. After the mixing operation is finished, the rotation frame will stop vertically, the bin will automatically fall to the ground, the machine will stop and process data will be printed. The bin is transferred to the next procedure.
