Price Trend Analysis of Tesla Model Y

Recently, Tesla’s Model Y has continued to sell well in the global market, showing its potential as one of the hottest models this year. According to statistics, as of September this year, the sales volume of Model Y has exceeded 500,000 units, which undoubtedly verified its strong appeal among global consumers.

Price differences in different regions

According to Tesla official website, the price difference is significant around the world. Xiao Lei pointed out that Singapore is one of the highest-priced markets in the world, and the basic price of Model Y is S $142,471 (about RMB 747,183), excluding taxes. In contrast, Chinese mainland is the cheapest market in the world. After the price reduction, the price of Model Y has dropped to 288,900 RMB, which is amazing compared with the Singapore price. This gap is mainly due to the tax policies and market control strategies of various countries, such as Singapore’s high tariffs and automobile growth control measures.

In China, due to the vigorous development of the new energy vehicle market, overseas brands such as Tesla enjoy policy support, and their prices are relatively low. However, with the rise of local new energy brands such as BYD, Weilai and Ai ‘an, the market competition is becoming more and more fierce. Tesla needs to constantly adjust its strategy, such as launching new models and promotional activities, to maintain its market share.

Tesla’s Challenges

Although Tesla takes the lead in the new energy vehicle market, its competitiveness is gradually facing challenges with the slowdown of product update. With the continuous emergence of new products from other brands, Tesla needs to accelerate the pace of innovation and provide more competitive products in order to gain a foothold in the increasingly fierce market competition. In order to maintain market popularity, Tesla recently launched two new car paint colors: Fast Silver and Midnight Crimson, but this is only a short-term strategy. In the long run, a strong product line is the key to maintaining competitiveness.

Generally speaking, the price trend of Tesla Model Y reflects the global market demand and policy impact, and also indicates Tesla’s future challenges in the field of new energy vehicles. In the face of fierce competition in the market, Tesla needs to constantly innovate and launch competitive new models to cope with future market changes.

The CX6672 graph data transmission module empowers the data link of the new generation UAV.

UAV data link is an important part of UAV system, and it is the link between aircraft and ground system. UAV data link can be divided into uplink and downlink according to transmission direction. Uplink mainly completes the sending and receiving of remote control instructions from ground station to UAV, while downlink mainly completes the sending and receiving of telemetry data (flight control) and video images (image transmission) from UAV to ground station, and uses uplink and downlink for ranging according to the transmission of positioning information. The performance of data link directly affects the performance of UAV. According to the time and function, the UAV data link is divided into three stages:

The first stage: data transmission, which is mainly used for data transmission between flight control and ground stations. The main purpose is to adjust parameters, telemetry data and remote monitoring. Moreover, parameters can be adjusted during flight and flight data of flight control can be transmitted back, but large-capacity data cannot be transmitted.

The second stage: image transmission, which is used to meet the needs of high-resolution image/video real-time transmission for aerial photography, maintenance, measurement, mapping and monitoring. The UAV needs to be equipped with a wireless communication module that can realize wireless image transmission. At this stage, the image transmission mainly adopts two technologies: WiFi image transmission and COFDM radio image transmission. WiFi image transmission has the characteristics of low cost and small size, and it is quickly popularized in consumer drones. However, WiFi technology is designed for indoor static close range, and its transmission distance is only a few hundred meters, so it cannot be transmitted over a long distance. And the mechanism of WiFi carrier sense determines that it cannot be used reliably in multi-unit networks. COFDM radio station follows DVB broadcasting technology, which has high spectrum efficiency and long transmission distance, and can be applied to industrial UAVs with long-distance transmission. However, COFDM radio station generally adopts one-way broadcast transmission, which can not be used in networking, and the cost is very high. At present, it is gradually replaced by LTE image transmission with networking capability.

The third stage: digital and graphic transmission, multi-unit network. Traditional data transmission and image transmission all adopt independent modules, which occupy a large volume and consume a large amount of power. The new data link graph integrates data transmission, wide and narrow bands share wireless links, and the uplink and downlink are transmitted in both directions, which improves the efficiency of spectrum use. Single module supports serial port, network port, USB, HDMI and other interfaces; Serial port is used for data transmission, and network port, USB port and HDMI port are used for image transmission. With the rapid popularization of power line inspection, highway inspection, border inspection, surveying and mapping, fire prevention and other industries, the single-control single-machine mode can no longer meet the requirements. On the basis of two-way networking, multi-machine and multi-station networking is required.

Based on the application requirements of the above UAV scenes, Chenxin Technology launched the CX6672 graph data transmission module. Based on the SDR chip platform of Chenxin Technology, this module supports broadband data transmission of point-to-point and point-to-multipoint star networking. This module is based on LTE wireless communication standard and adopts.OFDM(orthogonal frequency division multiplexing) andMIMO(Multi-Input & Multi-Output,) and so on.technologyDifferent modulation and coding methods can be applied to adapt to different channel changes and obtain the maximum transmission efficiency.

Typical application scheme: high-speed functional automatic inspection system

A number of ground base stations are deployed along the expressway, and each ground base station is connected with the monitoring center through optical fibers. When the UAV patrols along the expressway and reaches the wireless coverage area of a base station, the patrol video image is transmitted back to the command center through the base station; When the UAV flies to the coverage area of other base stations, it automatically switches transmission paths seamlessly, and data is not lost during the switching process.
