Abstract: The new national standard 12.13.2 clearly stipulates that "pure electric vehicles and plug-in hybrid electric vehicles should be able to emit appropriate warning sounds to people outside the vehicle when the vehicle starts and the speed is below 20km/h." When a leakage occurs in the vehicle, a clear signal device should be used to alert the driver, and the vehicle should have the function of cutting off the power circuit to avoid secondary traffic accidents. From Kunming to Shangri La, there are exactly two 300 kilometers. For most fuel vehicles, the significance of one 300 kilometer is only half a tank of fuel or a few tens of kilograms of exhaust emissions; For the new Yidong EV300, it takes a cup of coffee time to expand, in exchange for two 300KM+with zero pollution and zero emissions, and the blue sky of Shangri La.

With the increasing prominence of global environmental issues and the acceleration of urbanization, pure electric new energy vehicles are also becoming increasingly popular. Whenever pure electric EV vehicles are introduced, they will quickly become "internet celebrities" in the automotive industry. On October 19th, at the launch ceremony of Changan Automobile's "Shangri La Plan", Changan's new Yidong EV300/Yidong PHEV was officially launched.
The new car has significantly improved in terms of range, battery temperature control management, and charging time. The comprehensive driving range can reach 300km, and the constant speed driving range of 60km/h can reach 360km. After the comprehensive upgrade, how does the quality performance of Changan New Yidong EV300 perform? Red Dot in the car market experienced the Changan New Yidong EV300 for the first time and will provide readers with a comprehensive interpretation from three aspects: continuity, quality, and efficiency.

The extraordinary significance of the extended 300 kilometer range
When it comes to pure electric new energy vehicles, it is inevitable to first mention the issue of endurance. Compared to the previous generation's 200 kilometer range, the additional 100 kilometer range is a "qualitative leap" for the Changan New Yidong EV300: the vehicle's power has increased to 44.97 kWh, which has reached the peak of the current Chinese brand's new energy vehicle range level.
For household consumers, a range of 300 kilometers can broaden the radius of urban travel and enrich travel trajectories. For small and long-distance intercity travel, the range has always been a constraint on people's travel. The new Yidong EV300 with a 300 kilometer ultra long range not only extends the straight-line distance of travel, but also expands the commuting radius.
Here are two examples: taking Shenzhen, the test drive location, as the center and a radius of 150 kilometers for the turnaround calculation, the Changan New Yidong EV300, with a total length of 122.8 kilometers on the Guangzhou Shenzhen Expressway and a longer range, can easily travel between Guangzhou and Shenzhen. The excess power can also meet the traffic congestion and entertainment, as well as air conditioning needs on the road.
If calculated based on straight-line distance, the ultra long range of 300 kilometers will also expand the possibilities of pure electric travel. From Beijing to Qinhuangdao, Chongqing to Chengdu, Shanghai to Nanjing, Wuhan to Changsha, similar intercity travel can now be achieved with the Changan New Yidong EV300, which used to have a range of 200 kilometers that pure electric vehicles could not complete. At a constant speed of 60km/h, the longest range can reach 360km, which is comparable to the mainstream level in the market and has a significant advantage over many pure electric cars in terms of range.

The time for a cup of coffee sets off again
For a pure electric new energy vehicle, charging time is also a core experience. It is important to have a fast charging machine installed, which can break through the breakpoint of single battery range and seamlessly connect "range+uninterrupted driving". The ideal way to use pure electric vehicles in the future is, of course, to reach full charge again after just a few minutes of entering a gas station like a gasoline car.
Under current charging technology, the Changan New Yidong EV300 has achieved the best fast charging technology in its class: the charger has been upgraded from 3.3 kW to 6.6 kW, and the charging time has been reduced by half compared to before. Fast charging takes 30 minutes, which is equivalent to drinking a cup of coffee, and the Changan New Yidong EV300 can be fully revived and set off again. I believe that with the gradual promotion of the "Shangri La Plan" by Changan Automobile, the fast charging time will gradually be reduced to a few minutes, and it is not impossible for it to refuel faster than gasoline cars in the future.

Quality · Precision and Quality Control
It's not that battery life is all about pure electric new energy vehicles, just like a mobile phone doesn't just care about standby time. With the popularity of new energy vehicles, consumers are increasingly concerned about the driving experience and cost of using the Changan New Yidong EV300.
Experience the Changan New Eado EV300 in Dameisha, Shenzhen, where the sense of fashion complements the city's tone. The overall shape of the front grille adopts a wide body design, supported by two horizontally extending electroplated strips, making the front of the car look wider; The color scheme adopts a blend of "translucent black" and "gemstone blue", which is both technological and dreamy.
The overall interior is black, adorned with Maya silver and blue decorative rings and stitching, exuding a strong sense of sportiness amidst a calm and elegant atmosphere; At the same time, it is consistent with the grille color scheme, strengthening the identity of a pure electric vehicle.
In terms of power, the Changan New Yidong EV300 is equipped with a liquid cooled permanent magnet synchronous motor and a high-energy density ternary lithium electronic power battery, with a motor power of 90kW (122Ps) and a maximum torque of 280N · m. For a pure electric vehicle, the acceleration sensation of the new Yidong EV300 is also very obvious. It can quickly increase the speed to 80km/h without the sound of the engine, and the "throttle" pedal response is also very timely, which can be described as having abundant power.
In addition to linear output, quietness is an inherent advantage of pure electric vehicles in improving driving experience. It is precisely because it is too quiet that, in line with the principle of pedestrian safety protection, the AVAS electric vehicle low-speed prompt sound system will automatically emit a "buzzing" sound when driving at low speeds, reminding pedestrians to pay attention to the vehicle, which is very user-friendly.
In terms of kinetic energy recovery, the upgraded new Yidong EV300 has a more natural recovery force, and the drag feeling during coasting is only slightly greater than that of ordinary cars with gears. When encountering long downhill slopes, it can also have engine braking similar to gasoline cars, reducing the burden of braking.
Safety is the most essential element of batteries. The new Yidong EV300 has added a battery metal protection structure that can effectively protect the battery, reduce accidental damage, and increase its service life. In addition, in order to solve the charging and discharging problems in low-temperature environments during winter, the new car has also added low-temperature heating function to ensure its charging and discharging performance under the extreme conditions of -20 ° C-60 ° C.

The electricity cost per kilometer is only 0.078 yuan
Changan Automobile's "Shangri La Plan" hopes that future pure electric vehicles can bring back a quiet oasis in a crowded city, and of course, it also hopes to have a new definition in terms of vehicle cost. The new Yidong EV300 has indeed achieved it - the electricity cost per kilometer is 0.078 yuan.
At the end of the test drive experience, Red Dot in the car market will calculate the economic cost comparison between a gasoline car and the new Yidong EV300: taking the mainstream 1.6-1.8L displacement models of ordinary family sedans as an example, the fuel cost per 100 kilometers for a gasoline car is 8L/100km * 6 yuan/L=48 yuan.
The new Yidong EV300 has a total battery capacity of 44.97 kWh and a maximum range of 360 km. If calculated based on the market electricity cost of 0.5 yuan/kW · h, the electricity cost per 100 km is only 7.8 yuan. Adding charging service fees and other expenses, the cost of using pure electric vehicles is less than 1/5 of that of fuel vehicles. If the vehicle's mileage reaches 15000 km, it can save 10000 yuan, which means that the more mileage the vehicle travels, the more cost-effective it is. Compared to fuel vehicles, it is not only environmentally friendly but also more cost-effective.
In addition, daily maintenance costs are lower compared to traditional gasoline vehicles. Without an oil filter, a single maintenance can save about 300 yuan, which can save car owners expenses in all aspects.

Test Drive Notes: When test driving the new Yidong EV300, a great pure electric vehicle, I think we should call for something - a 300 kilometer long range, a cup of coffee charging wait, a 7-cent 1 kilometer driving cost, every highlight of Changan's new Yidong EV300 is striving to depict a new blueprint for future driving life for the community of shared future for mankind. Whether it is the holy Shangri La or the snow capped pearl Qinghai Lake, for Changan Automobile, in the context of leading the new energy vehicle strategy, the upgraded launch of the new Yidong EV300 product is one step closer to the vision of creating countless "Shangri La".
