Oil prices continue to be high, causing more and more users to consider purchasing an electric car. After all, daily expenses are much cheaper than fuel vehicles. However, many users also have doubts about electric vehicles, including many aspects such as battery life, vehicle reliability, safety, and charging convenience. They are very eager to understand the real feelings of using electric vehicles in daily life.
Therefore, led by Pinhui Automobile and Automobile Information Network, it has jointly created and participated in the creation of the "new energy vehicle series evaluation of urban car use scenarios under non-special working conditions" to test the vehicle's performance and strength in a suitable scenario for daily car use. Testing was conducted from four major items, including ten minor items, covering various common road conditions such as highways, cities, congestion, as well as car use and charging scenarios. All vehicles participating in the evaluation are quasi-new cars, and they are fully experienced in an open and transparent test environment.
The purpose of this review is "We will test what users pay most attention to." The purpose of evaluating these popular electric cars in real car use scenarios in urban road conditions instead of conducting extreme tests in high temperature and high cold environments is also highly consistent with consumers' car purchase needs and car use needs. Therefore, it is more reference value and guiding for consumers, and can truly understand the true strength of these electric cars. At the same time, for the industry and car companies, a fair, just and open test can also promote the healthy development of the industry.
Select the hot-selling models on the market
as the first season of the new energy series test event "Who is the King", and the evaluation of "Who is the King of Little Cars" selected the five most popular and most concerned mini cars on the market at present - Wuling Hongguang MINIEV 2022 Macaron Zhenxing Edition 170km version, Changan Lumin 2022 210km sweet model, Chery QQ Ice Cream Sundae 170km version, Chery Little Ant 2022 sweet powder half sugar version 301km version and Leap Run T03 2022 Star Diamond Edition 403km version. In addition, most of the five models are quasi-new cars with mileage of less than 1,500 kilometers. This ensures that the horizontal evaluation data is fair, and the evaluation results can be helpful to users when purchasing a car.
At the same time, our event publicly invited more than 20 professional media including Phoenix Auto, Baidu Youjia, Youhua, 30 Seconds Daoche, Wu Pei Channel, Nice Good Car, Che Degang, Che Yitiao, Dianju, Daoge Talk, Electric Vehicle Commune, Aika Auto, China Economic Net, China Economic Times, and Pinhui Automobile's Automobile's Automobile, Motor Video, E-Chehui, Dachehui, etc. to jointly create and participate in the evaluation to ensure the fairness and authenticity of the test.
Evaluation items close to daily car use scenarios
For most users who potentially buy electric cars, the most concerned about are undoubtedly the dimensions such as charging, battery life, and intelligence level. The air quality in the car, air conditioning and cooling capacity, acceleration braking level and even vehicle handling cannot be ignored, and even micro cars cannot be cheap and not good-quality.
For this reason, this review covers three categories: comfort experience, performance experience and car use scenario experience. Among them, the comfort experience includes three evaluation items: "test for excessive harm such as formaldehyde", "UV isolation test in urban summer sun-dried environment", and "air conditioning and refrigeration test". In the performance experience, four items, including "urban section acceleration test", "daily commuter battery life test", "charging test in daily and emergency scenarios" and "safety performance" are set to test the various performances of new energy micro-vehicles on urban roads.
In addition to the above conventional items, three car use scenario experience evaluation items, including "space test in travel scenarios", "car use cost test", and "intelligent testing" have been added in this evaluation to further answer users' various questions about the use of micro cars. In general, our evaluation is conducted in a more suitable scenario for users to use the car, providing users with more reference value for their car purchases, without challenging the limits or evaluating vehicles under special working conditions. Specifically in terms of evaluation methods, we have also adopted a more scientific and intuitive approach.
For example, when testing the air quality in the car, we will close the windows of the whole car, so that the vehicle will expose the sun for two hours after two hours, use professional formaldehyde testing instruments to collect formaldehyde volatile gases in the center of the car, detect the volatile formaldehyde concentration, and evaluate the formaldehyde content in the car by detecting the numerical value. The air conditioner refrigeration effect is also very important for a car, especially a micro electric vehicle. For this reason, we have asked the vehicle to turn on the air conditioner for two hours after the sun is exposed to the scorching sun, and the maximum air volume is half an hour to see which car has the lowest temperature inside, so as to evaluate its air conditioner refrigeration effect.
In the four tests of performance experience, the "Simulated Urban Road Section Acceleration Test" is the time it takes for a vehicle to accelerate from 0 to 60km/h in ECO or standard driving mode. For a small car, the shorter the acceleration time, the better the vehicle's power performance. At the same time, not only should we test the no-load, we also added the acceleration test under the full load of four people. In addition, good acceleration is not enough, and it can be braked when encountering an emergency. Therefore, we also tested the vehicle from emergency braking at 60km/h to parking at an emergency speed, to see who has the shorter brake distance.
In addition, handling is also an important indicator to evaluate whether a car is good or bad, even a microcar is no exception. To this end, we also set up a pile-circling link. The driver drives the test vehicle around the pile separately, and evaluates the vehicle's handling through the driver's subjective feelings and the vehicle's driving status.
For the core point of electric vehicles, we choose the daily commuting endurance and charging, which simulates commuting routes for commuting on urban roads, and normally turn on the air conditioner and set off with full power, arrive at the end to charge, and finally calculate the charging time, power consumption and other data. In addition, we also test the vehicle loading capacity and intelligence level one by one to test the convenience of each car.
Scoring standards for pursuing fairness and justice
After conducting a series of professional evaluations, the subsequent scoring and evaluation standards are also very important. For this reason, we have formulated a set of scoring standards that are not only suitable for small cars. In the future, this set of standards can also be used when comparing higher-level models with horizontal evaluation.
First of all, in terms of scoring, we use the percentage system commonly used in general exams, which looks more intuitive. Since it is a horizontal evaluation, most of the projects we tested will have data, so there will be a ranking.
This time, a total of ten major projects were tested, so the proportion of each project is 10%. We will give a ranking score for the corresponding sub-projects. Taking the air quality in the car as an example, among the five cars, the one with the best air quality in the car, that is, the first place will get 100 points, the second place will get 80 points, and the second place will get 20 points, and so on, the last place will get 20 points. If the relevant values do not meet the national standards, then this item will record 0 points.
In addition, in addition to conducting data testing, we also introduced some important configuration comparisons into horizontal evaluations, such as smart car system, reversing image, L2-level assisted driving, voice control, mobile app remote control, etc. When the vehicle has relevant configurations, it will also obtain relative scores to evaluate a car more comprehensively.
In addition to the single score, the results of this evaluation also introduce "quality price ratio" data, which is derived by dividing the total score of the test vehicle by the sales price of the test vehicle. If the vehicle's evaluation score is high and the selling price is low, then its price ratio score is high, which reflects that the model is more valuable.
After three days of systematic review and reasonable calculations, the results of the new energy series test "Who is the King" season 1 "Who is the King of Little Cars" have been released. In the end, two models from Chery New Energy Vehicles - Xiao Ant and QQ Ice Cream, won the first place in total score and the first place in price ratio respectively.
In general, this new energy vehicle series review strives to be fair and just, and it is also more in line with the actual car use scenarios of users. It has greater reference significance for users to buy car tools, and is the goal we strive to achieve! All work is also carried out from this original intention. We will conduct horizontal reviews of more levels of models in the future. Stay tuned!
