With the continuous development of the automobile energy revolution, now the vehicle types have been very popular. In addition to the support and encouragement of national policies, the pure electric vehicle type does have many advantages, such as energy conservation and environmental protection, and low vehicle cost, so it is gradually accepted by more and more consumers. In recent years, the popularity of domestic small SUV market has not been reduced, and it has become an indisputable place for many automobile enterprises. In this market segment, in addition to the traditional fuel models, the pure electric vehicle model also began to make sustained efforts, especially the independent brand vehicle companies, have launched their own new products. The four products recommended this time are all self owned brand models, with a endurance mileage of more than 300km, which can basically meet the daily demand of urban transportation. In terms of the price, considering the overall advantages, compared with the fuel version of the same level models, there is not much fluctuation, so this is undoubtedly a comfort for those consumers who are "forced" to choose pure electric models because there is no indicator. In terms of appearance, the overall design of new energy e-pro has a high similarity with cash, only some adjustments have been made in terms of details. "One piece smart front face" is simple in shape, while the wave pattern is very good to enhance the sense of delicacy. The tail lamp is treated with fumigation, and the lamp groups on both sides are integrated with the black decorative plate in the middle to create a through type shape. Ruihu e, ezs and Yuanxin energy are all typical "oil to electricity" models. Therefore, in terms of appearance design, the three new models basically continue the shape of their respective fuel version models, only for details, they are modified to emphasize their new energy model identity. The front grille of Ruihu e adopts a closed design, and two through mouldings on the front face further stretch the visual width. The rear of the car has a strong sense of strength. The "C" shaped tail light is connected with the chrome trim strip, which is quite delicate. Marquis ezs also continues the design language of its gasoline version. The main highlight is that it provides three body colors, namely speed red, snow white and pure electric Copenhagen blue. The saturation of light blue is low, the visual effect is fresh and elegant, which matches the identity of pure electric vehicle. Yuan ev535 is consistent with yuan ev360 in modeling outline, and adopts the BYD family style "dragon face" design language. The two-color car body and the suspended roof create a very flexible fashion atmosphere, which is highly recognizable. ??? in terms of external configuration, since the four models are all entry-level small SUVs, the gap between them is not large, and the overall performance is standard. The panoramic sunroof of Ruihu e can't be opened, which is slightly inferior to that of the other three models. Changan new energy e-pro does not support one button window lifting, so it naturally has no window anti pinch function. In this respect, Ruihu e performs best, and all windows of the car support one button lifting. In the lighting part, except for the halogen headlights used by Changan new energy e-pro, other models are led light sources, among which the matrix arrangement design is also used by Yuanxin energy. Appearance summary: in addition to Changan new energy e-pro, the other three models are all "oil to electricity". Therefore, objectively speaking, there are not many bright spots to be found in the appearance. They basically continue the design language of their gasoline models, but adjust the details. In terms of configuration, the performance of the four models is still excellent, which can basically meet the daily use. In terms of interior decoration, Changan new energy e-pro adopts the latest family style design style, the center console is generally inclined to the driver's side, and the combination of full LCD Meter and large size center control screen creates a strong sense of technology. The interior of Ruihu e adopts the design of fuel version of Ruihu 5x, with a large number of square elements and strong visual effect. Mingjue ezs interior also continues the design language of its gasoline version, with a very good material. The upper layer of the center console is covered by soft material with plastic lining technology. Although the other parts are only hard plastic, the surface texture is very fine and the quality sense is excellent. Compared with the ev360 model, BYD ev535 has made adjustments in the center console, instrument panel and door panel. The brand new simple style is the same as BYD's latest family design, with fashionable personality and a sense of technology. In the multimedia part, Changan new energy e-pro is equipped with an embedded 10.25 inch central control screen and an internal call 3.0 system, which supports intelligent interconnection, dual screen linkage, voice control, online navigation and other functions. The resolution and smoothness of the screen are excellent. Ruihu e uses a 9-inch multimedia touch screen, integrates HMI 3.0 intelligent interactive system, and supports a variety of third-party app software, such as Gaud navigation, KuWo sound source, companion listening and other applications. Mingjue ezs is equipped with zebra intelligent travel system 2.0, screen size of 8 inches, and built-in powervr dual core GPU graphics and image processor. The system interface is colorful, smooth and smooth, in addition, it supports the functions of mobile phone interconnection and voice control. BYD ev535 is equipped with dilink 10.1-inch 8-core adaptive rotary suspension display, which integrates voice recognition, intelligent voice reminder, Bluetooth Handsfree call, Bluetooth mobile music, vehicle digital TV and other functions, and has a complete ecological chain. In terms of internal configuration, Ruihu E and mingjue ezs are relatively better. In addition to the LCD Meter, leather multi-functional steering wheel and faux leather seats, they are also equipped with the electric adjustment of the driver's seat and the front seat heating, which can be said to be a performance of over class configuration. In addition, Ruihu e is equipped with automatic air conditioner, air outlet of rear air conditioner and PM2.5 filtering function in the car. The highlight of Changan new energy e-pro is its 11 inch full LCD instrument, with excellent display effect. The interior configuration of new energy is characterized by a rotatable central control panel, which can be automatically adapted according to different applications. Interior summary: in terms of design, the interior styles of the four models are mainly simple and fashionable, among which Changan new energy E-Pro and Yuanxin energy adopt the minimalist style, while Ruihu E and mingjue EZS basically continue their respective family design, with a strong sense of hierarchy. In the configuration part, Ruihu E and mingjue ezs are more eye-catching, but the performance of the other two is not bad, such as multi-functional steering wheel, LCD Meter and front central armrest. Changan new energy e-pro is equipped with a driving motor with a maximum power of 120kw, a peak torque of 245n · m, a power battery capacity of 48.3kwh, and a endurance mileage of 401km under NEDC conditions. For the charging part, it only takes 30 minutes to charge from 30% to 80% in the fast charging mode, and 8.7 hours to charge from 0 to 100% in the slow charging mode, according to the official. The driving motor of Ruihu E has a maximum power of 95kw and a peak torque of 250N · M. The battery capacity is 53.6kwh, and the air-cooled temperature control system is adopted, which is provided by two suppliers of Javert power. In Ningde era, the battery energy density is 144wh / kg, while the battery energy density of Jiewei power is 160wh / kg. Although the battery energy density is different, the endurance mileage of MIIT is 401km. Mingjue ezs is equipped with EDS intelligent electric drive system, and the motor is designed with hair pin winding, which can effectively improve the working efficiency. The battery pack is a catl high energy density anti-aging lithium battery, with the energy density of 161wh / kg and the endurance mileage of MIIT of 335km, which is slightly worse than that of competitors. In terms of charging, mingjue ezs can charge 80% of the electricity in 30 minutes with fast charging, and 6.5 hours with slow charging. BYD ev535 is built based on E platform. Under the technical advantages of high integration and integration, the new car continues to use the three in one design of motor, transmission and controller. The charging part can be fully charged in 1.1 hour, while the household 220 V wall mounted charging box takes 9 hours. Among the pure electric vehicles of the same level on the market at present, BYD ev535 is one of the products with the widest application range, which can be compatible with almost all charging piles on the market, and even 500V high-voltage charging can be supported. Power summary: with the continuous development of the industry, today's pure electric power assembly has become more and more mature. In the endurance part that consumers are most concerned about, except that the famous ezs is slightly inferior, the endurance mileage of the Ministry of industry and information technology of the other three models has exceeded 400km, which is undoubtedly satisfactory. In terms of charging, the four models all support fast charging technology, with fast charging and long endurance. From the perspective of meeting the daily demand of urban step-by-step, the overall performance is excellent. For the part of riding space, thanks to the high ceiling and straight sitting posture of SUV models, the performance of these four models is pretty good. In combination with panoramic skylight, the vision is quite wide, even in the back row, it will not be depressed. Ruihu E has a wheelbase of 2630mm, so its rear leg space will be larger. From the perspective of actual performance, none of the four models encroached on the ride space due to the existence of batteries, even for the "oil to electricity" model, so it can be seen that the manufacturers have made great efforts in space design and utilization. In terms of storage, Ruihu e is the only one of the four models equipped with rear center armrest, so there are two more rear cup holders, and the through design can also be used for storage. The design of Yuanxin energy in the central armrest of the front row is very characteristic. The integrated storage tank has a very high utilization rate of space and can put down a lot of sundries. Changan new energy e-pro and mingjue ezs do not have much eye-catching part in storage, but the door panel storage tank and the front central armrest box can meet the daily storage needs. The trunk volume of the four models is roughly the same, and the second row of seats also support the proportion of tilting, which can further expand the storage space, which is very important for SUV models. Yuanxin energy adopts the side open tailgate design, and the "small schoolbag" shape of the external spare tire also liberates part of the interior space. Summary of space: the performance of the four models is basically at the same level, regardless of the riding space or storage space. In terms of size alone, Ruihu E has a small advantage in the riding space. Storage part, these four models can also be satisfactory, at least to meet the basic daily household pressure. The space in the trunk is very regular. The second row of seats support the proportion of reclining. The practicability is excellent. Safety summary: in terms of safety configuration, Ruihu E has provided a wealth of active and passive safety configuration, including front exhaust bag, front side airbag, esp body stability control system, reversing radar, 360 ° panoramic image, parallel assistance, lane departure warning and road traffic sign recognition, which can be called a super performance, and the outstanding active safety configuration is enough to let the other three models watch out And. In addition to the conventional passive security configuration, the security of ezs is mainly reflected in many invisible places. As a global model built according to European standards, it has passed a lot of safety certification, including e-maek certification of European standards, IP67 dust and water discharge index of International Electrotechnical Commission, European reach vehicle environmental protection standard and ul2580 battery safety certification of the United States. The overall performance of Changan new energy e-pro and Yuan new energy is in line. The former supports the monitoring of the blind area of reversing, while the latter provides 360 ° panoramic image. Unfortunately, in the passive safety part, the lack of side airbags in the front row is more regrettable, and the yuan new energy is slightly better, which provides the opportunity to choose. Conclusion: Although the pure electric vehicle has not been fully recognized by the market at present, objectively speaking, it does have a lot of inherent advantages, including the trouble of unrestricted number and lower cost of vehicle use.
