After several rounds of reshuffling, the domestic pure electric mini car market has become hot again in the past one or two years, of which most of the heat is brought up by Hongguang MINIEV, and 30,000-40,000 yuan can buy a fashionable scooter, catering to the needs of many young people. However, some friends feel that in the case of the generally low retention rate of electric vehicles, 30,000-40,000 yuan can choose a pure electric car with a slightly earlier age and looks more "normal", of course, although these products also have some problems, at least they will be more spacious and comfortable to open up and use. So will it actually be like this? Or at this price, no matter what pure electrical products you buy, it is a pit? Let's take a brief look at it.
The price is inflated, and the five-year retention rate of pure trams in the early days is only about 20%.
The earliest batch of pure electric vehicles in China is in the context of the country's vigorous promotion of new energy vehicles, and there are higher subsidies under the advent of the birth, the launch time of these products is mostly 2013-2016, mainly oil to electricity models, their retention rate is generally not high, five years of car age can have 20% even if it is good, so 3-40,000 yuan of budget, there are still a lot of pure electric used cars to choose, below we will pick a few to see.
BAIC BJEV EV: It is a pure electric small car based on the E series of Beijing Automobile oil to electricity, the guidance price of the early model sold to 249,800 yuan (excluding subsidies), the endurance range ranges from 160-200km, and is equipped with fast charging, 1 hour can be charged from 30% to 80%, the motor power is 53kW, the zero hundred acceleration time takes 15 seconds, and it is equipped with a ternary lithium battery. The price of the later products fell to less than 100,000 yuan, but the endurance also dropped to 150km, the motor power dropped to 45kW, there was no bright spot in the configuration, and now the second-hand car with a car age of 6 years and a mileage of about 30,000 kilometers is about 30,000 yuan.
JAC iEV5: the same is a pure electric small car with oil to electricity, the product characteristics are similar to BAIC New Energy EV, the price of the early product was sold to more than 170,000 yuan (excluding subsidies), the cruising range was 170km, using a 50kW motor, the maximum torque of 215 Nm, equipped with a ternary lithium battery, also equipped with fast charging. Used cars with a age of 7 years and a mileage of about 40,000 kilometers can be sold for about 30,000 yuan.
Roewe e50: This is a pure electric mini car launched by Roewe in the early days, the price of the early model sold to more than 230,000 yuan (excluding subsidies), the mileage is 120km, there is no fast charging function, equipped with lithium iron phosphate battery, the configuration is equipped with a central control LCD screen, the rest has no highlights. Now this car is 8 years old, and the price of 20,000 kilometers of used cars is more than 30,000 yuan.
Denza: This car is a pure electric medium-sized car jointly launched by BYD and Daimler of Germany earlier, and the price of the 2014 model was sold to nearly 400,000 yuan, which is an absolute high-end pure electric car. The range of the 2014 model is 253 km, and the mileage of the 2017 model is more than 300 km. In terms of power, the 2014 Denza model is equipped with an 86kW motor, zero hundred acceleration for more than 13 seconds, and the use of lithium iron phosphate batteries. Now the 2014 model has been 6-7 years old, the mileage is less than 70,000 kilometers of used cars, the price is in the early 40,000 yuan.
There are many bugs in the early used car electric vehicles, and the figure is cheap and easy to enter the pit
From the price point of view, although there are some policy factors in the early launch of pure electric products, their second-hand car prices are still very cheap, 3-4 million yuan has a lot of choices, so this makes some friends have the interest to buy these second-hand products, thinking that it will be better than the current new pure electric mini car. However, this is not the case in practice, mainly because there are many product defects in early pure electric vehicles, which will cause some inconvenience to daily cars.
For example, BAIC BJEV EV has problems such as inaccurate odometer, fast power loss, and serious endurance attenuation, and the nominal endurance is 150km, but it is actually only 80km. In addition, the battery management system of this product often fails, resulting in the vehicle being unable to charge normally. According to user feedback, although this car has an 8-year 150,000-kilometer battery warranty, there are some battery problems in the warranty, and the 4S store will basically only balance the battery, and the cost is about three hundred yuan at a time. Although jacques iEV5 comes with its own battery balancing system, it often fails, which means that it is still necessary to go to the 4S shop for repairs, which often affects the use of the car.
Roewe e50 second-hand car ownership is not high, but there are also some problems in the product, such as poor workmanship, car machine Caton is not smooth, lithium iron phosphate battery battery attenuation is serious, etc., 120km endurance, now may only be less than 70km can be opened, basically reduced to chicken ribs, left useless, abandoned pity, more importantly, there is no fast charging function to make the owner of the car more inconvenient.
The main problem with Denza is that the vehicle often shows a powertrain failure, which is very troublesome to repair. At the same time, Denza's car machine will often restart or black screen, and because the vehicle air conditioning control is integrated into the car machine, so the car machine problem will be unable to control the air conditioning, can only rely on the Auto key to switch the air conditioning, seriously affecting the use of the car. Later models took the air conditioning control function out of the car machine system separately, or also considered the problem of the car machine, and made up for it.
The early problems are now solved, but buying a new car also depends on the car environment
The main problems of early pure electric vehicles mainly focused on battery management, inaccurate endurance, and BUG in the car machine system. Among them, the battery management system problem is the most common, this is because the early system has limited management capabilities for each battery cell, so it is easy to cause problems such as voltage instability, inability to charge, virtual power, etc., so that the owner needs to balance the battery for a long time, which is not only time-consuming and laborious, but also very painstaking. Another point is that the early tram battery capacity is too small, the mileage is too short, and because the technology is not in place, after several years of normal use, the battery will have a serious attenuation, and the endurance will be further shortened, which is undoubtedly worse for the vehicle that does not have a long mileage itself, and the vehicle is easy to become a chicken rib.
In individual brands of pure electric models, there are also some workmanship, material problems, such as the vehicle is used for a long time, the joint, socket will appear loose, aging, rust, just like when the DCDC converter interface problem, after the interface is loose, the vehicle will appear power out of power protection, which is why we can often see the old electric vehicle anchored on the road.
In contrast, all aspects of the current pure electric car will be mature a lot, such as the battery management system is more accurate, intelligent, can more effectively prevent the battery from overcharging and overdischarge, thereby prolonging the service life of the battery, in addition, the BMS battery management system can also monitor the status of the battery, ability control, etc., more importantly, even if it is a pure electric mini car of 30,000-40,000 yuan, its BMS battery management system can also be very reliable. At the same time, the integration of the current pure electric vehicle three-electric system is also very high, which can reduce the risk of loose sockets and rust, and improve the safety of the car.
Although the mileage of the new pure electric mini car of 30,000-40,000 yuan is not particularly high, most of them are only about 200km, but because it is a new car, the endurance rate is still guaranteed, at least in the conventional car environment, it will be more normal to lose power. For young people more concerned about the car machine system, the current car machine system has made great progress, and most of them have realized the Internet of Vehicles and other functions, further improving the convenience of using the car, more importantly, these car machines are stable, the operation logic is simple, and some also have voice recognition control and other functions, with high practicality, which is also incomparable to the early products.
Of course, here is not to say that the new pure electric mini car must be better than the second-hand pure tram, after all, due to product reasons, this type of model also has no small problems, the first is that the vehicle is too small, the driving stability is general, such as the "God Car" Hongguang MINIEV, whenever the speed exceeds 60km/h, the vehicle will flutter, high-speed stability can not be compared with high-level models, only suitable for urban low-speed transportation. In addition, many of these models do not have fast charging functions, so if there is no household charging pile, buying these products will not only have mileage anxiety, long-term charging is also a kind of torture, so whether it is worth buying, but also depends on whether the owner's car environment is supported.
summary:
From the price point of view, 3-40,000 can indeed buy a lot of early pure electric products, but these models have some hard injuries in terms of mileage, BMS battery management, etc., too many small problems, and with the increase of mileage and time, these problems will be more prominent, no doubt will cause many inconveniences to daily cars, so it is not recommended to buy. In contrast, the quality of the new pure electric mini car product at the same price point is much more stable, at least for 3-5 years without worry. Of course, endurance attenuation, no fast charging, and poor high-speed stability are also unavoidable for such products, so if these can be overcome, I think the new pure electric mini car of 30,000-40,000 will be more worth buying.
