I've been driving an electric car for six years and sometimes want to complain. Old drivers often say this. What is the overall performance of a pure electric vehicle? As long as you drive it at high speed and go home for the Spring Festival, the advantages and disadvantages of pure electric vehicles will soon appear. Its advantages are obvious, but there are still three major pain points, each of which is a chest hit, and finally share five daily driving pure electric vehicle precautions.
Pain point one, high speed is the "demon mirror" First of all, the highway speed is generally above 100, pure electric vehicles are driven by motors, driven by a fixed speed ratio, the faster the speed, the greater the power consumption, the greater the power consumption, and the high-speed power consumption is almost twice that of the city bus. Secondly, pure electric vehicles HVAC generally use ptc heating, which consumes a lot of electricity. According to past experience, the average operation of HVAC is 1 hour, and the power consumption is about 1.5-3 degrees. Of course, the specific amount of electricity consumption is related to many factors such as the electricity and environment of the model air conditioner, which is the opposite of the HVAC for fuel vehicles. The fuel vehicle makes full use of the heat of the engine, and the fuel consumption is very small. Finally, the mileage of pure electric vehicles is greatly affected by low temperatures, during the Spring Festival, Jinan to Hebei Chengde to the north, the temperature also gradually dropped from about 5 degrees to minus 13 degrees, before departure full charging mileage of more than 500 kilometers, Tianjin the whole 320 kilometers, then the rest of the routes
Pain point two, charging difficulties, slow charging installation of charging piles are very strict requirements for residential properties. Must be an ownership parking lot. For safety reasons, the cable should not be too far from the main power supply. For short parking lots, the property requires the consent of the owner, and the relevant safety responsibilities are borne by the owner. Therefore, many property owners do not agree with lessors installing charging piles. That said, personal charging piles are now only suitable for people who have ownership of parking lots. If you do not have your own charging pile, you can only go outside to share the charging pile to charge. At present, the number of charging piles is increasing, but mainly concentrated in bustling areas, shopping malls, office buildings, around the main campus, there are many people charging in these areas, often only need to run and charge in places above the third ring, which is a waste of time and waste of energy, especially during the Spring Festival and National Day, many pure electric vehicles flock to the highway, but the number of charging piles in the current service area is not enough.
In the past, during the National Day, the charging piles in the service area lined up in a long line, becoming a "slug-like" for grabbing charging piles, which were incompatible and eliminated the fault bracket. Some service areas only have more than 10 charging piles, and there are often more than 10 owners waiting for charging, often dozens. If there are only 10 charging piles, there are 10 people waiting, but even if you use a charging pile every 40 minutes, you need to wait for at least one person, compared to about 5 minutes for a fuel car to fill a tank of fuel. After three or three years of pain points, no one wants to take over pure electric vehicles Currently lack a complete second-hand evaluation system, and the battery guarantee policy is worrying. A manufacturer of pure electric vehicles with various guarantee conditions. For example, for a person who repairs a chassis with an accident car, only the first owner can enjoy services such as a free warranty. In addition, due to the concern about the fast battery life and high battery replacement costs, the warranty rate of second-hand pure electric vehicles is too low, and the warranty rate of the first year is OK, but after two or three years, it plummets, and the gap with the warranty rate of fuel vehicles is too large.
Although there are many pain points, the advantages are also obvious In fact, the original intention of buying pure electric vehicles is very simple, and charging is cheap. As far as I am concerned, the average electricity consumption of a hundred kilometers is 15 degrees, and the charging pile of my own home is less than 6 yuan at a time, less than 9 yuan for a hundred kilometers, a dime for one kilometer, and 5-9 hair for a kilometer for fuel vehicles. There is no doubt that the mobility cost of pure electric vehicles is very low. Secondly, the power performance is excellent, the motor is driven, and the torque is completely incomparable with the same level of fuel vehicles. 200,000 pure electric vehicles, whose power performance completely crushed more than 500,000 BMW, it is estimated that future off-road vehicles will not have any fuel vehicles. Finally, enjoying the green license plate, not just the license plate, is the gospel of many second-line car owners, full of technology, automatic assisted driving is also loved by many car owners, many car owners are worried about how to choose fuel vehicles and pure electric vehicles. We all know that its advantages are obvious, but the three pain points are the weaknesses, depending on their own car environment and car needs. Driving a pure electric car 5 points need special attention
1. The planned charging time is during the Spring Festival in winter, and the low temperature weather has a greater impact on the cruising range, and it is necessary to make a power replenishment plan in advance. For example, the endurance distance of the vehicle nedc is 500 kilometers, and the actual driving distance is best calculated by about 40% off. In fact, only 300 km can be planned. In this case, the remaining driving distance of 80 kilometers must be replenished in advance. That is to say, if the official endurance distance reaches 500 kilometers, and the actual driving distance reaches about 220 kilometers, it needs to be charged. You can also go to the next service area in case the service area column is too long.
2, rest days to avoid charging in the service area rest days, many people in the service area queue charging, then do not need to go to the service area to charge. Find the nearest charging pile from the charging APP, and charge faster when you get off the toll booth and go to the street. 3, low temperature high-speed HVAC, which is the "enemy" of pure electric vehicles on the highway, when the endurance distance is not enough, please reduce the speed, keep a uniform speed of about 80-90, try to avoid sudden acceleration, and close the electrical equipment that can close HVAC, music, navigation, etc. In general, the driving computer indicates that the remaining range is 0. At this time, it is possible to travel about 15-30 kilometers. For details, please refer to the model and the environment of the car.
4, driving precautions Pure electric vehicle motors are more delicate than fuel vehicles. When starting, steep slopes, and heavy loads, try to avoid pressing on the electric door. Instantaneous large current is easy to produce lead sulfate crystals, long-term serious situation will directly affect the physical properties of the battery plate. Again, try to avoid long power outages. When parked in a power outage, sulfate and lead sulfate crystals are easily attached to the plates, which may affect charging and discharging performance. If you do not use the car for a long time, please fully charge the car and then stop. 5, winter, low temperature environment charging as far as possible do not use fast charging, especially below minus 15 degrees, the use of rapid charging, lithium precipitates in the power battery, on the other hand, metal lithium is easy to precipitate. The damage to the battery in this situation is irreversible, and pure electric vehicles enable battery protection and battery preheating, and the charging efficiency is also reduced. Charging in this way for a long time will affect the life of the battery, but also reduce the safety of the battery, so please try to charge slowly.
In short, if you want to get a pure electric car, you can't have endurance uneasiness. If you already have a fuel car at home and get a second pure tram, that's the perfect combination. If you want to save money instead of daily private cars, you can get pure electric vehicles within 30,000 or 50,000, don't care about the retention rate, and sell second-hand cars after a few years don't care about how much money you lose. If the price of the tram exceeds 100,000, in terms of economic costs, the battery replacement cost of the premium second-hand residual value of the new car is much higher than the maintenance cost of the saved gasoline cost. In fact, fuel saving does not "save money", does not consider the cost of the car, after driving a pure electric vehicle, I really do not want to drive a fuel car.
