There is another wave of price increases in the new energy market. Why are electric cars so expensive?

With the development of modern science and technology, electric vehicles have gradually appeared in public view and won favor. People are full of interest in this new energy vehicle, but they have no choice but to stop at its price. Will electric cars never be cheaper than fuel cars? First of all, electric vehicles are more expensive than fuel vehicles in manufacturing costs. The cost alone is almost twice that of a gasoline car, so the price goes without saying. For example, the well-known Toyota Corolla model, the traditional fuel version100000 can start in the early days, but the hybrid version will be more than150000 even after subsidies. If it is a pure electric car, the price will be higher. You must have a lot of questions, so keep reading with Bian Xiao.

Nowadays, many electric vehicles use the same gasoline vehicle shell, so Tsinghua University has a paper entitled "Study on Energy Consumption, Carbon Emission and Cost-Benefit of Electric Vehicles in Life Cycle". It says that the electric car is made from the traditional gasoline car by replacing the gasoline power system and adding the electric power system.

Bian Xiao once read an article saying that if it is a domestic car with a price of100000 yuan, including R&D, assembly and materials, the total cost is only about 50% of the selling price. After removing the components of gasoline power system such as engine and gearbox, the cost of a car shell is only about 30% of the price of the whole car. Then it is obvious that the shell cost of an electric vehicle with a class of100000 is about 2 1 000.

In addition to the cost of the car shell and electric car, we should also add the power system mentioned just now, that is, battery, motor and electronic control. Probably similar to the four-wheel drive I played when I was a child, there are batteries, motors, good motors, bad motors, and finally a switch, just like the current electric car, which can convert electric energy into kinetic energy of the vehicle.

Let's talk about batteries first. At present, the batteries used in electric vehicles are basically ternary lithium batteries. Among the first eight batches of 296 electric vehicles announced by the Ministry of Industry and Information Technology, there are ***22 1 vehicle using ternary lithium, which is too much. Then, according to the data of UBS Group AG, an international investment analysis organization, the current domestic price of ternary lithium batteries is RMB 0/042 per kWh. Take BYD Yuan EV, which ranked first in electric vehicle sales in 20 18, as an example. 42-degree battery 44000.

Then there is the cost of motor and electronic control. The battery capacity of the electric vehicle itself is not very large, so the motor power will not be too large, otherwise the battery may be damaged if the power consumption is too fast. Batteries are so expensive, we must protect them, don't you think? Then the motor of 65438+ 10,000 yuan electric vehicle is generally a single motor, and its power is about 100 kW, which is similar to the maximum power of ordinary family car engines. The power is lower than 80 kW, and the larger ones are 1 15 kW. Therefore, according to the comparative study of battery China network and mainstream power batteries at home and abroad, a set of motor with power of 100 kW and supporting electrical system needs 20,000 yuan.

Now let's calculate the total cost of making a car. Shell 2 10000, battery 44000, motor and electric control 20000. 100000 electric vehicles cost 85000, almost twice as much as fuel vehicles. In this way, the high price still makes sense.

To tell the truth, the cost of electric vehicles is still relatively high, mainly relying on state subsidies and policy benefits. For those of us who buy cars, it is a good choice to buy electric cars now, which is energy-saving, environmentally friendly, economical and practical, and also eliminates the trouble of limiting the number. In addition, the car you bought with the extra money is very expensive to build. Think about it, this is profit. what do you think?
