There has never been a clear policy for battery scrapping, but with the surge in the number of electric vehicles, dismantling of power batteries must be considered. It is necessary to establish a complete system to avoid overflow of power batteries from polluting the environment.
The most valuable component of an electric vehicle must be the battery pack. Taking a model of a certain brand with a price of 200,000 yuan and a battery capacity of 70kWh, the current price of a 1kWh power battery is around 1,000 yuan, and the cost of the entire battery pack is around 70,000-80,000 yuan.
The cost of the battery pack accounts for 35% of the entire vehicle price.
All batteries will decay, and any product is no exception. According to the standard analysis, if the capacity is lower than 80% of the rated capacity, it can be scrapped, and the manufacturer is responsible for the warranty.
Whether you replace it yourself or the manufacturer is responsible for it, there should be a recycling path for the replaced battery pack that does not reach the capacity.
There are currently some qualified outlets that can recycle retired batteries. The recycling price standard is based on the residual value analysis. For example, if the remaining battery pack power is 50 kilowatt-hours, then the maximum recycling rate per kilowatt hour is 400 yuan. In other words, a battery pack that used to be 70kWh, The final recycling price is up to 20,000 yuan.
Remember, 400 yuan is the maximum recycling price, and generally it will be lower than this price.
There are two ways to deal with retired batteries. One is to dismantle and reorganize them and continue to use them in areas where the battery energy is not high and in products to squeeze out the maximum value. The other is to extract the precious metals from the used batteries. .
Generally speaking, as long as power batteries are not overused, they will have a relatively stable life. It is rare for the actual capacity to be less than 80%, but this does not mean that it will not happen. A complete battery recycling system is currently being established to Large-scale elimination will occur after 5 or 8 years.
After all, as of June today, there have been 10 million electric cars . This year’s sales will reach 6 million. In the next 5-8 years, the number of electric cars will exceed 40 million. Such a huge sales volume A reasonable retired battery disposal system must be established.
But for users, once the power battery is replaced, it is actually a dilemma.
On the one hand, the power battery capacity is less than 80%, which means that an electric vehicle that was previously calibrated at 400km can only run 280km. In fact, it can only run about 200km. The performance is seriously attenuated, and the cost of replacing a new battery pack is very high.
On the other hand, if you choose not to replace it, the electric vehicle will basically be in a "fault state" and cannot be used normally and efficiently.
The cost of replacing a new battery pack is too high, and the residual value of selling used battery packs is very low. This involves a question of "whether it is really economical." The theoretical life of an electric vehicle is very long, but this entirely depends on the life of the battery pack.
If used in an unreasonable manner, the problem of rapid battery attenuation may manifest itself at 100,000 kilometers. Taking a 70kwh battery pack as an example, its cost is 70,000 to 80,000. If the capacity drops to 80% at 150,000 to 200,000 kilometers, Then it must be replaced, and the cost of the battery pack is about 60,000 yuan.
Since the daily charging of electric vehicles is not entirely done at home charging piles, the high cost of commercial charging piles cannot be ignored.
The cost of electric vehicles is mainly concentrated on the three-electric system. The stability of the motor and the attenuation of the battery must be considered. In fact, the cost of replacing a high-speed motor is also very high. The reason for the high cost of battery and motor maintenance and replacement is the industry The chain is immature and the supply system is imperfect, resulting in extremely high costs.
The electric vehicle market, which is growing by millions every year, must make us rethink whether the daily economy and high maintenance costs of electric vehicles are really suitable for everyone.
