With the deepening of the concept of environmental protection and the continuous progress of new energy vehicle technology, electric vehicles have gradually become a popular choice for consumers to buy cars. However, the cost of battery replacement for electric vehicles has always been a big concern in the minds of consumers. Taking an electric car of about 200,000 yuan as an example, the cost of replacing the battery is about 50,000 to 100,000 yuan, which makes many people hesitate to buy it.
According to the data released by the China Insurance Research Institute in November 2022, the zero-integer ratio coefficient of the power battery pack of most models is between 30% and 50%. Taking the Xpeng P3 and Xpeng P7 as examples, their battery pack zero-to-whole ratios are 4584% and 3679%, which means that the battery pack accounts for a considerable part of the whole vehicle. In the actual car purchase process, the battery pack ** given by the 4S store is also similar to these data, such as the ** of a certain battery pack of BYD is 80,000 to 8Between 50,000.
Why is battery replacement so expensive? The reason behind this is mainly that the cost of the battery itself is not low. Taking CATL as an example, its power battery shipments in 2021 will be 116700 million watt-hours, sales revenue reached 914900 million yuan. Through simple calculation, we can conclude that the unit price of the power battery is about 784 yuan kWh. And in 2020, this ** is as high as 887 yuan kWh. Considering that the CATL battery used by the Xpeng P5 has a capacity of 66With 2 kWh, the purchase cost of batteries alone is more than 50,000. Coupled with the operating costs and profits of manufacturers and 4S stores, the final ** is naturally expensive.
For electric vehicles for home use, we don't have to worry too much about the battery. Although the power battery will have a certain attenuation in daily use, its decay rate is not as obvious as that of a mobile phone battery. Studies have shown that the capacity decay of electric vehicle batteries is only 14 after 1200 charge-discharge cycles3%。The actual survey also shows that after six years of driving, the capacity decay of electric vehicles is about 12About 1%, that is, an average annual decay of about 2%. As technology continues to advance, battery attenuation is likely to be lower in new models.
Most NEV owners will consider switching to a new car within five years, so the problem of battery attenuation is not prominent. In fact, the battery capacity of five-year-old electric vehicles is still around 90%, and there is no significant decline in performance. This means that for most car owners, they will not face the problem of battery replacement when changing cars.
Many car manufacturers also provide battery warranty policies for electric vehicles, which provides a certain degree of protection for battery attenuation. This means that during the warranty period, if there is a significant decrease in battery performance, the owner can ask the manufacturer to replace or repair it free of charge.
**Ten Thousand Fans Incentive Plan Although the cost of replacing the battery of electric vehicles is high, considering factors such as the battery decay rate, the frequency of car owners changing cars, and the manufacturer's warranty policy, we do not have to worry about whether to buy an electric vehicle due to battery problems. In fact, in terms of long-term cost of use and future development trends, electric vehicles are still a cost-effective choice. Like and follow don't get lost, we'll see you next time!
