How much does the battery of a new energy vehicle decay after 100,000 kilometers?
After driving 100,000 kilometers in a new energy vehicle, the degree of battery decay varies depending on a number of factors, such as the type of battery, usage habits, charging method, temperature and environment, and so on. According to some researches and actual cases, in general, after 100,000 kilometers of use, the capacity of the battery pack declines around 15%~20%. That is to say, if the range of your car was 500 kilometers when you bought it, its actual range may be reduced to about 400~450 kilometers after 10 years.
However, this rate of decay is not absolute, as each car owner's usage habits and charging methods are different, and the battery decay will vary. In addition, some new energy vehicles adopt advanced battery management systems and charging technologies, which can effectively slow down the rate of battery degradation.
If the battery has been left for 10 years without much use, is the degree of degradation high?
The decay of a battery is mainly due to its internal chemical reaction and loss of active substances. Even when unused, a battery will gradually lose its charge due to self-discharge and chemical reaction. In addition, environmental factors such as temperature and humidity of the battery will also affect its rate of decay.
Therefore, for batteries that have not been used for a long period of time, it is recommended to check their charge status regularly to avoid damage to the battery caused by too low a charge. At the same time, it is also necessary to pay attention to the storage environment of the battery to avoid high temperature, high humidity and other unfavorable factors on the battery.
In short, whether driving or placing, the decay of the battery is inevitable. Therefore, we need to take some measures to extend the service life of the battery, such as avoiding excessive charging and discharging, paying attention to the storage environment of the battery and so on.
There are many cases online: for example, a 2019 Tesla Model 3 Performance, which has been weathered and has sped 100,000 miles, still has 89.4% battery health. The range was around 275-280 miles when new, and is now down to 245-250 miles. It's a slight discount, but still as robust as a thousand miles considering its frequency of use and charging habits. This Model 3 accelerates from 0 to 60 miles in just 0.05 seconds slower than the new car, and as the years go by, the speed remains the same.
Therefore, for the battery degradation problem of new energy vehicles, car owners need to check the battery status regularly, avoid over-discharging and charging, and keep the battery in a suitable temperature environment to prolong the service life of the battery. At the same time, car owners can also refer to the car manufacturer's battery maintenance recommendations, to take a more scientific way of charging and use, in order to slow down the rate of battery degradation.
