How to judge the true mileage of a new energy vehicle?

How to judge the true mileage of a new energy vehicle? The core component of a new energy vehicle should belong to the automotive power lithium-ion battery. As the energy source of a new energy vehicle, its quality directly determines the driving distance and application performance of the vehicle! How long is the service life? According to national regulations, the power lithium-ion battery capacity of electric vehicles decays below 80% of the new battery state can be regarded as the end of the power lithium-ion battery life. According to battery standards, the life of a ternary lithium battery depends on the number of cycles of the battery, and the capacity of a ternary lithium battery decreases with the increase in the number of charge and discharge. In related laboratories, the ternary lithium battery is continuously charged and discharged at a charge-discharge rate of 1C. After charging 1000 times, the battery capacity drops to 80% of the new battery state. According to the current technical level of ternary lithium batteries, the capacity density of power lithium-ion batteries is commonly used for electric vehicles is 260wh/kg. Calculated according to the energy density, 20,000 kilometers a year is calculated, and the calculation is charged according to the shallow calculation. The cycle life is at least 1,000 times. . If used properly, electric vehicles can last at least 5 to 8 years. What are the factors that affect the life of a ternary lithium battery? As for what factors will affect the service life of a ternary lithium battery, Hydrogen Cloud Chain believes that this should be analyzed from the structure and application of the battery itself, such as: battery materials, Use environment and best operating conditions. Specifically, during use, due to improper use, an irreversible electrochemical reaction occurs in lithium batteries, resulting in a decrease in capacity. For example, the decomposition of the internal electrolyte of the battery and the loss of the internal activity data of the battery will directly lead to a sharp decline in the life of the ternary lithium battery. Of course, the battery life of an electric vehicle does not mean that the battery cannot be charged, discharged, or cannot, but the current discharge of the battery and the decline in the state of the new battery, continued use, will bring users a bad car experience. Because the power lithium-ion battery life standard was formulated a few years ago, when the battery capacity was small, the driving distance of electric vehicles was short, attenuating to less than 80% of the new battery, and the driving distance was much shorter. For example, the battery has decayed to 80% of the 200-kilometer driving distance and needs to be charged after 160 kilometers. The driving distance of current electric vehicles is already relatively high, and the 20% attenuation of the user's car is not that big. How to judge the actual driving distance of a new energy vehicle? If the cell cycle of the standard resolution ternary lithium battery life judged above, this cycle, the cycle time of the battery is fully charged, and the complete process, if it is transformed into A driving range, as well as the distance between electric vehicle conditions and electric gasoline-fuelled vehicle travel. Travel distanceBecause there is a certain difference between the travel distance and practice of gasoline-fuelled cars, plus every complete charge and discharge, the battery capacity will be reduced, and the attenuation will be real-time. The travel distance of battery electric vehicles cannot always maintain the new battery state, so continue to drive Based on the mileage of the car company, it is feasible to be closer to 7 times the total distance of the battery life cycle of electric vehicles.
