Every week. Ternary lithium batteries are recommended to be charged as they are used, but should be fully charged to 100% at least once a week. Generally, ternary lithium batteries used in electric vehicles can maintain 80% of the original battery state after the number of hours. of charge cycles reaches 1000%. If the vehicle is equipped with a lithium iron phosphate battery, it is recommended to charge it as you go, but it should be fully charged to 100% at least once a week.
How many times can a new energy vehicle battery be recharged?
BYD's lithium iron phosphate battery has a lifespan of 12 years or 160,000 kilometers.
The number of cycles can reach 3,000 to 4,500 times; if you pay more attention to standard driving habits and perform regular maintenance of thecar, the battery can last about 12-15 years.
The lifespan of the ternary lithium battery is 4 to 6 years. The theoretical life of the ternary lithium battery is about 1500 times, and the actual life is about 1200 times. If the theoretical range of an electric vehicle can reach 200 km, the actual cruising range can reach 160 km, the maximum cruising range can reach 192,000 km, and the actual cruising range can reach 153,600 km.
Take the currently popular BYD Qin PLUS DM-l model as an example. This model is equipped with BYD’s latest blade battery technology; when its blade battery discharges to 80%, it can travel 165,000 kilometers, which is a safe bet. sufficient for ordinary car owners It can be used for 10-15 years; if it is the Qin PLUSDM-I with a pure electric range of 120 kilometers, when the blade battery diesarge at 80%, it can travel 360,000 kilometers, which is enough for ordinary car owners to use it for 20-30 years, which is already longer than the life of the entire vehicle.
How to maintain car batteries
In cold weather, it is recommended to choose a warmer room for charging and storage, which may Shorten charging time, charge more power and extend battery life.
To ensure long-term performance, it is recommended to avoid prolonged exposure of the vehicle to temperatures above 40 degrees Celsius or below minus 20 degrees Celsius. When the vehicle is not used for more than 7 days, try to keep the battery charge between 40% and 60%. If the vehicle is not used for more than 3 months, there is a risk of reduced service life of the power battery. It is recommendedMandated to discharge the power battery to 40% to 60% after Wally every 3 months, otherwise there is a risk of excessive discharge of the power battery and reduced battery performance.
The Pacific Automotive Network's mandatory national requirement for the number of electric battery cell cycles must be more than 1,000 times. Lithium iron phosphate can generally be used 2,000 times, while ternary lithium batteries. can be used more than 1,000 times. Generally, it can be used more than 1,000 times.
The cars are well maintained. The current power batteries used in new energy vehicles are mainly three types of ternary lithium batteries, lithium cobalt oxide batteries and lithium iron phosphate batteries. There is a lifespan. The lifespan of an electric battery is measured according to the number of cycles.The more it is charged and discharged, the shorter the battery life will be. For the number of cycles of power battery cells, the national mandatory requirement should be more than 1,000 times. Lithium iron phosphate can generally be used more than 2,000 times, and ternary lithium batteries can generally be used more than 1,000 times.
The number of cycles mentioned here does not mean that it can only be charged 1000 times, but refers to the number of deep charges and discharges. That is, the number of cycles is only indicated when the battery is almost exhausted. exhausted then fully charged. If the battery is depleted, continuing to charge when it is completely depleted does not actually count as deep charging and discharging. In order to give everyone a more intuitive understanding, let's take the BAIC EU series as an example.
The capacity of the ternary lithium battery dThe Lotto quick-change version of the BAIC EU series is 45 kWh, and the NEDC full range is 300 kilometers. Assuming our mileage in a week is 600 kilometers, then it is. equivalent to one week It requires 2 deep charges and discharges, and 104 deep charges and discharges are required per year. The number of deep charge and discharge of ternary lithium batteries is about 1,000 times, which means that the battery life of BAIC EU series. can theoretically reach around 10 years.
