Talking about the two kinds of attenuation of power button cell battery cr1620

Two ways of attenuation of power batteries and their impact on electric vehicles

There are two kinds of attenuation of power button cell battery cr1620 in electric vehicles: one is the attenuation caused by the cycle of power button cell battery cr1620, and the other is the attenuation of power button cell battery cr1620 in low temperature environments. The former is the performance of the power lithium-ion battery at the end of its service life, and the latter is the performance of the power lithium-ion battery in low temperature environments. Both have a huge impact on electric vehicles. Power button cell battery cr1620 are the power source of electric vehicles. After attenuation, the energy storage and charging power of power button cell battery cr1620 will be directly affected. In the case of electric vehicles, the mileage decreases and the charging speed slows down. The normal use of electric vehicles will be greatly affected. Let's take a look at the specific situation of these two attenuations.

As the number of cycles increases, the energy battery will decay. To a certain extent, the power of the battery will decrease a lot, and it is generally necessary to replace it. The current replacement standard is to reduce the function of the power lithium-ion battery to 80% of the original.

The current mainstream lithium iron phosphate batteries and ternary button cell battery cr1620 are reduced to 80% of the standard replacement amount: the average number of cycles of lithium iron phosphate batteries is between 1500 and 2000 times. The number of cycles of ternary button cell battery cr1620 is generally between 1000 and 1500. The number of cycles from one charge to one drain. For example, you can complete 5 cycles per month. We use 1000 cycles. The battery life is about 200 months.

How to judge the attenuation of power batteries: In the use of cars, if there is a significant drop in the driving process, the charging or virtual power is serious, then it may be a problem with the power battery. Just like our mobile phones, there is often a phenomenon in the use of late return. Continuous charging is not enough, or it looks full, but the power will be lost quickly. The same is true for electric vehicles. If there is a problem with the battery, similar things will happen. From these abnormal aspects, the degree of attenuation of the power lithium-ion battery can be roughly judged.

Low temperature attenuation of power button cell battery cr1620: The external ambient temperature is low in winter, and the chemical reaction of the power lithium-ion battery of new energy electric vehicles will slow down. This will lead to slower charging speed and shorter travel. When the external temperature is around minus 10 degrees Celsius, the battery's cruising range will be shortened by 30%. The lower the temperature, the more severe the battery attenuation. This situation is a low-temperature attenuation phenomenon, which can also cause great inconvenience in using electric vehicles.
