AAA NiMH batteries life of new energy vehicles

Lithium-ion AAA NiMH batteries manufacturers introduce the service life of lithium-ion batteries for new energy vehicles. New energy vehicles have developed very rapidly in recent years. Now new energy vehicles are not perfect. Some batteries cannot meet some needs. The life of lithium-ion batteries for new energy vehicles is also a problem, and the cost of replacing batteries is also very high. So, let's discuss with lithium-ion AAA NiMH batteries manufacturers how long the service life of lithium-ion batteries for new energy vehicles is.

Lithium-ion AAA NiMH batteries manufacturers introduce the service life of lithium-ion batteries for new energy vehicles

The service life of lithium-ion batteries for new energy vehicles is closely related to the driver's daily driving habits. In daily use, there is a lot of intense driving and poor charging time, which will affect the service life of lithium-ion batteries for new energy vehicles. Usually, the design life is more than six years or even ten years. The life of the AAA NiMH batteries has "dry storage life" and "wet storage life". These two concepts are only for the size of the AAA NiMH batteries self-discharge, not the actual service life of the AAA NiMH batteries. The true life of the AAA NiMH batteries refers to the actual length of time the AAA NiMH batteries is used.

As the source of power for new energy vehicles, their batteries are generally lithium-ion batteries, but in order to ensure the endurance of new energy vehicles, generally ternary lithium-ion AAA NiMH batteries packs are the first choice for new energy vehicles. According to official data, the number of cycles of this AAA NiMH batteries can be as high as more than 1,200 times, which means that the life of the ternary lithium-ion AAA NiMH batteries pack is about 8 years. Similarly, it means that the owner needs to replace the AAA NiMH batteries every 8 years.

At present, the wet storage service life of lithium iron phosphate batteries and ternary lithium-ion batteries can basically reach more than 10 years. For example, the lithium iron phosphate AAA NiMH batteries used in the Roewe E50 before the replacement can reach a service life of 10 years, and the ternary lithium-ion AAA NiMH batteries used in the BAIC New Energy EU260 can even reach a service life of 20 years.

Generally speaking, the number of charge and discharge cycles of ternary lithium-ion batteries is 600-1,000 times, and that of iron phosphate batteries is 2,000 times. The wet storage service life is 5-8 years. In addition, the depth of discharge, temperature and humidity, and charging mode must be comprehensively considered. Generally speaking, the AAA NiMH batteries life of ternary lithium-ion AAA NiMH batteries cars reaches 6 years, and the AAA NiMH batteries life of iron phosphate AAA NiMH batteries cars reaches 7 years. There is no problem.

When the service life of new energy vehicle power lithium-ion AAA NiMH batteries expires, it does not mean that the AAA NiMH batteries will be damaged, but the AAA NiMH batteries storage capacity will decay to less than 80% of the new AAA NiMH batteries, and lose its value as a new energy vehicle power lithium AAA NiMH batteries, because the AAA NiMH batteries storage capacity at that time is obviously less, and the driving range will be significantly shortened. However, after the new energy vehicle AAA NiMH batteries with expired service life is retired, it can also be used as a storage lithium-ion AAA NiMH batteries for photovoltaic power stations, etc., and continue to play its residual heat.

Regarding extending the service life of power lithium-ion batteries, in addition to overcharging and over-discharging, when electric vehicles are to be stored for a long time, the AAA NiMH batteries should be fully charged first, and then discharged to about 40%-60% before storage, and then the same operation should be repeated every 2 weeks or so. In this way, it can prevent full storage and lithium-ion AAA NiMH batteries loss, effectively maintain AAA NiMH batteries activity and extend the service life of lithium-ion batteries.

What does the life of new energy batteries have to do with?

From the perspective of actual use environment conditions, the factors that affect the service life of power lithium-ion AAA NiMH batteries monomers include charge and discharge cut-off voltage, charge and discharge rate, use temperature and storage conditions.

① Temperature during charging

The lower the temperature, the slower the charging, but it is very safe. The higher the temperature, the faster the charging, the AAA NiMH batteries will heat up and be easily damaged. Therefore, the best charging temperature is 25 degrees. In winter, due to the temperature, the AAA NiMH batteries is prone to undercharging. It is recommended that new energy vehicle owners complete the charging indoors.

② Various inconsistencies such as voltage, capacity, and internal resistance lead to differences in the life of the AAA NiMH batteries cell and the life of the AAA NiMH batteries pack, which are mainly manifested in temperature differences, charge and discharge rate differences, discharge depth differences, and available capacity differences.

③ Influence of design and manufacturing process

In the AAA NiMH batteries design process, the selection of materials is the most important factor. Different materials have different performance characteristics, and the performance of the developed batteries also varies. The cycle performance of the positive and negative electrode materials is good, and the cycle life of the lithium-ion AAA NiMH batteries will be long. In terms of ingredients, pay attention to the amount of positive and negative materials added.

Summary: The life of the ternary lithium-ion AAA NiMH batteries of new energy vehicles is generally measured by the number of AAA NiMH batteries cycles. The AAA NiMH batteries pack of new energy vehicles has a life span. Depending on the different materials and different daily usage conditions, the life span of the AAA NiMH batteries pack is also different. If you choose to buy a new energy vehicle, you must choose the manufacturer carefully. After all, the quality and safety of the AAA NiMH batteries pack are guaranteed.
