How to solve the battery capacity decay -Lithium - Ion Battery Equipment

According to foreign media reports, Nissan has released a new plan to replace the used batteries of LEAF models with "refabricated" batteries. Compared with the new battery, this "remade" battery gives users a certain price discount.

After a long time of use, the capacity of the on-board battery of an electric vehicle will decline, which is unavoidable. Normally, the decay rate (decrease) of battery capacity is only a few percentage points, but some Nissan Leaf owners reported that their on-board battery capacity decayed at a relatively large rate.(Lithium - Ion Battery Equipment)

The Nissan Leaf has promised to consume 66 percent of its electricity for every 100 miles driven for 96 months (8 years). However, according to a recent study, the capacity of the original 24kWh battery will decay by 20% of the original battery capacity after 5 years of use.

Interestingly, the research report also pointed out that Nissan's original 30kWh battery has even higher attenuation than the old battery. In contrast, earlier Tesla Model S and Model X models performed better, with a battery capacity decay rate of only 10% after the mileage reached 150,000 miles.

In order to alleviate the problem of battery capacity fading, Nissan has released a new battery replacement plan, which will be implemented first in Japan. If Nissan owners buy the new original 24kWh, 30kWh and 40kWh on-board batteries, the prices they need to pay are 650,000 yen (about $6,200), 800,000 yen (about $7,600), and 820,000 yen (about $6,200). $7800).

Luckily, it's only 300,000 yen (about $2,850) to buy the remastered battery.
