What is the degradation of the Nissan Leaf II battery? For our reader, the loss is 2,5-5,3 percent. 50 km each • CARS

26.05.2022 /

One of our readers, Mr. Michal, rated his 50th generation Nissan Leaf in terms of battery wear. It looks like the car has lost about 2 to 3 percent of its battery capacity on a XNUMX-kilometer run. This bodes well for the coming years of operation.

  • Loss of battery capacity in an electric car using the example of Nissan Leaf II
    • 2,5 to 5,3 percent power loss after 50 kilometers

A few days ago, we described the situation of an Australian whose Nissan Leaf I (ZE0, 50th generation) lost about 143 percent of battery capacity / range over five years of light use. The salon became interested in this topic only seven years later, when the batteries ... the warranty had already expired. During this time, the owner drove about XNUMX thousand kilometers.

> Nissan Leaf. After 5 years, the power reserve dropped to 60 km, the need to replace the battery was equivalent to ... 89 thousand. zloty

Our reader, Mr. Michal, drives a Nissan Leaf II (ZE1), the second generation of the car - he has driven over 50 kilometers. To measure battery capacity, he charged the car from 1 percent to 100 percent. The wall charger showed 38 kWh of energy sent to the battery..

The total battery capacity of the Nissan Leaf II is 40 kWh.but user accessible / useful / clean о 37,5 kWh. These values ​​depend on temperature, measurement method and previous use, so they may differ slightly depending on conditions. So, we have the following data:

  • 99 percent of the battery capacity corresponded to 38 kWh, that is, 100 percent up to 38,4 kWh,
  • net power 37,5 kWh,
  • losses for the whole process include do 5 percentand probably less - the Leaf is a worthy study here because it doesn't have a battery cooling system that would consume extra power.

2,5 to 5,3 percent power loss after 50 kilometers

Based on the data presented above, it is easy to calculate that the battery capacity is currently around 36,6 kWh, with the result that degradation is only 2,5 percent. That is, from the original 243 km after 50 thousand kilometers there should be about 237 kilometers. After another 50 6 kilometers, he will travel another XNUMX kilometers - and so on.

Let's check out a pessimistic realistic scenario. Suppose the home charging station has a loss of about 8 percent, as is usually assumed for vehicles with actively cooled batteries. In this case, the Leaf we are describing has 35,5 kWh from the original 37,5 kWh (-5,3%). It means that after 50 thousand kilometers, the loss of range will be 13 kilometers..

> How long should an electric car last? How many years does an electrician's battery replace? [WE WILL ANSWER]

Assuming that the battery should be replaced at about 70 percent of its capacity, the car will approach that value at around 280 kilometers. The only question is whether the owner will decide on this, because on one charge he will still drive about 170 kilometers ...
