It appears that fast charging on the all-new 2018 Nissan LEAF may not live up to the first-generation model.

***UPDATE - April 7: Nissan has issued a response (via Transport Evolved) to this potential fast charging issue with the new LEAF. Here's the response in its entirety:

“The 2018 Nissan LEAF has charging safeguards to protect the battery during repeated fast charging sessions in a short period of time. While the safeguards may increase charging times after multiple fast charging sessions, they are important to maintaining battery life over an extended time period.”

We constantly field comments related to the Nissan LEAF's battery. There's a large group who insist that the lack of thermal management is a huge issue, which leads to accelerated degradation. On the other side of the coin, many believe that this idea is way over-exaggerated.

There are several factors that may or may not lead to both of the above opinions/theories having merit. The most obvious factor is related to weather (more specifically, average temperatures in the owners' geographic location).

This video mentions the new LEAF's TMS (or lack thereof), but instead focuses more on another battery issue. Actually, it's on fast charging. Or, more specifically, multiple fast charges in a single day.

YouTuber Jonathon Porterfield is careful to say that, of course, the 2018 LEAF can rapid-charge. In fact, the first few fast-charging sessions were just fine. It was after these initial charges that the slow down began to occur.

He admits that he was recently beaten by three hours on a 400-mile road trip by a Hyundai IONIQ with a 27 kWh battery pack. Additionally, his "old" LEAF completes a 500-mile road trip faster (due to charging speed) than the automaker's newest iteration of the car.
