The older LEAF batteries
The older LEAF batteries prior to 4/2013 degraded more quickly because they are smaller and they are cycled more deeply and they tend to be left sitting at 100% charge more in the heat. This is still somewhat true for any batteries. It has nothing to do with active cooling. You spreading that misinformation is not helping matters. Active cooling is added to cars to prevent extreme heat and fires during recharging the cars. The LEAF batteries do not heat up and catch on fire so they do not require active cooling.
Chademo still outnumbers all the other quick charging services. Its a great method for car owners to charge and get back on the road. For example there are over 70 Chademo charger locations in Atlanta and the last I checked only 3 Supercharger locations. Similar ratio for most other major cities. No long lines for Chademos like people waiting for superchargers.
Nissan has done a poor job or no job at all of telling people how to select the proper EV for their lifestyle. You need a EV with twice the range of your daily commute, you need extra range for heat, AC, hills, and stops and extra errands. You do not need a 400 mile EV to get from paycheck to paycheck to fill your tank, you only need enough range for your next daily commute since it only take 2 seconds to plug it in when you get home and tomorrow morning it is all ready to go again.
