60 kWh LEAF Introduction Placed on HOLD

[scottf200]

The 60 kWh LEAF is supposed to be air condition cooled similar to the e-NV200 ... which supposedly handles multiple DC charging fine.

FWIW I read air blown past with a fan.

Woohoo! Nissan engineering is really stepping up to the plate, or they were given a $9.99 budget per car.

I would never buy an EV cooled by A/C'd air or just air vs liquid but LGChem is pretty reputable and must have approved the 60 kWh LEAF cooling ... they wouldn't mess with their (LGChem) reputation.

Nissan issued this statement on the active air-cooling/heating system in the e-NV200 battery pack:

“As in LEAF, the battery pack comprises 48 modules with a nominal capacity of 24 kWh, but it incorporates a bespoke cooling pack that operates automatically during quick charging.”

“Due to more compact packaging and because e-NV200’s duty cycle is likely to be quite different to LEAF – it is anticipated that the vehicle will be operated intensively during the working day and there will be greater use of Quick Chargers to minimise down time – cooled air from the vehicle’s heating and ventilation system is channelled over the battery cells to ensure optimum charging conditions at all times.”

“Conversely, in cold weather, the vehicle’s HVAC system wafts warm air over the battery, again to ensure it reaches its optimum operating temperature as quickly as possible.”

Yes! And as you know, that system has already been a failure in hot climates with the Kia Soul. Most of the time, a vehicle just sits, and as we know, it is during this time the battery gets toasted.

Quiz; What is the optimum temperature for 2018 LEAF batteries for fast charging?

Its higher than you think

Its higher than you think

You would have to qualify “optimum”.

Optimum for high speed is a very hot battery
Optimum for long life is a cool battery

No rocket science needed.

Correct but the question was about "fast" charging

So you figured the fast battery degradation did not need to mentioned.

So helpful

I think that has had plenty of publicity. But its Winter now and priorities change.

I don't see Ghosn as the reason for the delay, but as the reason the LEAF effort persevered as long as it has. I've always had the impression that Nissan were of two minds when it came to LEAF, at least outside of Japanese market. The pro-EV mind is gone. The foot-draggers remain.

The foot draggers are at Nissan. They came out with the Leaf in 2011. Since that time a company that had never done more than modify a car has released three electric cars, to generally widspread acclaim. And the only thing Nissan accomplished over this period? Increased the range of its car by 50%.

Nissan was supposed to kick this EV revolution off but they have not put more than a modicum of attention to it since they started.
