Re: 60 kWh LEAF Introduction Placed on HOLD

Thu Dec 06, 2018 3:02 pm

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.

https://insideevs.com/heres-nissan-employs-active-air-cooling-e-nv200-battery-pack/
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 ;)

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.

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