Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

[Phil Hochstetler via EV]

Portland Oregon area just experienced a wind/cold event that took away
power from 150,000+.
I have a new in the box 7500 watt tri-fuel generator but had not set it up
yet (of course).
My model 3 was charged, but not setup with an inverter yet due to lack of
motivation, but our Rav4 Prime
had a full tank of gas and the 1500 watt built-in inverter that runs off
the high voltage pack.
I wired a short cord on the furnace (NG furnace) so we had heat as it was
12F out and ran a cord into the house
under the garage door so we could run a light or two and the 2 burner
countertop induction stove and refrigerator.
Pretty sweet.  In on mode (with doors locked with key), the rav4 would turn
on when the battery got low and recharge the battery.
After 24 hours, it used 1/8 tank of gas but we were warm and had
light/food.  I went out and got 10 gal of gas to fire up the generator
and the power came on before I got back.  Still fun.

Re: [EVDL] Momentary Pulse Switch

[Phil Hochstetler via EV]

That would be one option.  Another option is for the magnet to hold the
reed switch closed when the door is closed.
Thus your application could turn on the screen if the signal is interrupted
and turn off the screen if the circuit is complete.
If you are running the signal to an input pin, you just need a current
limit resistor and two wires and a 5v source.

Re: [EVDL] Clarification: Leaf battery warranty.

[phil hochstetler via EV]

For my 2016 30 kWh Leaf, here is the language in the Warranty Information
Booklet:

LITHIUM-ION BATTERY CAPACITY COVERAGE In addition to the lithium-ion
Battery Coverage for defects in materials or workmanship, the lithiumion
battery is also warranted against capacity loss below nine bars of capacity
as shown on the vehicle’s battery capacity level gauge for a period of 60
months or 60,000 miles, for vehicles equipped with the 24 kWh battery or 96
months or 100,000 miles for vehicles equipped with the 30 kWh battery,
whichever comes first. This warranty covers any repairs needed to return
battery capacity to a level of nine remaining bars on the vehicle’s battery
capacity level gauge. If possible, the lithium-ion battery components will
be repaired or replaced, and the original lithiumion battery will be
returned to the vehicle. If necessary, the lithium-ion battery will be
replaced with either a new or remanufactured lithium-ion battery. Any
repair or replacement made under this Lithium-Ion Battery Capacity Coverage
may not return your lithium-ion battery to an “as new” condition with all
12 battery capacity bars, but it will provide the vehicle with a capacity
level of nine bars or more on the battery capacity level gauge. This
Lithium-Ion Battery Capacity Coverage is subject to the exclusions listed
under the heading “WHAT IS NOT COVERED.”

So it looks like for a 24 kWh pack you get coverage for 60 months or 60,000
miles and for 30 kWh, 96 months and 100,000 miles (8 bars activates the
warranty coverage).
Here is a link to the manual:

  I wonder why their website is so skimpy, given they seem to be legit.
 Do
  they actually make the cells in the US, or just assemble the packs?
 
  I downloaded the spec sheet.
 
  http://www.enerdel.com/wp-content/uploads/2013/11/Cell-Binder.pdf
 
  What I see in terms of cycle life is not instructive.  The product page
  says:
  
 
 - Durability and low self-discharge; retains greater than 85% of
  initial
 
 capacity after more than 3,000 cycles at 100% DOD and 30°C
 ​
 
  They cut off charging at 4.1V and call that 100% SOC.  They say the
  nominal
  voltage is 3.6V.  This sounds like a LiFePO4 voltage.  But, it is a
 guess​
  - they don't reveal it.
 
  LFP is particularly vulnerable to deterioration at lower temperatures
 than
  other cell chemistries.  At 35°C (104°F) LFP starts to have accelerating
  deterioration.  It would be interesting to see how close to the 45°C
 line
  that they do show is to the 35°C line that they don't show.  The best of
  all information would be a family of curves that illustrates the region
  where deterioration accelerates.
 
  The graph on the spec sheet shows a 30°C curve that has only ~75% of
  capacity at 3000 cycles, not 85%.  So I am confused about that
  information.​
  ​
  ​
 
 
  I am going to digress to my pet topic here, cell testing:
 
  They have a C/2 charge and discharge rate. So the cycles are 1 hour
 start
  to finish.  They don't indicate a dwell time at the max SOC. So they
 take
  it up and immediately bring it back down.   Also the test equipment must
  be
  capable of sensing the decrease in capacity very precisely.  Not many
  people have this equipment, yet.  If understand why HOC is better and
  we push for it , then eventually it will supplant what is used now.  The
  video I keep linking to- Dr. Dahn discuss
  ​es​
  this in some detail.
 
  If high precision coulometry (HPC) is used, then you have better chance
 of
  knowing about the cells true durability in service.   WIth HPC y
  ou can have far few
  ​er​
  cycles and detect damage if you just hold at the fully charged state and
  temperature
  ​ - nothing much else matters​
  .  But
  ​,​
  if the idea is to show lots of cycles, not actually evaluate how NOT to
  operate the cells, then you run cycles like they have
  ​ (​
  and most everyone else in the business).​
 
  I am not say they are bad guys, but pointing out the problem with the
 bad
  old ways of testing cells.
 
  The problem that kills Li ion cells is the fully charged state
  a coinciding with higher temperature. The mechanism of damage is
 achieving
  a reaction activation energy when the cell is fully charged.  Below that
  temperature there is far less of a problem.   To evaluate the cell
 quality
  of design and manufacture you actually need to see at what conditions
 the
  cells deteriorate.
 
  You could take the same physical cells and use
  different electrolyte packages, test them with 1 hour cycles and see no
  difference, but with HPC and long dwell times you could
  tell which combination is better.  This is where the industry need to
 go.

   Hello EVDL,
  
   EnerDel makes a great cell and battery here in the USA.  I have been
 to
   their factory in the Indianapolis area many times.  I use the product
  just
   about every day.  I can write more but want to see if this message

   Mike,
  
   Caveat emptor.
  
   A US company, but I can't see any information on the website that
 tells
  me
   they have a good cell, modules or packs. It is rather uninformative. I
   can't tell if they are more than an outlet for a non-US company.
  
   To me the most important

I have a 24kWh Enerdel pack in my Think City.  I have 19k miles on it and
no noticeable loss of battery capacity (will be 3 years in Oct 2015).  I
also notice they have very good cold weather performance.  I have some PDF
presentations they made a few years ago about their battery technology
which is licensed from Argonne National Labs.I will try to find them
and post a link.

 I am in the process of deciding what type of Lithium batteries to use.
 Been through all the retoric on CALB, etc. Read the used Nissan battery
 threads and am leaning toward ENERDEL batteries for two reasons,, (1) They
 are a US company and (2) the discharge curve seems to be a steady declining
 ramp with a ‘soft’ end point.  EVOLVE Electrics is also very helpful.  I am
 well aware the company had a rough few years but it looks like they have
 recovered.  Looking for a 144 volt nominal/168V max system and 200 AHrs.
 So…does anyone have any solid experience using ENERDEL  batteries?
