Last winter when I was using my OBD2 LELink dongle to measure prospective Leafs in used car lots, I found that I had to power cycle the phone to get LeafSpy to connect to the dongle if I'd used the dongle in a different Leaf since my phone's most recent restart. (I figure this may be a feature, preventing LS from accidentally reporting on the wrong Leaf if you're in a parking lot with other cars that have OBD2 dongles plugged in.) Granted, I was using an iPhone and you're using Android, but the symptom matches.

First ev, want used one
Range of Leaf is fine I hardly drive,live in hot area Las Vegas.
Considering a used leaf but don’ T understand battery on a used one. Do I continue paying $125 or can I buy it?
Can it be plugged into a 110 socket in garage?
Are there things that frequenty give trouble?
Should I just buy on price not worry about age?
Any suggestions are welcome.

Removing the shroud to test the increased cooling is a good start, but the ultimate goal might better be to incorporate adjustable air intake scoops at the front of the shroud, so the cooling can be easily enhanced in hot weather, and reduced in cold. Also keep in mind that in some cases more airflow will mean more heating instead of more cooling, if the ambient air temp is above the battery temp. I'm keeping my 2018 SL in a cooled (at night) garage, so I actually want as little airflow over the cool battery in Hot weather as possible, at least on short trip.

I know some people have had better experiences with it, but for many people who paid to have their TCU upgraded it's been a huge PITA.


How can I tell if my car's TCU has been upgraded? I've only had it for a couple of months. I do believe it's still sending info to Nissan, from the nag screen that appears when I turn the car on.

Whenever I've done the analysis the results have always been the same, the best average speed is obtained when the output power is the same as the input power.

To keep the heater from running, you want the lowest resistance resistor switched in parallel with the temperature sensor so that would either be position 1 or 2 (not off). The OFF position is for normal heater operation.


not sure what you are talking about but i have my switch (mod from Tor) OFF during the whole summer

Looks like it's either a JuiceBox or Clipper Creek for me.

Yes, basically any EVSE will work on 208v.....except the '18 OEM Leaf EVSE :roll:
As you sound a bit technical, I'd really suggest a Juicebox. Not that the Clipper Creek is bad, it's just the Juicebox is so much more flexible. I've ran my Juicebox down to less than 200v with no issues. It's also nice the Juicebox allows you to adjust the maximum output current, CC EVSEs are always maximum, unless your car calls for less.

I got "46B24L 12V 46Ah 650CCA Lithium Iron Phosphate Battery LiFePO4 for Automotive Car" from ebay and I like it a lot. In addition to the main 46AH battery, it contains emergency 10AH battery you can activate in case of main battery was discharged fully with small switch on the battery. This feature makes carrying lithium battery booster redundant and the weight is only ~9lbs. Exact fit for 51R size battery. Before the change the morning voltage would be 12.3V on OEM battery, on this LiFePO4 - I get 13.35V on first morning and second morning if car is not used and 13.45V right after trip. I have a few battery testers and they show OEM battery is good, but the real life performance suggests otherwise. I doubt it will make it till charger kicks in 5 days, if left unused. I never had 12V battery failure though. The sellers also sell 46B24R, but it has terminals reversed. It fits, but terminals would be a bit off (negative will be at angle) when mounted.

Greetings. I picked up my 2018 Leaf SL yesterday and am very impressed with the ride and handling. After 68 miles of use, there is still no display of estimated range in miles. The battery indicator image appears to be working properly. Is a certain number of miles driven or charges completed required before an estimated range in miles is displayed? Is a charge to 100% required before estimates are displayed.
Thank you.

Jbuntz, sorry if I missed your explanation somewhere earlier, but if you were at 8 bars didn’t you qualify for a new battery? Were you required to do this SOftware downgrade (I mean Upgrade :o )


I missed the cut off by a couple of weeks :(


There was no cut off. The reality is Nissan was getting degraded packs and upon testing, they were well over the 8 bars required for replacement so the people who did get new packs, got them thru a Nissan SW error. not from true degradation.



My battery has still prematurely degraded even after this update. 87% SOH on a two year old car with 28k miles is unacceptable. Lease is up in February so not really a problem for me. Had I purchased it would be a different story. By comparison a 2 year old Tesla with 28k miles would probably have only around 2% - 3% degradation. It baffles me that there are members on this forum that still defend Nissan's crappy batteries!

Gerry,

Assuming I get the heater control switch kit installed soon ( it already arrived in the mail):

Before installing, do I need to pre-set the HVAC to a specific setting?

After the install, considering its hot here in Austin right now (~100), I will keep the AC on 60 degrees and lowest fan setting once cooled, then what setting do I put the switch at, 0, 1, or 2? Will that change in the winter months?

Thanks.


You want to use Position 1 (330 ohm resistor) to keep heating elements from being energized inadvertently while using A/C. Position 2 (2.2 kohm resistor) would allow the heating elements to be energized, but keep the fluid temperature lower than normal. The OFF position allows the heating elements to heat the fluid normally and will reduce range under certain ambient temperature conditions. Therefore, I recommend Position 1 to avoid inadvertent heating element use unless you need heat. Choose Position 2 or OFF depending upon cabin heat/defrost needs. Use OFF to get maximum heating.

You can try updating charging stations in the Navigation/CarWings system. Touch the blue (Zero Emission) button to open the energy menu and the touch the Update Stations icon. The telematics unit is working if it updates stations.

The range isn't going to be that much. 11 bars showing means a full 10 bars, plus an unknown extra bit. I'd pass on that car, as it came from a hot climate.

Renewable natural gas produced in California by CR&R flows into SoCalGas pipelines for first time
http://www.greencarcongress.com/2018/07/201807030-socalgas.html

Southern California Gas Co. (SoCalGas) and waste management company CR&R Environmental (CR&R) announced they are now injecting renewable natural gas produced at CR&R’s anaerobic digestion facility in Perris, Calif., into SoCalGas pipelines. This is the first renewable natural gas produced within California to be introduced into SoCalGas’ pipeline system.

Renewable natural gas is a carbon-negative fuel produced from waste that can be used in trucks and buses, to generate electricity, fuel heating systems in home and businesses, and for cooking. The renewable natural gas from CR&R’s digestion facility is used to fuel about 400 of CR&R’s waste hauling trucks.

CR&R is producing renewable natural gas using organic waste collected in Southern California cities’ green waste bins and processed in an anaerobic digester believed to be the largest and most automated in the world. This biogas is upgraded to the same standards and specifications of traditionally-sourced natural gas and then put into a new 1.4-mile section of SoCalGas pipeline. . . .

Renewable natural gas from other states has already begun to clean the air and reduce greenhouse gas emissions in California’s transportation sector, which accounts for more than 80% of smog forming emissions and about 40% of greenhouse gas emissions in the state. The latest generation of natural gas engines for heavy duty vehicles can reduce smog-forming emissions by more than 90%. When fueled with renewable natural gas, they can reduce greenhouse gas emissions by 80% or more. . . .


Skangas supplying liquefied biogas (LBG) to tanker Fure Vinga
http://www.greencarcongress.com/2018/07/20180703-skangas.html

. . . The Swedish LBG was delivered to Furetank’s M/T FURE VINGA from Skangas’ parent company Gasum’s biogas facility in Lidköping. The fueling took place at the port of Gothenburg, transferring the fuel directly from a tanker truck to the ship.

The FURE VINGA was delivered from the ship yard in April this year and is one of two vessels in the company’s fleet powered by liquefied gas. Furetank has been using LNG as fuel since 2015 when the FURE WEST was converted for dual-fuel.

Together with partners Furetank is building five further sister vessels to the FURE VINGA, all of which will be dual-fuel and can be powered by LBG when the fuel is available. The vessels will be trading in North Europe and will benefit from Skangas’ LNG supply network in the region. Skangas is already supporting Furetank’s other LNG-fueled vessels in ports and at sea. . . .

Firstly, biogas is produced through the processing of various types of organic waste. Secondly, the gas is purified and upgraded to approximately 97% methane. This process takes place in Skangas’s parent company Gasum’s biogas facility in Lidköping. The biogas is further being liquefied by cooling it to a temperature of minus 160 °C for transportation by trucks to customers.
