Welcome to the Nissan (and many other brands) dealership (aka "stealership") network.



Opened the traction battery and found the Pre-charge resistor was bad. What caused it to fail?

Well the new precharge resistor should have been used while "booting" the HV bus when initiating charging. I would start it up. It is a car after all, if something's still broken, no sense in having it sit at this point as a paperweight.

Why would it need new brakes? Brakes being replaced at that point is extremely rare (e.g. person has to go on extended downhill grades, esp. starting from the top of a hill at full charge). If they did start at the top of the hill with a full charge, they likely didn't care about the battery either (e.g. didn't limit it to 80% or cut it off somewhere before 100%).

I'm still on my original brakes past 56K miles. I don't think you'll find many Leafers here who needed new brakes even at the 70 or 80K mile mark.

As for 2013 SV "no nav", that' s impossible. ALL '11 to '17 SV and SL trim have nav system. You can take a look at the Specs tab of http://nissannews.com/en-US/nissan/usa/ ... -press-kit to see the differences between '13 trim levels. The S trim (started with '13 model year) has no nav.

I'm still not sure why you're posting in this thread and I'm unclear if you know what you're getting yourself into.

Maybe you should start a new thread for purchase advice and answer my questions? Leaf may be unsuitable for you, or it might be just fine.

"Bay Area" means nothing. For those who don't live in the SF Bay Area, here's an example of variation in climate:
viewtopic.php?p=467541#p467541
viewtopic.php?p=464260#p464260

Remember, the EPA range rating on the '11 and '12 Leafs were 73 miles on a new battery, until the battery's dead. Let's assume this 9 bar car will be an 8 bar car soon and assume that means 30% capacity loss. 73 * 0.7 = 51.1 miles. At those 8 bars, you might be able to make it 51 or 52 miles at 60 mph w/no heater and no AC use on dry pavement w/the car coming to a stop at the end. See 8 bar range chart at viewtopic.php?t=4295. Go any faster, and your range will be even less.

Around here, it's really gotten crazy. I recently had the opportunity to buy a crashed Leaf (front/side collision, smashed quarter panel, mashed front-right suspension and dented/scratched side all over. Cost: 8000 euros. You can buy a perfectly good Leaf for 9500ish, I bought mine for 9000. It's just not worth it, and they're obviously exporting it.


Maintenance Vs Warranty

Oh believe me, I stay away from the dealership if I can. My cousin and his late dad have run a garage for 60 or so years. I don't mess with dealerships. I just wonder why Nissan (and all car makers) insist that you need to do the recommended maintenance to keep your warranty if its not true. I mean, I get the obvious answer (money) but it doesn't make sense. I'm in Canada, so by law here you're allowed to get your car serviced by any licensed mechanic even if its under warranty. But seriously, I'll get the battery check and I guess have them change the battery in my key and be done.


Is Nissan Connect (Carwings) worth it?

Silverfish wrote:Is Nissan Connect worth it? It seems weird to me to pay money to Nissan just to send them data that benefits them more than me. I don't need to start the heater or AC before I get in the car.

So what do people like about Nissan Connect?
What do I like:

Remote status: Where I work we have dozens of shared EVSEs. When I park in the morning half the time I don't get to plug in immediately, because the car next to me is already charging. With the app I can query the car around lunch to see if it's already been plugged in; otherwise I need to go out and plug it in (everyone who goes out to the garage swaps any plugs to cars waiting to charge, so often someone has already plugged me in).

Remote HVAC: Some days in the summer (this week when it's been >90°F every day) I want to turn on the A/C before I head out to the car to cool it off (even though it's in a garage and generally not too hot already).


What do I dislike:

It's slow. Really slow. Starting the Android can take 10-20s, and querying status can take 1-2 minutes.

It's unreliable. Sometimes I turn on the A/C while in the office and when I reach the car 5 minutes later it is still not on. Or it just doesn't respond at all. Or Nissan has an outage that lasts days to weeks.

The upgraded 3G modem has a serious bug that causes it to lock-up and continually consume power, eventually causing the 12V battery to die. (lots of threads on this). Although I haven't had to do a fuse pull to reset the TCU in 3 months or so.


Talking to other EV owners (we have many at work), it seems almost every remote access system suffers from slow and unreliable access, except Tesla.



DCFC Stations Bakersfield to the Sierra Nevada East Side Coming

Long overlooked by California's electrification effort, the vast area east of Bakersfield will soon be getting its first public DC fast charging (DCFC) stations for electric vehicles (EVs).

Drivers of non-Tesla EVs traveling east of Bakersfield currently find a veritable charging desert. There are no public DCFC stations east of Bakersfield until you reach Baker on the route to Las Vegas--and that station only recently opened. Tesla operates private fast charging stations, what they call superchargers, in Mojave, Inyokern, and Mammoth Lakes, as well as elsewhere.

Image

However, three programs are underway to locate stations on the east side of the Sierra Nevada. Two are being developed by the state of California. The third is being developed privately by the Volkswagen (VW) subsidiary Electrify America.

Two of those programs should see construction begin on several stations this summer. All stations should be completed by the end of 2019.

The California Energy Commission (CEC)'s Interregional Corridor contract GFO-15-603 awarded grants to two companies, ChargePoint and EV Connect, for installations in Tehachapi, Mojave, Inyokern, and Kramer Junction.

CalTrans, the state's transportation department, will be installing stations in its 30-30 program at safety roadside rest areas at Coso Junction, and Independence, as well as at its district headquarters in Bishop.

ChargePoint plans to install a DCFC station in Tehachapi in the Capital Cities development north of Hwy 58, another near Inyokern and Hwy 14, and another at the Kramer Junction of Hwy 58 and US 395.

EV Connect is responsible for installing a station at the airport in Inyokern and another in Mojave. They are expected to break ground on the Inyokern station this month.

VW will be installing a number of stations under its consent decree for Dieselgate. VW's Electrify America hired Black & Veatch to build the sites--the same people who built Tesla's supercharger network in the state. Though VW builds cars using the CCS standard, Electrify America will install both CHAdeMO, the Japanese standard, and CCS connections. They will future proof the stations with the capability of raising charging capacity up to 350 kW. Typically, non-Tesla stations charge at no more than 50 kW per connection. Electrify America's stalls will accept RFID, mobile pay apps, and credit cards for payment.

Image

All 600 chargers for VW's first cycle of development in California have been ordered. Manufacturers selected include ABB, BTC Power, Efacec, and Signet. Permitting for the selected sites begin this quarter.

Electrify America's deliberately vague maps don't provide much detail, but it appears they plan a station somewhere between Bakersfield and Mojave. They also have stations planned for somewhere between Inyokern and Olancha and a third station somewhere around Bishop.

CalTrans has yet to award contracts for its stations. Nevertheless, they are scheduled to be on line by mid-2019.

lkkms2 wrote:Interesting option. I wonder what was the impetus to develop this option.


They had some experimental rates that were similar to this one (three of them in fact), and I think this is the culmination of that. The idea being that the utility can separate their fixed cost from variable costs - so the consumer pays a fixed rate that covers the fixed cost to provide service to a residence, which is normally rolled into rates given to all customers (giving an arguably unfair advantage to those with PV who do not contribute to those fixed costs). Kind of how commercial customers have a demand charge.

It also makes evening EV charging a lot more reasonable as .23/kWhr is approaching the cost of an efficient ICE on gasoline/diesel. When I first switched onto EV-TOU2, the super off peak rate was .14/kWhr and peak was .28 - it's kind of ridiculous now with peak at .53+ (on non-grandfathered tou time periods). I can run a diesel or NG gen set for less than that.

Mechanical Key RFID?

The dealer may have just made a mistake. It was common for mechanical keys to have RFID chips in them before 'keyless' starters were used.

I'm not 100% sure but I do think that the key for a Leaf is purely mechanical since AFAIK its only real use is to open the doors when the 12V battery is dead and the car's electronics don't have power.

If the FOB opens and starts the car without the key present it's probably safe to say the key doesn't have any RFID capability.

I understand the purpose of a pre-charge resistor, but don't know how it's implemented in LEAF. I would want to know whether the resistor is always in the circuit or if there is a relay or contactor intended to remove it from the circuit before the main contactor closes. If so, then perhaps the precharge relay is stuck closed.


Direct DC Charging with Solar Panel

There was a project on here to do a home CHAdeMO at one point. I think that the JuiceBox folks were involved. That would be the approach to take since you have to have a charger than can generate the exact voltage the battery requires. It might be possible to hack the LEAF's internal charger, but you'd have to do a LOT of hacking. There's no way you'd simply be able to connect DC to the existing port and get it to work.

BTW. I've never understood why this concept keeps coming up so regularly. Since the charger has to do DC to DC conversions anyway, I can't believe there's any significant efficiency improvements to be gained. Certainly none worth this kind of effort, yet folks get all hot for it on a regular basis. Now a true car to home interface through the CHAdeMO would be more interesting, although if you actually drive the car, it's utility is kind of limited to emergency uses.

quick update

The new 12v battery is in and everything is working fine. One note that I (hope) help others. The time display on the odometer cluster was oddly switching itself to 24hour (military) time with the bad battery. I would re-set it o 12 hour, and it would go back to 24hr the next day. The time on the center cluster stayed at 12 hour.

Before I removed the old battery, I set the odometer cluster time display to 12 hour and removed the battery. After the new battery was installed, the time switched again to 24hr. Basically, if your car is switching to 24hr time, it seems like a pretty strong clue your 12v battery is dying.

thanks for the reply, cwerdna, you nailed it with one post, and I'm very grateful.

Or just get a JuiceBox and sell the Nissan EVSE.

Either of those solutions sounds good to me, both cheaper than either a CC or JB.

California being California is full of restrictions. In LA County you can not have anything that scans. That technically leaves out Amateur radio since most rigs can scan. I had a modified radio with full city frequencies since I had permission to use them. I just did not have a MDC ID,

LeftieBiker wrote: The car ALWAYS takes power from the battery; if you are replacing it fast enough from the EVSE then there will be either no net loss of power or the car will keep charging, but more slowly, while the heater is on.


I think Talock's question is: if you program the car to finish charging at 4 am, and you program the heater to preheat the car at 9 am, then by the time the heater kicks-on, the charge cycle in over-and-done with. Will the Leaf start a second charge cycle?

I think the answer is "no," but i'm not sure.


Nissan EVSE J1772 cable wire gauge?

I think I read a post somewhere, saying that Nissan had cheaped-out on later-model EVSEs, and started using thinner wire gauge from the J1772 to the EVSE. Does anyone recall if that's correct, and what year?

My J1772 cable (from 2017 Leaf) gets pretty warm, just charging at 12A... warm enough to melt through ice. If the ice re-freezes, then you end-up with a J1772 cable under a quarter-inch of ice, and it's very hard to get the cable free without using an ice chipper.
