The OEM price for the NLG664 is 6,640 Euros (excluding cables and VAT). Brusa will also require you to purchase a support package for 9,500 Euros (+ VAT). Hopefully that explains the lack of interest in the Leaf upgrade market.

Yes it's been done in the USA by a guy called ingineer. He also made a gas turbine Chademo station/range extender, upgrades EVSE's, and made a plugin Prius using A123 cells. He's a smart and busy guy!

érdekes QC párti következtetések

Érdekesség képen: ma Greentaxival utaztam. Jót beszélgettem a taxissal, nagyon jó fej volt, na de nem ez a lényeg. 96 ezer km volt a Leafben és mind a 12 pálcika meg volt még. Megérkezés után, megkérdeztem, hogy OBD-én ránézhetek-e? A LeafSpy 87%-ot írt SOH-re, 1954 DC töltés volt az autóban, 75 AC. A taxis elmondása szerint össze vissza van töltve.

jó angol megfogalmazás

https://speakev.com/threads/gids-or-soc.17248/

While technically true, real world experiences tells us each GID represents 80wh of usable energy in the battery. When a 24kwh leaf is new, and charged to "100%" on the dashboard, it will have a real SOC of about 95% (the battery is never truly full or empty, as that would damage it) and read about 280GIDs, that would also be 100% GIDs.

Fast forward two years when you have some battery degradation. When the dashboard says "100%" the SOC of the battery will still be 95% (it is as full as it will get) but the battery itself is now smaller, so it has only charged to 250 GIDs. 250 over 280 is 89%, so your GID % will be 89.

It's therefore a useful fixed unit to use over time in your own car, and compare with other cars too.

It's the metric I use when delivery driving. My car only charges to 82% GID now, and I can just about get 1 mile per GID % in slow urban driving. So long as it's not raining.

Király cikk.

http://insideevs.com/real-world-test-2013-nissan-leaf-range-vs-2012-nissan-leaf-range/

At 100kmh ground speed, it was estimated that this would yield a target energy usage rate of 4 miles (250 watts per mile) or 6.437 km per kWh (155 watts per km) without climate control. Based on Nissan’s published official range data from Nissan Technical Bulletin NTB11-076a, it was determined that a new car would travel 84 miles (135 km) until “turtle” mode (a reduced power mode to safely get the vehicle off the road before the battery disengages power altogether). This data is also consistent with extensive independent testing, both by myself and many others.

The car had two occupants for the test, both the owner Bob and myself. The combined total crew weight was 450 pounds (205 kg). The weather was absolutely perfect for the event with close to 70F (21C) degree weather, clear blue skies and light easterly breezes. In short, another perfect day in San Diego. Of course, thanks to a change in the 2013 LEAF, we were able to run the climate control fan without powering the heater or air conditioner pump, which we did

Both trip odometers, miles/kWh, average speed, timers, etc., were reset by the disconnect of the 12 volt battery earlier. Headlights were off, climate control off (except fan) and tires set to 36 pounds per square inch (2.48 bars) pressure.

A stored energy display meter (Gidmeter) was installed. A new LEAF in optimum condition will show 281 units reported by the LEAF’s automation, for a total of 281 x 80 watt hours per unit = 22.48 kWh stored in the battery. This value, referred to in the LEAF community as “Gids”, is alternately displayed as a percentage of 281 (281 would equal 100%). Of the 22.48kWh stored, the LEAF has 21 kWh available to use to propel the car and operate it’s various systems, therefore at 4 miles (6.437 km) per kWh of economy multiplied by the 21 kWh available will equal 84 miles (135 km) of range autonomy. The LEAF battery has an advertised capacity of 24 kWh.

One small surprise was that the dash SOC% meter matched the the Gidmeter exactly at LBW and VLB (17% and 8% respectively).

We drove about 69.2 miles (111.4 km) indicated (the odometer seemed surprisingly accurate compared to the speedometer) until Low Battery Warning (LBW) at 3.9 miles/kWh, and an additional 8 miles (12.9 km) to Very Low Battery (VLB). I determined based on many dozens of previous examples with the 2011 and 2012 LEAF that the car could drive another 4 – 5 miles (6.4 – 8.0 km) until Turtle mode, for a total of 81 – 82 indicated miles of range.

Not surprisingly, 81 miles divided by 3.9 miles per kWh equals 20.76 kWh of battery energy consumed to Turtle.
If the car could go 82 miles divided by 3.9 miles per kWh equals 21 kWh of battery energy consumed to Turtle.

If the car had gotten 4.0 miles per kWh of economy, it likely would have made 84 miles.

Conclusion:

There is no more nor any less range with a 2013 LEAF under these conditions that a 2011 or 2012 (when those cars were new with fresh batteries).
