Nick's Leaf Recommendations (2013 SV)
Posted: Sat Jan 09, 2016 12:15 pm
You can read my full articulation and reasoning here, but I would like to make the following recommendations to Nissan after driving the 2013 SV leaf for about 4 months:
- Provide settings that allow the user to tweak the B and D modes. Specifically, I would like to be able to adjust the D mode such that it applies no regenerative braking without the brake pedal and the B mode such that it applies full regen all the way down to a stop rather than inexplicably backing off starting at 45 MPH and applying power when the car reaches 8 MPH. I would also like to disable the creep because it's useless (and I would guess maintaining the creep is why the B mode is bastardized to fail to apply full regen at speeds below 45 MPH).
- Adjust the regenerative braking such that the car preferentially applies maximum regen before engaging the mechanical brakes to increase efficiency and reduce wear and tear. The current behavior requires that I whale on the brake pedal to get full regen at slow speeds (but it is apparent that the car can apply full regen at very low speeds).
- Provide a capacity indication in kWH rather than entirely arbitrary bar or percent system. Why even bother to give efficiency in miles/kWH if you don't provide kWH?
- Please don't use the "fog of war" technique of leaving drivers in the dark below 10% SOC. Both the guess-o-meter and percent capacity meter shut off at 10% and 5% charge remaining, which is rather annoying, requiring me to fire up the LeafSpy app to tell how much power I have left.
- Allow me to use FLAC files on the entertainment system. Allow the spare SD card slot to be used to hold media.
- The current behavior requires that you shut your car off before charging. First, the door to the charge port cannot be opened with the vehicle on. Second, the car will not charge if the charger is plugged in while the vehicle is on. Instead, the charge port door should be opened regardless of the state of the vehicle and the action of plugging in a charger should disable the drivetrain. Currently, I must shut off the car, open and plug in, and then turn the car back on to enter the "charge and stay warm inside" mode.
- Why is there a jungle noise that can't be shut off every time the car is turned on? Who thought this was a good idea?
- The car should provide a more accurate statement of how healthy the battery pack is. When I received my car it was within a few weeks of losing a capacity bar after its two year lease down in Georgia but the car gave no way to distinguish between its pack and a brand new one. It's also apparent that the relevant information exists in the car's computer system because the LeafSpy app provides a State-of-Health indicator for the pack in %.
- Lose the "world's most useless" tree meter and put something useful like efficiency in miles/kWH and kWH remaining in that location.
