    Pressure testing batteries

    I worked as a test engineer for a defense contractor where we performed "Leak Down" testing on our underwater vehicles. This involved an initial vacuum purge and hold at reduced pressure followed by a dry nitrogen back-fill. This was repeated at least twice to reduce the chances of any moisture...

    Does ECO mode really reduce HVAC power consumption? What about the stealth "partial recirc?"

    From my understanding "ECO" mode simply places a little hysteresis (softens) the response of the accelerator pedal. This is likely because electric motors are most in-efficient when just beginning to turn. The result being that the in-rush of current when the motor is beginning to spin up is...

    Buying a 2019 SL Plus

    Some 2019 Leafs had issues with their entertainment "head" units. Mine has an intermittent rear-view camera that goes all blue or all pink occasionally. Other than that, my Leaf has been absolutely stellar for nearly 50k miles. I'm still showing better than 90% SOH.

    Increasing ground clearance

    The article mentions that the suspension remained entirely stock. Absolutely no modifications. Not sure how this was possible but I'll have to take them at their word. They did say that some sheet metal work was necessary as the fenders had to be opened to accommodate the 39 inch wheels. The...

    Increasing ground clearance

    Sweet.....Nice job. I wonder if it's this easy to do this to a Nissan Ariya. I'd love to have one converted to look like the one used for the recent North Pole to South Pole excursion. I love the look of the "Beast Mode" Ariya...

    Any reason not to buy 20/21 62kwh Leaf (UK)

    Most EV battery failures can be traced to abuse (intentional or otherwise) such as frequent HVDC charging when the battery pack is hot. They also fail from accidents or other types of physical trauma and from good old poor manufacturing processes. Tesla's latest BMS algorithms, incredible Active...

    Strange uneven tire wear

    I listened to Niki on her Transport Evolved YouTube channel a few years ago. She switched to Nokian EnTyres on her Nissan Leaf, so I replaced my worn-out Michelins with a set about two years ago. They have done well for 20,000 miles so far. They are known for having a very low rolling resistance...

    Gear selector stiff

    He, he, sounds like someone "inadvertently" attempted to lubricate the shifter with something like soda pop or a milkshake. I've done this as well,..........sadly.

    Building a 2012 Leaf with 2015 components

    I sold my 2015 a couple years ago so I cannot compare it directly to the seats in my 2019. From what I can see with my 2019 (and what I remember from my 2015), they seem to mount to the floor in the same manner. Heated and electrically adjustable options aside, the seat's mounting seems to be...

    2018+ ZE1 Battery Extender

    Interesting idea. However, adding additional batteries in a manner that allows for them to come under the control of the existing BMS hardware and software would be most difficult. You'd likely have to treat the additional battery pack as a completely separate entity especially when charging and...

    What's a realistic time frame, or should I take the buyback?

    Be advised that the 2016 and 2017 (30kWh) models have a known software bug in the BMS algorithm that incorrectly calculates the battery pack's health and capacity degradation (SOH). The 30kWh models require a software upgrade (that is available) that very few have received. Dealers cannot be...

    Dealer's unbelievable trade-in offer...

    Don't believe it. NEVER TRUST A DEALER. Go to the CARGURUS website and search for Nissan Leafs. You'll see far less attractive pre-2015 SV Leafs often going for over $10,000 and "like new" 2018 SV and newer Leafs going for well over $18,000. You're being lied to. I found this out the hard way...

    Amperage to charge for Level 2

    The breaker simply determines the amperage trip point. Beyond that it does not regulate current. Installing a lower amperage breaker simply lowers the trip point leading to the breaker tripping far more often - not good for AC breakers. Beyond the safety issues, replacing a 50 amp breaker with a...

    12V battery died, SOH and SOC messed up after replacing 12V

    The 12V accessory battery in the Leaf doesn't see anything close to the up and down cycling that it would see as a starter battery in an ICE vehicle. This is why they can easily last well over 5 years in the Leaf if properly maintained. The issue as I see it is that if the 12V lead acid battery...

    Battery Degradation of a high mileage Leaf

    It's quite possible that using a 10-20kWh DCFC charger will lead to accelerated battery degradation under certain conditions. The Leaf batteries (especially those of 40kWh or less) if driven for extended periods of time above 80 mph can raise core temperatures appreciably. This is especially...
