Turkey did it some years ago (2005). Removed six zeroes and named it something like “new lira”. Then named it back to “lira” after most of the old money is out of circulation.
20 years later, I think some more zeroes are available to be removed :)
And if it’s the very first gen of the Leaf, then, as far as I know, they don’t have thermal management for the batteries. So it greatly stresses them both for discharge and charge and that manifests as reduced capacity.
Lithium cells are happy when they are around 20-25 degrees Celsius (about 75F?) but they don’t enjoy when it’s hot or cold. Likewise, they don’t enjoy full charges and discharges which I’d guess more probable in a smaller range car.
All in all, the first gen Leaf might not be a good benchmark for a more modern EV. Many things should be better now.
I think that applies to many other electronics they sell too. I find them pretty well engineered overall.
My guess is that it’s because they sell any particular piece of hardware in millions and it’s in their best interest to design it properly so they don’t have to deal with the returns.
Interesting approach. I have a feeling that this is intended for sparsely built houses (the typical american housing maybe?) since in a dense European city I’d imagine it would pick up tons of cell phone signals from other people in their own homes or, say, from people visiting the downstairs coffee shop terrace.
You can but it isn’t efficient. You lose (V_in - V_out)*I_led Watts to heat if you use a linear regulator.
You might ask why not connect them in series and get the voltage difference as small as possible. But the “forward voltages” of LEDs are highly temperature dependent and car battery voltage is (somewhat) engine rpm dependent (might swing between 12 and 13.8V between no rpm and some rpm. It’s kept flat at 13.8V)
They might turn off/block egr which reintroduces exhaust gasses to intake to reduce combustion temperature. The upside of this system is that it reduces NOx emissions, the downside is that you’re bringing a lot of soot inside the engine. They are abrasive.
Combine egr with pcv, which directs positive crankcase pressure into the intake, you get an oily sooty mixture caking inside the intake.
Combine this with swirl flaps, which create a small tornado at lower engine speeds for better combustion, you get caking on the flaps and your intake becomes halfway clogged.
These are my annoyances. But to be honest, it didn’t require cleaning even after 250.000 kilometers of driving. I saw the caking while doing some other work, but the engine was running fine
But there’s also the dpf, and the adblue stuff. Dpf is an issue only if you use wrong kind of oil and clog it. I’m assuming people remove the dpf to run coal, as it will get clogged extremely fast if you detune your engine. It might also be an annoyance if you want to mod the engine, but not sure on that front. And adblue is yet another thing to fill every now and then. No experience with that, but I assume it might annoy some.
