That's basically everything you DO NOT want to do if you want to prolong the life of a lithium-ion battery! You get the longest life from a li-ion battery if you use only a very narrow portion of its total SoC range. See Table 2...

Clearly you don't know how aviation works. Name of the game in aviation is to get as little fuel in the plane as possible for each journey: only what's required, plus a reserve so that you can safely divert or go around if you have to. Anything extra is NOT loaded into the tank because it takes...

Personally, I don't think the Legislature is going to extend the Clean Air Decal program when all decals issued before January 1, 2022 are already expired and all decals issued after this date expire on September 30, 2025. The HOV lanes are already so clogged up with Teslas and Volts so as to...

I think 85% is a bit high and high SoC for sustained periods of time can kill batteries especially in hot weather. I'd keep the batteries at exactly 3.92V/cell which is 7/16 bars on the gauge, or around 55-65% in PHEV Watchdog (on the display with the % SoC and either Ah or kWh next to it). In...

Okay, THAT is consistent with what I am seeing: This is a very dumb design IMO. The problem is, the system thinks the batteries are capable of supplying up to about 60 kW of power, and they are. It just isn't very good for their lifespan to do this so often, and instead of using the ICE...

ICE can provide enough power AND speed < 120 kph might be some of the initial conditions that cause parallel mode to come on (the other possible initial condition being speed over 125 kph), but once already there, it will sometimes stay there down to around 70-80 kph, even when the ICE is...

I'd imagine that it has a lot to do with how much cargo it's carrying. It might do okay with just one person in the car, but throw in a family of 4 and some suitcases in the trunk for a week at Disney and it'll probably struggle. In fairness though, A LOT of cars struggle to get up that...

Yes but I've found that once it goes into parallel mode, it sometimes stays in parallel mode all the way down to around 80kph (50mph). While you'd think it would switch to series mode and rev up the engine because it's climbing, this is not always the case. Sometimes, it simply prefers to stay...

There's GOT to be a different part number for the fuel tank on the European model or something like that. But I don't understand why Mitsu would do that in the first place.

You've gotta compare to the best efficiency that is even possible, which is the Carnot efficiency. Then, you remove the isothermal expansion and contraction stages (not possible in a car engine, because the power to weight ratio of such an engine would suck) and you get some value for the...

Buy what? The PHEV CUV/SUV market has very few participants right now. Cayenne S E-Hybrid got better for MY 2019 and now has a 27 mi AER. But it still doesn't qualify for the California HOV sticker, which is the other reason I bought the PHEV. The PHEV is an imperfect car. So is every other car...

Mine is MY18, what's yours?

So, think about the area between Gilroy, CA and Santa Clarita, CA as a sort of "no stop zone" where no gas stations exist. This isn't the case in reality, of course, but in practice, the gas prices there tend to be crappy compared to the prices in the urban areas, because the stations along I-5...

But you make it sound like 40% efficiency is horrible, when in fact it is not. Even if you could make a perfect engine https://www.e-education.psu.edu/egee102/node/1942, it wouldn't be anywhere near 100% efficient, unless you somehow exhaust the gases into a temperature sink at absolute zero...

You wanna know who screwed up the i3 REX? The California Air Resources Board. https://insideevs.com/bmw-i3-rex-bevx-restrictions-plea-carb-unleash-rex/ I would just pull out a couple of quotes but the entire article is interesting. And the BEVx rules are really dumb (and it explains exactly why...

You'll almost certainly be able to do it. There were still 2 bars left on my fuel gauge, and an indicated ICE range of around 30-40 miles, when I refilled. Had I run the tank down to the point where the computer auto cancels Save mode and starts using battery, I could have gone around 335-350...

It's really too bad that no dealership would let me take a 300+ mile test drive with this thing. Anyone know what the thresholds are for causing the car to switch to series mode from parallel mode? I really think this is something that could be fixed with an ECU update...or with a user...

I am well aware of the power limits of both ICE and motors. But I have seen battery boost come on at relatively modest total power outputs of around 50-70 kW (which are easy to figure out because they provide a power gauge). The reason is obvious: the ICE is incapable of producing those power...

You shouldn't be blowing by people at a 30 mph speed differential is all I'm saying. If one person is going to blow by me at a 50 mph differential, there's not a whole lot I can do about it. But if EVERYONE is passing me at a 20 mph speed differential, it means I probably want to speed up. If...

The ICE should be at as low an RPM as possible, without lugging it, for the best fuel economy. Let me say that again: the ICE should be at as low an RPM as possible, without lugging it, for the best fuel economy. Engineering explained did an entire video dedicated to this topic...
