Electric motor under powered?

[ontheroad]

Powerboost e-motor is rated for 47 horsepower (34.5 kw). However, with obdlink monitoring, I have never seen that the hybrid power usage reaches 34kw (other than when it is kicking start the ICE) before engaging ICE. Also, as battery SOC approaches 45%, the switch point gets further reduced (aka hybrid power usage switching to ICE much lower than the peak power).

Is this done to protect the motor or to protect battery (or both)? It seems that it would leave potentials out.

It's to protect the battery. It's very small and thus has tons of discharge cycles, it needs to be kept in a very narrow SOC range to keep it from dying.

Now look, we can't have clear concise and accurate posts here. The is the dam@@ internet and we can't have that kinda thing going on. At the very least you need to challenge the battery used, second guess the engineers, or berate the owners expectations. Get with it man!

im trying to get my @$$hat count up. No one has called me one in a few weeks, I’m slacking.

Sorry for the provoking question . If it is indeed that consideration, it would speak to what I suspected: that the battery is the bottleneck. So just in case that battery tech tremendously improves in the next 10 years, there is a hope that the hybrid would get much more economic? (Say that we have infinite supply of electricity from the battery, i'd imagine that the average fuel economy can easily get to 26?)

? Exactly.

It's not a bottleneck because it does what Ford wanted it to. Like you, I bought a hybrid wanting better fuel economy. What I got was more power for the same fuel economy. Ford's research told them that truck buyers didn't care about fuel economy; they cared about power. So, the system is designed to allow the electric motor to add an oomph of torque in short bursts when called upon. The ability to drive in electric-only mode sometimes was an afterthought. I do think Ford's research was wrong based on the number of people on THFB who complain about the PowerBoost fuel mileage and talk about how to hyper-mile it.

Ford could easily increase the battery and motor size, pair it with the 2.7EB instead of the 3.5EB, and get a 30mpg truck. But I suspect they will move towards EREV (a la Scout Harvester and Dodge Ramcharger) rather than investing in a Powerboost 2.0.

Ford could have totally gone with the 2.7 hybrid and netted 30+ out of the F150. Personally I think it would have been better to have put in an axial flux motor that's easily capable of producing twice the power as what we have now at less than 1/2 the size. I mean look at what Lamborghini is using. a pair of YASA axial flux motors outputting 147 hp and 220lbs/ft each only 11" diameter x 3" thick. Absolutely amazing power for a motor pack the size of a large dinner plate. Ford could have used something with even 1/2 that rated power and coupled it with double the battery capacity and this would have been the perfect combination. Simply having the ability to accelerate moderately off the line on only EV mode with more throttle than a frog fart's amount of pedal without the ICE firing up every time to me would be a total game changer for the PB...

If we had an “infinite supply of electricity from the battery”, wouldn’t we have a fuel economy that is infinite?

Damned laws of thermal dynamics... ?

If only they had come up with a more appropriate name to describe it, other than EcoBoost..............like Powerboost

only after burning an infinite amount of fuel to charge it . . .

You all are too funny!

2021 Platinum Powerboost. Trans issues from the start. Mileage 18-19mpg. At 108xxx miles truck locked up partway into intersection. Towed in, hybrid module (motor) dead. $7650 repair.

Only true in some scenarios where you can keep the speed down so no ICE engagement is needed.

I meant more like effective infinite supply: aka if the battery capacity is large enough to cover daily needs and it gets recharged nightly.
