Subject: | Re: PASS-THROUGH CHARGER |
Alec,
WELL, I guess technically you are sort of correct. BUT!! Can the the
system/load run off the alternator with out the battery being connected?
You are saying the battery can do only one thing at a time. Not on my
plane, as I have an alternator that requires a Field Voltage. Remove the
battery and there is no field voltage.
Your explanation sounds like there is a switch that turns the battery on
and off.
Taking it in and out of the circuit.
To prove your point, connect an O Scope to the battery and just look for
spikes going all the way to ZERO. Ripple does not count, unless you want
to get drunk ;-D

Subject: | Re: PASS-THROUGH CHARGER |
Technically correct is the best kind of correct to be :-)
Any instant the battery terminal voltage is above (say) 12.5V, no current is being
withdrawn from the battery. During that time the alternator field is being
driven by the alternator, and not the battery. The battery might be doing some
smoothing effects, but its not providing any power, to anything, as long as
the engine is turning and the alternator is functioning.
I once had a mechanic explain to me that the battery powers the avionics, and the
alternator recharges the battery. This isnt so: For as long as the alternator
is working normally and the engine is running, the alternator powers the avionics
and keeps the battery topped up. Power is only withdrawn from the battery
when the alternator isnt functioning.

The answer is very simple:
The Charge Voltage and Current is MORE that the System Drain.
The charge voltage has to be 13.8 to 14.2/5 VDC.
The system on most planes is only 12 VDC (Battery Voltage) or LESS!
Yes, there are 24 V systems.
Your explanation is 99% correct, BUT! The battery is in PARALLEL with the load,
so as long as the supply is higher than the load the battery will charge. The
load will run off the Alternator via the ACU.

A battery is a two terminal device: either you are pushing current into it, in
which case youre charging it, or youre withdrawing current, in which case youre
using it.
If the terminal voltage is higher than the sum of the series cell voltages then
current will flow into the battery. If the terminal voltage is lower than the
sum of the cell voltages then current is being withdrawn. It cant be both at
the same time.

Correct. We're never simultaneously 'charging'
and 'discharging' the battery.
If you start you car with a heavily depleted
battery, a substantial portion of the alternator's
output will be dedicated to replacing the
battery's lost energy. AT THE SAME TIME,
the alternator picks up system loads in
the vehicle. So yes, the battery isn't
both charging and supplying energy to the
system loads.
In fact, during normal operations for
the configuration I proposed, the battery
would only be used to power the 5v system
loads while the engine is still off in
preflight. But as soon your chartger circuit
is supplied with power from as the ship's
the battery gets replenished and the 5v
system continues to function.
If the ship's main power is not available,
then the battery steps in to supply system
power

Subject: | Re: PASS-THROUGH CHARGER |
All electrical loads will draw current from the source with the highest voltage.
When the alternator is operating, its voltage is higher than the battery voltage.
Thus the alternator will be powering all loads. The battery could be
disconnected and the electrical system will continue to operate. However, the
battery does provide stabilization. When my PC680 battery failed open due to
a broken internal weld, everything kept working. But the voltage was unstable,
fluctuating up and down by a volt, if I remember right. That fluctuation set
off voltage alarms in my Dynon D-180.

You misunderstand. Many people use those little ready built battery
packs that you can use to recharge your phone on-the-go. Not all of
those can be charged at the same time they're in use. Here's one that
can be:
https://www.amazon.com/gp/product/B00MQSMEEE/
The original poster is using something like that and charging it at
home. As many suggested, a simple solution is simply to use a 12v USB
adapter to power the Stratux directly from the plane. But there was also
a comment about still wanting it to be on a battery. So one alternative
is to use the USB adapter to charge up the battery pack shown above and
power the Stratux from the battery.

Subject: | Question: can these wires be put in one wire bundle? |
I am currently working on a new panel for my Europa, part of which is the installation
of a new transponder and radio (Trig's TY91 and TT21). The remote units
of these will be put behind the seats under the baggage area, and I need to
bring a wire bundle forward to the panel.
My plan was to put all the wires for both units into a single wire bundle except
for the mic, phone and ptt wires. In addition I plan of putting a single power
and ground wire into this bundle, connecting to a separate fuseblock near
the units in the back (of course, the AWG of these will be scaled upwards appropriately).
My question: can this be done without problems like creating EM coupling, crosstalk,
etc.?
I will also need to put two shielded audio cables back to front to connect into
the AP60 audio mixer that is also in the back near the radio/xpdr units. I guess
it's best to keep those separate from this bundle, but as these audio wries
will be running sort of parallel to mentioned wire bundle what is the minimum
distance between these two runs to avoid audio issues? Also: if my guess of
keeping the audio wires separate is wrong, please let me know.

Keep the Transponder COAX out of the bundle. Run it as far away from ALL

Hi Rick:
I am the original poster and also the same guy that wants to have the
battery connected and charging (as required) with the RPi & Stratux. The
other thing I wish to do is NOT use a standard 5 VDC battery pack but use
a 12 VDC @ 12 AH battery.
Thanks to WERNER, and his idea of using a DC to DC Converter the project
now has a Solution.
The project will:
1 - Run off the plane's power.
2 - Have a separate Power Source - 12 VDC battery
3 - Have an output of 5.2 VDC @ 3 Amps to run the RPi.
Oh! Side note: Remember "Strike Finders"?
Well, RPi now has a version of Strike Finder which is told to be more
accurate and more sensitive.
SO... My project will have more than enough power to run a second RPi.

You misunderstand. Many people use those little ready built battery packs that
you can use to recharge your phone on-the-go. Not all of those can be charged
at the same time they're in use. Here's one that can be:

The original poster is using something like that and charging it at home. As many
suggested, a simple solution is simply to use a 12v USB adapter to power the
Stratux directly from the plane. But there was also a comment about still wanting
it to be on a battery. So one alternative is to use the USB adapter to charge
up the battery pack shown above and power the Stratux from the battery.

what the consensus was, now, but that's another option to look for. That said,
I, like the other folks here, just have mine plugged into a USB power supply
connected to my avionics bus. Haven't had any issues with file system corruption
yet.
