I don't know how to read or write and considering how much these gliders will be "pasticciati" to make us stay all the batteries I have realized a 20:1 regardless of the efficiency of the orignal medium (which however will never be used since all the journey will be done with motor on motion from takeoff to landingAh, my coat of arms flew it. not bad but the 50s of memory effency seem optimistic
It would be like saying that going around with an explosive motor is safe because they use the cartridges to start the engines of the planes.but if the electric is so unreliable because never the planes when they have to restart a flight engine rely on a battery and an electric motor:
You can see that you have little experience, if you want me to make you a list.In my experience, I didn't see cells drop by, I saw doa, I saw infant mortality, and I saw cells give a lot of signals that only if completely ignored lead to catastrophic failure.
Trust me, when you have a heat at 115 °C, trust me he's dead.a thermal input that goes short is recognized by a minimally evolved bms like a sensor failure, not a difficult cell, especially the voltage of the cell does not show signs of anomaly, plus there is also to consider infrared photos transistors inside the package, also they are those that control the temperature of the cells, to detach a remote so correct solution to avoid dangers
excellent solution, but eye to the power of the remaining package and predict two bmi with the possibility to manage each package separately, energy exchanges between packages in parallel are to be taken with the springs.with two parallel packages, there would also be no need to reduce the power too much if one of the two was to cause problems.
Don't treat me the hybrid for what it's not, we're not talking about a simple "motor" to turn on in emergency.I think it's better to have a second lithium pack than a gasoline scooter that maybe doesn't start or a supercap counter that's good for a couple of blocks.

an account is a starter battery that has to work a few seconds every tot hours, an account and use the same technology all the time.
Yes, if you have any manual or particular case that you like to tell I think it can be useful for all those who follow the forum, sooner or later "I'm afraid" that with the batteries we will have to deal with all the more often.You can see that you have little experience, if you want me to make you a list.
115 without smoke I would say that you are the heat that went, but in a sunny August with the ultra-fast charging vehicle parked in the sun and a cell that rises to 65° when the others are on the 55° as it seems to you?Trust me, when you have a heat at 115 °C, trust me he's dead.
I'll tell you more, rethinking and seeing that the engine will probably be made up of two coupled units (a little like when they put 2 9-cylinder stars to make the 18-cylinder) I was thinking of powering each engine with its controller and its battery pack, so that I have complete redundancy of the whole chain from the battery to the propeller.excellent solution, but eye to the power of the remaining package and predict two bmi with the possibility to manage each package separately, energy exchanges between packages in parallel are to be taken with the springs.
In my opinion, as a weight/cost, supercondensers are not a solution applicable to this case, for that weight and that cost I prefer to carry behind other batteriesDon't treat me the hybrid for what it's not, we're not talking about a simple "motor" to turn on in emergency.
With the supercondensers I've seen making 2 mw benches, I swear you didn't need to make a couple of blocks.
I have seen things that you humans cannot imagine!:biggrin:

The problem is that, automating a risk assessment.115 without smoke I would say that you are the heat that went, but in a sunny August with the ultra-fast charging vehicle parked in the sun and a cell that rises to 65° when the others are on the 55° as it seems to you?
This is the right way, actually it would be a hybrid between two batteries.I'll tell you more, rethinking and seeing that the engine will probably be made up of two coupled units (a little like when they put 2 9-cylinder stars to make the 18-cylinder) I was thinking of powering each engine with its controller and its battery pack, so that I have complete redundancy of the whole chain from the battery to the propeller.
I pretend I didn't read! :smile:I tried to avoid them as much as I could, putroppo in some situations I found myself playful in parallel to 2 packages, but they were united once and never detached again and all the alarms of the 2 bms were put in or
the best solution today is to implement a power bupper, the system kers.In my opinion, as a weight/cost, supercondensers are not a solution applicable to this case, for that weight and that cost I prefer to carry behind other batteries
recounts, of burning packages off the bastions,I have seen things that you humans cannot imagine!
:biggrin:
It's not just automating the risk assessment, I think it makes a lot of parameter characterization and deviation detection.The problem is that, automating a risk assessment.
:d :d more than hybrid I would call it a monoely bimotor, hybrid I consider the systems that are not homogeneousThis is the right way, actually it would be a hybrid between two batteries.
The two bms were there, and the software was actually hardwired with a logical or , every alarm coming from a single bms (hv,lv,t) was propagated to those who had to manage those alarms. I honestly had no problem (the car that went to dakar was made like this, a pre-existing 11kwh rear package and an additional package put up for the 8kwh trip, paralleled and never more disjoined)I pretend I didn't read! :smile:
two bms and a dedicated sw, not impossible, indeed, but still to be taken with the springs.
the best solution if you have space and weight available, if every single kg must be used with the maximum energy density possible such a system does not give you energy density, at most increases the density of power , but in this case it does not serve anything since we are talking about maximum discharges from 3c (max 4 minutes) , even during emergenciesthe best solution today is to implement a power bupper, the system kers.
Then you're out!recounts, of burning packages off the bastions,
bms rays flashing in the dark near the gate can
:biggrin::biggrin:
I think in any case that it is the right way to go.:d :d more than hybrid I would call it a monoely bimotor, hybrid I consider the systems that are not homogeneous
Igenic paper effect!the best solution if you have space and weight available, if every single kg must be used with the maximum energy density possible such a system does not give you energy density, at most increases the density of power , but in this case it does not serve anything since we are talking about maximum discharges from 3c (max 4 minutes) , even during emergencies
Thank you but I prefer a banal nda :d , even if I have seen some calendar that maybe it was better to stay dry :dThen you're out!
: smile:
dry question...Igenic paper effect!
:smile:
a power buffer should not exceed 10% of total energy.dry question...
Knowing that you need 19kwh to go from one airport to another, would you rather fly on a plane with 2 20kwh batteries each or on one with a 20 battery and a pack of supercondensors weighing like the battery?
