Hello again everyone,
I'm still bothering you because a new idea has been on my mind for a while now. I thought I saw that several projects of this type are developing.
Quickly:
* A generator generating 800 watt / 220 volts on a continuous basis consuming 0.7 liters per hour.
* A set of battery (let's take 40 ah and 36 volts) supplying a motor with 36 volts and 1 kw => current = 28 amps.
Currently we have (apart from losses) 1h25 of autonomy at full power.
Now add a 36 volt charger charging the batteries. The output amperage is 22 amps.
So I have a 40 A tank to which every hour I take 28 amps and I give 22 A.
Several hypotheses emerge:
1) I start with a full battery and the generator runs continuously. I therefore empty the battery of 6 amps per hour on 40 amperes of tank ==> 6.6 h of autonomy with a gasoline consumption of 700 ml.
2) I switch on my engine for half an hour every hour. So I empty my tank of 28 amperes per hour and I add 11
=> loss of 17 amperes.
So I arrive at 2 a.m. and a bit of autonomy
with 350 ml of consumption per hour
Of course, this model is in perfect cycle without taking into account all the losses (coulon, mechanical, ....). I think a factor of 0.8 is what is used in electric motors.
Always the same question: viable or not?
Electrothermal hybrid
Technically, the thermal hybrid is only reasonable with a permanent magnet generator to charge the batteries directly ... therefore a high-efficiency product close to 0.9 ... which does not exist commercially (except for Polar USA), if you are very rich. or cheap if you make it yourself

I live in Belgium. Many buggy pgo type vehicles and their 1-seater Chinese version are approved. The papers circulate very easily and the blank plates are everywhere. All the more the mopeds have no technical control, all modifications are allowed. It is for this reason that we find dax with 3 wheels and other fantasies. I have 1 frame with the plate on it.

Obviously, in a free country, it's simpler.
To make your group, Kelly 5 Kw motor + 5 Kw controller = 850 $
Total efficiency 85 to 90%, programmable and replaces the starter
A tri diode bridge can replace the controller, so just $ 450 for the elect motor, but provide an overload prevention that cuts the group and a rope to start

2CV or 1.5Kw
You can look for an engine of only 1.5 Kw cheaper, that is enough in effect, but the smaller it is and used at the nominal power ... the less it is reliable.

Voila, in fact I just thought about it with a friend and we compared the consumption of the generator set found with that of a mower engine and the difference is not huge.
Is it possible to change the lens with a 24 volt propulsion motor. I would then get a 2.5 hp mower engine driving 2 car alternators.
In fact in all that leaves me most puzzled is the 1000 watt motor in 24 or 36 volt. Will it be able, with a variable reduction, to train the whole machine? There is for 40-50 kg empty ...
