    You still need a battery for stored starting amperage. The alternator with DC/DC converter would recharge the battery and run the ignition circuit and fan.

      Maybe not with the lipo battery. It'd need a balance charger and lipos can take hours to charge at sane charging rates and generally don't like discharge while doing so, so maybe not entirely practical yet.

      ​@@Maurice_Of_Wisdom why would that be?
      First, you can't really "charge while being used". You can only switch between charge and discharge. Lipos don't have a memory effect, like the old NiCd's you're probably thinking of, and don't care about partial charge cycles. A quality pack with good health also requires little to no balancing.
      Did you know, that in an RC Car, lipos see huge charging currents of multiple C each time you apply the brakes at high speeds? Many other devices like phones, laptops, off-grid Solar Battery systems, etc can also switch between charging and discharging, depending on load.
      It would probably be a good idea to fit a small BMS board to the battery to add safety against overcharging from the DIY Alternator and take care of any balancing needs, should some arise. Other than that, I don't see the problem.

      @@fabianrudzewski9027 what i mean is in a rc car you can't really make a self sufficient system that doesn't need charging with just adding a alternator like real cars do
      How does a real car work? The battery has enough power to give to the starter motor and ignition before the engine is running after the engine is started and spinning the alternator takes over then alternator has enough power to make sure the battery is topped off and can start the motor again later when the car is turned off aka a self sufficient system because you don't need to charge the battery every time you come home from work for example and your done with the car. A car will run till it has gas and that's that.
      Now the reason why i say li-po don't work like that like you said there is only charge and discharge there is no inbetween a lipo cannot work as a self sufficient system in a petrol or nitro rc car with starter motors ignition system and all that
      But imma be honest: (the reason why i say this is because i have not seen this done ever and i would love to know if it's possible with a lipo or actually possible at all andif so i would like to know how you would go about it)

      @@Maurice_Of_Wisdom there's no reason why you can't correctly size a generator for an RC Car. A BLDC Motor (which is what the cison alternator is) of this size can easily exceed 100w of power draw and you can expect similar output when operating as a generator. The cison one might be too weak for the average current draw of johnys car. It's only rated at 12V 1A.
      Where did you get the idea, that a Lithium Battery can't do anything between charging and discharging? A lithium battery can absolutely sit connected to a power supply at constant voltage and have no current flowing, that's literally part of their charging procedure. Constant current until their final charge voltage, then final charge voltage until current declines to a trickle or to zero. In short: CC/CV charging.
      Lithium batteries have a relation between the state of charge and voltage. If you connect a battery to a PSU that's set between it's upper and lower voltage limits, the battery charges/discharges until it's voltage matches the PSU's voltage and current stops flowing. From then on, the battery can sit connected to the PSU indefinitely. Use a Generator as the PSU and you've got your onboard electrical system.
      If you want to see some applications of Lithium starter batteries, look at MHEV Cars or light weight Motorcycle batteries (both my bikes have lithium batteries). In case of the latter, you can simply toss your lead battery and fit a lighter lithium one. No changes to the electrical system required

      Exactely, using a capacitor is going the right direction, but the capacitor needs to be charged and only acts as a power-extension. In theory, it would work, but the issue is with the starte the alternator doesnt produce enough power to make these 12V...maybe with a smaller capacitor it would work, it only needs to provide 12V for a second or two, but this big one takes a minute to charge...

      Disregarding voltage spikes causing issues you can full run a car without a battery, you just cant start it without one (or some other stored potential like a super cap bank). The fact that the alternator charges a battery means it's putting out enough power to run the car, and charge the battery. Voltage regulation can be an issue which could cause voltages spikes that things won't like, but a well designed charging system should be able to cope with it.

I think the voltage is correct but the current at start js far to low and likely needs to be at higher revs for a useful current so its better to run everything off 1 battery big enough to run all electronics and charge the battery off that tiny alternator

    This is looking awesome! Also, the alternator doesn't spin fast enough during starting to make enough power to run the ignition directly, so a large capacitor to store up energy until it reaches enough voltage to run the ignition and get the engine idling might work. In a full-size vehicle with none of the advanced electrical modern comforts beyond a basic ECU, it takes a constant 4 to 5 amps at 12.6 to 14.4 volts to maintain an idle, that is to say fuel pump, ECU, ignition and fuel injection. An amp can probably be subtracted for a carbureted engine, and another amp for a mechanical fuel pump, though perhaps another half amp for mechanical ignition, so a tiny alternator on a tiny engine likely needs to build up enough voltage to get the ignition started before it can run under its own power. Its kind of like a magneto system, it has to reach a certain RPM before the magneto is getting enough voltage to create a spark, and once that happens the engine starts to generate power until its self-sufficient.

    • @Pitstopcomponents
      @Pitstopcomponents Месяц назад

      You are right and wrong. A big capacitor is not goign to work. A old car... a really old car without a ECU only uses a battery for starting and for the Ignition coil. The starter is the main reason for a big battery... but the Ignition is a constant user... once the engine runs, the battery becomes useless since the alternator provides all the power required. But we talk about a battery, not a capacitor. A battery stores power for long times and can give the power off for a while, while a capacitor is something that cannot "hold" a charge, it needs power to get charged, and as soon as that power is gone, it will give its stored power away again... this means that for starting, you need a full capacitor charge, and if you are only providing a small amount of electricity, this means it will take ages to get that charge. His contraption works, but he needs to spin the engine for 1-2 minutes straight.... a battery on the other hand will provide that charge from the start... imagine your car battery being dead, and you need to charge it.... imagine charging your car battery by letting the engine crank with a second battery hooked to the starter... doesnt make sense right???

      Oh and by the way, mechanical Ignition needs less Volts, because it is just as simple as a electronical distributor ignition... instead of a hall-sensor, you get a small cam that opens and closes contacts that then transmit power to the distributor arm and then to the currently active cylinder.

    With the rectifier and cap in place, all you need is a regulator. A DC 2 DC (technically DC to AC to DC) convertor works on a slightly different principle that doesn't guarantee that you will get enough usable current, especially on startup. Regulators on the other hand usually offer better current flow capabilities, especially on startup. There are many to meet almost every need in terms of input/output voltage regulation as well as current handling capabilities.
    In electronics terms, it a basic regulated power supply.

    Restriction in the cooling system is not necessarily a bad thing. Coolant needs time to absorb heat. Why mechanics say to run a thermostat, even if it's gutted.

      @ ok why?......it's not a misconception its thermodynamic law. Because there is a 100 percent chance that at some point the flow will be too fast for the water to have enough time in the radiator to shed enough heat or in block absorbing heat. Most engines it's never going to be a problem because of the design characteristics.

      @@royb.1441 It's hard to explain for me in English, but I'll try. The coolant is just acts as a medium and is in constant motion. If you slow down this movement with lower flow rates you reduce the thermal flow, the efficiency of cooling. If given part of the coolant has more time to heat up the heat stays in engine and does not reach the radiator. More delta T -> better heat flow.

    You should add a BMS that lets you draw power from the battery, while there is nothing coming from the alternator, and when the motor is running, the BMS switches power sources to the alternator, leaving the battery isolated and charging

    Those dc to dc coverter don't have enough current to start the engine at low rpm. But good enough to recharge the battery, but when it up to idling speed, it should be able to sustain it even if you unplug the battery. Probably need batter DC regulator and higher power, you can try an actual car alternator regulator.

      It's 3.25 nm based on their claimed hp rating. I've got the same engine, in a 1/7th scale car that weighs 11.5 lbs, and without even having it fully tuned yet, it's just a donut machine at this point, so I'm inclined to believe the rating is somewhat accurate. It's vastly more powerful than my big block nitro or any 2/3s cars I've seen.
