Have you played with Arduinos at all? If not, I'd recommend getting one from someone reputable like Banggood (it'll run your bike, right?) and have a got at the tutorials in http://tronixstuff.com/tutorials/.
Thanks for the resources, I will order a couple to start tinkering. In the meanwhile I'll keep a close eye out on your prototype! I can't believe the prices of the components either. So the MOSFETs would be used for both the indicators and the fuse circuit? "

" I'll chime in quickly to say that I really haven't made much progress on this lately (or my El-Moto either) I have taken on a much bigger project, and have been almost singlehandedly rebuilding a 130 year old farmhouse. We will have siding going on in the next couple of weeks, and our occupancy inspection is in 4 days. so soon it will be buttoned up, and I will have time to play again. I am spending my rare spare minutes arranging some shop space for this winter.

That said, I would be thrilled if others took this and tried to improve. My plan was to open source this software, so input is welcome!. I like the FET boards too, I haven't seen those breakout boards before. I had looked at solid state relays breakout boards, but they can only handle 2A where the FETs will take 30. I suppose I should order a few to check them out. The first unit will be going in my ICE Cafe Racer this winter, I will update with progress on that when it happens.

" So I modded my Prius to get a tap into the hybrid battery. This gives me 200-250VDC, which the meanwells are content to accept. (Most switch-mode power supplies are) Although it can source 21kW peak, I can only take 3kW from the pack continuously because that's all the gas engine puts back into it when charging. I could potentially draw 4kW for a just a little while, with the battery making up the extra current, but that wouldn't last long with the Prius' 1.3kW pack. However, a friend who saw my project and happened to have some Prius batteries sitting around is going to give those to me- maybe I can add a second battery to my Prius for additional charging possibilities.

" Hi,

Can I get your attention and asking help for auto battery charge in my electric bike?

As the exposition appears, This auto battery charger circuit can be utilized to charge 12V and 6V batteries. On the off chance that it is utilized a transformer that can convey 4A to 5A at a voltage in the vicinity of 12.6V and 16V then we can dispose of the switch for 6V or 12V batteries. The schematic is given beneath.

It likewise gave some support tip about the auto battery.

The auto battery charging current is consequently constrained to 4.2A. On the off chance that there is a 600mV voltage on R1 (4A through it), at that point, the T1 transistor begins to direct. Inordinate charging current is stayed away from in light of the fact that the present estimation of T3's base is constrained. The distinction between connected load current (at T4's authority) and genuine voltage of the battery are adjusted through T4's gatherer producer intersection. According to the datasheet of 2N3055AG https://www.icrfq.com/part/1926205-2N3055AG.html

The power contribution of 2N3055AG is the result of load current and voltage distinction as of now said. While charging 6V auto battery this power achieves a greatest of 40W. The rectifier diodes must have the capacity to convey 4A at 40V. T4 2N3055 must be mounted on a decent heatsink keeping in mind the end goal to scatter the warmth.

I can't comprehend what byx21-40 is?

1) Is it like a diode rectifier ??
2)and what is 21-40 implies like between 21-40 or simply it's datasheet code (since I scarcely discovered it on google)
3)and if it's being sold similarly as it is and consider the possibility that I didn't discover it in the market.

Sorry for my poor English and asking too much question. "
