More Wiring Diagrams

Well, there’s been more wiring diagram stuff going on since last night.  Turns out that I do have an ElCon charger (well…sort of.  Elcon chargers are a rebranded version of a charger that’s made by some unknown corporation.  Although mine doesn’t say elcon, that’s what it is).

In any case, the elcon chargers have a bms control cable, so there’s no reason to use the external AC high current relay to shut the charger off.

I checked it out and shorting the two “pigtail” wires (i have the two wire pigtail bms control wire version), allows the charger to work.

So this became v1.15:

v1.15

Then, i decided to change the diagram for the controller J1 and J2 wires to reflect a bit more how it’s actually laid out instead of listing each wire in order.

v1.16

So that’s where we are now.  Everything seems to be working!  Woohoo!

Wiring Diagrams

I’ve spent a lot of time pondering the wiring of the bike.  Originally, i was thinking about how the main traction pack wiring was going to work (how each of the sets of cells would hook up to each other), and came up with this:

First wiring diagram

However, once i started down this path, i started trying to figure out where more and more of the parts would go.  Mainly, i wanted to do this because although I’ve tinkered with some electrical appliances and whatnot, i’ve never worked with this much electricity in terms of voltage nor amperage.  So, i’ve got a healthy amount of fear (hopefully enough) about working with this stuff.  As i keep telling myself as i’m working around the batteries “this crap can kill you…so be careful”.

Seriously.

In any case, I drew some diagrams on paper, but it wasn’t working out very well.  So, around september, i started laying out all of the pieces of the project as best as i could in a drawing program.  The first “real” diagram is shown here:

v1.1: The first version of the "real" wiring diagram.

Every time i figured out a bit more, i’d update the diagram…

things are happening fast

hey there.

I know i don’t post much anymore.  Mainly it’s because whenver i get a free moment…and i do really mean any moment at all, i go out to the garage and work on the bike.

I recently have the electronics almost all mounted, and i decided to go with making plugs for most all of the connectors instead of using terminal strips.  This was probably overkill in a lot of ways, but so is the rest of the bike!  Also, the plugs let me put things in and take them out (which i tend to do a lot!)

I need to take some photos and process the many videos soon…
