Here's a rough concept diagram, And here's my hopeful order of operations on things:
J1772 connects- Onboard charger/rectifiers energize
Onboard charger opens contacts
Both onboard and Rectifiers charge battery
rectifiers voltage limit is 112v total, Charges to ~90% soc
Onboard continues to 100%
or
Seperate C-13 connects- Just onboard charger energizes/charges
Here is a link to the data sheet of the V1000A's Id like to use
http://www.dz98.com/wjj-pdf/v2500a.pdfTime for questions, I'm barely a freshman Electrical engineer! First time playing with AC
J1772: Do i need authentication circuitry, or will a generic adapter work well enough for most chargers?
Separate C-13: How do i not make this a finger destroyer when a J1772 is connected, Is there an AC rated Y switch i can use?
Rectifiers: Will they actually do what I want them to do with no programming(other than setting max V) (giving 20a*2 continuously up to 112v, not damaging batteries)
Will they suffer damage as the onboard charger raises the voltage to 116? Should I add a low current cut off?
Onboard: Will this freak the hell out at the rectifiers charging alongside it?
Will it finish charging to 100% if the rectifiers are still outputting 112v?
ACC charge port: Do i need the 100k? resistor on the signal pins to keep contactors open, or is that job already done with the Onboard being energized?
Wiring: Should i add seperate breakers for each pigtail C-13 to each rectifier, or single one after the J-1772?
And any other cheap used rectifiers you would recommend different?
This would be a system permanently installed on the back of the bike, but easily removed with the only two connections being the bikes C-13 and anderson ACC port
Will probably make the case with Aluminum angle and sheet
