If I buy an external charger from Zero for my FX, so I can charge batteries off the bike (motel room, etc.) am I going to have to handle two separate chargers? Or does Zero repackage two series connected chargers into one case?

BTW - Almost makes me wish I still had my switchmode DC power supply company. We would probably be manufacturing EV chargers by now. As it was we were making big SLA chargers and charge controllers for the telecom industry. Well, actually I'm glad I'm retired and can afford to buy a charger, and have the time to ride.

I don't know if it's possible to remove the onboard charger. I suspect it's a non-trivial task, but you probably have the right skillset for it : )

As I suspected, I wasn't able to get back to the bike before it got to 100% on the level 2 charger, but when I plugged it in at 64% it was reading 24 amps charging.

The level 2 charge rate is listed as twice the level 1 charge rate, but if it is taking double the amps at 240v, then shouldn't it charge at 4x the rate of the 120v/12A charger?  Or am I reading it wrong?  Or is the J1772 port able to tell the chargepoint charger to feed it 120v instead of 240v?  Or do they step the 240v down to 120v internally?  Ummm?

I have been plugging into Chargepoint dual L1/L2 chargers as seen towards the bottom of this page.  They do list 120v/16A, but I believe that is through their Nema 5-20 outlet and I've been using their J1772 plug which I'm guessing is the one spec'd at 208-240v/30A.

In theory J1772 can supply 120V AC but it typically supplies 240V AC.

Was the 24A supply-rate battery-side (DC) or wall-side (AC)?

Was the 24A supply-rate battery-side (DC) or wall-side (AC)?

It was dash-side. 

Not sure what it is reporting on the dash, but that's what it said.  The 12A matches what the included 110v wall charger supplies, but given that the battery pack voltage is listed as 103.6V then the two measurements would be very close so maybe it is a battery DC measurement...

[protomech]

Probably battery-side then.

90 Ah / 24A = ~3.8 hours bulk charge rate.

Hi flar,

sorry its off the topic but you are the first I realized riding a Brammo Empulse R

Would you like to write about your experience in the Brammo thread?

I still waiting that there is more "life" in this thread. I am not sure if they will make it to Europe in the next time, but it is always good to hear of real-live experience.
