So I've narrowed down my search to either just going with the OEM charge tank, or going with 3 TC chargers. I read that TC is pretty much the same as the diginows (without some proprietary bits diginow retained.) Are the dimensions of the TCs the same? Is there enough room in the tank area, assuming I chop up the plastic insides of the tank, to mount 3 TC chargers like most people did with the diginows? I'm just wondering what most other people do with TC chargers, and I'd like to avoid taking off the tank right now to get the dimensions if other people have already done this.

If you're going to put them in the tank area and lose the storage, might I suggest just getting the Charge Tank by zero?

I'd also only run 2, because the 3rd means a second J connector.

You generally can't run all 3 from one J 1772. You can do all 3 from a Tesla destination charger with a Tesla tap, but otherwise you'll have to find a double J.

So just run 2. And put them in some side luggage.

That's my take.

But yes you could MAYBE stuff 3 in the tank area. The fans on the TC are different than how DigiNow configured them - so that could pose an issue.

Basically after all that customizing you might as well just have done an OEM charge tank.

I ended up with DigiNow because I am going to run them in a belly pan which keeps the tank area untouched - and I can then either get the power tank or just keep using it for storage.

Fitting 3 in the tank? Ha! Easy.

Hey Killertofu,

Here's what I did with 2 TC Chargers. I can recommend it, but I only fitted two. https://www.electricmotorcycleforum.com/boards/index.php?topic=11042.msg102950#msg102950

@MVetter this is very cool! How did you manage the cooling? My setup required powerful fans and that's only 2 and they're not used inside the bike, but taken out to charge. Great work, a bit chaotic;) but I'm no stranger to that

good god what's going on there? That's a fire hazard!

[MVetter]

It was a bit of a fire hazard, yes. All that is disassembled now. This was a friend's bike who got creative with the wiring harness and accessories. See the giant blue switch? That has 3 manual settings to redirect current to various J1772 inlets strewn all over the bike. The large blue Anderson connector is coming from a pack tap, aka a battery contactor override so you can charge >1C.

[DerKrawallkeks]

How much above 1C did he charge?
I like pushing the limits, but the max charge rate in the Farasis Cell datasheet is 1C, so that's maybe not too good for cycle life.

I'm curious what your friends experiences and thoughts were!

[MVetter]

the max charge rate in the Farasis Cell datasheet is 1C, so that's maybe not too good for cycle life.

Since when? The only reason they're 1C on a Zero is because of the thermal potting. Farasis cells can handle up to 4C; we've definitely pushed close to 3C before. Hell, my brother's FX routinely charges at 2C multiple times per day and he's got 30,000 miles on his batteries.

[Crissa]

Doesn't Farasis do the potting?

-Crissa

[DerKrawallkeks]

@MVetter it's in the Farasis cell datasheet, as I said in my previous post. You can find it by looking for "Farasis cell datasheet".
Where do you have the information from that the cells can handle up to 4C of charge current?

Is it possible to run extra chargers with the charge tank installed? I'm not sure how many accessory ports the charge tank takes up.

Sure. As long as you can get to the battery contacts of the motor controller and run you own wires as I did.


I can use my Elcons and DeltaQs at the same time and charge up to 12 KW, but I have only charged as high as ten KW so far, on my 2017 SR. The charge tank shouldn't change any of that, but my SR has the Pwr tank.

I thought the external chargers plugged into the Anderson connector. I thought there were two of them on the bike

There is only one (just above the motor), unless you have the Y-cable and then you have two. Those are the 75 amp Andersons.


I added a couple of 50 amp Andersons to my bike, wired to the motor controller.


So I can use two  Elcons and my DeltaQs at the same time on either of my Zeros.

How do you access the battery terminals on the controller? I haven't disassembled the bike yet so I'm blind to all this.
