So I noticed a fourth generation of TC charger is coming to market, and they did the one thing we needed--made them thinner!

Unfortunately mounting it is still very weird (why are the feet TOWARDS the fans), and also unfortunately they chose to make the 3.3kW unit more square instead of longer (which would have helped for pan replacement). At least the watercooling built-in option looks pretty slick.

hk-j (what we know and love) 222x109x125
hk-l (6.6) 270x230x110 air or water
hk-m (3.3) 198x244x95

I found an unfinished-looking datasheet for the HK-L which gave better measurements (attached). It looks like it is even smaller than their measurement of extents:

Edit:  Whoops, maybe not thinner, it appears these measurements may or may not include heatsinks and fans, even on the HK-J. I'll go measure mine and compare to the engineering drawings.

Edit:  Apparently, these were made in 2017 so is this old news? I'm struggling now to see the benefit of these. Maybe they weigh less or have better cooling...

Mounting tabs on the "top" are to mate with standoffs from the "bottom" on assembly line perhaps also for shock absorbing mounts. I would like to see real photos of these devices (yes especially water-cooled). I'm not so sure about those rendered images. The electrical connectors look wrong to me at a glance (180degree rotate? exactly what a lazy 3D artist does to be quick). Images on the English version pages don't match the default Chinese language webpages:

TC Charger 4th Generation 3.3KW HK-M Series OBC
TC Charger 4th Generation 3.3KW HK-M Series OBC (archive in Wayback machine)

TC Charger 4th Generation 6.6KW HK-L Series OBC
TC Charger 4th Generation 6.6KW HK-L Series OBC (archive in Wayback machine)

...

The 4th gen combination units that add DC/DC conversion seem to be stacked together with the new re-designed castings; again I don't really trust those renderings.

Those aren't renders, and the images are identical in both of the links you've posted as well as what Talon posted. Don't really see what the issue with the connectors is, cables twist.

My old HK-J 3.3kW can push 32A and the max voltage is 132V
The HK-M 3.3kW can push 23A and the max voltage is 198V (I guess from here, since I don't read the Chinese)

If it is really the case, the old version should be better for my 116V battery pack.

The old HK-J was offered in many versions, some that could do lower voltage and higher current, and some that would go higher.. I imagine you are looking at just one version of the new one. I saw a new one with comparable voltage range for Zero that did up to 42A.. (of course that would be over 3.3kW) so these specs are all over the place even on their own unfinished website. Still seeing a lot of placeholder pages.

[gt13013]

In fact, there exists English pages:
http://www.tccharger.com/EN/product/13302.html for the 3rd Generation 3.3KW HK-J
http://www.tccharger.com/EN/product/13303.html for the 4th Generation 3.3KW HK-M
and I attach a side by side comparison

[NoMoreIdeas]

Thats exciting! But as gt13013 pointed out the one that would fit out bikes only puts out 23 amps. Maybe they will come out with one in a lower voltage spec that delivers more amps.

[Brian2000]

I wrote to Elcon to ask if they intend to sell the HK-L 6.6kw charger, and it turns out they already do! Knowing that I wanted to charge a Zero, they said I should get the HK-LF-108-60 model (which I didn't know existed). It took about 1 week to arrive, and I've been playing around with it to charge my FXS 7.2. For now I am just charging from a standard NA outlet at 10 amps + 5 amps of the onboard charger. Hopefully soon I'll receive a J1772 to C-13R+pigtail adapter from TucsonEV. I have the back rack ready to install too, so I'm pretty excited about having a huge boost in riding possibilities!

A few other things of note:
- It was $1500 + $27 shipping to Chicago. I couldn't find it anywhere else, and I wanted the smaller size and weight so I paid the premium.
- They said they only sell the CAN BUS version, not the charge enable version.
- I went with a Thunderstruck EVCC. I had to change the baud rate to 500kbps in order to receive anything from the HK-L. Otherwise it was easy to configure.
- The charger, cables, and case weigh 25 pounds combined.

[Brian2000]

This is just to show a bit more about what comes in the box for the HK-LF-108-60.

The 3-pole input cable is about 7 feet long, and the 2-pole output cable is about 4 feet long.

I forgot to follow up on this post, since it happened during one of my surgery recovery periods.

Excellent work with that setup. I've seen the chassis drawings but hadn't had reason to shift over from the HK-J.

25 lbs is a bit much to deal with onboard, even for 6.6kW, but offboard or in the SDS tank area, it's fine. The connectors and wiring look solid.

I don't even see these chargers on Elcon's product listing or manuals pages, nor knew to ask about them from Elcon.

I'll add this to my queue for the unofficial manual. Any details you can add would be welcome.

[gt13013]

@ Brian2000
I am using a similar setting, with a 3.3 kW TC charger and the Thunderstruck EVCC controler.
When I charge my FXS at about 4 kW, the pack temperature can increase.
When you will charge at more than 7 kW your 7.2 kWh pack, you should keep an eye on the pack temperature.

[Brian2000]

Thank you, gt13013, that's good info. I'll definitely monitor the temperature.

BrianTRice, here's a few other details that might be helpful about the HK-LF-108-60:

Dimensions
12x9.1x4.3 inches @ 16 pounds with no mounting brackets and no cables attached.
12x10.7x4.3 inches @ 16.6 pounds with mounting brackets and no cables attached.
When cables are attached, the length becomes about 14 inches instead of 12, which includes space for a little bend to the cabling if carrying in a hard case.

Power input is NEMA 6-20P to Amphenol HVSL633 063A106I with 11AWG wires.
Power output is Amphenol HVSL362 062A110I to bare end with 10mm^2 wires.
CAN BUS power is labeled 14V 60W with 20AWG wires.
CAN BUS signal is 22AWG wires and includes a resistor across the lines (appears to be 110ohm±10%).

[gt13013]

CAN BUS signal is 22AWG wires and includes a resistor across the lines (appears to be 110ohm±10%).

According to CAN specifications, the recommended value for the resistor is 120 ohms.
There should be one such resistor at each end of the CAN line. In our case, this line is simply made with the charger and the EVCC controller. Since the EVCC controller includes an internal resistor, I have added one 120 ohm resistor near the charger.
Attached pictures:
- screen capture of the EVCC controller documentation
- on this link, pictures 3 and 6 show the resistor that I have added

My old HK-J 3.3kW can push 32A and the max voltage is 132V
The HK-M 3.3kW can push 23A and the max voltage is 198V (I guess from here, since I don't read the Chinese)

If it is really the case, the old version should be better for my 116V battery pack.

I see this is an old thread, but here are the specs translated:

Basic parameters:
Input voltage range: AC90V~264V
Frequency range: 45Hz~65Hz
Power factor: ?0.99
Full load efficiency: ?93%
Mechanical shock and seismic class: QC/T 895?2011
Protection level: IP67
Working temperature: -40?? 85 ?
storage temperature: - 40 ? ~ 105 ?
charging control: cAN bus control or control enable line
size: 198 (length) x 244 (width) x 95 (H) (air)
protection: output overvoltage , overcurrent, short circuit, reverse polarity protection, input undervoltage and overvoltage protection, over-temperature protection
cooling: air, water.


Water cooled EV chargers. Looks like that would be easy to do in some bikes such as my Energica that already has a coolant tank. Perhaps they can squeeze in a  water cooled 6 KW AC charger in their 2022 models.

Hello Brian2000,

did you maybe have a chance to take a look at the temperature readings of the battery during charging with the external charger?

I am curious if it is possible to charge at those nearly 1C rates between rides on the go.

regards
