Buy Sell Trade / Eletek Breakout PCB
« on: September 04, 2020, 01:32:34 AM »
For any charger enthousiast/creators who want to charge via Elteks I have created these nice little breakout PCB's. Just put an header on it for the mains power, solder thick wires on the DC side and hook up any CANbus wires if needed and you're good to go.

Price €15/piece ex shipping

Pm me for questions on ELtek based charging and controlling via CANbus

Oh, and since 2017, the cells can do 4C continuous and 10C peak.

DIScharge the're talking about, not charging.. But still very good specs, and becourse the pouchcells have very low internal resistance they don't require addidional cooling. Wich is great and keeps the compexity of an EV low on the battery side.

If they want to sell more, make a better internet shop with all products and details.

Not email them, I want search, select, buy !
Diginow would also sell more, I'm sure.

True, I've emailed Hollywood Electrics in the past quite a few times about the Supercharger, but got little to no respons. Does Europe/other continent count?
Now I've  several emails out for the fairing. But no response. Not sure if it's America first? One start thinking these things when living not in America..

I'm sure there are enough people overseas who want to buy a fairing or chargers from Hollywood El. Oh boy, get a proper webshop up!

[edit: promt got a reply via mail :o ]

Meanwhile both Quad packs are sold to happy Zero riders. One is sltill living in Holland and one has gone abroad to Zwitserland. Thanks everyone for the interest you showed, questions asked and pm's!

Placed also this call in the garage/homebrew section..

I'm looking for people who are interested in a Quad Eltek FlatPack charger, I'm happy to build one for you!

Home Brew / Custom Eltek Quad charger 8500W
« on: February 27, 2018, 08:05:45 PM »
Hi all,

Just becourse I can put my hands on another 8 of these power hungry, super small, high efficiency FlatPacks I want to investigate if I can make two European Zero owners very happy with another set of my custom build FlatPack based Quad Super Chargers solution.

Are you traveling long distances and want to recharge fast? Than this is probably an affordable charging solution €/w.

I build several of these config's last year and customers are very happy with it still. A few in Holland and a few in Germany right now.

The chargers are fully operational and tested when delivered. They will come with a 3 Phase Type-2 plug, a brown Anderson plug and a C13 cable for the onboard.

Phase's:
Ph1: Onboard
Ph2: 2 x FP1800 48V
Ph3: 2 x FP1800 48V

Total power 1300 + 7200 = 8500W  8)

Dimensions are (hxbxd) 9,3x14,5x28cm

Price is €2500 incl. shipping in Europe, invoices are possible.

Power draw is more than 16A on each phase, so 22kW chargingstations like the one's at FastNed are a must. If you try a 11kW station, it will disconnect after 20 sec's..

Please mail me if you are interested or have questions.

Pics are attached..

On my previous DS2014 I wrapped all connections in heat-shrink after having trouble with wet connections. See pic below:

Great schematic! I try to read and understand all Opto’s and transistors you’re using..  For the keyless charge start, which I want to incorporate in my eltek charger, what code do I need in my arduino? Also the batt - and arduino gnd connections are interesting. Should be connected via a resistor?

Zero Motorcycles Forum | 2013+ / Re: Questions on FastCharging / DigiNow Supercharger
« on: November 12, 2017, 03:02:15 PM »
Just a queustion about the usage of the Diginow v2's. It's probably mentioned somewehere but I can't find it in the dayly growing bunch of posts  ;D

I was wondering if the Diginow is capable of closing the contactor by itself or does one need to key the bike on and once the charge is engaged the ignition keys can be removed?

And if it can close it by itself how is this being done? I'm asking this becourse I'm working on a Eltek charger setup and run into this issue. It would be so elegantely if a charger can activate the contactor by itself.

Oh, but thats really straight forward. Its all printed on the pcb.
Included are some screw terminals to connect/disconnect wires easy.

Haha, yes the Hobbytronics CAN interface is really cheap and works also great. Proffesional Interfaces are very expensive.

There's a how-to included in the Sketch. If you open the sketch with the Arduino program you will see the instructions on top of the file. You need to fill in the serial number and the desired voltage. I copy below the instructions wich is in the file:


// Eltek Flatpack Permanent Voltage changer, Code By RHO
// Used Arduino board is a Leonardo CANbus Board, abtainable at http://www.hobbytronics.co.uk

// The procedure for permanent default voltage change is :
// You have to have a connection to the CAN-bus (obviously)
// if the serial number of your Flatpack is 123456789012
// Change line 46 with the serial nr in the code as below
// send 0x05004804 0x12 0x34 0x56 0x78 0x90 0x12 0x00 0x00 (to log in to the rectifier)
// send 0x05009C02 0x2B 0x15 0x00 0x80 0x16 (to set the permanent default voltage)

// upload code to Arduino
// disconnect Arduino from usb so it powers down
// First power on the Flatpack
// Then power on Arduino via usb

// After about 10 seconds or so the output voltage should change to the new default voltage.
// Now wait 30 seconds and disconnect the power to the rectifier.

// When you start up again the voltage will default to (in this sketch ) 57.5 Volt. The default voltage is determined by the last 2 bytes of the second command.
// Multiply your desired voltage with 100 (57.50 => 5750).
// Convert this number to HEX values (5700 => 0x1680). switch the two bytes (0x1680 => 0x80 0x16) and you have your code for setting the voltage

// NOTE: Some Flatpacks needs to run this procedure several times to change the Voltage.
// Sometimes the Flatpack shows an yellow led, but no Voltage change. Just repeat the procedure until it changes the voltage.

I'm curious if you can change the voltage permanentely like I did this before with the help of Remmie on other Eltek Chargers.
All you need is a Arduino with CAN bus.
Here's the Arduino sketch and info:

All credits are for Remmie, who reversed engineerded this all. I just added some text so everybody can understand and use it.

Ha, Yes saw them a while ago on the Eltek site. I will stick with a couple of Eltek's 1800's in series due to the higher power rate vs formfactor though.

But maybe they can be programmed in the same way as a "normal" flatpack can be set to a different default Voltage level?

Looking at your burned plug it should be the top pole indeed. Don't scrape/file too much material away.. Then the contact pressure lowers and that isn't good too. If this all isn't helping, just replace the chassis part of the power inlet. It's no official Zero part but just an 2 dollar piece wich is being customised by Zero.

The part is actually this unit or similar:
http://tinkersphere.com/power/962-male-power-connector-iec-320-c13-c14.html
(try to get one without solderholes in the contacts..)

Put carefully new heatshrink back, so it is closed and kind of water/dust proof..
