Re: ULtra Compact 1800W charger + Eltek programming

Is this the right thread for 2000W Flatpack2 HE programming as well? I am familiar with basics of C++/Arduino programming, but know very little about communication protocols. I can whip together libraries and expand on basic preliminary sketches though. I'm just trying to get up to speed on what pe...

Re: ULtra Compact 1800W charger

Hello, I have tried remmie1972's code with a Leonardo Can Bus, but I get the following answer from the rectifier: Received : 05014400 06 12 71 00 40 81 00 00 Serial Number is : 061271004081 TRANSMIT : 05004804 06 12 71 00 40 81 00 00 Log in with SrNr : 061271004081 Received : 05000081 3C 06 12 71 0...

Re: ULtra Compact 1800W charger

Try a delay(100); right before the line with
unsigned char login[8] = {0x06, 0x16, 0x71, 0x01, 0x49, 0x29, 0x00, 0x00}; //this is for logging into yo

This gives the can shield a little extra time to initialize.

Re: ULtra Compact 1800W charger

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 unit is 123456789012 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 th...

Re: ULtra Compact 1800W charger

I need help to long in to flatpack 2 .

This might have to do that...

this any ideas ?

Thanks for the help !
For 60 seconds walkin instead of 5 seconds use : CAN.sendMsgBuf(0x05004805, 1, 8, login);
when loging in (4805 insted of 4804)

Re: ULtra Compact 1800W charger

I've gotten the Leonardo CANBUS board board in the mail today. It's nice and small and the connectors are packaged seperately like they say on the website. Very Flatpackfriendly :D This is how to connect it to the flatpack : 1. solder a twisted pair to the CANL and CANH solder pads on the right side...

Re: ULtra Compact 1800W charger

Good news ! I can confirm that just sending the 2 messages from the previous post every few seconds is enough to keep the rectifier logged in and keeping the set current limit. I started with 2 seconds interval which worked fine. 10 second intervals were also fine. 15 seconds proved to be too long :...

This is so awesome Remmie, What surprised me about this is that you ACTUALLY SET A CURRENT LIMIT. I fiugred you conctrolled it through the code. Yes, that's indeed very handy and works pretty good. I'll try to see if I can change the code to just send the 2 commands for logging in and current contr...

Some more info about the Flatpack communication protocol. This works for both a Flatpack 2 HE and a Flatpack S 0x05014400 During walk-in (the period where the voltage builds up slowly) the rectifier periodically (every 10 seconds or so) sends out the following message when it's not logged in : 05014...

Re: ULtra Compact 1800W charger

400 CAD$ is about 275 euros so Eltek Germany is rippping me off :twisted:

275 euro's is a price I would consider reasonable for such a small but powerfull charger.

Re: ULtra Compact 1800W charger

CONFIRMED. This also works on a Flatpack S rectifier. Default voltage set to 57.6 Volt (highest it is capable of) and it does go into constant current mode. Tested this with 4 pcs 12V 12Ah leadgell batteries in series. Great work Planetaire !! By the way you can also use header 05 00 9C 00 data leng...

Re: ULtra Compact 1800W charger

Hi Setting a voltage higher than 57.6 results in a voltage of 57.6 so no luck if youvwould want to use it for anything higher. Same goes for lower than 43.5 . It just outputs 43.5 [quote] // 00 10 should be 40.96 returned is 43.8 measured is 44.0 // 00 11 should be 43.52 returned is 43.7 measured is...

These can be programmed for 58Vdc witch wold be awsome for the Zero motorcycle battery of 116V. That would only require 2 of these in serie to put 3600W in a very ultr...

Well, I had some success connecting to the Flatpack S Of the middle port (with the 4 tabs on the top) the 2 tabs on the top right of that port are for the CAN-bus (not RS485!)
