CAN-BUS Datalogger for Vectrix

Is there something that is able to balance every single cell, when I use my scooter?
Have you ever feld something like that?

I guess:
-You have original GP lithium
-You have a bad cell, with low capacity, and you think it limits your range. Unless you check the 39 other cells, this is not true at all.
-You are tired of getting less range with your vectrix. This explains why you are buying the peak cable, ans searching for a special device to keep your battery alive.

Let's go straight:
No Bms will be able to compensate the lost capacity of a bad cell during the short time of your ride.
oh Yes,
You may be able to locate that bad cell, and you might be extremely lucky and have one single bad cell (quite improbable)
You may manage also to make somebody build a complex, autonomous electronic device to inject energy to it, when the dam bad cell's voltage shrinks.
However,
The smart way is to forget about GP original battery. These cells are really bad, they won't last long. Don't waste your money on strange devices. Go to the solution it works: Buy an upgrading battery kit to vectrix parts, with full warranty. If it is too expensive, try to find leaf cells from a savaged yards, and upgrade your vectrix with them.

The Gp may be recycled to solar application or something else less demanding.

You are a clairvoyant.....
My GP aren't swollen, but got 30.000km...
so 42Ah are compromised.
there's no one cell weak in particular, about 10 that drop down towards 2.40V before others
and not at the same time, yesterday was number 2, today is number 34, tomorrow will be number 18...
I know it because I have disassembled Vx1 six time, I need Peak CAN...

But I dont want to consider my batteries.
all you have written about "balance during discharging" and "GP weak" is correct, but
consider that when red light is on, your pack isn't empty, it means only that one single cell is near 2.40V
Most likely one cell is 2.40V and twenty others are 3.10V (with GP packs)
or one cell is 2.40V and twenty others are 2.90V (with good packs).
So, system that I've thinked, aim to bring all cells at 2.40V at the same time.
Obviously with little bit of tolerance
Have you understood now this improvement?
I think that it could be increase GP's range of more than 20%
and used good pack, of more than 10%
On new good pack gain is nothing.
if there and if it worked, would you buy a system like this?

ok, I'll change in:
system that I've thinked, aim to bring all cells at 2.70V (end of discharge) at the same time.
take 2.70 like voltage of end of discharge and read again my words.

Consider that my original Vectrix BMS, stop MC when one cell drop down 2.40V

Which chemistry have cells in your foto?

Consider that LiFePo4 cant burn or explode

Instead LiPo or Ion can

Seems you know it all, i wish you all the best.

I wish you could take a look into my Datalogger! It's unusable in my new bike. Please help.

Only works with mc 10nn firmware, you have 20nn mc firm in your new vectrix. Prensel knows better what is going on.

PS: prensel, what an amazing surprise! you also like cityel/miniel! Have you ever tried the twike?

Thanks for the answer... I wasn't aware of that firmware incompatibility...

Consider you battery dead.

What?
I can run 70km in 35A mode, 78km in 30A mode and 91km in 25A mode.
It's a bad pack, but not dead.
Next week I should have Peak wire, and situation will be clearer, I hope...

Cristiano, I admire your efforts to save your shrinking GP battery, but the cells are bad,the manufacture process was defective, the battery is damaged due to old/ bad firmware.
Ok they gave you 30.000 km, this is a miracle. But admit it, the pack is screwed, focus your time, efforts and money in getting leaf cells. Stay tunned on vectrixparts web, second gen of BMS will show up soon. i recommend you buy one of the new Bms system, the leaf boxs and pcb adapters.

Just curious, 35A=80km/h, 25A=60km/h?
When you receive the peak adapter, update to latest firmware ( check http://service.vectrixparts.com/topics/24-vx-1-lili-firmware-40s-life-battery/). You may have latest MC version, you may not update MC. If you want to monitor charge process, remember you cannot plug the laptop to AC plug if vectrix is plugued to same AC plug, or it will fry up.

I also read the following in the first post of the latest may 2012 software instructions thread:

"Do not have the Bike charger cable connected to a mains supply whilst the computer is connected to the bike even if the mains is switched off. (this applies to a mains powered computer. It is safe to have a battery powered computer connected whilst the bike is connected to the mains power)"

I was not sure whether this would be a problem with a mains powered laptop, so I asked Matteo Zordan from Vectrix Parts, "Have you ever experienced problems connecting mains powered laptops while the charger is actually charging?"

He replied, "Yes you can connect the bike to the laptop using this cable while charging, no issue at all, the can bus is fully isolated at the bike side."

My laptops are always plugged into the mains when I use them to regularly monitor the charge process, and I have never had a problem with any of the three laptops that I have used with the Peak canbus adapter on both of my Vectrixes.

Thanks a lot, R.
Understood...

35A=80km/h, 25A=60km/h dont you result it?
I mean amperes for keep constant speed.

Hi Paul,
I went to your website (reho.nl/Vectrix/) and linked through to box.com and the file is not there. (yet?)

Thanks,
Kevin

Yes, the new firmware us now there. Thank you.

Hello,

I am a new Member, just have my Vectrix Vx1 NimH for 3 days.

I would be interested in buying one Magig Box, is it still availible?

Thanks

Hello,
Ist the magicbox still availible?

Thanks

Hey Paul,

I just finished my conversion to 20Modules leaf gen2 i already contacted dugas for modifying the FW of the ESD to accept up to 170V and he alread helped me. I did 2 charges til now up to 167V and it is holding until now, but i dont know how long it will last that high voltage.
I was looking for the 6.6kw TC charger, for the future, or do you have a better suggestion? Beat would be to have type2 as well as standard 230socket availible.

Will your magic box then work like framugas FW with Parameter settings via brake levers? What is the actual price?

Thanks, regards Marius

Hello, Paul.
Nice to hear from you here in the thread again.
One of my Vectrix scooters, which is rebuilt with 18 Nissan Leaf modules and a fully firmware integrated Universal BMS from Vectrixparts, Runke charger has been running very well for more than a year now but that's not the point, I would like to rebuild a second scooter, also with Nissan Leaf cells but maybe with your Canbus interface, a TC-Charger and maybe any good working BMS. Would that be solvable, how best and which BMS to use. Will it work with the standard Vectrix firmware ? Thanks for your patience. I have already one of your boxes.

Greetings from Germany

Klaus

Hi prensel,

I'm quite interesting into getting the source code.
Is it available on github ?

Thanks.

Well, I have one more question, your box can control different chargers, i.e. the charging current, but can it also limit the charging current of lithium cells when the first cell has reached its maximum voltage during charging, so that no cell exceeds the given maximum voltage during charging ? For this it would have to work together with BMS/Balancing.
