Re: connections for? EcityP Smart S5-13 BMS

ecitypower told me to remove CF13 to CF0 if cells are not connected and they did send me 0Ohm resistors as a replacement in case I would want to reuse these inputs again... According to me this excercise could only make sense if the unused CFs are replaced with 0Ohm resistors in order to shorten/br...

Re: connections for? EcityP Smart S5-13 BMS

Hi, thank you for the updates, it's very interesting. It's a bit sad that one fet was defective on each board... Btw, I guess that they tell you to remove the cap because it could couple some AC voltage to the unused cell pin, making it sense a cell and go crazy.

Re: connections for? EcityP Smart S5-13 BMS

Hi guys, sorry for the delay. Here is the software, but I can't find the "clean" DS anymore, so if someone can post it for me it would be great. I will look into it this weekend if needed, as I'm currently out of free time. :(
Bye

Re: connections for? EcityP Smart S5-13 BMS

Probably it's only the I2C part of the OZ that is "disabled" at power on. The OZ can work in I2C or in standalone mode, so maybe it starts with the latter by default. I have the DS but it's signed, if you know a way to remove text in bulk from the pdf pages I can upload it here, else just ask me for...

Hello all. Does anyboby here tried this software ? I got a BMS wich uses the OZ890 chip and I'm trying to see its configuration by reading the EEPROM.

Re: connections for? EcityP Smart S5-13 BMS

You can find all the register mappings in the files inside "C:\Program files\O2Micro\CowBoy\Configurations\". Look at scan.cfg:
#define "Cell1 (mV)" 0x00 0x0103 [0,1,2;0x32,5,3|0x33,8,0;(0);(0)] "" d
...
#define "Cell13 (mV)" 0x0c 0x0103 [0,1,2;0x4A,5,3|0x4B,8,0;(0);(0)] "" d

Re: connections for? EcityP Smart S5-13 BMS

Hi, I have 2 of these BMS too. I got my hands on the programmer, with all the i2c parameters addresses. I2c should be on pins 3 and 5 of the 12-pin connector on the edge of the board. I don't have a lot of time to experiment, so if you want it just pm me. you can communicate with the program via a s...

Well, if you don't know what to do of the prototypes and want to dump them at a lower price, count me in! I can rewire hall sensors by myself and fix minor issues, also I don't mind purple! ;)

Re: 12 kw rc motor

Here's another cheap dyno idea. Get an old exercycle with a friction brake. Use a known hp motor to determine the amount of friction braking at each adjustment. You could calculate the load with electrical measurements from the motor, temps, determine rpm. Not super accurate but should work ok. The...

The shaded background face is a bit creepy once you notice it... Well, I'm really curious about this motor and I think I'll order one when it will be available. Don't make us wait too long!! :D

As a side note, what controller are you guys going to use?

after getting mine, I think that I will try to sell the nicd batteries. They usually cost a lot, so selling them will give me some room to buy a nice TS pack.
