Re: Old BMS Hardware Thread

Eih Peter,

One more thing,

In master, why do you use Charger Relay and Charger Cutback?

Thank you.

Regards,

Francisco.

Re: Old BMS Hardware Thread

I took a look at the master schematic. You use a 4-way, but only use 3 pin way out, right?

One for vcc, one for gnd and one for out, right?

Thank you very much,

Francisco.

Re: Old BMS Hardware Thread

this is a 5-pin current sensor, how you connect it, since you have a schematic of master with 4-pin way?

Thank you.

Francisco.

Re: Old BMS Hardware Thread

Hi again.

Hey Peter, what is the current sensor you use?

Regards,

Re: Old BMS Software Thread

Hi Peter. Are you there?

What you say about my last comment?

About the function of RefADC?

Greetings.

Re: Old BMS Software Thread

oh I see.

I thought it was because you have 100V of rated voltage.

But if it is for that reason, that is Ok.

It's 16 bits, 2^16=65535.

Regards,

Francisco.

Re: Old BMS Software Thread

Hi all.

In slave program you use one equation that I don't understand.

RefVADC=63200 - (1.235x1023x100/2=63200)

Why 100/2?

Best Regards,

Francisco.

Re: Old BMS Hardware Thread

Ok Peter.

I have to make a few changes.

Just one more thing.

Where do you connect pin 2 of PIC, so it can make Slave Alive Toggle Test Ouput?

Regards,

Francisco Mendes.

Re: Old BMS Hardware Thread

Hi all. I've been busy last month. I already have started in the program of PIC's, as I made a few changes and I'm doing it in C language. When I'm done with it, I'll post everything here. Now I have one doupt. Peter, can you tell me if I have the right schematic of digital slave? Is the right versi...

Re: Old BMS Software Thread

Greg thank you very much. I was not understanding few things but now it's everything clear for me. I thought it wasn't needed to remove pic from board, but since we need to do it, i'm going to build the circuit to program the pic on-board. I made a few changes on my schematic, since I don't need few...
