battery monitor

[aznw82]

Hi all,

I need to write a battery monitor program in labview that communicates with a CanBus connection.

Is there any examples that i can use as a template? Do I need any driver & hardware for it??

Thanks,

If you have to communicate with a CAN device, you will need a CAN Interface of course. And, of course, this interface needs drivers.

So: What will the CAN Interface be?

If it is from NI, you will need NI CAN as driver. This driver installs examples for LV, so you will (hopefully) save developement time.

hope this helps,

the main interface is written by C and outputing thru the CanBus. The program im suppose to be writing is reading the Voltage & Current from that C program.

so, i should have NI Can as a driver and use the examples for the readings.

anyone that has those types of examples?

what kind of NI can interface hardware do i need to have? how does it communicates with the CanBus?

Depending on the CAN, you will need a CAN lowspeed or highspeed interface. There are devices with one or two ports available. Feel free to browse ni.com for CAN hardware and decide which could work with your CAN bus. You can always ask your local NI sales rep if you are unsure.

If you install NI CAN, examples for basic IO are installed too. So it is only the task to find the appropriate example for your task.

hope this helps,

ok, i'll do that. thanks for the help

does anyone have a template for the simulating battery life???can't find any in the examples.

Hi anzw82,

what do you need? Do you need a real simulation from charged to empty? What about loads?

Can you explain a bit more?

yes, i need a simulator from charge to empty. this is what i got for my numbers.

amp: 500

volt: 28.80

load: .0576

power:14400

those numbers needs to send out when application is running.
