measure percentage

I mean the SOC can not be displayed and can not measure the percentage of power left.

You need to be more specific.

Hi xuan,

 

use a probe to test the X value you're using to interpolate your points. (Using an ndicator might be a good idea too.)

What value do you feed to the Interpolate1DArray function?

Best regards,
GerdW

The value I feed is the voltage of battery. One voltage level  got a corresponding charge%. But now I can not get the charge%.

Move that indicator to the output of the index array and report back exactly what the indicator shows. I have no idea why you've ignored the advice about dealing with an array but you need to pay more attention to what people have said.

We cannot use array because we need further calculation. The values are not only 11 but more exact. Like 12.23V corresponding 62%...

Hi xuan,

 

I really don't know why this will not work for you:

The values are not only 11 but more exact. Like 12.23V corresponding 62%...

In my (simplified) example this also works nicely! You just need to wire things correctly…

I don't understand this. You can do calculations on arrays too…

Best regards,
