Battery Pack simulation on Matlab

moi8765 — Fri, 08 May 2020 14:44:22 GMT

I am trying to simulate a battery pack gfor an electric vehicle. I have made the basic model on simulink and have also made provisions for thermal analysis. The problem is that I do not have any data on SoC vs temperature, IR vs temperature and so on. The datasets I found online are indecipherable. Can someone please help me get some data?

Corvid-19 Question Challenge

clem57 — Wed, 22 Apr 2020 15:00:23 GMT

This was a question on an interview (not mine thank you). It goes like this:

You are given a random function returning a value from 0 to 1. Using that find the value of π .

I will wait a few days to see what happens. Please do not voluntarily give an answer right away. But hints are allowed.

"...but I'm stumped when it comes to 19 crows..."

How about Coleoptera-53 instead ?

Coleoptera being beetle

VW Beetle 53 being 'Herbie'

Herbie goes to ' xxxxx - xxxxx '

(although I guess 'Bananas' could also be appropriate here)

I'm not sure how we're supposed to give a reasonable explanation of what we're thinking without saying too much. I believe I was thinking along the same lines as neuromodulator. You could also describe it as involving 2 squares (the mathematical operation, not the shape).

Anyway, I know that rhyme about magpies but I'm stumped when it comes to 19 crows.

Btw, this is a stay at home challenge. dougw has hit the other based on a series. Fantastic.

Collectively, the answer is at hand. Actually there is more than one answer. The choices does demonstrate your mind processes. neuromodulator has hit the trigometeric one. Good job!

It is a bit tough to give a hint without giving it away, but if it is the method I'm thinking of it will take a very large number of random numbers to achieve 6 significant digits of precision.

Ohhh, you want us to guess! Well here is a hint of one method: it is based on the ratio between the area of a square and circle.

You could do this with any kind of random distribution actually, remember that distributions can be mapped to other distributions.

Presumably to occupy your mind while isolated...

RE: Corvid-19 Question Challenge

beacon_dave — Wed, 22 Apr 2020 21:54:10 GMT

That helps, but I was thinking more of the probability aspect if you vary the number of points generated between one and infinity...

Clem can you give a context of what you are trying to do?

What does this have to do with covid or corvids?

RE: Corvid-19 Question Challenge

clem57 — Wed, 22 Apr 2020 21:08:38 GMT

It is a uniform random function.

This is probably where the maths teacher would mark you down for not including the term 'estimate' or 'approximate'

You want us to give you hints so that you can find the answer?

I tried what you said. That's true and it's bug! anyone can help?

pwm block in simulink support package raspberry pi

parvaz — Fri, 25 May 2018 10:51:16 GMT

Hi everyone. I have a problem when I used PWM block of Raspberry PI support package. when I run Simulink model in the external mode that contains PWM block, time going to be slow and operation are not real-time. How can I fix that? you can see this problem with the easy example is like below:

Ladies and gentlemen

After greetings

I am looking for somebody can help me in my assignment which is MATLAB simulink in power system

I will attach to you my basic circuit and I want to stimulate this circuit

The purpose of this simulation processes is to show voltage, current and power factor before and after statcome and the affects of this statcom

Thank you for your help

How to get an integral image from the segmented image?

RE: matlab coding

michaelkellett — Sat, 01 Oct 2016 08:07:44 GMT

MATLAB has an extensive on line help system and Mathworks Central offers a huge range of advice and free downloads of useful code.

Take a look at them.

If you still can't solve the problem then break it up into little pieces, try and solve them and then come back with a specific question, with some context and explanation about what you are trying to do.
