Design, Making Multitask Power Supply to Check Car's Electric Equipment

11/12/2017 9:55 AM

Hi, Bro!

I'm making project about "Design, Making multitask Power Supply to check car's electric equipment"

Could you give me some solutions for that project?

Many thanks,

Phuc

Define the requirements and purchase one.

If you don't know where to start, it will be a failed project.

if it's homework, ask the instructor for help.

A multitask power supply (program with Arduino) to test the operation of car's electric equipment!

On the car, there're many electric equipment and I need adapter to connect it with multitask power supply!

<...adapter to connect it with multitask power supply...> [#2] is different from <...Making multitask Power Supply to check car's electric equipment...> [#0].

See #1⇑, as there is insufficient information available to allow the forum to help.

Please do not withhold thread-specific information as, generally speaking, no reader here likes games of "20 Questions".

PWSlack!

I want to test electric engine actuator (or sensor...) of the passenger car (4-16 seat). Could you give me some advice?

A power supply does NOT TEST anything.

What is a Power Supply? - Definition from Techopedia

As I said, define the requirements! Until you know what this device is supposed to do, and can tell somebody else, you will never succeed.

No-one here is your "bro".

No-one here is your mate, either.

If anyone here gave you solutions, then it wouldn't be your project.

I am not looking for anyone here to be my "mate", I am also not hiding behind the banner of A.P. as you are.

Don't feed the trolls, they'll suck the brains right out of you, or argue with idiots because they'll drag you down to their level and beat you with experience.

I think there are some large language difficulties here because a power supply to test car electrical equipment is basically a 12V power supply.

Without a more detailed explanation of what this tester is supposed to do and exactly what equipment it is testing (and to what degree) then all we can really do is guess (likely incorrectly), which really doesn't help anyone.

Also, we don't do homework here.

My advice would be think about what you want to test and what signals you need to generate and then have a look at Arduino literature online to figure out how to build and program the Arduino to perform these functions.

If you break it down into a series of simple steps it is much easier.

Thanks, Jack!

As you know there some equipment using different voltage on car like 5V from ECU, 12V from battery, a hundred of Volt for headlamp, or 7V, 9V for some equipment

I want to make a device to test equipment (without using the multimeter...)

Well if this is the project requirement then I would suggest building a single 0-100V DC variable power supply controlled by the Arduino. Alternatively you could build multiple individual set voltage power supplies.

A single power supply is best though, and there are plenty of designs online using either dedicated power supply modules, control chips and a few discrete components or using entirely discrete components (depending on how complex you need to make the design.

What is the project for, is this for school, college, University, PhD program, etc? Level of complexity will scale depending on what technical level you are at.

If its a simple mechanical position sensor then a multimeter resistance or continuity test can be used to test it. If it is a more complicated electronic sensor you would need to do some research into how the sensor operates to decide what signals you need to simulate and how to monitor the sensor is operating.

Here is a linear supply:

https://www.digikey.com/product-detail/en/texas-instruments/LM2931CS-NOPB/LM2931CS-NOPB-ND/363861

Input voltage is 26VDC (Max) with variable output of 3VDC to 24VDC.

Datasheet is here.
