I don't understand which rule you refer to, can you post some more detail here which rule you mean and how you place fuses, please? Maybe I just don't understand the words...

On component weights...

I would not call myself an expert on this either, my experience is more with batteries than with inverters and motors, but here's some thoughts...

Battery:
From a cell perspective a higher...

Shivani,

what´s that picture about? It does not make any sense to me, from what I can see at given resolution...

In general, what I believe you describe, is, to my understanding, rules legal...

GTS,

I did not mean to offend you. I tried to imply, that I feel, that the thread is off topic. I understand now, we got a different perspective on DE in FSAE. It actually was my favorite event,...

GTS,

my post was actually about the DE, not about FSAE as a project. I was trying to circle Julian´s post back to DE and how you can judge a design process as long as students and judges are on...

I completely agree with Julian.


It seems like there is disagreement about the scoring formulas representing what a "weekend racer" would like. I agree that this is likely not the case, I do not...

Thanks for the hint. However, in that case I do (again) not understand what you need a throttle for on an electric car..? Where do you plan to put the sensor? On the pedal then, as a torque pedal...

So, this is for a Hybrid, not an electric car? A hybrid car which got a full size electric powertrain (so you call it an electric car) and electronic throttle control?

A throttle sensor is just a...

What are the requirements for a throttle sensor on an electric SAE car?

Correct. Tmax is Tmin*1.33



I personally do not think the effect you describe is very relevant. FSAE cars are too small and 5% energy is maybe 2.5 kg less on cells (if it was that easy to...

Hello,



Just to throw it out there... Looking at the numbers with just two questions in mind:
1: What top speed is desired and what does that mean for maximum gear ratio?
2: How much torque...

Hello Everyone,

I am involved in FSAE electric in the fifth season now, the first two being my active time working on electric powertrain development. Since I graduated, I work in automotive...

Sharan,

below some thoughts from me about your questions / rule EV3.3.3. As you are not very specific in your post, please do not automatically assume my thoughts are applicable to your system.
...

Sharan,

this is clearly defined by the rules, you should read them some more times!
In this case, you have to look for the word "OR" in rule EV4.12.1 and you will find out that the contactors can...

Hello Bharadwaz,

your question misses some detail, but I guess you´re talking about an EV and the required shutdown circuit..? A small circuit diagram would be helpful to understand what you got...

Hi,

why do you want to use a relay for this? As I understand, you want to pull 5V25_ISO to PACK-, controlled isolated from LV side to turn on the DCDC with an Enable Pin on HV side - correct? Why...

Hi,

the word missing in the rules is "conformal" - see here for explanation. That´s at least what standards I know refer to. There´s multiple companies producing such "conformal coatings" and some...
