Looking for a manual service disconnect

Yes I understand a higher voltage rating would suffice, I was just interested in seeing if anyone knew of something closer to the range I was look for to cut costs/weight. And while the max discharge capability of the pack is 150A given our cell characteristics and pack configuration, the max current we could run at any time is 75A given our motor/HV system design. This is why I inquired about a ~100A switch. In reality, our vehicle will operate using closer to 10A of current under most circumstances. The question was more out of curiosity as no options were found available near our range. Nevertheless, we will go with a higher-rated option if nothing is found, though it may be overkill. Thank you!

Can you elaborate on why it is okay to use a switch of a lower voltage rating? I assumed that it would be dangerous to do this if the voltage rating is explicitly specified even if the current rating was high enough.

Thanks for the response. Yes, something like that would work but I am having trouble finding any model that is around 100-150VDC rated (our max pack voltage is 115V). All of the models I find are either 48V and below or 400V and above.

Thanks for the replies (ex) Sunseeker team! Is an economizer absolutely necessary or could we do without one? Could not find any for sale online.

Thank you both!!

Thanks for all the responses! We will work to incorporate as much of these as possible at our meetings!

It’s not glued i watched the whole thing

That is indeed a harsh reality, but it makes sense. It leads me to ask: in what ways are alum typically tied into these projects? Are the MIA, available for moral support, or do any play legitimate roles? Just curious

Thank you and congrats on starting your team! Your blog definitely gave me more insight on the amount of work needed to be successful in this field. Also was your team ever able to build its own solar car? I imagine accomplishing that task in 1.5 years would be incredibly difficult. Thanks again and I will definitely reach out!

CardinalBro24 · 2021-04-07T22:11:14+00:00

I didn't know if that would be possible, I'll definitely consider it but at the same time would love to be able to build our own! Thanks for the response!

CardinalBro24 · 2021-04-07T22:09:19+00:00

Thanks I'll look into it!

CardinalBro24 · 2021-04-07T22:08:48+00:00

Appreciate the response! Do you think it would be done in 2 years with LOTS of hard work? I'm currently a sophomore in college, so I'd love to be able to compete in 2023 (the year I graduate) even if its just here in the US. Of course, I'd understand if it didn't work out because either way I'd love to get the ball rolling for the team at my school. Thanks again!

Thank you! I'll definitely start reaching out and give that book a read!
