We are about to install NVIDIA AGX Xavier to our vehicle and we are evaluating the proper way to do so.
Can you advise us with respect to the recommended installation and for additional measures we can consider, like power regulators or switches we can use to protect the system?
Our calculated total power consumption for the AGX system is at 12V*38A = 456W.
Having reviewed the “NVIDIA DRIVE AGX SYSTEM MECHANICAL INSTALLATION GUIDE” and your reference implementation of “NVIDIA Drive Hyperion 7.1 Developer Kit Hardware Installation” we have a few questions.
Section “5.3 Installation” of the first document only mentions a fuse for protection. Is this sufficient for vehicle usage of DRIVE AGX or do we need to do something additional? Does the NVIDIA Drive AGX have any other protection mechanism (excluding the AGX power supply) that we can rely on?
From the second document of your own installation on the Hyperion platform, I have also not seen any info, with respect to protection, fuses or voltage regulators. I see a “Battery Isolator/Isolator Relay control Signal”, which I suppose is your selected protection mechanism. Can you offer a bit more insight as to what that is? Is there an option to buy this or some similar solution for our system from you?
I also read on the Hyperion platform that you used an AC-DC inverter, for “offline” usage without draining the battery (ex when the car is not powered). This setup only transforms the wall power 220 AC to 12V DC and supplies CMC-1 SB50 terminal without any connection to the car battery, right?
Generally, we are considering the following set-ups, please advise us to what makes more sense to do. Specific or recommended products from the market that we can use would also be very helpful.
- 12V car battery → fuse → CMC-1 SB50 terminal
- Same with 1) but with some voltage monitoring relay to monitor voltage and disconnect at out-of-range voltage (ex <9V or >15V). How fast should these systems react?
- 12V car battery → fuse → DC-AC inverter (12V – 220V) → AGX power supply/ AGX power adaptor → CMC-1 SB50 terminal → DRIVE AGX. Here I guess we would utilize any protection mechanism found on the AGX power supply itself, I have also read a few people trying this from forum posts in here. I read on the Hyperion document that you use TS-400 DC-AC Inverter, would this one be a good candidate for that? It is at 400W less than our max 540W but maybe it would be sufficient since you use it on the Pegasus of the Hyperion system and in general, we should rarely face the max output of the DRIVE AGX platform.
