When he’s not hectic with his day task as professor of computer as well as automotive engineering at Weber specify University, [John Kelly] is a prolific producer of academic videos. We discovered his video tracing out the 22+ meters of high voltage cabling in a Tesla design S (below the break) rather interesting. [John] does alert that his videos are extremely in-depth as well as may not be for everyone:
This is not the Disney Channel. If you are seeking to be entertained, this is not the channel for you.
We ignored the alerting as well as jumped ideal in. The “high” voltages in the situation of an electric automobile (EV) like the design S is around 400 volts. Briefly, outside input by means of the fee connector can be single or three phase, 120 or 250 VAC, depending upon your region as well as charging station. This get boosted to a nominal 400 VDC bus that is distributed around the different automobile systems, including the motors as well as the battery pack.

He goes with each module, showing in detail the power routing as well as functionality, ultimately assembling the whole system spanning two work benches. We liked his dive into the computer-controlled fuse that just recently replaced the common style one, as well as were pleased with his complete utilize of labels.
If you’ve ever been curious about the high voltage distribution of a EV, get hold of some popcorn as well as inspect out this video. Glancing with his lots of playlists, [John]’s channel would be a great location to see if you’re interested any type of topic associated to hybrids as well as electric vehicles, drive trains, and/or transmissions. We’ve written about some Tesla teardowns before, the design 3 as well as the design S battery packs. have you serviced / hacked the high voltage system in your EV? let us understand in the comments below.
