Yes, touching 600v will hurt anyone and I agree with it. But I doubt this will be running for long distance. Probably this high voltage is generated around local area. And as such we have 100'sv created in cars to fire off spark plug anyway.
Again as you said, since we dont know the detail we have our own worries and I also share the same fear.
I dont think its very different than just 12V with very high current hazard. The only difference in 12V cannot go through human body but from short circuit or fire risk they all are same. Inface 600V will be less risky since current is less and any short circuit will fuse wire faster and create open circuit.1
On slide# 15, it is mentioned that battery sourcing 1600A @ 360V could generate 576KW theoretically...is it possible? I guess the voltage would drop drastically as the current increases,. Due to the internal source impedance...isn't it?
A colorful car slide show that stretched out a 17 line table into 17 pages of a slideshow. The key insight is that higher voltages allow lower amperages to flow the wiring harnesses and therefore lower gauge wires to be used. I recall trying to get a mere 1,200 watts out of a hybrid car for emergency power during a blackout. From the 12 volt battery, I had to draw 100 amps - and the thick wires still suffered voltage drops. High voltage (with suitable safety precautions) allows for a powerful powerboost from the battery on the road - and the potential to use the car as an emergency power supply with a suitable power converter. I'm still waiting for a vehicle to house emergency power capability. I've heard it exists in Japan - we certainly have a use for it here as well. Our electric company in Connecticut offers a simple adapter (around $600) for the electric meter to allow an external power source to feed the house without causing any problems on the grid. The car is much more relaible, much quieter, and much more powerful than an emergency generator. It also gets year round use and therefore is maintained in working condition for the unexpected instances when it is needed as a generator.
This is a good slideshow from our more mechanically-minded sister publication, Design News. Don't miss out on a chuckle on Slide 15. Plus engineers make some interesting observations, such as naperlou, who says:
"As more functions are powered by electricity provided by batteries, the load on the engine is lessened. This allows smaller (more fuel efficient) engines to power the vehicle. Charging the batteries using regenerative braking captures energy that was unused before."
