Possible to utilize 200V traction power?

Can the 200V power be utilized to power big demand electronics? Can I power something like a dual voltage welding rig with it? I was thinking of running the engine to keep recharging the 200V battery as it needs power.

Just wondering if the safety plug in the trunk can be modified to output 200-240 volts. It's basically like a switch to disable ALL the HV power, so can that be done or am I risking burning some of the wires for drawing too much power from there?

They call it a "switch" or "fuse" so this implies it must handle 100% of the power used to power the starter and electrical propulsion, which undoubtedly is quite demanding.

 

I think I read that the amp output of the HV battery far exceeds what I've read about low-end retail welders under $1,000, but it would be nice if someone could find out the real number.

If the switch there is supposed to handle 100% of the energy, then wire thickness limits should also be fine.

The inverter probably does not have an easy exposed plug like the trunk battery switch, plus it will only produce power when the engine is on. The Prius will turn off the engine when it is warmed up and the HV is charged, which means it will shut off regardless of your use of the welder.

The 200V HV cell seems like a perfect match for a 120/240V generator given that power is unlikely to exceed 240V and unlikely to drop below 120V. The drop in energy will tell the computer to restart the engine when power is low so you will actually save on gas compared to a standard generator, which will always be on regardless of welder usage.

The only question is whether the welder can handle DC. The manual for it only says it uses 120/240V. No mention of AC or DC where input power is concerned.

I suspect the power usage will not affect the car electronics since the electronics are on the 12V system, not the HV system. They probably just share a ground and nothing more.

 

Maybe not such a good idea after all:

Looks like there are voltage drops when the engine starts and then a huge surge to 300V. I doubt most 240V electronics will reliably handle that. Certainly not without a voltage regulator between the car and the device. And at that point you may as well get a generator.

 

Some units accept both dc and ac. Their manual does not specify it either way so I asked them.

Regardless, it probably won't work due to the fluctuating voltage apparently seen by the HV system.

 

I wanted to but someone told me those Chinafreight generators fail after 400 hours from engine wear, if their electronics last that long.
