THIS IS USA FEDERAL LAW


49 CFR § 571.305 - Standard No. 305; Electric-powered vehicles: electrolyte spillage and electrical shock protection.


§ 571.305 Standard No. 305; Electric-powered vehicles: electrolyte spillage and electrical shock protection.

S1. Scope. This standard specifies requirements for limitation of electrolyte spillage and retention of electric energy storage/conversion devices during and after a crash, and protection from harmful electric shock during and after a crash and during normal vehicle operation.

S2. Purpose. The purpose of this standard is to reduce deaths and injuries during and after a crash that occur because of electrolyte spillage from electric energy storage devices, intrusion of electric energy storage/conversion devices into the occupant compartment, and electrical shock, and to reduce deaths and injuries during normal vehicle operation that occur because of electric shock or driver error.

S3. Application. This standard applies to passenger cars, and to multipurpose passenger vehicles, trucks and buses with a GVWR of 4,536 kg or less, that use electrical propulsion components with working voltages more than 60 volts direct current (VDC) or 30 volts alternating current (VAC), and whose speed attainable over a distance of 1.6 km on a paved level surface is more than 40 km/h.

Major takeaway - you can't have >60V anywhere outside the battery box more than 5 seconds after a crash.

Kill a first responder with your contraption after a crash, then have the lawyer you've retained for $25k convince a jury that he'll stipulate that you are the builder, you are the designer, you made the decision to ignore the CFR, you are the assembler, but you are not the manufacturer (because you are trying to loophole your way out of the CFR) of said culprit vehicle.

There is NO reasonable (what juries and judges do...they reason on facts) explanation as to why the 60V rule would not apply to a DIY electric vehicle operating on a public road or highway. None. You are all trying to rationalize why it should not and a judge ain't gunna buy your shit to get out of a negligence/manslaughter legal proceeding against you, the manufacturer. The only difference is a manufacturer offers goods for sale. Is that enough to get you out of killing someone? I don't think so.

You also stand a much better chance of getting extracated if you are in the local fire department's records as FMVSS voltages compliant, versus having firefighters stand around, smoking a cigarette (something you can't do around a crashed gasoline car) until they toll the time for your battery to self discharge below 60V. So, just before you pile into that telephone pole, turn on your electric cabin heater..

Yes - it even covers the need for clearance lights on trucks beyond a certain width which has now become a fashion statement with narrow minitrucks. But that's outside the scope of this thread.

Agreed. The poking into the battery box test is another one.
The main point you're missing is the trained/alert ones won't go near a DIY until an expert is on scene.

So, the first responder gets bumped to third responder, and then a fourth responder gets to use the firehose on your total bleedout.

The untrained FRs responding to a "sleeper" conversion, won't even know it's an EV until after the chop saw has cut the HV cables running in conduit (for "safety"...).

Ignorance and dismissal is powerful. Dunning-Kruger is affirming.

The sad thing is ignorance f*cks with my hobby in terms of it being banned unless I am a certified commercial shop. This is the BS I have to go through in restoring my bent Tesla. Do you really want to bust your butt, spend $30k, only to have a law that says you need a $5k safety inspection before you can get plates or publicly charge (even on a Level 2). Is that what you want?

Hence my persistence in getting through to the hypothalmus-challenged that are blind to what will happen if one responder gets killed and their family gets all activist.

It's bad enough EV jockeys get cut off on roads, teen daughters get chased down by pickup trucks in their Teslas, and you get coal-rolled if your EV window is open, by jacked up F250 diesels, now imagine one of them is the activist brother of an electrocuted FR tow truck driver (because the lucky rubber-gloved FD dude with the chopsaw exposed the HV cables that that the tow operator then happened to contact with his J-hooks).

True. Clearly marked, with a notarized DNR taped to the window.

Now, it's 7:30am, it's spread across 2 lanes of I5. Who gets to move it?
The pyro fuse serves a different purpose than the five second rule requirement.

An inertia switch should work ok - they're used to cut the electric fuel pump off in a crash.
