Re: [EVDL] Towing with a Bolt

2017-12-01 Thread Haudy Kazemi via EV 
A more complex answer is manufacturers promote or don't promote towing 
abilities as part of market segmentation. In some parts of the world, a vehicle 
model is tow rated but in other parts the same vehicle isn't rated. Depending 
on local factors this may either encourage or even force people to buy tow 
rated vehicles.

Tesla built the Model X on the same platform as the Model S but only offers 
factory towing option (and towing related software) for X. The Model 3 is su

Toyota finally added a tow rating to Prius, although people have been towing 
light trailers and teardrop campers (<1500 lbs) with them for years (see Prius 
Trailers group). In terms of weight ratios, a 1500 lb trailer compares 
favorably to a 3300 lb Leaf, 4700 lb Model S, 5200 lb Model X, or 3000 lb Prius.

An experienced driver with a balanced trailer and well secured load, who keeps 
speeds and following distances that are in proportion to what is being hauled 
will be fine. These drivers know they need to leave extra space to start and 
stop. These drivers also account for weather and road and terrain conditions. 
Expectations and planning makes a difference. Much less capable vehicles towed 
much bigger loads in decades gone past.

Inexperienced drivers probably should not be towing. Otherwise experienced 
drivers who haven't towed before should start out with lighter loads and 
conditions to build experience with the changes in driving dynamics that towing 
causes.

Easy answer is. some vehicles are designed to be able to tow and some are 
not. It doesn’t matter what they use to propel the vehicle a lot of trains are 
electric and they tow a lot of weight.

I tow my 15' old 40 HP boat with my prius.
Also tow my Communications trailer with the prius.
These are area tows... I'd be stupid to try to go 100 miles at 70 MPH doing
this.
But stupid is out there it’s a lose-lose proposition to try to make one

It usually comes down to three things-Warranty, design load and pilot
expectations.If the manufacturer does not want to take responsibility for
the unheard things that some people manage to do with a hitch, they will
simply say that a hitch voids warranty.The design load of the frame will
limit how much extra load the car can take before things start to deform and
since an EV is designed to be light, there may not be too much margin. Note
that it is not about the static load on the hitch ball, which is supposed to
be pretty low for a well loaded trailer, but the dynamic loads, especially
for a non braking trailer can be pretty high and tear on the frame.Then
there is the issue of expectation. Drivers might expect to be driving their
usual 70 to 80 mph and either put themselves in danger by exceeding the
capabilities of the car or be dismayed by the limitations, not leading to a
positive experience and if the towing feature is not a selling item then it
won't be valued as such.

Towing with a Bolt Hi All,
   My bro asked me a question I never worried about with Civicwithacord, nor
my LEAF: Why is it so bad to toe with an EV?/Warranty voiding?

My first answer was of course, range drop with rolling resistance and added
weight requiring more amps.
My second answer was guessing that more amps mean more heat as well as worse
voltage sag on the traction pack. But am I missing anything else?

Towing with a Bolt
]

The question posted asks about towing with an EV in general. I feel others
have answered that.

But the subject/topic of the post specifically asks towing with a Bolt EV.

I would first see what others have done, by checking with what the Bolt
drivers have posted
https://www.google.com/search?q=chevy+bolt+towing

And then, because the Bolt's underpinnings are based on the Chevy Sonic ice,
you could also look to what the Sonic drivers have posted
https://www.google.com/search?q=chevy+sonic+towing

Which btw also gives:

https://www.etrailer.com/vm/Chevrolet/Sonic/hitch
Chevrolet Sonic Trailer Hitch
For your 2015 Chevy Sonic the Draw Tite Hitch part # 24878 has been
confirmed as a fit and will work well for light towing as long as you stay
under the hitch's towing capacity of 200 lbs tongue weight and 2,000 lbs
total trailer weight and the towing capacities for the vehicle listed in the
owners manual.


That last bit is what you should have already read (the Bolt manual - rtfm)
to know the Bolt EV's design limitations.

I would worry about the trailer exceeding the limit of the brakes more than 
anything. If you are talking about a little 4x3 Harbor freight utility trailer 
for flat ground around town use thats one thing but anything bigger might be 
unsafe especially in less than optimal conditions

In addition to excess wear on the tires, you may be depressing your shock

shocks at worst.

There's no issue with volts or amps; the primary thing that will happen as
far as electricity is concerned is that the car won't go as far on a full
