Re: [EVDL] Zilla 1141 error - 15mV drop across contactor at 100A

2020-09-06 Thread Matt via EV 
Hi All,

I thought I would post a bit of an update

I tried a brand new hairball that I borrowed from a friend – the new hairball 
also reported errors 1141 and 1124 when I tried to accelerate in any gear.

I had fused both contactor sense connections to the hairball, resulting in 
longer wires running between the contactor terminals and the hairball
Connecting the hairball directly to the contactor with as short a wire as 
possible resolved the issue, which suggests it may have been a matter of 
induced noise in the measurement, of too short a duration for my DMM to have 
picked up.
The noise issue likely hasn’t been sorted out, just that it is no low enough 
that the hairball doesn’t fault

High power demand under acceleration could indicate current leaking to the 
motor hull and messing up the car chassis ground (?)  Brush dust issues have 
kept me troubled too many times with weird problems.

Hi Brains Trust,

I have a Z1k LV.
My hairball gives me errors 1141 and 1124 when I try to accelerate in any gear 
(worst in 5th, and least bad in 1st)

The manual tells me 1141 is contactor high resistance. my DMM measuring the 
voltage across the battery and controller inputs to the hairball puts the 
voltage drop at 15mV for 100A (battery amps that is). Which looks about right 
for a  good contactor

The contactor always drops out when I turn the ignition off, and my DMM 
measures 92v across the contactor (measured at the hairball terminals). My 
conversion is 96v nominal (actual battery voltage is 102v, though the little 
white light on the hairball must act as a voltage divider, dropping 10v)

I opened the hairball, and it looks clean inside - nothing looks damaged 
visually.

Any ideas on what to check next?
Is it possible to see what the hairball is measuring as the voltage drop across 
the contactor?

thanks in advance,
Matt

This would work for many Fleet owners service trucks.  Some time ago a group 
I'm in talked with several who had the problem that their trucks didn't travel 
FAR everyday, but were started/turned off a LOT.  They had 3 year old trucks 
where the engine had died.

> I think the hubris f150 is supposed to get about 10 miles electric range

John  Lussmyer has spoken for himself, but I'll add that he's posted here in 
the past that his converted F-250 uses about 600Wh/mi.  So let's say that, 
as an irresponsibly wild guess, a lighter F-150 kitted out with some aero 
mods might get this down to 450Wh/mi.  

A 65kWh battery - not at all overly optimistic these days - would give 115 
miles of range at 80% DOD.  That's moderately useful range for some kinds of 
truck applications.  Whether potential buyers will see it that way is 
another matter.

One of the Rivian layouts has a 180kWh battery, which would give a usable 
range of 320mi at 450Wh/mi.  That's a lot of energy storage!  But it would 
make for a pretty pricey pickup.

There may be a market for an EV like this, but it's hard to imagine it being 
big enough to warrant the effort Ford is putting into it.  I wonder if maybe 
this is an exercise in developing an EV truck for EU and Asian markets. I'd 
expect them to use the Ranger as a base instead, though, since IIRC the 
Diesel Ranger is the largest selling pickup in Europe (not that they sell 
that many).

If they do nothing about the aerodynamics of a brick and the weight of a 
locomotive, it will take 150 to 200kwh packs to get the range the 
"public" demands. This will of course make the price prohibitively high.


John, how many pounds of lithium and kWh's does it take to get 60 miles? 
My guess; a lot.

Since I can get 60+ miles range with my F250, 4WD, supercab, longbed - using 
old Leaf Modules, I'm quite sure that Ford can get better range than that.
(and I still have a bunch of empty space under the hood.)
