1993 Chrysler TEVan - BEV
We needed to
see the individual
voltages on the
30 batteries to
asses condition
so this is what I
thought up.
The meters mirror
a typical battery
box. 3 batteries
in the front row
and 3 in the back
row. The wiring is
set-up to feed the
meters so the left
meter is the left
battery, center
meter the center
battery, etc.
All I have to do is
plug the RJ-45
link into the
appropriate row
selection RJ-45
and it reads that
rows voltages in
proper physical
order.

Here is a
close-up of the
meter system.
Each meter
requires its own
power supply, the
black AAA boxes
as pictured.
DS and PS stand
for Drivers side &
Passanger side.
The physical
layout
coordination is
very important
now only for
servicing, but for
understanding
the effects of one
troubled battery
on the adjacent
units.

This is the battery
box interior wiring
plan. Although
shown as crossing
the battery, no
wires cross any
other wires in this
system.
There are 2 RJ-45
boxes for each
battery box, one
front and another
rear.
I acknowledge
that RJ-45s were
not the best
choice due to their
lack of
waterproofing; but
I have been
unable to find a
waterproof RJ-45
style alternative. I
consider that
choice the
weakest point of
this system.
Suggestions
welcomed, as
always.

Here is a view of
the interior battery
box wiring. The
wires are kept all
to the outside of
the batteries and
no two wires cross
each other to
avoid any possible
shorting.

would adjust that
to a much lighter
gauge if I ever do
this again.

I have added a
Dell LapTop to the
interior to
download to graph
data from the
e-meter. This
data shows both
charge
programing and
discharge
patterns. The
LapTop has its
own caddy and
mounting system,
and operates off
its battery as well
as the vehicle's
12v auxiliary
power outlet.

40 amp heat
discharges
followed by a pair
of charging cycles.
Note that the
second charging
cycle pushed the
voltage cycle three
times rather than
two. The battery
pack had been in
storage for many
months before this
event; and it
shows the
batteries starting
to come back to
life. Nife units
perform better the
more they are
used.
