BMS recommendation/ experiences?

Electric Vehicle Discussion List mailing list
Hello, I've been driving my Dakota truck EV conversion for over 7 years,
and finally pulled the plug & bought a lithium battery pack. (46 CALB
cells, which should arrive this week!). Now I'm looking at BMS's, and am
curious if anyone has any experience with the Thunderstruck BMS? (
http://www.thunderstruck-ev.com/bms/ ). Positive/ negative experiences from
anyone who's used it would be appreciated; I'm also considering Lithiumate
or Orion, but those seem quite a bit pricier. Thanks!
Philip

Re: BMS recommendation/ experiences?

Hi Philip,

I talked to Mark from Thunderstruck some months ago about their BMS, it is
a really nice equipment and very accessible on price. But I was unable to
use it since it was on its end of development stage by then.  But as
reference, I can 100% recommend their EVCC (Charge controller) which was
designed by the same team, if this helps.

On the other hand, I can tell Orion BMS is one of the best battery
management systems I've use so far. It is quite complicated to wire and
install the first time (I've installed several of them) but is Pro device,
really close to a car OEM BMS. And just for reference, I uploaded a 32min
YouTube video for a friend of the main wirings:

that helps, great!

(video transcribed& translated): BMS recommendation/ experiences?

Electric Vehicle Discussion List mailing list
For those that are not fluent in Spanish, you can mute the video's sound,
turn youtube's cc on & set the cc to auto translate into English.  Below
that is the page's transcript, converted into English & some time stamps
edited out for read-flow.

Basic configuration of an ORION BMS, Technical Video
Marco Gaxiola
Published on Aug 1, 2017
This is a technical video about the BMS systems of the ORION-EWERT
Technologies brand, which in my experience are some of the best systems
available in the open market for energy management with lithium batteries.
They are not easy teams to connect, or to configure, and although this video
lasts 32 minutes; I only manage to cover some details, tips and minimum
recommendations. However, it will help those who are initiating in these
systems. The connection and installation of these systems must be done by
people with knowledge and professional experience in EVs and lithium
batteries.

00:00
ok I'll start with the exception of
all parts that contain the schedule or
there is a meeting system although the
first connections and the most
important are those of the salty is the
physical earth then has in this volta
a cable of many colors with several
cables of many types have two
drivers and so on
00:30
this cable is what keeps all the
data communication
the campus that connects the battery of
auto to battery charger to many
other parts of the vehicle though
after here comes another cable is
that there are only two requirements
slim eye this cable so low
voltage or not
00:53
all this everything will remove opera
with 12 volts with the car battery
normal because we are going to prepare the
high voltage battery that is the bank
of battery main battery
12 volts in the whole territory for
operate under voltage this case of success
01:09
that come to more 2 222 wires here
in orange and black goes in this part here
he is in charge of monitoring the
Main voltage of the battery bank
principado sa is practically going
to study the lithium bank for
batteries throughout the system the
homeland are on this side
01:32
this cable will monitor the attack of
main battery bank what more
we have have apart we have installed
another one a month that the one that is going to change
this one is also dedicated to
monitor the battery bank
main but here comes a droplet and
this one obviously
01:58
a historian others more the current
that flows into the system through this
inductive census this sensor
practically what you have to do is
of the battery bank happens either in
positive or negative
02:11
those who go towards the engine I'm
assuming that the engine is
opposite or the traction system and the
bank the fair after one of the two
cables go through the census
then the current that industry
within the defender the very capable of
monitor with that constant monitoring
principal and with this the
current and these additional cables that
there are four sensors here
02:35
temperature they call territorial and
They are practically some bags of
plastic that come here in submerged
in plastic you are already received then
02:44
these four sensors we can
schedule three of them can go well
in the condition in between the
batteries
02:52
depending on how they fit in and one
can be used at room temperature
02:56
temperature is doing in the
outside and what temperature it has
internally the batteries between more
stuck between the cells and all these
factors is better this this is because
one out and all the icons but this
it would be the other part
well out of here and nothing else
03:14
we have to call it Celtic in this case
they are efe cam I will send those harnesses
to there and to here and in this stadium
is configured for a package of
48
03:33
so that's why they're banking
here we have a block of head
yellow then a block of red wires
and an orangeade each block are 12
03:45
here we have 12 24 36
03:50
then we need another one with this more
03:53
to have 48 and that side here
03:57
where we have the Celts who call him not
puts
defend the first set up of the defense
04:03
we are towards me is that it is of the
Logo part of Orion logo
04:09
here comes number one number 2 and
number 3 of Inca with Hector brings
only three groups one two and three
04:18
the first group etc
04:21
well the first three groups the group
1 which are 12 cells of the analyzed
04:25
then the second group that are the reds
04:28
the third group which are the yellow ones 12
24 36 and the fourth group in this case
04:34
nothing else come loaded with 12 because
already with this the 48 are completed
