I'm putting a complete 2013 Volt battery in my Delorean in place of the engine and gearbox, with the front 30-cell module under the frunk in place of the gas tank and the remaining three modules (T-shaped, 66 cells) in the rear. I'll restore the connection between the front module and the rear three so that electrically it looks like a normal Volt battery. I have the BECM with its two contactors and three smaller relays, but not the module that sits under the passenger seat, hopefully I can live without it. The one thing I'm missing is CAN bus commands giving the cell voltages and temperature sensors, but do I need them if the BECM can handle it all that? What's the minimum information to and from the BECM that I can get away with?Vaughan Pratthttps://www.blogger.com/profile/00822118944987442194noreply@blogger.comtag:blogger.com,1999:blog-3663861364732240368.post-40251183068196735942019-07-21T14:15:27.837-04:002019-07-21T14:15:27.837-04:00Can the X1 connector simply be connected to the ba...Can the X1 connector simply be connected to the battery bank's plus connector (red and orange), and the bank's negative (black), in order to control the bank cell voltages? ... or does it need to plugged into a battery control center as well?

The Fault signal is on X1 pin 13 and 14. A Low will be a Fault that is transmitter to BECM. As expected, we don't know all conditions that may generate a "Fault" conditions. One of conditions is the Under/Over voltage condition for entire battery pack(205/419V) or a individual cell exceeding absolute Min/Max Voltage limits(2.05/4.4V) as documented on page 4427. See also page 4429 for more conditions. The temperature outside limits may generate a "Fault" signal. There are 16 temperature sensors mounted all over battery pack.

The Chevy Volt CAN bus that interconnects all BICM has one termination resistor built-in. Please verify if your CAN bus receiver has another termination resistor built-in or if it could be enabled/disabled.Anonymoushttps://www.blogger.com/profile/11783510593917258663noreply@blogger.comtag:blogger.com,1999:blog-3663861364732240368.post-50638749708539758342017-11-12T08:37:22.439-05:002017-11-12T08:37:22.439-05:00I don't have experience with CAN communication...I don't have experience with CAN communication. I don't know what hardware and software to use to get started. I bought "USB-CAN USB to CAN bus Converter Adapter For professional Notebook PC Laptop<br />( 300899053368 )" from eBay but couldn't get any data. Others have been successful in getting data but I'm not sure they figured out how to control balancing. Any suggestions would be appreciated.

However I believe the cell balancing is commanded by the hpcm2 unit. It will be very interesting to see if the BECM will work on the split pack. Please post your results. I am considering a similar use for a volt battery and am very interested in what you find. Solar Guyhttps://www.blogger.com/profile/01854292593270253599noreply@blogger.com
