The way I read this, batteries with BMSs that do not communicate are now obsolete:
If a shutdown condition is approaching a battery system should notify the operator with a visual and/or audible alarm before disconnecting the battery from the DC system.
ABYC E13-7
I think ABYC should have required all BMS to be able to communicate with charging sources. This could be as simple as a set of contacts, but CANBus is better. More here on why. And here on ways to do that.
The TE-13 technical note is now a standard: E-13. To me, a woefully inadequate one that relies far too much on the vendors to do the right thing, but it’s a start. Panbo has a good analysis, most of which I agree with.
I’m loving this little charger I bought. I will write more in an upcoming article, but the ability to check out, on my phone, exactly what happened in the last charge cycle is amazing. Tells me a lot about battery health and how to set up the charger best for our usage.
