If u have additional then two u really need to use extra interfaces. The Rs485 are going to be use to communicate between interfaces and Learn CAN port will rapport to bms.
There’s 1 widespread criticism I listen to regarding the Lightning and Rivian from gasoline truck guys. They dismiss the R1T and Lightning as abundant Adult males’s playthings, not effective at the major-responsibility hauling they do.
allow, or disable. They authorised a number of batteries, and PYLON is one of them. I'm not guaranteed how they acknowledge

I did observe reduction of discharge Restrict latest given that the pack SOC dropped, but I didn't observe these boundaries tapering appreciable as limiting small mobile voltage benefit approached my prescribed lower Restrict value of 2.8V. The BMS needed to open the contactor to save the lowest mobile, so Probably greater than the SOC is miscast in the translation from .dbc to .o2bms string.
San Diego Apr 26, 2025 #25 Adhering to up: the SOC overestimation issue during the inverter is unrelated to the quantity of battery input terminals used. Silly assumed in retrospect, but it surely gave me anything to test when I am looking for extra Strategies and data.
do you simply go through parameters from your JK BMSes or also can function the switches or modify parameters?
In this case, the battery's BMS tells the DEYE Inverter what voltage to use and what currents to use. Then the DEYE does just what the BMS from the battery tells it to try and do. Click to increase...
Excessive V and you simply injury the battery. Far too fewer and doesn't charge. Also you should limit the charging A not byd car stock to exceed like 0,5C (by placing the charging V decreased quickly).

I did my best to develop the alarm flags according to the alarm desk furnished by the CAN specs document and, from analysing the Stay CANBUS, all alarm flags the BMS is sending are off. There should become a misalignment in several CAN frames, or it might be an interior alarm flag raised via the inverter internally. In either case, it isn't go here going to appear to be messing With all the operation of your inverter up to now.
That’s why we conduct an annual reader survey, during which we question motorists of every byd shark kind what topped their list of priorities when buying a new vehicle. Allow me to share the highest 3 things to consider among the electric car purchasers:
Some packs have an inner 48V and use a lift converter to produce three-800Vdc from it, some place loads of cells in collection.
Itsmejonny explained: I am a newb to photo voltaic and battery storage so with Having said that would the BYD 24V LiFePo4 Battery be feasible for RV electric power?
