This really is massive. It confirms a lot of ID's we now new about, but additionally rectifies Completely wrong/out-of-day ID's and adds new ones we failed to understand about. At this time, the quantity of accessible CANBUS messages about the Orion BMS two is working lower, so we are going to have to decide on and select A very powerful kinds.
I have bought JK BMS and received perplexed, and nobody can respond to me. When getting i have picked out CANBUS Edition, for the reason that during the guide I discovered this line:
The ID Buzz is sweet to generate – it can dash around motorway speeds faster than lots of typical loved ones SUVs, including the 1.5-litre petrol-engined Volkswagen Tiguan – and is particularly endlessly spacious, indicating more space for travellers and baggage than you'd come across within a Jaguar I-Speed or Tesla Model Y. And in LWB variety, It really is one of the most spacious cars You should purchase in any class.
myles said: Large voltage batteries are definitely the way of the future obviously! If the Do it yourself lifepo4 BMS world could help 100 cells in collection. You would be at 480v nominal! What could probably go Incorrect Simply click to develop...
I did observe reduction of discharge limit current as the pack SOC dropped, but I didn't notice these limitations tapering appreciable as limiting small mobile voltage price approached my prescribed decrease limit price of 2.8V. The BMS had to open up the contactor to avoid wasting the lowest mobile, so Most likely much more than the SOC is miscast in the interpretation from .dbc to .o2bms string.
San Diego Apr 26, 2025 #25 Adhering to up: the SOC overestimation difficulty inside the inverter is unrelated to the volume of battery enter terminals made use of. Silly thought on reflection, however it gave me something to check whilst I'm trying to find extra Strategies and information.
As outlined by our special data, the Volvo EX30 in Twin Motor Functionality As well as kind would be the electric car or truck that may keep its worth the most beneficial throughout 36,000 miles or a few several years of ownership. Certainly, it'll find more be worth almost 64% of its primary benefit following that time.
In battery backup manner the inverter can offer energy approximately its output Restrict or perhaps the output Restrict of the connected battery, whichever may be the lessen.
EDIT: I did not see my previously post where by I realized you had been also discussing the High Voltage DEYE inverter with large voltage batteries. Before I had an first Orion BMS and talked with Orion concerning the CAN protocol and found that it's not implemented on that BMS.
Excellent factor the vehicle makers by now built and bundled a sturdy BMS inside their packs. This makes it SO less of a challenge plus more reliable. As well as safe in not being forced to open up the packs. This is actually the technique to go.
This electric Hyundai starts at $37,850, which is not affordable, but it's actually not poor as far as EVs go. There are 4 trims offered, and among These trims are choices for possibly RWD or AWD and typical as opposed to extended batteries. When sorting as a result of your decisions, the specs boil all the way down to this: The ideal power arises from These with all-wheel travel plus the extended-vary battery, which make 320 hp and 446 lb-ft, but the best selection originates from the SE trim with RWD and also the prolonged battery for 342 miles.

The poor aspect of this is the fact when Goodwe thinks the battery reaches 100%, it stops charging, Though it truly is at a special SOC in DALY.
i. the off grid inverter should have an influence output limit, you can only go through a great deal electrical power and This can be considerably less than what you require sometimes - a grid tied program can typically offer Significantly greater latest.
