@BLUETTI_CARE,
I’d like to draw your attention to this topic.
I would appreciate both recommendations and feedback on this topic. Below are my thoughts on the matter.
I also use this station, but because the station was displaying inaccurate current power, I switched to the AC180 model and put the Elite 100 v2 in reserve and have barely used it for the past couple of weeks.
Indeed, many users on sales platforms report that the station has turned off and won’t turn on.
Analyzing these messages, we see the following in common:
The station has discharged close to zero, or in several cases it has charged to 100% and then stopped turning on.
Most often, people mention that the station was used in UPS mode.
The problem mainly affects those who have used them for three or more weeks.
The main symptom is that the station won’t turn on. For some, it refused to turn off a couple of times and then refused to turn on.
To summarize, a very common problem is the BMS going into cell imbalance protection mode This is my opinion based on reviews and user reports of problems.
There could be many reasons for this:
Hardware issues – bad (unstable) battery cells.
Low balancing current due to incorrect balancing resistor components, etc.
Software errors – the balancing circuit’s start threshold is incorrectly selected, etc.
But these are just assumptions. Only a service technician can know the true cause
I’d like to point out the volume of complaints, and Bluetti should quickly address this and release new firmware, which, if not completely solves the problem, would at least reduce the likelihood of the station dying.
Until I have a clearer understanding of the problem and possible solutions, I’ve decided to proceed as follows:
Minimize use of UPS mode and use the charger in discharge/charge mode.
Charge at a low current – set the manual charging current to 1A in the settings, which corresponds to a charging power of approximately 230W. This will double the charging time compared to the Standard setting, but will also allow more time for balancing.
Do not discharge the battery below 10% or charge it above 95%.
I hope this will help me wait for a solution from Bluetti.
I would like to ask for your comment on the situation with the widespread failure of the chargers.
For confirmation, I’m providing a link to one of the stores that has reviews for this model, where you can read how many people have written about the problem in recent days.
If by any chance some Bluetti higher-ups are reading this, your entire R&D department should be fired.
If it’s not a colossal failure, I don’t know what is.
No, no one needs to be fired. We need to figure out and fix the problem first.
Regarding the differences between the models. I think the only difference is the color of the lettering. )))) Most likely, the Premium is the same as the Elite.
So until there’s more clarification, I recommend switching to manual charging current setting at 1A. To do this, click Custom at the bottom of the charging setup program tab and set the current to 1A. If you still need faster charging, then charge the Standard model to 80%, and then manually set the charging current to 1A.
If my assumptions are correct, firmware will soon be released that will slow down any charging process at the end and charge slowly to balance the battery at the end.
@lavash_bluetti As far as I’ve seen, with standard charging, starting at 98%, it switches to a lower charging power 200-300W. The Elite 30 V2 behaves the same way.
We need to figure out and fix the problem first.
