You have no control over this...
The vehicle tracks the battery capacity and you are experiencing 'normal' degradation over time and charge cycles.
Perhaps you are on the low side of normal (maybe 48 is more typical for a vehicle with 53K km), but there is nothing wrong with your vehicle in my opinion.

Previous summer I have 90-95km, but my driving style was like grandpa)) At this summer I have 65-75km but driving like on accord 2.0t))

procedure "removing air" from the cooling system can help to increase BC?
You may achieve better results by rotating the air in the tires. Side to side, front to rear or an “X” pattern have proven to be equally beneficial. Keep accurate records. When the tires are rotated it may be necessary to rotate the air as well, so as not to have the air in the positions that produced the undesirable battery capacity measurement. There are several Tire Air Collection Systems available online.

You can laught but I do this. Like new. What I`m doing? Secret)
After my procedure - 88km after full recharge (previous was 67-75 max)

OK @MFKilla,
Spill the beans !
I have enough experience with this to know that you are not defying the laws of physics and magically rejuvenating the HV battery!
As you have undoubtedly read, we are aware of these phantom battery capacity resets, but we have been unable to definitively identify what causes them. Our best guess is that disconnecting the 12V battery (for an extended period) can cause this.
And, your 'procedure' definitely will not increase your actual range... You may get an artificially high reading out of the Guess-O-Meter, but you will not actually achieve those miles and the reading will return to normal in due course.
So, please enlighten us as to what your 'procedure' is - It would benefit the group to know what not to do in order to avoid a phantom capacity reset. Is it an extended disconnect of the 12V battery (how long), or is it something that you do with the infotainment controls, or in the OBD2 settings?

My 12v battery connected since february 2023)) So it`s not a battery. My friend bought Clarity from Copart about a month ago. When it arrive to him I could check my theory and write you procedure if it works again.
PS: What about range. Today I drove my regular trip + special did additional kilometers to drain battery. All 88km was on battery.
My tg is @MFKilla. You can write to me and I will share my thoughts on how to do this.

Do you believe that new EV batteries only charge to 80% and discharge to 30%? Do you believe that any new EV will achieve its claimed range by using just 50% of the battery capacity?
Battery University has some pretty hair-brained ideas, and they seem to spread quickly.

17kw battery use only 13-14kw capacity. Other is for replacement of failed elements
I’m thoroughly convinced that you have very little understanding of the topic.

realy? I'm waiting for your explanations.
It isn’t worth the effort.
Perhaps you could attempt to explain how the “unused” 3-4kWh’s of capacity might be used to replace failed elements.
Another “secret” maybe?

Have you never heard of software? Even the smallest power bank has its own microprogram for managing work with currents and elements.
Maybe then it will be a big shock for you that you can see failed elements in i-HDS (Honda Diagnostic Software)? 2 blocks A and B. And for each there is a test with graphics. It’s also no secret that the total battery capacity is 17 kWh, but with a fully charged battery you will never charge them. Maximum 14.
For example. A completely discharged battery was charged at a 7 kWh charging station, and only took 12 kWh. Where is another 5kWh?

You will never come to an end of an exchange with this guy. He sold his Clarity a short time ago and bid farewell to this forum, but here he is again.
Best advice is to do what he has done to probably 85% of members of this forum and use the IGNORE feature for his posts.
The battery has a potential capacity of 17kWh’s if each cell is fully charged to 100% and then discharged to 0%. At 4.2V a cell will be charged to 100%. The target charge voltage on the Clarity is just over 4.09V, that’s about 90% of a full charge. Likewise there is a similar “buffer” on the low voltage end.
A 100-0-100 charge cycle is less than ideal for the longevity of a lithium battery.
You seem to be suggesting that there are 3-5kWh’s of capacity waiting in the on deck circle to replace a bad cell or two when they fail. That isn’t how the battery is wired and software isn’t going to solve that dilemma. All of the cells are being charged from a specific voltage to a specific voltage.
It is certainly possible that the charging protocols could be modified to achieve a lower cut off voltage and a higher target voltage, thereby allowing the user to access more of the available capacity.
I hope that helps you understand how these things work.
It’s interesting that you’re not even following your own best advice.
Why not allow each individual to be their own editor. There’s a good chance MFKilla could learn something here through the continued exchange of information. Not everyone is that smart.
Thanks for reading my posts.

My mother told me not to communicate with toxic, so it’s unlikely that we will have a dialogue. I doubt that you can teach me anything
