ABRP Blog

Thank you very much for sharing the data you have collected and keeping ABRP uptodate with the real world charging curves!

The curve for the 85 kWh battery is exactly like mine. The drop came with  the 24.4 sw.
Charging from 10 to 60% takes 22% longer now :(

How’s the real world data for the battery pack in the SR+? Are you starting to gather enough data points to start sharing that? It certainly seems artificially limited... so I wouldn’t be surprised if Tesla starts to tweak that based on crowding issues and more long term data collections.

Good point! I just added the data and new charge curve for the SR+ too. 

You updated the 100 pack to the ’peak’ graph but did not do this for the 75? Similar max 127kW shadow is visible on the 75 data. My X consistently pulls that 127kW.

 

 

"Our standard charging benchmark from 10 kWh to 50 kWh has changed from 29 minutes (May) to 34 minutes (August) for the BT37. No disaster, but also not so fun for S85 owners."

Hi,

regarding your "standard charging benchmark" as stated below the second graph for BT85/Model S85. "from10 kWh to 50 kWh", I presume you are referring to soc (state of charge)? Which figure are you using for an Model S 85 were you have API access through a token? Do you use NR (nominal remaining) or UR (usable remaining)?

28th June 2019 my battery reported a NFP (nominal full pack) capacity of 65,5kWh with an energy buffer of 4kWh thus a UFP (usable full pack) of 61,5kWh. At the moment of data collection, the SOC was displayed in the car with 71% which is referring to the UFP & UR figures: UR 43,7kWh are 71,1% of UFP 61,5kWh.

Do I presume correct, that you calculate the "standard charging benchmark" individually and according to the reported UFP figures?

As an example, when my car is connected to a SC with e.g. 9%, this equals individually for my car to 5,54kWh soc. Your benchmark will start counting when my soc reaches 10kWh/16,3% and stops when hitting 50kWh/81,5%. this takes currently 49 minutes according to the logs of my car. I compared several charging sessions and came to the same time. I ensured that up until 12% soc the SC was able to provide 114-116kW, thus external limitations would be neclectable.   Is my Model S85 so much worse than most of the others? ...thanks for the great work! BR Oaito.

PS: Since the quoted sentence is referring towards Model S 85 you probably put in the Battery Type BT37 by mistake.

2PS: I use teslalog.com for data collection. Are you still interested to add a 2015 Model S 85 with 185000km (HV battery replaced at 107000km)?

My 71.000 km. 2017 S 90D (BTX4) in one week and with the same firmware V10 version 2019.32.12.2 is reducing max power in every Supercharge (I did a 2.500 km trip)

Power in kW: 111 -> 109 -> 106 -> 103 -> 101 -> 99 -> 96 -> 94 (and now it's the 5th supercharge at this speed)

Before V10, the last three month, max. was 118 kW and before this increase it was 112 kW.

Could these tests be performance again? Maybe also looking at differences between US and EU?

I'm not getting any such results for my BTX6 Model S 2018. I got better results last summer but it seems charge performance is decreased.

 

 

How can I adjust ABRP’s overly optimistic charging times? It thinks going from 21% to 88% will take 34 mins, but I know it takes about 50 mins in mine (assuming unshared charger) this is S75D late 2018, 12000 miles, 80% charged at home.

You should consider splitting the 100D into their individual logical groups, classic 100D, Long Range, Standard Range. We all know that there were changes introduced in the hardware for charging the newer Long Range/Standard Range versions. The above gives the wrong illusion that all 100D charging speeds are better. Mine is a 100D; my charge curve is not even close to what you project as a benchmark. Agreed that you show all data points collected, however splitting this could be beneficial along with Charger location max speed (i.e 120KW/150KW/250KW, etc.. if you collect that data).

The charging speed on old 85 has got worse after summer again. At 30% you get only 70kW, the peak over 100kW lasts for few seconds only. 
 

could you publish new data from around December maybe?

Have you managed to identify any data from the v3 superchargers yet?

Hi, could you publish a refreshed report? As stated above, 85 seems much more slowed down, according to several TMC users (me too), but having a view with your more representative sample would be better data to understand the reality. Thanks

The slowdown on classic 85 is much more severe. Me and 2 friends are seeing an average of 44KW@50% which used to be ~70KW. That is a mere 40% reduction. Unbearable.

Same here, driving a Model S 85 since November 2015 and for 225000km, mostly long trips two times a week through Germany and charging at SC. The increase in charging speeds due changes in the BMS is considerable. I wish also for more different models. Or adding a "charging speed degradation" offset one could try change the curve and find the matching one for his own car.

 

Thanks in advance! oaito.

Any chance to publish updated info? Tesla claims Ravens charge at 200kW and old S 85 owners claim the charge rates have plummeted.

Some of these graphs have large areas of blue "smear" - does that relate to non SuC charging? Or just that some cars can't maintain the faster rates?

@Bo (ABRP)

There's reports that Tesla Superchargers in Europe aren't doing more than 120KW at the moment ( https://insideevs.com/news/437810/tesla-limiting-supercharging-120-kw-europe/ ) - I was curious if this is visible in ABRP data?

Nobody to answer about refreshed reports ?

Hi @Bo-ABRP

I've been playing with the data you published (colored lines below) and matching it with the little data set I have from my own car (grey points below).

I'm wondering - can you give some insight into how you fit your curves to the data?

From the plots above it looks like you are fitting an upper bound and not averaging the data set itself - is this correct?

Thanks,

José

 

 

+1 for update on charging times please.

Looking for data on old v new Sr+ please.
