Your reports are excellent thank you. You speak well and edit properly making for enjoyable and useful videos. Another user who I won't name is nowhere near your quality. Cheers.
Thank you for your informative video. Just checked the spreadsheet and noticed that with ECO mode and Regen set to high, you managed to get the actual 420Km advertised range for the ATTO 3 (WLTP). That was amazing.. the fact that the vehicle can actually be faithful to its advertised range is great and tells a lot about it.
Great work, and thanks for sharing 👍 I have never bothered testing the range since we got our Atto 3 in December. It’s good to see the difference between sport and eco modes isn’t too significant.
Drove down from Olinda Mount Dandeong to Glen Waverley last Saturday. Two people, sport mode, high regenerate. 25 Kms used 1.3Kwh with cost about 1 cent per km. Only used brake twice from Olinda to Burwood Hwy. Also full aircon 25 degrees and seat heating as well. Amazing car, love it so so much. The steering so precise just use one hand all the way up and down the hills.
Agree your general observations. I live in a rural area with an Atto3. I have found the type of driving conditions greatly affect achievable range. Additionally the car does lose charge when parked (up to 1KWhr per day powering its computer etc, its much better than a Tesla in this regard). So doing the test in a single trip should get you another 30km or so. I have determined the vehicles best range speed is 85kmh+-3 using ECO mode. Wind direction (headwind) noticeably decreases range. While you would think dead flat terrain would give best range it appears to get slightly better mileage in gently undulating terrain and speeding up on the downward slopes. Carefree range in my experience is 350km. This is fairly easily achieved with a useful bit of reserve. Dropdead range with basic economy driving (no special techniques) is about 420km. By practicing suitable hypermiling techniques (at this stage I havent yet worked out exactly what these are for the Atto, but it certainly involves speeding up going downhill) over inflating tyres etc, 480km to drop dead might be possible. I have heard of people claiming to have got over 500km, but that would certainly have had to involve a stiff tailwind.
well done test. Would be nice if you can mix some high way driving and city driving. I expect highway driving to have much higher consumption like over 20kwh/h
Thank you for this awsome video. Im planning to buy my first EV BYD dolphin 44.9kwh variant as im looking how the range NEDC of 405km compared to the actual. Based on your data, around 80-87% is the possible range. I live in asia so im hoping our warm weather will give us a better range.😅
Did you have the AC or heating on and how conscious were you of the range while driving? In my tests the range drops drastically to 320 if u drive normally without looking at power drain. I always suspected that eco/sport modes are just gimmicky and ur spreadsheet proves that. I also doubt if the kms shown by BYD is accurate. Maybe you could do a test on that too? Thanks for the excellent vdo. The only of its kind on the internet.
Be intersted to see what difference high regen and eco mode makes. I pretty much drive everywhere in that config anyway Edit - just saw the end - interesting!
Good work. I am interested in the highway/freeway run. would it do the 300+km in one go without getting into panic station? Wish to drive to sdyney from melbourne in my att0 3 extented
What is you battery feedback intensity set to? We get about 300km range but our drives are very very short distance, 170km/week but we drive it daily. Can get away with charging it once a week on 10amp charger.
What do you mean by feedback intensity? I had my regen breaking set to standard for this one. Also do you have the extended version with a 60.4kWh battery?
Watch atto3 owner's video on battery feedback intensity to understand, yes extended 60kw with 480km range display on full charge, at first I was shocked and was expecting over 400km, but the nature of our driving means just can't travel the distance, most of our trips are just 2/3/4 km from home, even the old petrol car was running out of fuel every two weeks/300 km, but would go 6-700km on the highways, from limited trips we did in the Atto3 we should get about 370km range on the trips to the mountains/south coast, so not bad.
What I found having done this is, the more you do with the car the more you learn about it. Knowing where the limits are in a safe environment will give you more confidence for when you actually need it.
Your kWh/100km is wrong. You just used the last 50km display. eG on eco mode 420km on 59,9kwh (99% of 60,5kwh) that will be 59,9/420*100=14,26kwh/100km
No doubt there will be discrepancies especially on days where I drive more than 50km and the data is not fully captured. Unfortunately that's the best I had available to me at the time and I made do with it ☺️
Congratulations, you just halved the lifespan of your battery. Just like a mobile phone, IF you keep it topped up and never let it get below about 50% it will double the lifespan.
Sounds like BS to me, especially saying keep it above 50%. It's a very reliable and well made lithium battery I highly doubt the occasionally low percentage is going to destroy it.
Hi, thanks for the video, really informative. Can you please let us know if you used the AC and music system during your test? My Atto 3 goes only goes 64% of the claimed range when I use AC and music. Your response is much appreciated.
Hi I actually got to 2% because a fast charger that I was travelling to was out of order, so I had to travel further than I planned. The difference was my Atto 3 went straight into limp mode as soon as I hit the 2 % mark, luckily I was about 300 metres from the charger. But I was stressed out to the max😵💫
, Thank you, ".. to 100%.." Does that means, it will do the balancing automatically during charging? If that was the case, then, "battery balancing" should not be an issue at all right? (ie balancing done automatically )
Thanks for sharing the result. I think it will be better that BYD will change the 480 maximum range display to a value based on the real driving efficiency in the next update. I had not tested the range of my atto3 so far. It is understood from your report that there is no much difference between eco mode high regeneration and Sports mode normal regeneration (20Km overall). Have you used adaptive cruise control during the range test?. Thanks you so much for this excellent video.
Thanks Ed for the very informative video. I will be getting one soon, and it is good to know its capabilities. Keep the videos coming. It would be great if you could do a highway range test (>100 km/h). But it would be scary to be driving on the highway with 1% SOC.
Subscribe button clicked. Your videos are awesome - you should have a lot more subscribers. I will be spreading the word about your content. I'm currently on the fence in regard to buying either an Atto 3 or an MG4. Tough decision for me TBH.
Nice video. One of the advantages of LFP batteries is you can push them. I’m looking forward to testing out the 650km range on my Polestar LR when it arrives in October. Stay tuned! Ps I’ll be working hard to keep mine between 80, sometimes 90, and 20. Should get around 12-14kwh/100 hopefully
I wish you also add the average speed for your trips to your Excel file. Kwh usage is important but average speed makes so much difference in calculations. I hope you also make a 90km and 120km average speed off city test like Bjorn in the future. Best of luck.
Well done. You're a brave man taking it down to 1%. So, from what you drove in actual distance was 70kms less than the projected distance. Is that correct?
Was the actual range @4:17 supposed to be 108.8 km / hr ? And I wonder if it would be feasible for suburbs to chip in for a charging facility that feeds power from home owners solar systems and batteries and they get paid like 5 to 10 cents per watt?
This was very enlightening. My dream car. Does it ever get very hot (over 34°C) in your part of the world? I'm interested to know How good the AC works in those conditions since Chinese cars tend to have crap AC. Best AC I've experienced in a car was in a Mahindra in the desert.
I used to average 14.5-14.8 kWh but not I'm getting 15.4-15.6. Not sure if it's the update or something causing it to spike. I used to average 420-460 for 100% now it's just under 400. Plus a ghost discharge when unplugged. Usually less than 3% per night.but I need to retest and retest again.
I've watch your video again and I just realised that you using around 13kwh which translate to 460km range. My average before update was 14.6 which translate to around 410km range. I don't understand how you get just under 410 range and still manage to pull less than 12kwh. Did you had some ghost discharged?
It will fast charge to 85%, at that point the charge rate rolls back. I generally don't charge to 100% using DC fast charging. I only charge to 100% using AC charge, leaving it on overnight for equalising.
I have done a similar test in January when I first got my BYD ATTO3 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-h-Q87Ef10EU.html It’s over 6 days , I never saw any phantom energy loss , means the project remaining mileage stays same over night , however recently I see whenever I keep the car overnight there is difference of 2km every time
This is cool! I was actually able to get to 420km on high regen and eco mode. I did notice phantom drain on mine too. Not sure what caused it...maybe overnight temperature change
Is there any difference or recommendations on charging everyday or charging only when your below a certain percentage say 30-50%. Will it be better for the battery in the long term if you don’t charge frequently? I know lfp can charge to 100% and are more reliable but wonder is it still good for it.
Not in particular. I just avoid either end of the extremes and charge whenever I have the opportunity. Occasionally getting it back to 100% to recalibrate the SoC reading.
Atto 3 Malaysian user here, I drive mainly in the city and the screen shows 15.5kWh/100km but its totally inaccurate, I did a full to full test. Distance travelled ÷ kWh added to full charge (the home charger app shows this data), it totals up to an average of 20kWh/100km. My setup is High Regen, Normal driving mode, AC on comfort, fan speed on level 2 and temperature set to 25°C, tyre pressures at 260kPa cold. Outdoor ambient temp averages at 36°C-38°C though so that might be the cause of the high battery consumption
I believe the non-motor draw on battery is up to 0.2kW so that's not going to cause your high consumption. I drive a mix of highway (to 110kph) and suburban and get very little variation from16kW/100km. I actually drive in sport mode with highest regen and my other setting are similar to yours. I mostly charge at home and with the most recent electricity price increase it costs me less than $5/100km.
@@qilu2004 true, hence why i believe its more accurate to calculate before counting for energy losses, because you pay for electricity based on the kWh transferred to the car minus the energy losses
@@PsychedMedia all evs calculate energy efficiency based on what got into the battery, rather than what got out of the charger. if we are to compare efficiencies, we need to use the same criteria. having said that, u should get your atto3 checked. its energy consumption seems abnormally high.
I am from Singapore and I did the same calculation as you and came up with 18.5kwh/100km. Total distance travelled / kWh charged. My A/C is set to 23 celcius and on auto.
