BYD Atto 3 - My charging setup

Charging to extend battery life. Best practices.
More information can be found on p92-93 of the Atto 3 owners manual.

Good sensible advice.

[@JesusmyLordSaviorand]

Great information regarding state of charge and calibration. I might add the lower the amperage during charge the better it is for the health of the battery. I can share the information from electrochemical and also research on EV battery from a University .

Thank you. If you have a link to the info, that would be interesting.

Hello EV switch, thank you for your detailed presentation, I couldn't have said it better. Sorry for German language, my English is bad, it just takes too long. A translator for reading is faster. We live in Northern Germany. It looks exactly the same here with all the wind turbines and cornfields. Für meine Frau und mich möchte ich einen BYD Dolphin kaufen. Seit 3 Jahren fahren wir einen VW Golf 8 Plug in Hybrid. Der fährt sehr gut, aber das häufige Laden ist lästig bei dem kleinen Akku. Der BYD kann ja auch V2L, Du hast ja ein Video darüber gemacht. Und die BYD haben langlebige FTP-Akkus, bekommen wir durch viel Fahren nie kaputt. Und sicherer als ein NMC ist der LFP allemal. Hier gibt es nur wenige BYD, und das technische Wissen darüber ist sehr rah. Deshalb freue ich mich, einen technikversierten Menschen wie Dich, der sich mit der BYD Technik gut auskennt, gefunden zuhaben. Es hört sich an, als wärest Du mit dem Auto sehr zufrieden, das ist für mich ein gutes Zeichen. Ich schaue mir Deine Videos gern an, Du hast eine ruhige, verlässliche Art, die Dinge zu erklären. Mach bitte weiter so👍. Gruß Ulli

Thank you for taking the time to comment. I was in Germany in 2007 and was impressed with all the solar panels I saw as I traveled by train through the countryside. In 2007 Australia had hardly any renewable energy, but in the last 10 years it has grown hugely, and now in South Australia we reach nearly 100% wind and solar often in the middle of the day. It's great to see. My sister has bought a BYD Dolphin and she loves it. She knows a lot more about electric cars than me and has converted a car to electric in the past. I plan to do a video with her soon. So look out for that one.

[@ullischnulli9614]

Great, then you know Europe too😀. In Germany, electricity generation from renewable energies rose to 56 percent in 2023 and we often have overproduction and a lack of storage. A video about your sister's Dolphin would be great. I would also be interested in the consumption and range. BYD only states 7 km more range for the WLTP than for the Atto 3. That can't be true. How are your maintenance costs? In Germany 1st year approx. 400, 2nd year approx. 780 €. I think BYD is crazy. Maybe independent workshops are a solution. The guarantee remains intact. BYD does a lot of things really well with its cars, but there is no usual consumption overview of the last trips. There was enough time to program it, so what does BYD want to hide, what do you think about it?

[@EVswitch]

@@ullischnulli9614 that seems very high for maintenance. Here the average is under $300 per year. Although I got my first one complementary.

[@EVswitch]

@@ullischnulli9614 I think there is a way to reset the consumption graph. And it also can show your average consumption for the last 50km on the small screen.

[@ullischnulli9614]

​@@EVswitch Resetting is good. That's enough too. Thanks.👍

We use say 5 to 10 kWh per day unless tripping. So if I follow correctly, if not concerned about GOM accuracy, the best recharging practice for our Atto 3 is at up to 32 amps in the range 40% to 60% and only to 100% pre lon0ger trips and

[@EVswitch]

Yes, I think you'd be fine doing that. However (disclaimer) BYD recommend charging to 100% once a week. Personally I get my SOC up to 100% once every 2 to 3 weeks. The LFP battery in the atto3 is far more forgiving charging to 100% than a NMC battery, so I wouldn't be too concerned charging to 100% more often. Just don't leaving it sitting on 100% for days.

[@aamir122a]

I am charging at 32 Amps at home on Atto 3 extended , do you think it is too much , should I be charging at 16 Amps for better battery life . FYI unless an emergency do not intend to use fast DC chargers.

[@EVswitch]

32 amps is fine. Any type2 charging is best for battery life. I just charge on 15amps because cheaper for my circumstances.
