Hello Everyone!

Updating the thread, the Relux team had come and installed the 7 kW charger yesterday. I was not present at home during the time of installation and since we had discussed regarding the placement of the charger, they had come and installed it off. As with other brands, the EV charger was supplied with 10 meters of 10 sq mm 3 core copper cable.

Attaching an image of the final look. I might not continue using the gun holder on the wall in the future, only time will tell.

And also regarding the various colours the ring has and the specifications of the charger.

One has to just switch on the MCB and connect the charger to the vehicle, and it automatically starts charging. A RFID card was supplied (It looks similar to the ones you get at hotels, a plain white card without any branding or design), but at present there is no use for it. One can speculate the device also has WiFi capabilities and can be used with the BYD app, but I have no information regarding this as of now.

The messages on the device at the time of charging.

And the information displayed on the driver console screen.

It looks like the charger is charging at 6.38 kW, while the car is receiving 5.7 kW. I am not sure whether this is how it is supposed to charge, other EV owners can comment. On other forums, they have mentioned that usually they get similar findings.

Also, the emergency stop button is located on the top left hand side of the charger under a plexi-glass cover. Once you hit it, you would have to twist it clockwise to release it, otherwise the emergency stop stays engaged.

I must add that in my house, the distance from the main meter box (not the service pole) to my house is around 100 meters and that we have pulled a 10 sq mm 4 core copper cable for this distance and put an 4 pole isolator and grounded the same. I will share details in the relevant thread. I missed reading the forum properly and came to know at a later date, after the laying of the cable that a 16 sq mm cable would have been better in my use case.

Also, in my earlier post, I had missed adding photos of the portable charger (I am not 100% sure whether I should be calling it a 3 kW charger). Also adding a pdf of the manual of the portable charger.

The entire setup.

The head of the gun.

Literature on the back of the charger.

Is sun film legal in India? Any particular thing to keep in mind while installing?

Hi rkgi10,

Thank you.

I might be going a little off-topic in answering your query.

So, I am currently based in Kerala, and recently the Kerala High Court has allowed the use of sun films upto a certain limit, i.e. 70% visibility for the front and rear windshields and 50% visibility for the side windows.

Here is the link for the discussion of the same topic. Link (Kerala High Court interprets use of sun film legal, as per new norms)

There are plenty of threads, posts and discussions on the forum regarding the legality of sun film use in India. Posting a link (Car tints banned by HC! EDIT: Supreme Court bans all kinds of sunfilms in cars)to the same.

There are other threads where people have put better sun films on their cars. Link1 (Why I spent Rs 40,000 on Sunfilm at Speedfreaks, Chennai)& Link2

If one does not prefer sun films, there is a thread on legal alternatives to sun film. Link (Legal Alternatives to Sun Film)

Personally, I do not like sun films to be very frank, especially the dark ones, where the VLT < 50%. I drive around a lot and many a times I am unable to find a shaded parking for my car. Over time this has taken a toll on the interior and the leather upholstery in my previous car. The above reason and the energy required for the battery in the EV made me go forward with sun film with this car.

Regarding the legality, its a grey area. Most of the times, if your sun film does not obstruct vision it is alright, but again it depends on the constable who catches you and the time of year. My previous car, a Honda City has sun film with 20% VLT installed only on the side windows and the rear windshield and I have travelled most of South India with it. I was only stopped earlier when I had the removable mesh sunshades, and of course for document/election duty checking. Nowadays, most police officers have a transmission of light checker to check the visibility; I have seen those in use in Bangalore City, and I have heard that in Kerala they are planning to supply the same device to the police here.

I hope the information helps.

I got a good rate for installing the sun films, total cost of films and installation were within Rs. 20K. I shall DM you the final amount I paid.

The MRP for Garware Artic Cool Shield is about Rs. 7800/- per roll and the Atto 3 used about 3 rolls of sun film for the front and rear windshields and the side windows. They used architectural window film for the moonroof glass, which was quite dark, VLT maybe 30% or less.

This is due to the fact that the wall box unit is showing the AC kWh reading, while the car is showing the DC kWh reading entering the battery. So the losses are due to AC to DC conversion, other electronics in the car is consuming power like coolant pump or in this case the heat pump, VCU, DC-DC for charging the lead acid battery etc.

Hi..
Congrats on your new car.

I would like to know about the 3.3 kw charger.
If it takes 30 hours to charge fully,that means the charging speed will be 3% per hour( approximately).
That means an overnight charging of 12 hours will give you around 36% charge. That is less, compared to my MG ZS EV which charges at 4% per hour and gives a 48% charge over 12 hours.

The facelift variants of Atto3 does not come with 3.3 kw charging cable and we have to buy it as an accessory( around 25k).
If the charging speeds are slow, I was wondering whether it wouldnt be better to get a 3rd party cable.
Anybody using 3rd party charging cables for their cars?

Also, has anybody used the cables interchangeably?
One car company's cable for another car.
Ideally, it should be seamless without any issues.

I recently bought a portable charger from Zevpoint and it can switch between 10A and 16A. Also comes with 2 year warranty. Instead of getting from Amazon you can buy from them directly for a better price. Once I receive it, I will post more details.

That's the important updates that I wish to share. Will update the thread as per any interesting discoveries/events. Would be happy to answer any queries.

Congratulations to a fellow ATTO3 owner. Are there any whatsapp groups we can join? I have a ton of questions about my ATTO3 especially around mileage and would love to catch up.

For instance, at 100% charge, my ATTO3 says the range is 514KM (in dynamic mode) but inside the city that's a gross over estimation. I get about 350-360 KMs in city but was able to clock 450 on the highway with 4 adults in the car and the AC running on 4 and 23 degrees (that an estimation because I got to 410KMs with 9% charge left and display estimating 50 Kms left)

I am curious to know what other owners are seeing in terms of mileage.

I share your pain in terms of AC cooling down the car, it feels like my Ertiga did a better job. I sometimes wonder if it is because of the sun roof and the extra slant on the windshield in the ATTO3 compared to the Ertiga

[Contrapunto]

My wife was keen on the Atto3 and I had gone down to the local showroom for a chat and "another look". The lack of a spare wheel is a real bummer. There is actually a wheel well engineered under the boot...all it needs is a donut tire set and a fixure to hold it together. Even for love and (extra) money you can't buy even an extra alloy even (if you want to make you own option).

I asked what happens my alloy cracks, a not unforeseen eventuality. His response was "you need to make an accident claim, and then I will indent it".......holy moly, you are looking at maybe a couple of weeks of the car sitting idle somewhere.

If BYD is keen on expanding the market, they really need to look more deeply into these issues. As I have said in other posts in other threads, I "salute" all the brave souls to drive around in all hours of the day and night and on highways with nary a thought of sidewall puncture etc. I am not that "brave".

..........

I took the plunge and have not regretted it. The car drives like a dream. sports mode begets a grin I am unable to wipe off even today after 6 months of ownership. Some pain points include the AC and the over confident range display, but I have come to terms with understanding the range and roughly calculating balance. I am also a pollution hater, so I love it that I am not messing up the air any more (Notice I said air and not the environment, I know that the best way to save the environment is not to buy anything illogical like a second car)

As for the tyres, I have never had to change out the spare in my other cars because of a cracked alloy touch wood, I drive around the ATTO3 with a tyre inflator and fingers crossed hopefully that is good enough

Thanks a ton. This looks totally doable. The SA just called me to say that , like the MG Windsor, they will start selling a spare tire kit as an accessory soon- but he was not quite sure when.

The Pune dealer told me their service center would help install the spare tyre. He actually told me that it's part of their accessory.

I have yet to get the car delivered, but the spare tyre is something that I will be installing during my first service center visit.

Hello Everyone!

At the outset, I would like to thank the moderators for pinning my post onto the homepage and newsletter.

Hello sushanthys,

Thank you.

I remember reading earlier in the thread that the dealership/BYD company will provide the portable charger for the early bird bookings for the facelift model. Did they change this?

I have not experimented with the battery level percentage to charging time ratio yet; but I do remember at one point, I had 27% charge remaining and I had put the car for charge with slow charging around 5pm or so. The estimated time required was around 25.5 hours. I had checked in the morning around 7-8am and saw that the charge level was around 65%.

My earlier point regarding BYD reducing the charging amperes was from this post. Link

Another interesting point is that the LFP cells of the BYD Atto 3 auto-balance themselves once the charge reaches 100%.

Sharing an interesting video of BYD battery management which I saw some time back.

https://youtu.be/Wa8PMZ_nw4I?si=WzMdh4g3TgRyT95i

I personally do not have any experience with the other brands portable chargers, but I will definitely consider getting the Zevpoint 16A charger within the next one year. As of now will continue with the 7.2kW charger.

Also, I think you might be able to continue with the charger which you had received with the MG ZS EV as up till earlier this year, BYD was using the services of Echargebays and the Exicom charger was supplied. I think in the dealership for charging of display vehicles they have the same Exicom charger and not the new Relux unit.

Hello DIY410.

Thank you for the insight. I kind of figured there would be some electrical loses, but thank you detailing where all the loses happen.

Hello chavan77,

Thank you.

I am so far not aware of any whatsapp groups for BYD or BYD Atto 3 owners till date.

Regarding range, I have just crossed a little over 1250 kms as of today, and I am still on the learning curve of driving an EV. I still use my previous car for long highway drives as of now.

Regarding the AC, yes, I too found it ineffective especially in the peak afternoon sun. Hence, I had gotten sun films installed. Earlier posts detail the same. The cabin now cools within 2-3 minutes on a hot and sunny afternoon, with the temperature on the instrument cluster hovering between 33 to 35 degrees celsius.

Hi Contrapunto,

The dealership had mentioned that BYD does offer a spare wheel set for the Atto 3, for a cost of around Rs.14,000 approx. At the time of my purchase, they did not have it in stock.

The sales advisor just said what he has been trained to say.

Just for general information and completion sake, I wanted to add a video from Malaysia, where they compared different after-market alloys and the stock alloys of the BYD Atto 3 with a comparison of the different weights of each alloy and the overall look on the car.

https://youtu.be/wxZeVuUMb4o?si=K9Cbw9t0LWla1E8q

It is only a matter of time till people start swapping alloys and tyres in India, followed by body-kits for the BYD Atto 3 in India. Till then, keep an eye out on OLX for people selling off their original stock BYD Atto 3 alloys (in both 17 inch and 18 inch sizes).

[thejaguar]

I just got an update from my RM. He claims that the reason for delayed deliveries is due to the Indian government's mandate that Byd should use Indian tires instead of Chinese tires (in addition to high demand). He indicated that Byd is now working with MRF, Ceat and Good Year for the Atto 3. Seal will continue to have Continental, but Atto 3 will not get Continental.

Again, I am not how true this is, so will be good to hear if other dealers are also reporting similar updates.

Actually Good Year is an American firm. From that perspective, Good year and Continental, both should have been fine. Given that Continental is Indian manufactured too.

I just did a test-drive today. My SA flat out told me, “Sir the Pune dealer is lying, there is no such SKU”. Not sure what the truth is, I strongly recommend that you hold on to his promise and get it fitted. As for myself, I am in quite a dilemma. I asked my Tyre dealer - he shared that a ready made single alloy/ steel will be difficult to find since it’s not a “common size” I just keep scratching my head on why simple things should be so difficult in Bangalore…..I have seen this in many aspects of daily life but that OT for this thread.

Can you please share an update? I am almost at the point of signing up. Some more insights from a long-term user would be of great help. Your experiences over the long term is very relevant indeed.
