Wow!! That is a very exhaustive write up! I knew practically nothing about the charging infrastructure required for home charging. The way you have explained the whole procedure is praise worthy. Thank you very much and enjoy your new EV

Thanks for a lovely write up. So, does the sanctioned load always have to be upped by the amount that the charger needs? If I have 15KVA sanctioned load and want to add a 11KW charger, will I have to go to 26 sanctioned load? In Bangalore if you cross 25 they ask you to have a transformer in your premises.

Not necessary, but provided you have an electrician who knows what's he doing. You likely need to just add the capacity after accounting for unused capacity. But a new dedicated meter will make it better anyway - monthly average cost per unit savings and simpler load planning.

In my experience, they tested the situation thoroughly. Got us to switch on all geysers and ACs and tested for load. Then confirmed one of the 3 phases have sufficient capacity to add my single phase 7.2 KW charger without requesting an increase in sactioned load. It was a professional team from Mahindra Powerol and had to do a detailed documentation even before they could alot my car or start wiring.

Just came across this video by YouTube Gagan Choudhary about installing an EV charger at home.

Exicom has started directly selling these to consumers: SPIN Home Chargers. 7.5 KW AC Charger.

Currently, the wall chargers are being supplied free of cost by the car companies.
Installation is also free.
The only cost comes from upgrading the electricity load at home.
But when companies start charging for these services( will start in the near future), these direct selling options will find a better market

Small question on the Exicom Chargers that are being installed which comes free with the Car.
What do we do in case of power cuts?

say I set charging (after plugging in and scanning the RFID) and in the middle of the night power goes.

Will the charging reset and I have to wake up and go and scan the machine again?
The vehicle in question is the New Nexon EV

[ghodlur]

To all EV owner who have got the charging setup done at their homes (an in high rise complexes):

1. What are the safety controls in place during the EV charging? Does anyone keep a Fire extinguisher nearby?
2. In High rises, what precautions should an EV owner take when installing the EV charging set up in the parking slot where 2 cars are parked? Has anyone checked if the next car owner is comfortable with the EV charging set up or Society permission is sufficient and its Society's headache to look after the safety part?

Reason for asking above queries is the parking slot neighbor in the society basement parking next to my parking is asking for a go ahead from me as well.

The charging resumes once the power comes back.No need to reinitiate charging

Regarding point 1, if you have obeyed all criteria before installing a fast charger, it is safe.
The chance of a fire is not any higher than the existing fire risk at your house.

Regarding point 2, cant comment since I stay in an independent house

The second time, I ended up charging the car to 100% (wanted to stop at 95% but app issues meant I could not disconnect in time). In the first 5 km of travel after charging, I lost 5%. After that, the battery behaved normally. I checked with MG during my first service regarding this matter. They said that when DC Fast charging is done, all cells may not get equally and completely topped up, hence a bit of sudden battery discharge is common. This problem does not happen with slow charging/AC Fast charging.

Dear Dr Sushanth, Thank you so much for this hugely informative write up. We got our ZS EV in December 2023 and since then this thread of yours has been my bible for all charging related doubts. I had initially thought of installing the wall charger but after going through your post I have so far decided to do slow charging using the portable charger. Once in a week we have been using the GO EC fast charger at the Ettumanoor area, so if you see a black ZS excite parked there with KL36 plates, it could be us

I have also recently noticed this unexpected fall in SOC after fast charging. My wife was horrified seeing the SOC dropping by 28% after her round trip to work and back (which usually takes just about 20-21%). I am hoping your explanation will calm her down.
Thank you once again for sharing your experience and please keep this thread going on.

Hi Night Raven,

Thank you.

I travel by that GO EC Fast charger 3-4 times a week, so will surely keep an eye out

Its been almost a year since I got my ZS EV. Lately, I have been using the wall charger much more. Mostly when I have to charge the car from a SOC in the mid 20s. The charging will get over in around 5 hours compared to > 12hrs with the slow charging. It is also very useful when you have to charge to 100% prior to a long trip. Not a bad idea to have the wall charger installed.

I have noticed that the consumption of charge from 100 to 95% SOC is generally fast. The efficiency will usually be around 5-6 km/kWh.
Maybe also because regen takes place only after SOC drops below 95%.

Hope this helps!

Do you remember the cost for this cable/meter? Is it a 4 core cable? KSEB guys hadn't given proper gauge service line for my 3 phase connection (just a set of two 2.5 sqmm) sighting supply shortage. After pestering them for a long time they asked me to just buy the cable spec I want as they aren't going to be able to provide the right spec for my connected load requirement.

My service line is going to be overhead (can't do under ground as it will require lot of work), so not sure if that matters.

A 4 core cable is only required for large capacity chargers( like 22kw).
I remember the echargebays guys telling me that 4 core is not required.
KSEB guys wont have it .I bought all the required cables.

Overhead service line is not an issue.

Not sure if this might be off topic but is there anyone here who has an EV has not installed charger at home and relies entirely on public charging infrastructure?

Today I saw a post on X regarding a guy having to charge his car for almost 2 years because his housing society is not permitting installation of charger.

I have shortlisted an ev as an option for buying new car (will provide more details in a seperate thread I create for my car choices) however this reason is holding me back.

[linuxworld]

I think the position of law is clear on this topic, and a cooperative society is expected to provide NOC in the stipulated time. However, it's also a fact that societies keep harassing EV buyers just for the sake of having any solid reason. In the worst-case scenario, you can ask for a 16amp socket from your meter, and society should be comfortable with it. I am also in a similar position to yours but confident that the committee will allow it as long as there is space in my parking to install a charger.
