While I agree with the title of this thread, I would like to mention that getting a 7.2 KW AC charger is a big convenience. My Nexon EV Max takes about 12-14 hrs for charging from 10-100 % SoC where as it takes about 5 hrs 30 minutes on the 7.2 KW charger. This is for a 40 KWH battery. With the new Nexon 45 KWH and EVs with higher capacity like Curve 55 KWH, BE6E and XEV96, it becomes impractical to use only the 3.3 KW trickle chargers.

So do not cheap out on the 7.2 KW charger if you can afford it and also manage the resulting increase in the Electricity load.

The convenience is great, but not everyone can afford it.

Agree but just to add you can get the faster AC charger from external sources as well and often it is cheaper than getting it directly through the OEM (50 K for the Tatas).

I assume it also needs 3 phase electricity. Increasing the load is a lengthy process as well. In KA they also charge 100 Rs per Kw as fixed charges per month. This would itself result in 1000Rs fixed charges if we get a load for 10Kw. For regular charger, a 3Kw Single phase connection would do.

As far as I understand the 7.2 KW charger does not require a 3 phase connection. Even though I have a 3 phase connection, the charger itself is connected to one of the phases (Blue if I recall correctly). You will have to increase the sanctioned load though.

Any reason the OEM portable chargers max out at 2.2 to 2.6kw. If it can perform at the rated 3.3kw we should ideally have slightly better charging times.

I think Anand Kulkarni in one of the interviews had said that they did not go for the full 16 Amps because many of the so called 16 Amps socket installed in Indian cannot actually sustain such currents for long periods and can be a hazard. I think it is a pragmatic decision to not touch the limit.

I am happy to get proper wiring from the meter to my parking. Can I modify the TATA portable charger to take 16A. I know a lot of aftermarket chargers are capable for the full 16A

The 16A socket can sustain about 12A of continous load. While for short duration it can sustain 15A. A EV charger is a continous load.

It doesn't make economic sense to modify the portable charger. After market chargers that are capable of full 16A current use the industrial 16A plug, so it means you will also need a industrial 16A socket. So not a lot of places have that socket vs common 16A Indian socket.

How do you guys charge in hotels? Do you specifically look for hotels with charging options only or do you ask for charging via the portable cable with 15 A socket?

Do hotels mostly acknowledge such requests (for hotels without EV chargers)?

Mods please move this query to appropriate thread if needed.

Hi

Power socket should not be fixed in open area exposed to rain. It may cause short circuit and may trip other lines.

Will also cause electrocution to humans / kids during rain.

If open parking is only available then conceal the power point inside a water proof cabinet

EV selling dealer would be able to help you. They would be having trained electrical contractors for this.

As per the below article, ev chargers can't be installed in basement parking:

https://timesofindia.indiatimes.com/.../117801943.cms

If this is correct it is a big blow to people who stay in apartments and have parking in basement areas. Is there a place where one can find guidelines for this??

Hey, Did you even read the article fully? It mentions that court is not okay with society stopping the NOC, meaning Court asked the society to give NOC and allow the charger installation.

It seems OEM's are not selling portable 15A extension cord circuit with grounding electrode kit, which I feel is a must on a trip. Third party vendors are selling anywhere at ₹12k plus, so showrooms are easily loosing ₹30k (because they sell everything with "genuine" tag & 3 times cost )

What are some good quality extension circuit brands for connecting portable charger to 15a wall socket, during journey wherever improper earthing fails the charging ?
I think the kit shoud be both effective in proper grounding and safe with correct specifications of wires, fuse, etc.

My Kona came with a complimentary 3.3 KW charger with a sufficiently long cable and a 15 Amp 3 pin plug.
I use it at home from time to time. Like plugging in an iPad.
This 3.3 KW charger brings the car from 40% to 100% in about 8 hours.
They also gave me (free) an ABB 7.2 KW charger which I haven't installed.
