I was contacted by the company for this. A technician came to my place, opened the box and replaced a small, thin cable with a thicker one.

Upgrade for 7.2KW Exicom chargers for TATA EVs
There is a free upgrade for all the 7.2KW chargers installed by Exicom for all Tata EVs. According to the technician, there is a hardware upgrade to the 7.2KW Fast Chargers installed for all the opted customers.
I received a message about the upgrade and messaged them the date but there was no reply. Two days back a lady called up and fixed an appointment for today.
The technician called and arrived at my house. He told me that the new upgrade is to increase the charging speed from 30KW to 50KW to enable faster charging and a shorter charging time. It is a mix of hardware and software upgrades that will speed up the charging time.
He opened the box and changed a small cable, a thin one with a thicker one, that would upgrade the speed to 50KW.
Thicker cable
Thinner cable
He then opened an app, scanned the QR code on the side of the charger and installed the upgrade and said it is good to go. But he did warn that some of them didn’t work and he may need to re-install if it gets corrupted. He did cross-check certain parameters and said it is successfully updated. Now I need to see how it works in my next charging cycle.
Here’s what BHPian Comrade replied:
The technician probably did not know the reason behind the upgrade! 30kW or 50kW does not even make sense when charger is rated for 7.2kW. My guess is this could be a recall to replace an inadequate part with a part rated for 7.2kW. Even the initial whatsapp screenshot talks about longevity.
Here’s what BHPian Shreyans_Jain replied:
This is a 7kw AC charger, which is the maximum AC charging that the hardware on the car supports. There is no question of any 30kw or upgrade to 50kw business. This seems to be a recall for the charger to fix a part or cable found to be faulty or underspecced.
I have not received any messages or calls from Exicom as yet, I have the same charger installed at home.
Here’s what BHPian thomahawk replied:
Was it an upgrade from 3kW to 5kW (perhaps the slowest rate was 3kW before?). Does Tata have an app which shows the draw etc.?
