Below is my assumption based on the brochure and information given online so take it with a pinch of salt and cross-verify with actual testing.

I think the dealer is bluffing to push a quick sale. I heard Tata is ”producing” bundled variants currently. All Punch.ev variants (including base Smart MR variant) support 7.2kW and 50K additional is just for the wall charger. Tata DOES NOT downsize AC-DC hardware to 3.3kW if you do not pay 50k and upgrade to ACFC variants.

One way to check is to go to the service center and check for a car without ACFC bundled originally (any MR variant) and test out the 7.2kW charger laying around the dealership.

Nice review.

I went to Tata showroom to checkout Punch iCNG, surprisingly found out that the rear leg space is compromised in electric version of Punch. The petrol version has more legspace and slightly better under thigh support.

Note that 7.2 kw charging invariably means increasing the sanctioned load capacity as no one would have that much excess capacity. For 1,000km a month you need to charge 4 times a month, even if you go down to 10% each time, it can be easily charged overnight.

My opinion differs here. Punch.ev LR takes 14 hours to charge from 10-100 using the 3.3kW charger. That's a bit too much given that it is recommended to discharge below 10% at least once a month.

If you leave for work at 9am and get back home at 6pm, you are neck-to-neck! If you need your car for a quick run in the evening, it won't be available. That's disappointing if EVs have to act as primary vehicles.

Getting the sanctioned load increased is a hassle in most states, no doubt. But it is a one time thing. But once the wall setup is ready, it also saves the effort of unwrapping and wrapping the foldable charger every time.

What I expect from Tata is a portal, which lists all the 7.2kwh chargers that have been installed across the country so that they can be shared. In my street alone, there are 3 chargers. If there is an option to share and monetize, most people would be happy to do so. Some people are already listing their 7.2kW chargers on PlugShare but that can be (and should be) more common than what it is today.

Frankly, the restrictions, that we need to charge in a particular way (below 10 once a month and upto 100 everytime), need to go and EV charging tech has to be as simple as mobile charging. Only then majority would adopt these cars.

The fact that Tata's official brochure states that mid-range (25kWh) cars can be charged in 3.5 hours with ACFC is a testament in itself that cars sold without FCs can be charged using ACFC.

I got my Punch EV LR variant over the weekend. Faced couple of issues until now. Sharing here for others benefit.

1) Traction control got ON inside city probably after a speed breaker or a pothole. The car started behaving weird after that. It went off after switching off the vehicle and switched on again.

2) the gear was not changing to R reverse. The knob turns with a chime and the display did not change. I talked to service advisor and he mentioned to press hard the break pedal before turning the dial. Then it started working. So every time you turn the dial, keep the break pressed hard/full.

regen gets to level one at every start of the car. I am yet to find how to turn it off permanently.

Open the bonet and check the charger capacity, you will see the power rating either in Amps or kW. Check the below link on the team bhp of the actual 3 in 1 unit which is in the charger.
Also attached the drawing.

@aim120 is correct.
The OEM for this is Valeo you can see that it comes in two versions 7.2kw and 4kw.

Why would they sell charger 54K later, if it is not supported in the lower model? Also I see people suggesting to buy 3rd chargers to reduce the cost of buying ACFC Model.

The third party chargers, wall box chargers, portable chargers are not the actual charger.

Below is the actual charger.

Below is the actual charger.

Very useful information . Now wondering the value of the so called chargers from the market as the key AC to DC conversion with the corresponding power draw happens in this unit.

The gentleman in the video below explains the wiring and that this component also charges the 12v Aux battery from main battery. He also explains the coolant flow to this unit.

The Valeo part that Tata is using is confirmed to be a 7.2kw, I checked the internal part number and its a 7.2kW unit even on the 3.3kW model.

How was the iCNG version? You went to see it but commented on the other two

Its one big money making product, the wall box and portable charger is nothing but a plastic box with of RCCB/ELCB, a surge protection (MOV varistor) and a 32A rated relay and a small circuit that allows the pilot signal to On-board AC-DC charger to accept charging, only if earth leakage, short circuit is not present. All this in a fancy plastic mould. The single most expensive part is the 3+2 core copper wire and charge gun.

You are better off buying the aftermarket portable unit with user selectable switch to toggle the power rating, which justs sends a signal to On-Board charger to either limit itself to accept 2.2kW (10A), 3.3kW (16A) and 7.2kw (32A) or for expensive cars with three phase 11kW (16A x3) or 22kW (32A x3) in cars like Ioniq 5.

I was about buy punch EV adventure. Thanks for sharing issues.

Dealership arranged a concall with TATA Motor team where TATA Power employee also joined. They confirmed that Car is compatible with 7.2AC Charger and if in future need arises, they can install it via dealership.

I booked an Adventure LR ACFC with a dealer. He gave a sweet deal but asked to book on the same day. I paid the booking amount and the dealer agreed for a PDI the next day. During PDI, I noticed that the regen levers were not working. I could not change levels using that.

The SA said that a software reinstall would fix it and that they would get it fixed on the next working day at their SC. On that day, I visited the workshop and they said that the car needs a part replacement.

Now I'm in a fix. Should I accept a car with a replaced part? Is handling at the factory and SC drastically different? Given the plug and play nature of parts, does it make a big difference if a part is swapped?

Or should I ask for a new vehicle / refund?
Please advise. Thanks!

You must not take delivery until all issues are fixed and inform the dealer in any more issue crop up in PDI, you will either take a new vehicle or refund. what is the deal amount? approximately?

As far as I am aware, none of the tata dealerships are providing discount on the Punch EV, if they are then it is something to look carefully, because it might be a return vehicle from other customers, can try cross checking that, by checking the manufacture date, and also check using the VIN number, like if it was already registered or something, not sure.
This is just my point of view also if the discounts are on the insurance amount and not the ex showroom price/cash discount, I would not suspect any major issue. Might be they wanted to sell away that colour or model soon.
Good Luck!!
