I drove the car with 4 persons but not for long. Didn't observe but that's anyway bound to happen. More the load more the power required to pull and hence more juice required.
However, this time I will try to observe the difference in the deterioration but I'm afraid it will happen only after the lockdown.

Hi chandu1382,

Does your Nexon give separate average consumption for each trip meters?

The picture shows an average consumption of 227Wh/km on trip A for 207 Km. That translates to almost 47kWh which is more more than Nexon EVs battery capacity. It just does not add up. The consumption is too high to achive any meaningful range.

In the screenshots shared by our own member chandu1382, the consumption on trip A hovers between 136 Wh/km to 151Wh/km. This translates to a range of 200km to 180km range if 90% percent of its 30kWh capacity is used.

Thanks,
Antony

He had charged the car on the way. So the assumption that 227wh/km is not going to give you 200km is correct. The usage for most people in city hovers around 120wh/km and on highway around 140-160. So ideally we are looking at a range of around 200-240 based on driving style and use of regen. However, a recent news suggest that Tata has an update in pipeline which would futher enhance the range and performance a bit.

Nexon EV (or any decent EV) is ideal for anyone:

1. who lives in a city. EVs are more efficient in city speeds in contrast to ICEVs.

2. has a decent commute (30 km+). Its easier to drive in the city and savings on fuels are significant.

3. and have a place to charge at home or office. We need to drop the discussion around only having to charge every 2-3 days. Charging is something you do every night. You top off to the recommended levels set by manufacturer. There's no reason to not do that. EVs aren't for you if you don't have a place to charge at home or work.

If you aren't sure of getting an electric car, try getting an electric scooter. You'll see how its better all around.

@chandu1382 - Congratulations on your great purchase. Hope you lead the way in showing others how convenient and practical EVs can be.

Had a question on drivability. Which traditional Automatic is the driving experience of the Nexon EV closest to ? CVT /TC /DCT /AMT ? Would it be easier to learn driving an EV as compared to a ICE auto , for someone who has no prior driving experience ?

The average Wh/ km is not separate for the trip meters. It's also dynamic. You drive aggressively for a few moments it shoots up.

Thank you. Yes, I'm explaining everyone I know why it makes sense to buy an EV and why they shouldn't be worried. About comparison with transmission- it's definitely doesn't feel like AMT and TC. May be CVT. Not sure about DCT.

Yes. It'll be easier to learn on an EV for a beginner. But they get spoilt with technology. IMO it's always best to learn on a manual transmission

Is it possible to install a fast charging station at home ? What are the technical difficulties regarding the electric lines? Is it possible with some 10 kv solar set up ?

You can set it up at home if you can afford it and can get the KSEB approvals. Nexon EV accepts upto 25KW fast charging and a 25KW fast charging station costs upwards of 5 lakhs. Then you need a 25+ KW connection from KSEB for which you will have to pay a security deposit of around 1.5L. Add to it the cabling charges where you will need separate cabling from the nearest transformer. If you are unlucky enough, you may even end up setting up a transformer in your compound if the electricity board decides that the their transformer cannot supply the additional demand. On top of that, there will be a fixed fee of ~5K per month in addition to your electricity consumption charges.

5 years ago, I had taken a 40KW connection in Trivandrum and ended up paying close to 5L for all fees, security deposit and cabling. I am paying 6000+ as fixed charge every month even if I don't use the electricity. So unless KSEB has come up with any new consumer friendly policy for EV fast charging, it will not be worth the cost and the hassles.

A 10KW solar cannot provide continuous and stable power to charge an EV. You will have to supplement it with Grid power even if you are planning for a <10KW fast charger (I haven't seen DC fast chargers <15KW. ). And with that, you might end up reducing the charging time just by a few hours.

As Holyghost replied setting up fast chargers is a costly affair, and I am not even sure if the utility will allocate 30kw(25kw for car + 5kw for other use) power to single house.

Yes, you can use the solar power directly to your car but that is not possible with a dumb charger given by Tata along with the car.

You need a smart charger like this which can directly use your solar power.

Not sure any of these kind of smart chargers are sale in India.

25KW or 2.5KW?

25KW at 220V translates to 113Amps. Can a EV can take 113 Amps for charging?

Usually, 3 phase connection can get a sanctioned load upto 12KW . Anything beyond and you need a transformer for your home.

[DarthVeda]

Fast charging is done through DC, for anything up to 25KW, would be having either 48v or 72v with max current drawn at 200A.
for anything above that the voltage goes to and above 700V. I highly doubt, that you can have fast charging setup at home.

Hello everyone,

This is a very interesting thread and I'm really impressed by the product that TATA has delivered.

Does anyone know of the schedule of the Lease/Subscription option that TATA was planning to start for Nexon EV somewhere around April 2020?

I know the current situation might have delayed it a bit, but any ideas on how long? Any pointers would be really helpful.

Thanks!

Hi,

If I want to buy insurance from outside, can someone guide who to contact?

Cannot see Tata nexon ev on acko or policybazaar. Mu assumption is it would be cheaper if I purchase from outside.

Have you talked to the customer representatives of policybazaar and other websites and explained about the situation?
