The Nexon EV charger has no such settings. I suspect even if I source an after market charger that can trickle charge from a 5 amps socket, it may not work for the Nexon. For now I think the most practical approach is to look for 15 amp sockets and perhaps carry a 15 amp extension cord if you cannot get the car close enough to the socket.

Always comfortable for me to have a home ac fast charger. Power supply is unreliable in our locality with frequent power cuts. If the power goes off, then I have to go and restart my charging again. Before I installed my fast charger, it used to take around 12 hours to fully charge my punch ev LR from 30-100%. Now with the 7.2kw charger, it takes less than 5 hours for the same & I am able to complete the charging most of the time before a power cut.

I currently have 2 EV’s in my garage the MG ZS EV and the BYD atto3 I prefer charging both these cars using the 15amps plug I generally plug the car around 40% in my regular usage and the cars are ready in an overnight charge which is peaceful because when I use the 7kv chargers ( I have both the chargers installed because BYD Chennai advised me not to use the mg charger stating it isn’t good for the battery which I really doubt because both are 7kv ) there are voltage fluctuations in the house which is not good for all other electronics and
I find the 15amps more convenient as it does the job and prefer to slow charge as much as possible so I don’t mess up my battery health

Hi, I have sent you a pm. Please check. It will be of great help. Maybe your pm isnt activated. I will send you my number.

Hi,

I have recently got a charging box done for my EV. Drew inspiration from BHPian Mathewanil’s box LINK (Owner's take on the Citroen eC3 Electric)

All the internal components are rated for 40 Amps since price difference between a 20 Amps RCBO & 40 Amps RCBO is not much. Also includes a surge protection device (SPD).

Though I am using only 3.2 Kw charger on the current setup via the socket, i can anytime plug in a 7 Kw charger to the RCBO output in parallel to the socket. I have added a 16 Amp MCB before the box for 3.2 Kw load (because 40 Amps RCBO will be overrated for 3.2 Kw load).

Legrand 12 way box was used. Internal cabling done with 6 Sqmm cables. All end terminations done with Pin type lugs & heat shrink sleeves. DIN mount multimeter was procured from Amazon. It is indeed a very helpful add on to monitor key parameters.

The setup costed me around 10,000.

Do we have to increase the contracted Load with our electricity department for getting this installed? For example, if one has 5kW Contracted load and plans to get 3.2kW or 7.2kW box setup, what would be the charges to get this increased and is it mandatory or not? I am a noob in this and planning to get an EV i near future. Any inputs?

Please check your summer months bills, consider the highest RMD.

If RMD (mentioned in the bill) + EV load < Contracted load, you are good to go.

Provided, the electrical cables carrying power to your distribution board is capable to take the additional load. Your electrician should be able to confirm this.

I presume you are from Telangana, charges to enhance the Contracted Maximum Demand are reasonable & you need to file an online application if enhancement is warranted.

Thank you. MD is showing as 3.6 even for last month, so guess I should get it increased even for installing a regular 3.2kW charger setup (Contracted load is 5).

Let me check with my electrician and will explore the online Application part accordingly.

Hey guys, me EQE came with a 22kWh ABB wall box charger which I got installed in my office.

But I mainly plan to charge it at home with a regular 15/16A socket for in order to elongate battery life. It came with a portable charger as well. Pics attached below. I can ask our society guys to install a regular 15A socket near my parking in the basement. The wallbox installation guy told me it can fit into a 15A regular socket but it needs an industrial 15A socket.

Do I need to buy the entire 15A industrial 15A plug or are there adapters available for the same ? Can someone shed more light onto these 15A industrial sockets?

[Voltzzzzz]

I recently bought the Windsor Essence variant which comes with 7.4kw charger. Unfortunately I am unable to install it due to my parking spot being too far (~100m) from the meter and hence prohibitively expensive cost of installation. Instead now I am planning to get a 16A plug point installed.
Is a 4sqmm wire enough over a length of 100m to connect the plug and the meter for 3.3kw portable charger? Suggestions appreciated.

Yes recently my uncle had brought his New Electric Tata Curv to my home and to check it we had plugged his normal car charger with my 15A socket which I had installed in my portico (I use this plug often for high pressure car washer pumps ) and with almost nearly 2 hour of slow charging its battery level increased by 15% and one can easily charge it during the night and go to bed with peace. More over all EV car manufacturers always suggest slow charging for the good health of the Battery !

Totally agree.
A good old 15A, (preferably with an MCB) is more than enough to charge.
Period.

I had a specific use case and installed a Bolt Earth Pro 4G device in my apartment basement parking slot.
Its just a glorified 15A+MCB with GPRS connectivity

The 4G gives me the flex of :
- starting and stopping charging from anywhere as long as the charger is physically connected.
- monitoring the charging/usage remotely via app
- keep the 15A in my slot free of random misuse



I could have done a regular 15A with traditional lock and key, but decided to splurge a bit. First EV after all

I have a very similar parking in my society as well. Is your Grid connection a 5kw or the regular 3kw? Did the society have any approval process before you could do the wiring? I am presuming you did the wiring from your grid meter from the society basement. Does your basement support sim /4G range to maintain connectivity?

Not sure if you got the reply but 4sqmm is more than sufficient for 15A draw over 100m. If you so desire, you can draw a 6sqmm cable and ask the MG guys to install the 7.4kw charger to that line and run it at about 5kw speed, if possible.

Thank you. I got 6sqmm cable with 16A plug point. It draws ~ 2.6-2.7kw acc to the MG app (image enclosed).
The Exicom people who were supposed to do installation were advising to put 10sqmm wiring. I am no longer interested to spend so much and also increase the load capacity with the electricity board.
The 7.4Kw charger is currently lying with me unused, unopened and I want to sell it off if anyone is interested.
