My electricity bill suggests that the vehicle is using 900 units extra to charge. This is making it almost as expensive to run as a CNG or even some petrol cars!

Hello everyone,
I bought the Tiago EV XT Long Range 2 months ago and have already done about 5500 Kms on the same. As my running was high, I opted for an EV considering the low running costs.
So, my EV charges from a separate three-phase electricity meter which powers the parking of the house and has 8-10 LED lights and the elevator taking load from it. I haven’t changed or added anything to that meter except the EV.
My average driving each day is about 80 Kms and my battery at the end of the day is mostly around 50-55%. So, by that logic, my Tiago EV having a 24kWh battery should use about 12-14 units per day to charge resulting in approx. 400 Units of extra electricity consumed during the month. The car is charged daily and is usually plugged in at 10-11PM and removed from charging at 8-9AM in the morning. Also, I use only the charging box and charger provided and installed by TATA.
Now this month I have got the first bill which reflects the full 30-day charging cycle of my EV and the car is consuming 30+ units per day resulting in 900 Units extra to charge! My bill with the same load used to be around 130-140 units a month and this month with the EV charging is 1039 units.
I am unable to understand how it is consuming so much electricity when it is more than the battery capacity and the battery is almost never below 50%. This is making it almost as expensive to run as a CNG or even some petrol cars!
Can anyone explain what could be wrong and how to go about fixing this?
Here’s what BHPian Shreyans_Jain had to say about the matter:
It is likely that the meter is defective. There is no conceivable other way that so much extra load is being put on a dedicated EV charging connection.
That being said, why did you opt for a separate connection and meter? You already have a tried and tested connection running for your house. Why not just pull a line from that?
Here’s what BHPian mercedised had to say about the matter:
My suggestion would be to get a separate meter installed just for the EV from your local electrician and monitor the usage for another month.
Here’s what BHPian Thilak29 had to say about the matter:
Get a smart plug and use it while charging – it can identify if it is indeed using more units than it should.
In the ZConnect app too there is a way to see how many units were consumed in a month, correlate with that.
Here’s what BHPian ferrarirules had to say about the matter:
This is very surprising but not possible. Either there is something else consuming electricity on the same connection or the meter is defective.
Having said that that unit consumed will always not be exactly the same as what your car capacity is as there are some heat losses of around 5%. My Nexon EV max (40.6 KWH) takes around 43 units of electricity to charge from near zero.
Here’s what BHPian wheelguy had to say about the matter:
Also, do note, it consumes more units to charge from say 0 to 50 than to charge from 50 to 100. Try charging from 10% to 60% if your usage/routine permits.
Anyhow there should be something else also wrong, check for it. Few years back, had a similar issue at my place, despite us consuming less power compared to our neighbors who had more members at home and more ACs and more usage, we are getting electricity bills significantly higher than them.
First checked all devices and wiring at home and then complained to our power distributor APEPDCL, they came and inspected the connection. Few days later they voluntarily changed the meter and the wire coming from the pole to our meter. Then our electricity bills came back to normal.
