The owner has a Tata Punch EV Long Range, which comes powered with a 40 kWh battery pack. The owner plugged its car for an overnight charging session from 0% to 100% SOC. However, it is important to note that it is not necessary that a 40 kWh battery will consume 40 units of electricity.

Due to wiring resistance and natural heat dissipation (also called as Charging Loss), it actually takes around 45 units of power from the home grid to reach a full charge. Let’s assume an average domestic electricity rate of Rs 8 per unit, which is a standard rate across major Indian cities, which makes the maths incredibly simple.
Home Full-Charge Cost of Punch EV: 45 Units * Rs 8/Unit = Rs 360
Thus leaving the Punch EV charged overnight, in the morning you are greeted with a fully charged Punch EV which will provide you a real-world range between 260-270 Km in mixed driving conditions with the AC continually on.
This results in a running cost of around Rs 1.35 to Rs 1.40 per Km. If you compare with a similar-sized petrol SUV that easily costs at Rs 7 per Km, the monthly savings are massive.
Key Details from the Owner’s Charging Session
| Metric | Real-World Data |
| Battery Capacity | 40 kWh (Long Range Model) |
| Grids Consumed | 45 Units (Includes 10% Charging Loss) |
| Electricity Cost | Rs 8 / Unit (Average Domestic Rate) |
| Exact Full Charge Cost | Rs 360 for 0-100% |
| Real-World Range | 260-270 Km |
| Running Cost Per Km | Rs 1.35 / Km |
| Overnight Charging Time | 14 to 15 Hours via Standard 15A Socket |
Why Overnight Home Charging is the Ultimate Hack?
Standard 15A Socket: For many EV owners, the range anxiety is eradicated once you establish a proper home charging routine. By plugging your car into a standard 15A socket at night means it slowly and safely charges your car’s battery cells over 14 to 15 hours, while you are asleep.
7.2 kW Wallbox Unit: If you choose to upgrade to your Tata’s 7.2 kW AC fast wallbox charger, the charging time is massively reduced to just 5 hours 18 minutes.
The Verdict
Ultimately, this will help you to skip the expensive public DC fast charging which often costs you at an estimated cost of Rs 18- 25 / Unit. Thus relying on your residential grid is profitable for you over a longer period of time in order to maximise your long-term financial benefits of owning the 2026 Tata Punch EV.
