Tata Punch EV Real-world Fast Charging Test: This Is How Long It Takes

We carried out the charging check on the long-range variant of the Tata Punch EV, which is supplied with a 35 kWh battery pack

Tata Punch EV

The Tata Punch EV was launched in January 2024 as the primary electrical providing based mostly on Tata’s new Acti.ev structure. It comes with two battery pack choices – 25 kWh and 35 kWh – with claimed ranges of 315 km and 421 km respectively. Recently, we had the long-range variant (35 kWh) of the Punch EV with us, and we carried out a real-world charging check to see how lengthy it will take to high up the battery from empty.

Charger Used

While the long-range variant of the Tata Punch EV helps as much as 50 kW DC quick charging, we examined it at a 120 kW charging station. It’s necessary to notice that the EV will solely cost on the charging velocity for which it’s rated or designed. Here’s the results of the charging check:

Key Takeaways

  • We plugged within the Tata Punch EV when it was at 0 p.c state of cost (SOC) as indicated on the digital driver’s show. Initially, the charging charge was 18 kW for the primary 5 p.c, then it elevated to 25 kW. The Punch EV continued to cost at this charge till it reached 95 p.c.

  • The charger was disconnected at 95 p.c SOC. It took the Punch EV a complete of 78 minutes to cost from 1 p.c to 95 p.c, i.e., greater than 1 hour.

  • After reaching 95 p.c, the charging charge dropped once more to 18 kW, and it was prone to drop additional for the final 5 p.c of charging and was anticipated to take round 15 to twenty minutes. 

  • Taking all the things into consideration, we count on the full charging time to cost the Punch EV from 1 to one hundred pc to be greater than 1.5 hours.

  • For reference, the claimed charging time for the long-range variant of the Punch EV (from 10 to 80 p.c) utilizing the DC quick charger is 56 minutes. In our charging check, it took the identical period of time to succeed in 80 p.c from 10 p.c SOC.

Disclaimer: The charging time might fluctuate relying on automobile situation, ambient temperatures and move charge from the chargers.

Why Is Charging Speed Reduced?

Tata Punch EV

The major cause charging velocity reduces for many EVs after reaching 80 or 90 p.c is as a result of the battery pack begins to warmth up, which isn’t good for the battery’s well being. To stop overheating and harm, the charging velocity decreases because the EV reaches a better state of cost. This is probably why EV-makers will advocate you to maintain the automotive’s SOC within the optimum vary of 10 to 90 p.c, and keep away from letting the battery drain to 0 p.c or all the time charging it to a full one hundred pc. Some EVs, like smartphones, even have a setting that means that you can management what battery stage the EV ought to cease charging when plugged in in a single day.

Is It Worth Driving Without AC For More Fuel Efficiency? Find Out Here


We conducted 3 tests with the Toyota Glanza, the rebadged Maruti Baleno: AC on windows up, AC off windows down, and AC off windows up

Toyota Glanza

Fuel efficiency is a top priority for Indian car buyers, especially when cruising on highways at normal speeds. However, some people believe that turning off the AC and rolling down the windows can further improve their car’s mileage. To test this, we conducted our own experiments.

Parameters

We used the Toyota Glanza, the cross-badged version of the popular Maruti Baleno hatchback, for these tests. It is equipped with a 1.2-litre petrol engine (90PS/113Nm) and a 5-speed manual transmission. We fueled the Glanza to the brim before conducting 3 tests, each covering a distance of 81km at an average speed of 100kmph. We refueled the car after each test.

Here are the results:

In the first test, with the AC set at 24 degrees Celsius and the fan speed at two, the Toyota Glanza consumed 3.74 litres of petrol while covering 81km on the expressway. This resulted in a calculated fuel efficiency of 21.66kmpl. Next, we repeated the process with the AC turned off.

In the second test, we turned off the AC and rolled down both front windows, assuming that this would increase the car’s mileage. However, with the AC off and windows down, the Toyota Glanza actually achieved lower efficiency compared to the AC-on test.

Why did turning off the AC reduce the mileage? The answer lies in aerodynamic drag. When driving on the highway at high speeds, the car has to counter the air resistance. Opening the windows allows air to enter the cabin, creating drag and affecting the car’s performance. To maintain speed, the engine has to work harder and consume more fuel. Therefore, driving with the AC off and windows down actually reduces fuel efficiency.

On the other hand, at lower speeds within the city, the impact of aerodynamic drag is minimal, so turning off the AC and keeping the windows down can improve fuel efficiency. However, this is not the case during highway cruising. But what if we turn off the AC and keep the windows up?

In our third test, we turned off the AC, kept the windows up, and set the blower speed to two for occupant comfort. By eliminating the aerodynamic drag caused by open windows, the engine had to work less, resulting in the best fuel efficiency of 23.47kmpl.

Verdict

Toyota Glanza

Based on our results, it is clear that driving with the AC off and windows down does not significantly save fuel during highway drives. In fact, it can even result in higher fuel consumption. Therefore, it is better to keep the AC on and windows up for a comfortable driving experience. However, in the city with lower speeds and less aerodynamic drag, turning off the AC and keeping the windows down can improve fuel efficiency. Keep in mind that this technique is most effective in cooler weather conditions and should not be used in high temperatures, as it may affect driver attentiveness during the journey.
