We had the 55 kWh long range variant of the electric SUV-coupe, which supports DC fast charging of up to 70 kW

The Tata Curvv EV was recently launched as an electric SUV-coupe, which comes with two battery pack options and an ARAI-claimed range of up to 585 km. We recently had the long range variant of this EV, which comes with a 55 kWh battery pack, and we charged it from nought to 100 percent using a DC fast charger. Tata claims that the Curvv EV can be charged from 10 to 80 percent in just 40 minutes, using a 70 kW DC fast charger. So we decided to put it to the test and see how true it stays to the claimed charging times:

State Of Charge	Charging Rate	Time Taken
0-5 percent	65 kW	2 minutes
5-10 percent	62 kW	2 minutes
10-15 percent	56 kW	4 minutes
15-20 percent	56 kW	2 minutes
20-25 percent	56 kW	3 minutes
25-30 percent	58 kW	3 minutes
30-35 percent	59 kW	3 minutes
35-40 percent	47 kW	3 minutes
40-45 percent	47 kW	4 minutes
45-50 percent	47 kW	3 minutes
50-55 percent	47 kW	4 minutes
55-60 percent	47 kW	3 minutes
60-65 percent	47 kW	4 minutes
65-70 percent	47 kW	3 minutes
70-75 percent	48 kW	4 minutes
75-80 percent	48 kW	4 minutes
80-85 percent	48 kW	3 minutes
85-90 percent	24 kW	6 minutes
90-95 percent	18 kW	9 minutes
95-100 percent	8 kW	19 minutes
Total Time Taken		1 hour 28 minutes

Key Takeaways

While the Curvv EV supports DC fast charging of up to 70 kW, the maximum charge it could take was 65 kW, that too during the initial few minutes.
The total time taken to go from 0 to 100 percent was 1 hour 28 minutes, out of which the 10 to 80 percent time was 47 minutes.

The 10-80 percent figure claimed by Tata is 40 minutes, and in real-world conditions it took the Curvv EV 7 more minutes to reach that state of charge.
From 10 to 35 percent, the battery was charging at a rate between 56 kW and 59 kW, and from 35 to 85 percent, it dropped to around 48 kW.

From here on, the rate of charge was cut by half for the next 5 percent, and then it dropped below 20 kW till 90 percent.
During the last 5 percent, the Curvv EV was being charged with a rate between 8 kW and 9 kW.

Battery Pack & Range

Battery Pack	45 kWh	55 kWh
Electric Motor Power	150 PS	167 PS
Electric Motor Torque	215 Nm	215 Nm
ARAI-Claimed Range	502 km	585 km

The Curvv EV is offered with two battery pack options, both of which are paired with a single electric motor that powered the front wheels. The bigger battery pack gets a more powerful motor, and it also offers a higher claimed range.

Note:

When charging an EV, many factors affect the charging time, including the weather, temperature, and battery health.
After the battery pack reaches 80 percent charge, it starts to heat up. To prevent the battery from getting damaged, the charging speed is reduced, which results in a longer charging time from 80 to 100 percent.

Price & Rivals

Tata Curvv EV

Prices of the Tata Curvv EV range from Rs 17.49 lakh to Rs 21.99 lakh (introductory, ex-showroom pan-India), and it is a rival to the MG ZS EV. It can also be considered a more premium alternative to the Tata Nexon EV and Mahindra XUV400.
