The 4th electric car from the house of Tata Motors, the Curvv.ev, is making waves, not just for its coupe design, but also for what’s under the hood. Before technical details came out, it was rumoured that the Curvv EV would feature the same battery as the Nexon EV. But Tata Motors surprised everyone and equipped its new electric car with not just a different capacity battery but one with a different cell structure as well! The new Curvv EV has a distinct battery capacity, cell structure & power rating.
Tata Curvv EV Battery Capacity and Range
The Tata Curvv EV comes in two battery options: a medium range 45 kWh battery variant with a certified range of 502 km & a long range 55 kWh battery variant with a range of 585 km. Prices for the 45 kWh variant start from Rs 17.49 lakh & for the 55 kWh variant start from Rs 19.25 lakh. The Curvv.ev comes with a warranty of 8 years on the battery.
Charging Options, Charging Connectors & Charging Times:
The Tata Curvv EV comes with the industry-standard CCS2 charging port. Owners have 3 charging options: home charging via a 15A home socket, home charging via a 7.2 kW AC wallbox charger and DC fast-charging at public EV charging stations.
How Long Does It Take to Charge the Tata Curvv EV?
With the 7.2 kW AC charger that comes with the Curvv EV, the car can be charged 10-100% in 7.9 hours (55 kWh variant) & 6.5 hours (45 kWh variant). With a DC fast charger, the Curvv EV can be charged 10-80% in 40 minutes.

App Support for EV Charging:
Along with the Curvv EV, Tata Motors also launched the iRA.ev app to support its EV owners. With the Tata Motors iRA.ev app, Curvv EV owners get access to a wide variety of features including live status of around 9000 EV chargers with information regarding type of charger, available charging connectors, charging speed, etc. Apart from being an EV charging aggregator app, the iRA.ev also offers route planning solutions featuring live status of chargers enroute one’s destination.

Curvv EV’s Advanced Charging Tech:
For the first time, Tata Motors has introduced 1.2C charging technology with the Curvv EV, enabling owners to charge their car faster than other Tata electric cars.

1.2C implies that the Curvv EV’s battery can be charged at a rate 1.2 times its capacity. If we take the long range Curvv EV as our subject, its 55 kWh battery can be charged at a speed of 55*1.2, i.e. at a rate of 66 kW. In an EV, the C rating is an indicator of its battery’s charging capacity.

Different electric cars have different capacities for charging. Charging capacities vary among different electric cars and regulate the speed you can charge at. The charging process will be limited to the maximum capacity supported by your EV. If the car has a maximum charging capacity of 50 kW, the EV charging station will automatically ensure that the charging does not exceed 50 kW, even if the charging station is able to do more than that.
The Nexon EV’s charging capacity is 30 kW while the Curvv supports 70 kW. This, along with the bigger battery, could be a game changer for Tata Motors and may label the Curvv EV as the best range mass market passenger EV in India!
The long range 55 kWh battery pack can be charged at a claimed maximum rate of 70 kW while the medium range 45 kWh is capable of a maximum of 60 kW. According to the company, this allows the Curvv EV to gain sufficient charge for a 150 km drive in just 15 minutes!
Curvv EV Battery Cell Structure:
The Tata Curvv EV features prismatic cell structure rather than cylindrical cell structure (found in the Nexon EV).
Thanks to these prismatic cells, Tata Motors was able to increase the battery density, unlike the Nexon EV which uses cylindrical cells. Prismatic cells can be packed in a compact manner, unlike cylindrical cells that leave some voids. This enables an increase in battery capacity. The battery pack looks the same from outside, but the cells inside & the space utilization are different. The prismatic cell structure gives the Curvv EV a better range.
Conclusion:
Recently, Tata Motors has started mentioning a rating called the C75 range. This figure gives a more real-world range as compared to the certified figures which are usually achieved at ideal conditions. The C75 range testing involves factors such as higher temperatures, air-condition usage, etc. The C75 range for the Tata Curvv EV 55 kWh variant is around 400-425 km and for the 45 kWh variant is 330-350 km. Releasing these figures show how confident Tata Motors is with respect to its Curvv EV. Most reviews have given the EV a thumbs up and if you are looking for a new electric car, do test ride the stylish Curvv.
