Even though the Nexon EV features a locally-sourced battery pack, the Curvv EV will get its battery pack from a Chinese supplier, a first for any Tata passenger car
Tata Motors uses locally-soured battery packs made by Tata AutoComp Systems for the Nexon EV. This has been the case ever since the SUV’s launch in 2020. Now, though, things will change a bit with the Curvv EV. To avoid relying on just one supplier, they decided to get batteries from different companies. For the new Curvv EV, they chose to use battery packs from a Chinese company called Octillion Power Systems.
Chinese Octillion Battery for MR Variant of Tata Curvv EV
According to a report from EconomicTimes, Tata Motors will now get batteries from China’s Octillion Power Systems. Before this, Tata used to source EV batteries locally from Tata AutoComp Systems, which used cells from China’s Gotion. While many people liked the LFP-based technology in Tata’s EV batteries, some issues were reported, like sudden drops in charge and HV errors. Tata decided to switch suppliers to fix these problems. They also want to work with different suppliers to avoid supply chain problems and stay competitive in the market.
Interestingly, the smaller 45 kWh battery in the MR versions of the Curvv EV uses battery packs from Octillion. These packs have 15.2 Ah cylindrical cells from a Chinese company called EVE. However, the bigger 55 kWh battery in the Curvv EV still gets its power from Tata AutoComp Systems, which uses 105 Ah prismatic cells from Gotion. Octillion Power Systems provides Tata Motors with battery packs from its facility in India, which can produce up to 2 GWh.

It’s hard for any carmaker to avoid using parts from China in their cars. China is a big leader in making electric vehicle parts and batteries. They have advanced technology that many companies need to use. This is exactly why it’s near-impossible for any carmaker in any part of the world to not rely on Chinese suppliers. Even if a carmaker tries hard to limit use of Chinese technology, it will still be dependent on Chinese suppliers for many critical components. This simply goes on to the advancement China has made in the global electric car industry. All in all, Tata’s decision to source the 45 kWh battery from China’s Octillion could be a step in the right direction as it will likely put an end to niggling issues faced with locally-sourced batteries.
