Tata Motors Ltd has collaborated with Octillion Power Systems, a Chinese battery pack producer, to expand its battery sourcing for electric vehicles (EVs), according to a report.
The update emphasizes how Tata Motors no longer exclusively purchases battery packs from Tata AutoComp Systems Ltd., its parent company.
For the company’s new Curvv coupe SUV, Octillion, a California-based company with operations in both the US and India, will provide lithium-ion battery packs. For the first time since the 2020 Nexon EV launch, Tata Motors is collaborating with an outside battery supplier.
The update is reportedly in reply to the drawbacks of the EV market and presentation concerns, involving battery discharge descending in former models. Tata Motors is working on fresh designs and hybrid battery pack types in an effort to increase the dependability of its electric vehicles. Additionally, by working with Octillion, they can get new information and raw materials to provide more EVs.
In Pune, India, Octillion inaugurated a 2GWh battery pack manufacturing facility last year. Tata Motors has chosen battery packs from Octillion, which feature 15.2Ah cylindrical cells acquired from another Chinese business called EVE, for the 45kWh edition of the Curvv EV.
Tata AutoComp battery packs, which comprise 105Ah prismatic cells from Gotion, a Chinese lithium-ion cell manufacturer, will continue to power the larger 55kWh Curvv EV. Up until recently, Tata Motors’ passenger EV battery packs were merely produced by Tata AutoComp Systems using cells from Gotion via a joint venture.
The specific needs of the battery pack—such as energy density, thermal management, and flexible packaging—will dictate whether to use cylindrical or prismatic cells.
The company is employing a multi-sourcing strategy, according to a study, to reduce supply chain risks and reliance on a single supplier, resulting in a reliable and timely supply of parts. The remarkable growth of EV sales—which went from approximately 6,000 units in FY21 to nearly 100,000 units in FY24—was also highlighted in the study.
