Tata Motors and Octillion Power Systems have recently formed a strategic agreement on procurement of EV battery systems for Tata Motors’ electric vehicles. This collaboration represents a significant shift in Tata Motors’ battery sourcing strategy, marking a departure from its previous practice of exclusively sourcing EV batteries from Tata AutoComp Systems, its group company.
Under this agreement, Tata Motors has incorporated Octillion-sourced lithium-ion battery packs into its newly launched Curvv electric vehicle model, marking the first instance of Tata Motors engaging an external battery supplier since the launch of its Nexon EV in 2020. The adoption of Octillion’s battery packs is viewed as a step towards addressing performance issues of its electric vehicles.
Octillion Power Systems has established a 2GWh battery pack production facility in Pune, India, to support manufacturing operations. The battery packs for Tata Motors’ Curvv EV comprise 15.2Ah cylindrical cells supplied by EVE, a Chinese company, demonstrating the collaborative nature of the partnership between Tata Motors and Octillion Power Systems.
Octillion Power Systems manufactures EV battery systems for a wide range of electric vehicles. Its Bipolar Encapsulated Structure Technology (BEST), is designed to prevent the propagation of thermal runaway in a battery cell, thereby enhancing the overall safety of the battery systems. Octillion’s EV batteries is based on their multifunctional unitized structure technology (MUST). The MUST technology, initially designed for LFP prismatic battery cells, enables significant cost reduction and higher space utilization compared to industry averages.
Not much is available in public domain about the other automakers using Octillion battery technology for their EVs. It looks like it is going to be partnership where both- Tata Motors and Octillion will look forward to setting a benchmark.
