Tata is introducing a new electric vehicle (EV) architecture called Acti.EV, set to debut on the upcoming Punch EV and subsequently used in various Tata EVs and SUVs, including the Curvv EV, Sierra EV, and Harrier EV. This architecture is distinct from the Premium Pure EV architecture shared with JLR and aims to be the foundation for Tata’s future EV lineup, featuring two different pure EV architectures to develop a portfolio of 10 EVs.
The Acti.EV platform is designed to accommodate different battery types, such as cylindrical or prismatic, including LFP batteries for optimal performance in various climates. It offers a range of 300-600 kilometers and supports charging with an 11kW AC charger or a 150kW DC charger. The architecture allows for front-wheel drive, rear-wheel drive, or four-wheel drive, with a voltage of 400 volts and power outputs ranging from 80hp to 230hp.
Additionally, the Acti.EV platform features vehicle-to-vehicle (V2V) and vehicle-to-load (V2L) charging capabilities, enhancing flexibility and utility. The architecture prioritizes safety, aiming for a 5-star crash test rating, with a crash structure designed to protect the battery in side and pole impact tests using a high percentage of Ultra High Strength Steel. The cars will have efficient packaging, a flat floor for increased space efficiency, and a front boot. Ground clearance has been considered for challenging road conditions.
The electrical architecture incorporates 5G connectivity for over-the-air updates and cloud computing. The digital cockpit experience is powered by Qualcomm Snapdragon processors, allowing compatibility with third-party apps and services. Some models will include Level 2 autonomous driver tech, with plans for Level 2+ in the future.
