India Electric
Global trends strongly indicate a rapid switch over of personal and commercial transport to electric. In India, the transition will be catalysed by the import - assemble - deploy model, but technological indigenisation shall be imperative to match the radically different environmental, economic and demographic needs.
Pye Technologies India is collaboratively working on redesigning the complete electric vehicle stack to suite the Indian needs.

The Battery Pack
Battery packs in electric vehicle typically comprise of individual cells connected in series and parallel to achieve the desired voltage, current, power and energy rating. To indigenise the technology for India, we are focusing the following aspects of cell chemistry, cell geometry, performance regulation and manufacturability.
LITHIUM IRON PHOSPHATE (LFP)
NICKEL MANGANESE COBALT OXIDE (NMC)
LITHIUM COBALT OXIDE (LCO)
CYLINDERICAL/PRISMATIC CELL GEOMETRY
ACTIVE THERMAL MANAGEMENT
MODULAR CONSTRUCTION
Battery Management System
The Battery Management System is the electronics inside a battery pack which provides intelligence and safety features to the pack, the primary role being to balance the individual cells while charging and discharging. We are integrating cloud communication and diagnostic information to out BMS design to enable tracking State of Charge (SoC), State of Health (SoH) of the pack and its usage patterns over its lifecycle.
Upto 120S BATTERY PACK
SMART PASSIVE MANAGEMENT
IN-BUILT SAFETY AND PROTECTION
ACTIVE BATTERY MANAGEMENT
ON BOARD DIAGNOSTICS
CLOUD CONNECTEIVITY
Charger
The electric charger is primarily expected to condition the input electrical energy received from grid, or renewables like solar and wind to the voltage and current levels expected by the battery pack being charged. Our research approach places the charger to be as much a part of the electric grid as it is of an EV system, essentially acting like a smart bridge between the two for two way energy interchange.

Electric Motor
The prime mover inside an electric vehicle, converting electrical energy to mechanical energy, the electric motor has undergone several advancements to meet the demands of the EV industry. Our research mandate aims to achieve those capabilities indigenously while designing it for optimisation of the production and maintenance over its life cycle in thermally challenging environments.
3 Phase AC Induction Motor
AXIAL Flux BRUSHLESS DC Motor
RADIAL Flux BRUSHLESS DC Motor
Switched Multi Rotor ARCHITECTURE
Replaceable, Recyclable NdFeB Substitution
Modular Design for Manufacturability
Motor Driver
The Motor Driver essentially conditions and regulates flow of electrical energy into the motor. We employ advanced power electronics and digital control to achieve high performance of motor drivers. Additional functions like managing reverse flow of electricity in regenerative braking, and active thermal management enhanced safety and reliability are under development.
