4. **Battery Management System (BMS) Development**
   - Programming BMS for **state-of-charge (SOC)** and **state-of-health (SOH)** monitoring.
   - Designing fault detection and cut-off protocols for short circuits, overcharging, or thermal runaway.
   - Integrating with telematics for fleet-level monitoring.
5. **End-of-Life & Recycling**
   - Designing packs for **disassembly and recyclability**.
   - Exploring **second-life use cases** (stationary storage, solar integration).

## **Required Skills**

- **Electrochemistry Fundamentals**: Knowledge of lithium-ion (LFP, NMC) and emerging solid-state chemistries.
- **Thermal Engineering**: Understanding heat transfer, fluid dynamics, and thermal materials.
- **Battery Simulation Tools**: MATLAB Simulink, AVL Cruise, ANSYS Fluent for battery performance and thermal modeling.
- **Data Analytics**: Battery health monitoring using IoT sensors, predictive degradation analysis.
- **Embedded Systems Knowledge**: For programming BMS and integrating it with the vehicle's CAN bus.
- **Standards & Compliance**: AIS-156, ISO 26262 (functional safety), IEC 62660 (performance testing).

## **Industry Examples**

- **Ola Electric**: Developing in-house "Bharat Cell" lithium-ion technology to reduce import dependency.
- **Exide Energy Solutions**: Setting up a 12 GWh cell manufacturing plant in Bengaluru, requiring hundreds of battery engineers.
