Job description

Position Summary

The Application Engineer will serve as the technical bridge between ENEPL's battery pack design and OEM vehicle platforms, primarily E-Rickshaw (L3) and E-Auto (L5) applications. The role requires deep understanding of powertrain-battery interaction, cell electrochemistry, and system-level integration to ensure batteries are correctly matched, validated, and optimized for each vehicle platform.

Key Responsibilities

Battery-Vehicle Integration

• Own the technical integration of LFP battery packs with L3 and L5 vehicle platforms — mechanical fitment, electrical interfacing, thermal management, and mounting/enclosure compatibility.
• Work with OEM engineering teams to define battery pack specifications (voltage, capacity, form factor, connector, BMS communication protocol) matched to vehicle requirements.
• Support design reviews for new platform onboarding, including CAD fitment checks, wiring harness routing, and connector/interface finalization.

Powertrain Characterization

• Analyze motor controller, motor, and drivetrain load profiles (torque-speed curves, peak/continuous current draw, regen braking characteristics) to define battery discharge/charge requirements.
• Correlate vehicle duty cycles (start-stop, gradient, payload, range requirements) with battery sizing, C-rate capability, and thermal derating limits.
• Validate battery performance against powertrain demands through road trials, bench simulation, and data logging (voltage sag, current spikes, temperature rise).

Cell Chemistry & Pack Performance

• Apply working knowledge of LFP (LiFePO4) cell chemistry — voltage curves, SOC-OCV relationship, internal resistance (ACIR/DCIR), cycle life behavior, and temperature sensitivity — to application-level decisions.
• Support cell/vendor evaluation and IQC teams by translating chemistry-level cell data into application performance implications (range, life, safety margins).
• Provide input on charge/discharge protocols, derating curves, and BMS parameter settings based on cell characteristics and application duty cycle.

Field Support & Issue Resolution

• Investigate field performance issues (range shortfall, premature capacity fade, thermal events) with a systems view spanning cell, BMS, and vehicle integration.
• Conduct root cause analysis for application-specific failures and recommend corrective actions in coordination with R&D, Quality, and Service teams.

Documentation & Validation

• Prepare application-specific test plans, DVP inputs, and validation reports for new vehicle platform qualification.
• Maintain technical documentation: integration guides, interface control documents, and application notes for each OEM/platform.

Required Qualifications

• Education: Diploma / B.Tech in Electrical or Electronics Engineering.
• Experience: 2–5 years in EV battery application engineering, preferably with exposure to L3/L5 category vehicles (E-Rickshaw, E-Auto, E-Loader).

Technical Knowledge

• Strong understanding of LFP cell chemistry — voltage behavior, SOC estimation, cycle life, thermal characteristics, and safety limits.
• Working knowledge of EV powertrain fundamentals — BLDC/PMSM motor behavior, motor controller current/voltage demands, regenerative braking, and load profile analysis.
• Familiarity with BMS functions (protection thresholds, balancing, communication protocols — CAN/UART/BLE) and how they interface with vehicle systems.
• Understanding of AIS 156 and related regulatory/safety standards for EV batteries in India.
• Ability to read and interpret electrical schematics, wiring harness diagrams, and mechanical fitment drawings.

Skills

• Data analysis proficiency (Excel; Python a plus) for interpreting field/test data.
• Strong cross-functional coordination — works closely with R&D, Quality, Manufacturing, and OEM customer teams.
• Structured problem-solving with physics/data-based justification (not assumption-based conclusions).

Desired Attributes

• Prior hands-on experience with E-Rickshaw/E-Auto OEMs or Tier-1 battery/BMS suppliers.
• Exposure to thermal management design considerations for battery packs in tropical/Indian operating conditions.
• Willingness to travel for OEM site visits, field trials, and customer technical discussions.
