Akira batteries are built in state-of-the-art facilities in Yamunanagar, Haryana, using advanced technology and stringent design guidelines. A dedicated team of professionals drives innovation and quality, delivering dependable power solutions to customers.

Role Description

This is a full-time, on-site Power Electronics Engineer role based in Yamunanagar. The Power Electronics Engineer will be responsible for end-to-end technical handling of Li-ion battery chargers: incoming inspection, electrical/functional testing, PCB-level fault diagnosis and repair, assembly from semi-finished parts/PCBAs, calibration, validation and final EOL release.

Overview

• Department- R&D / NPD / Testing & Validation
• Experience- 3-5 years minimum
• Qualification- B. Tech / B.Tech – Electrical / Electronics / Power Electronics / ECE/Electrical& Electronics
• Industry- Li-ion Battery / EV / ESS / Power Electronics/ (CHARGERS, INVERTERS
• Reporting- NPD / R&D
• Product Scope- IP20 & IP67 Li-ion/LFP chargers, CAN and Non-CAN
• Preferred Exposure- SMPS / EV chargers / UPS / industrial power supplies

Key Responsibilities

• Test chargers for AC input range/frequency, no-load and full-load operation, CC/CV accuracy and transition, output ripple, efficiency, power factor, THD, inrush current, thermal performance and burn-in.
• Validate protections including OVP, OCP, short circuit, over-temperature, reverse polarity/backfeed and battery-disconnect behavior.
• Troubleshoot failed chargers to PCB/component level using schematic/block diagrams and electrical measurements.
• Diagnose and replace components such as fuse/MOV/NTC, bridge rectifier, PFC MOSFET/diode/controller, DC-link capacitors, LLC MOSFET/controller, transformer, SR MOSFETs, auxiliary SMPS, optocoupler, sensing circuits, relay, fan and connectors.
• Repair, calibrate and fully revalidate chargers before release.
• Assemble finished chargers from semi-finished PCBA, magnetics, heatsinks, thermal pads, harnesses, fan, connectors, enclosure and communication/control parts.
• For IP67 chargers, ensure correct gasket/O-ring, gland, vent, connector sealing and fastener torque; support IP6X/IPX7 validation.
• Maintain charger test reports, repair history, RCA/8D, burn-in records, EOL records and HW/SW traceability.

Technical Knowledge Requirements

• Power Electronics - AC-DC rectification, EMI/surge protection, active PFC, DC link, flyback, half/full bridge, LLC resonant converter, HF transformer, synchronous rectification, MOSFET gate drive and isolated feedback.
• Charging- LFP/Li-ion CC-CV charging, charge termination, voltage/current sensing, BMS protection coordination, SOC basics and cell/pack OVP/UVP.
• CAN / Non-CAN- CAN-H/CAN-L, termination, bitrate, CAN IDs/messages, BMS-charger handshake and fault/timeout logic; understanding of fixed CC-CV Non-CAN chargers.
• IP & Safety- IP20/IP67 fundamentals, IP2X, IP6X/IPX7, insulation, creepage/clearance, Hi-pot, insulation resistance, earth bond and leakage-current concepts.
• Standards- Working familiarity with IEC 60335-2-29, IEC 60529 and relevant IEC 61000 EMC requirements.

Mandatory Hands- On Skills

• PCB troubleshooting, continuity tracing, soldering/desoldering and SMD/power-component replacement.
• Safe use of multimeter, oscilloscope, differential/current probes, electronic load, battery simulator and power analyzer.
