L S Chandana

Battery systems engineer with end-to-end experience across pack design, standards compliance, and techno-commercial evaluation, now focused on applying that depth to structured procurement analysis and technical writing. At Turno, sized and solutioned 12+ BESS pack designs (10 kWh–800 kWh) and led a formal multi-vendor LFP cell procurement evaluation — building weighted supplier scorecards and total-cost-of-ownership models to compare candidate cell suppliers on price, cycle-life claims, and technical fit. Comfortable translating dense cell-, pack-, and standards-level detail (UL 1973/1974, UN 38.3, IEC 62619) into clear technical proposals, compliance matrices, and decision documents for both engineering and commercial stakeholders.

Background spans automotive-adjacent stationary storage rather than automotive OEM work, with direct exposure to cell sourcing trade-offs, supplier qualification evidence, and cost-performance modelling that transfers directly to procurement consulting and curriculum development.

Stationary energy storage (second-life LFP BESS)

• Led a three-vendor LFP cell procurement evaluation (candidate suppliers assessed on technical and commercial criteria) — built a four-sheet decision workbook with weighted scoring, TCO modelling and an open-items tracker, isolating landed cell price and third-party cycle-life verification as the key unresolved inputs before award.
• Built business-case inputs — ROI, payback-period and LCOE considerations — to support techno-commercial evaluation and configuration trade-offs during pre-sales and supplier selection.
• Authored Statements of Requirements (SoR) and Design Verification Plans (DVP) used as compliance evidence and tender documentation, and prepared compliance checklists/matrices for supplier and system qualification.
• Sized and solutioned BESS across the 10 kWh–800 kWh range — battery capacity and PCS/inverter sizing plus auxiliary-component selection driven by customer load profiles, C-rate duty, round-trip efficiency, degradation, availability and grid requirements.
• Executed UL 1973, UL 1974 and UN 38.3 testing at cell and pack level and led FAT/SAT for deployed systems; running IEC 62619 qualification (BIS-aligned) and scoping NFPA 855 / UL 9540A thermal-runaway propagation testing.
• Delivered 12+ pack designs from 10 kWh residential to an 800 kWh grid-tied industrial BESS across LFP (prismatic, pouch, cylindrical) and NMC chemistries, spanning HV architecture, PCS/inverter and BMS integration.
• Served as technical lead in customer engagements — translating requirements into technical assessment reports and proposals, delivering solution presentations and freezing system specifications for both engineering and commercial audiences.
• Prepared tender and compliance documentation — technical proposals, single-line diagrams (SLD), BOM and datasheet inputs — and addressed customer technical queries with system-optimization recommendations.
• Led a 4-engineer team and drove cross-functional design reviews with R&D and mechanical teams, plus produced comparative technical benchmarking against competitor pack datasheets.

(2019-01 - 2024-01)

• Maintained electrical distribution, fire-detection and life-safety systems across multi-site retail and manufacturing facilities; planned preventive-maintenance schedules and led emergency-response drills.
• Self-directed transition into battery engineering: completed an 11-month Battery + BMS program (Techlanz) covering cell fundamentals, modelling, BMS hardware/firmware and packaging — culminating in the pivot to Turno.
