Battery Cell Technology & Smart BMS Architecture
Under brand MEHAR, Lawad Infrastructure Private Limited engineers heavy-duty battery systems specifically for extreme Indian operating environments (-10°C to 55°C). We combine A+ Grade Laser-Welded Prismatic LiFePO4 cells, inter-cell thermal propagation barriers, and microprocessor-governed Smart BMS telemetry to deliver uncompromised safety and cycle life.
From Graded Electrochemistry to Certified Commercial Packs
A structured, automated manufacturing pipeline ensuring zero thermal propagation and uniform pack longevity across 3,000+ deep cycles.
4-Tier Cell Grading & IR Matching
100% of incoming cells undergo automated capacity sorting and AC/DC internal resistance (IR) matching within ±1.5% delta to eliminate premature cell drift.
Fiber Laser-Welded Busbars
High-precision automated laser welding fuses solid copper and aluminum busbars directly onto terminal studs, eliminating high contact resistance and screw loosening.
Thermal Propagation Barrier
Inter-cell aerogel and ceramic-silicone insulation pads isolate every cell, preventing thermal runaway cascading per AIS-156 Amendment III Phase 2 standards.
Smart BMS & EOL Validation
Integrated microprocessor BMS calibration, CAN/RS485 firmware flash, and 100% automated End-of-Line (EOL) full-cycle charge/discharge validation.
Primary Technology (EV & ESS)Large-Format Prismatic LiFePO4 Cells
Prismatic cells are the engineering benchmark for Indian commercial EVs (E-Rickshaws, 2W fleets, Forklifts) and stationary ESS. Housed in laser-welded aluminum shells with integrated explosion-proof safety vents, they provide high volumetric efficiency, superior heat dissipation through flat aluminum faces, and up to 90% fewer electrical interconnects than cylindrical arrays.
Raw Cell Supply (18650 / 21700 / 32700)Cylindrical Li-Ion Cells (18650, 21700, 32700)
Direct factory supply of Grade-A cylindrical cells for specialized B2B battery pack assemblers, light e-cycles, power tools, and portable industrial instruments. High discharge rate capability (3C–5C continuous) with individual steel can explosion-proof CID pressure valves.
Microprocessor Smart BMS Architecture & IoT Telemetry
How MEHAR protects, monitors, and optimizes battery performance in real-time through hardware-level fail-safes and cloud connectivity.
Smart BMS Exploded Engineering ViewMulti-Tier Hardware Protection & Telematics
Every MEHAR battery pack features a dedicated microprocessor-based Smart BMS equipped with multi-stage solid-state switching, real-time SoC/SoH algorithms, and cloud fleet telemetry.
4-Point NTC Thermal Guard
Multiple thermal thermistors monitoring cell clusters and power MOSFETs with automatic charge/discharge cutoff at >55°C and sub-zero protection.
Active Cell Balancing
Microprocessor-driven active charge redistribution equalizes cell voltages during operation, preventing premature pack shutdown and extending service life.
Dual Solid-State Power MOSFETs
Sub-millisecond short-circuit and overcurrent disconnect with zero contact arcing, backed by redundant hardware hardware comparator circuits.
CAN 2.0B / Bluetooth & 4G IoT
Full telemetry integration with vehicle speedometers, motor controllers, and 4G cloud fleet dashboards for GPS tracking, geo-fencing, and remote diagnosis.
Full Alignment with Indian Automotive & Industrial Standards
Lawad Infrastructure Private Limited designs, tests, and manufactures MEHAR battery packs in strict accordance with AIS-156 Amendment III Phase 2, AIS-038 Rev 2, BIS IS 16046 (Part 2:2018), and UN 38.3 transport safety requirements.
