Full Custom Battery Pack Spot-Welding & BMS Integration Services
GEB provides comprehensive OEM pack assembly across all cylindrical cell formats. We operate high-precision automated grading lines (sorting cells within ±2mV voltage and ±1mΩ ACIR tolerance), pneumatic inverter spot welders with 99.9% pure nickel busbars, flame-retardant cell holders, high-performance Seiko/TI protection circuit modules (PCM/BMS), and custom heat-shrink PVC or aluminum enclosures tailored to your CAD specifications.
Safety Mechanics: CID Pressure Relief, PTC Thermistors & Cell Pairing
Cylindrical metallic can designs offer superior physical crush resistance compared to flexible pouches. GEB integrates triple-tier mechanical safety inside each single cylindrical cell:- Current Interrupt Device (CID): An internal micro-diaphragm that automatically disconnects electrical contact when internal cell pressure exceeds 1.0–1.2 MPa due to abnormal abuse.
- Positive Temperature Coefficient (PTC) Thermistor: Restricts electrical conductivity if thermal temperatures exceed 120°C, self-limiting external short-circuit current.
- Automated Cell Sorting (Voltage, IR, Capacity): Automated grading line sorting cells into narrow bins (±2mV, ±1mΩ, ±10mAh), eliminating serial pack degradation.
- Flame-Retardant Inter-Cell Spacers: High-impact ABS/PC modular cell holders maintaining 1.5mm thermal isolation gaps between adjacent cells to prevent thermal cascading.
OEM / ODM Custom Cylindrical Battery Pack Assembly
GEB offers complete pack engineering services from single-cell prototypes to high-volume multi-kilowatt production runs:- Custom Series & Parallel Arrays: 1S through 32S configurations (3.7V to 115V DC) with capacities scaled from 650mAh to 500Ah+.
- Spot-Welded Nickel Strips & Busbars: 0.15mm to 0.3mm pure nickel or nickel-copper composite busbars welded via precision inverter DC spot welders.
- Protective Circuit Integration: Built-in PCM/BMS providing overcharge, over-discharge, over-current, short-circuit, and NTC thermistor temperature sensing.
- Enclosure Varieties: Blue PVC heat shrink, epoxy fiberglass sheet encasements, aluminum alloy extruded casings, and IP67 waterproof molded shells.
