QUALITY MANAGEMENT

Laboratory Testing & Quality Management

Ensure comprehensive quality control from individual cells to complete battery packs. Based on rigorous safety standards like GB/T47741-2026, our testing matrix pushes the limits of battery reliability under extreme environmental, mechanical, and electrical stress.

Laboratory testing and quality management for batteries
01

Cell Testing (GB/T47741-2026)

Comprehensive evaluation at the cell level ensures baseline safety and performance under abusive conditions. Core tests include:

  • High-Temperature External Short Circuit
  • Overcharge & Forced Discharge
  • Low Pressure
  • Temperature Cycling
  • Vibration & Shock
  • Drop, Impact & Crush
  • Thermal Abuse
  • Nail Penetration
  • Lithium Plating
  • Thermal Runaway
  • Cycle Life

Acceptance Criteria: Tested cells must show no disassembly, no rupture, no fire, no explosion, and maintain targeted capacity retention based on standard requirements.

02

Battery Pack Testing (GB/T47741-2026)

At the system level, testing focuses on environmental durability and electrical protection mechanisms. Key procedures include:

  • Low Pressure & Temperature Cycling
  • Vibration, Shock & Drop
  • Stress Relief
  • Salt Water Immersion
  • Flammability Requirement (V-0)
  • Overvoltage / Overcurrent Charging
  • BMS Mutual Recognition
  • Undervoltage / Overcurrent Protection
  • External Short Circuit
  • Reverse Polarity Protection
  • High / Low Temperature Protection

System Validation: Ensures the Battery Management System (BMS) and physical enclosure consistently safeguard against faults and harsh environments.

Test planning note

The test matrix depends on application risks, relevant standards, sample configuration and the agreed program timeline.
