Application Background

This battery solution is specifically designed for chess robots, suitable for human–machine gameplay, teaching demonstrations, and intelligent interaction applications.

The system requires stable power delivery to drive motors and control units during long operating periods, with frequent motion response, placing high demands on runtime, surge discharge capability, and overall system stability.

Project Challenges

  • Continuous operation required for 4–6 hours or more
  • Instant motor drive current up to 12A requiring strong discharge capability
  • 18V system platform with strict output stability requirements
  • Compact installation space (22 × 90 × 153 mm) requiring optimized structure design

Customized Battery Solution

  • 5S2P 18V configuration with 91.8Wh rated energy for sustained operation
  • Supports 12A surge discharge to ensure fast motor response
  • Integrated intelligent protection system (overcharge, overdischarge, overcurrent, short circuit) for enhanced safety
  • Low internal resistance design (≤300mΩ) improves instantaneous power delivery performance

Application Results

  • Supports continuous gameplay operation for 4–6+ hours
  • Improved motor response consistency during repetitive actions
  • Enhanced overall system reliability and operational safety
  • Compact structure enables efficient integration inside robot housing
