Application Background

This battery is designed for service robots used in mall guidance, hotel reception, and logistics delivery scenarios.
Robots require long-duration cruising, voice interaction, and stable power support, demanding high endurance, peak discharge capability, and system reliability.

Project Challenges

Continuous operation for 8–12 hours required
High transient load during movement and interaction (up to 60A peak)
Frequent daily charge/discharge cycles requiring cycle stability
Limited internal space with strict size and weight constraints

Customized Battery Solution

High-voltage large-capacity design: 38.4V 21Ah platform for long runtime
Smart communication management: RS485 with SOC monitoring and power display
Multi-level protection system: overcharge, overdischarge, overcurrent, short circuit, temperature protection
Metal plate structure: improved impact resistance and mechanical reliability

Application Results

Continuous runtime extended to 8–12 hours
Improved stability under peak load, reducing system power-off risk by ~30%+
SOC visualization improves operation and maintenance efficiency
Stable cycle performance extends overall service life
