4. Case Study:

A European warehouse automation company required a high-performance 48V lithium battery pack for a heavy-duty Autonomous Mobile Robot operating 24/7 with 800 kg payload capacity. The system needed to deliver stable voltage under 300A peak loads, fit within strict space constraints, support CAN communication, and achieve over 3000 cycles at 80% DOD.
To meet these requirements, a 48V 60Ah LiFePO4 battery pack was engineered with low-resistance busbar architecture, symmetrical current paths, and a custom intelligent BMS featuring high-accuracy SOC estimation, active balancing, and real-time fault diagnostics. The design also incorporated multi-point thermal monitoring and an IP65 aluminum enclosure for industrial durability.

The final solution exceeded performance targets,
After deployment, the customer reported a 22% reduction in unexpected downtime and a 15% improvement in fleet scheduling efficiency. The project demonstrated that optimizing internal resistance, thermal control, and intelligent BMS algorithms is critical for ensuring long-term reliability and operational efficiency in industrial AMR battery systems.

Frequently Asked Questions (FAQ) About AMR Lithium Battery Packs

1. What type of lithium battery is best for AMR applications?

For most industrial Autonomous Mobile Robots, LiFePO4 (LFP) and NMC are the two dominant chemistries.

LiFePO4 offers longer cycle life (3000–5000 cycles), enhanced thermal stability, and higher safety margins. It is widely used in warehouse AMRs.

NMC provides higher energy density and lighter weight, making it suitable for compact or medical robots.

Battery selection depends on runtime requirements, weight constraints, discharge rate, and operating temperature range.

2. What voltage is commonly used in AMR battery systems?

The most common voltage platforms in the US and European markets are:

24V

36V

48V (most widely adopted)

60V

48V systems have become the industry standard for mid-to-heavy-duty warehouse AMRs due to optimized efficiency and motor compatibility.

Cycle life depends on chemistry and depth of discharge (DOD).

Typical values:

LiFePO4: 3000–5000 cycles at 80% DOD

NMC: 1500–2500 cycles at 80% DOD

In 24/7 warehouse operation, this usually translates to 3–5 years of service life under proper BMS management.
