简体中文The battery system inside an Automated Guided Vehicle (AGV) plays a far bigger role than simply supplying power. It directly affects operating hours, maintenance requirements, charging strategy, overall efficiency, and the long-term cost of ownership.
With AGVs now running in 24/7 environments—from cleanrooms to heavy-industry plants—choosing the right battery technology has become a key part of AGV planning.
This article explains the differences between the three most widely used AGV power systems: lead-acid batteries, lithium-ion batteries, and fast-charging technologies. More importantly, it explores how each option fits into different types of workflows.
Why Battery Choice Matters for AGV Performance
Battery selection affects much more than run time. It shapes:
How often an AGV needs to charge
The size of the charging infrastructure
Routing and scheduling strategies
Maintenance routines
Energy efficiency
Total lifetime cost
In other words, the right battery keeps an AGV fleet running smoothly and helps avoid bottlenecks or unnecessary downtime.
Lead-Acid Batteries: The Classic Workhorse
Lead-acid batteries have powered industrial equipment for decades, and many early-generation AGVs were designed around them.
1 What Makes Lead-Acid Batteries Appealing
While less common today in high-performance AGV fleets, lead-acid still has a few clear benefits:
Lower upfront investment
Proven, mature technology
Simple charging equipment
Reliable performance for light workloads
For facilities with limited budgets or low-intensity transport needs, lead-acid can still be a viable option.
2 Practical Limitations to Consider
However, lead-acid batteries come with several drawbacks that impact modern automation:
Long charging times (typically 6–8 hours)
Reduced lifespan if discharged too deeply
Frequent maintenance—water refilling, equalization
Heavy weight, affecting AGV design
Lower energy density
In fast-paced production lines or 24/7 warehouses, these disadvantages often create operational constraints.
3 Best Use Cases
Lead-acid batteries still work well in:
Low-duty cycles
Small plants with minimal AGV usage
Non-critical, short-distance tasks
Environments where downtime is not a major issue
But overall, most modern AGV projects now prefer lithium-ion solutions.
Lithium-Ion Batteries: The Modern Standard for AGVs
Lithium-ion batteries have become the dominant choice for AGVs in recent years—and for good reason.
They offer a strong combination of performance, efficiency, and safety.
1 Key Advantages
Lithium-ion technology provides several benefits that align well with the needs of smart factories:
Fast charging (typically 1–2 hours)
Long cycle life—often 3x–4x longer than lead-acid
High energy density—more power with less weight
Minimal maintenance
Stable performance during heavy workloads
For AGVs operating around the clock, these advantages create a much smoother and more predictable workflow.
2 Safety and Thermal Performance
Modern AGV lithium-ion batteries include:
BMS (Battery Management System)
Temperature monitoring
Overcharge and discharge protection
Cell balancing
Fault alarms
These features help ensure reliability even in demanding conditions such as cleanrooms, refrigerated warehouses, or high-humidity environments.
3 Where Lithium-Ion Excels
Lithium-ion is ideal for:
Multi-shift production environments
Long travel distances
Heavy-duty AGVs
High-accuracy, high-responsiveness tasks
Facilities aiming for fully automated operation
In short—if your workflow requires consistency, lithium-ion is usually the best choice.
Fast-Charging Systems: For High-Frequency, High-Speed AGVs
As AGVs become more integrated into continuous production, many factories are turning to fast-charging or opportunity-charging systems.
These are often powered by:
Supercapacitors
LTO (Lithium Titanium Oxide) batteries
Hybrid energy systems
Unlike conventional batteries, these solutions offer rapid bursts of energy.
1 The Main Appeal: Minimal Downtime
Fast-charging systems allow AGVs to recharge in:
30 seconds
1 minute
3 minutes
During routine stops
This makes them perfect for workflows where the AGV has short waiting periods between tasks.
2 Strengths of Fast-Charging Systems
Extremely long cycle life (tens of thousands of cycles)
Ultra-fast charging
High power output
Ideal for repetitive, tight-cycle tasks
Supports nearly continuous operation
3 Trade-Offs to Know
Lower total energy capacity than lithium batteries
Typically require dedicated charging pads
Best suited for predictable, short-distance paths
If your AGVs move constantly throughout the day with short pauses, fast-charging technology can create significant efficiency improvements.
How to Choose the Right Battery for Your AGV Fleet
Selecting the correct battery type depends on the structure of your workflow—not just cost.
Here’s a simple decision framework:
1 Choose Lead-Acid If:
Budget is extremely limited
The AGV is used a few hours per day
Overnight charging is acceptable
Maintenance is not a concern
2 Choose Lithium-Ion If:
Your factory runs multiple shifts
AGVs must operate for extended hours
You need stable, reliable performance
You want minimal maintenance
Charging downtime must be reduced
3 Choose Fast-Charging Systems If:
AGVs operate almost nonstop
The route includes frequent short stops
High cycle speed is required
You need near-continuous performance
High precision or fast transfers are part of the workflow
