Traditional AGV TCO Traps
Lead-Acid Battery Hidden Costs
When you rely on lead-acid batteries for your AGVs, you encounter hidden costs that can significantly inflate your total cost of ownership (TCO). Regular maintenance is essential for these batteries. You must consistently water them, clean terminals, and perform periodic equalization. These ongoing maintenance needs lead to increased service interventions, which can accumulate significant costs over time.
For example, a lifecycle cost comparison for a typical high-throughput AGV might look like this (costs aggregated over 5 years):
Battery Type | Lifecycle Cost Components (5-Year Estimate) |
Lead-acid batteries | (Initial purchase × Average 3 replacements)+labor/material for watering & equalization + Floor space/HVAC cost +significant downtime losses |
LiFePO4 solution | Initial purchase (1 unit) + minimal labor/material for inspection + Infrastructure upgrade costs |
Operational downtime resulting from battery failures creates significant disruptions to workflows. This downtime can lead to costly labor idle time and delays in critical shipments. The combined impact can amount to $100–$300 per hour, depending on your operation’s scale.
Downtime and Productivity Loss
Downtime is a major concern when using lead-acid batteries in AGVs. Charging pit stops can result in a loss of 5-10 minutes of productive time per cycle. In fact, AGVs can consume 15-20% of their operational time waiting for power. To compensate for this downtime, companies often maintain AGV fleets that are 20-35% larger than necessary.
The inefficiencies associated with charging account for 20-30% of total robot operational time. This can slow down order fulfillment, reducing overall operational efficiency by up to 15%. By addressing these downtime issues, you can significantly enhance productivity and reduce costs.
With high-power lithium batteries, you can achieve substantial downtime reduction, allowing your AGVs to operate more efficiently and effectively.
