Executive overview: optimizing material handling performance with XICHA lithium-ion battery solutions

A focused two-week measurement captured real amp-hour demand at a U.S. facility running two 10-hour shifts. Peak-day draw hit 1,426 AH and average-day use was 1,380 AH. That produced an EBU of 1.9 on peak days and 1.84 on average.

The result: the site’s 935 AH lead-acid packs (usable ~748 AH at 80%) could not sustain a full shift without swaps, lengthy cooling windows, or excess charger capacity.

About the customer and facility footprint

The customer operates a multi-shift warehouse with sit-down counterbalance forklift equipment that cycles intensively across inbound, storage, and outbound handling.

XICHA’s role as the energy solution provider

XICHA begins with detailed energy analysis and follows through with battery selection, charger strategy, and safe integration with existing equipment and workflows.

• We right-size packs using measured amp-hour and EBU data.
• We assess charger placement, power availability, and travel paths for opportunity charging.
• We translate findings into operational steps that cut downtime and stabilize throughput for customers.

Present-day logistics challenges with lead-acid power sources

Many multi-shift warehouses still wrestle with limitations tied to traditional lead-acid power sources. These limits show up as lost hours, heavier labor, and space tied to charging infrastructure.

Runtime limits, cooling periods, and swap labor

Runtime ceilings force unplanned stops for charging or battery swaps. Long charge and mandated cooling windows require extra crews and slow down operations.

• Frequent swaps add labor and interrupt workflows for busy forklifts fleets.
• Cooling time creates gaps that reduce asset availability during peak demand.
• Backup inventory and charging docks consume valuable floor space and time.

Maintenance, storage, and disposal costs versus ESG expectations

Lead-acid units demand watering, terminal care, and strict storage controls. These routines raise direct maintenance costs and create regulatory burdens for disposal and recycling.

• Charging inefficiency (typically 70–80%) increases utility bills versus newer chemistries.
• Dedicated battery rooms require ventilation, safety gear, and capital outlay.
• XICHA offers solutions that cut these costs by enabling shorter charge windows and opportunity charging.

Baseline operation and power study approach

To establish a reliable baseline, we logged real amp-hour demand across two 10-hour shifts at the customer site.

Two-shift sit-down counterbalance use case and daily amp-hour demand

We monitored sit-down counterbalance trucks over two weeks using data logging rather than estimates.

Measured daily amp-hour draw reached 1,426 AH on the peak day and averaged 1,380 AH. Packs were 935AH rated with ~748AH usable at 80%.

EBU methodology to quantify energy needs and battery suitability

EBU equals daily amp-hours divided by usable capacity. For this customer, that produced 1.9 on the peak day and 1.84 on average.

Guidance: 0–1 conventional lead‑acid; 1–1.25 opportunity charging lead‑acid; 1.25–1.60 fast‑charge lead‑acid; 1.60–3+ suggests lithium is preferable.

Findings: peak-day versus average-day usage and implications for fleet sizing

EBU above 1.6 shows a single lead-acid pack won't meet daily demand without swaps or extra packs.

Options included two lead-acid packs per truck with swap labor or a single modern pack with opportunity charging and fewer interruptions.

"Right-sizing must meet both average and worst-case demand to avoid mid-shift slowdowns."

• Results guide charger count, placement, and power planning for trucks and routes.
• The methodology scales across zones and supports fleet sizing as operations grow.

Case Study: Use of Lithium-Ion Battery Forklifts in Logistics Enterprises

Measured energy and duty cycles forced a clear operational choice for the customer's multi-shift warehouse.

Decision criteria: swaps versus a single pack

Key factors included EBU near 1.9, 10-hour shifts, route intensity, and charger access. Those metrics showed two lead-acid batteries per truck would add swaps, cooling time, and extra labor.

The practical choice favored a single, fast-charge pack sized for peak-day amp-hour demand. This reduces storage space and simplifies workflows.

Right-sizing across a mixed fleet

Right-sizing considers peak energy, acceptable depth-of-discharge, and available top-off windows. Mixed fleets need tailored packs by lift truck class, attachments, and utilization patterns.

• Pair pack capacity with charger amperage to keep state of charge above runtime thresholds.
• Map duty cycles so each truck meets daily needs without excess inventory.
• XICHA’s engineers match pack voltage and chargers to the fleet and facility constraints.

"Right-sizing must meet both average and worst-case demand to avoid mid-shift slowdowns."

Solution design: fast charging, opportunity charging, and BMS-enabled safety

When chargers and packs align with duty cycles, operators spend less time off the floor and more time moving material.

Reducing downtime with one- to two-hour charges and break-time top-offs

XICHA’s solutions center on one- to two-hour fast charges and structured top-offs during scheduled breaks. This approach keeps state of charge in target bands and removes many mid-shift interruptions.

Temperature adaptability for ambient and cold storage operations

Modern lithium-ion batteries hold capacity across wide ranges, from −40°C to 60°C. That makes them a reliable source of power for both ambient and cold storage zones without the deep capacity loss seen with older chemistries.

Built-in protections and real-time monitoring for safer forklift operations

A multi-layer BMS provides telemetry on voltage, current, temperature, and capacity. Real-time alerts and predictive maintenance lower risk and stabilize operations.

• Opportunity charging cuts backup inventory and frees floor space.
• Charging efficiency (>90%) saves utility costs and time.
• XICHA specifies chargers, cables, and interlocks to match site constraints, translating this study into a practical solution for material handling.

Measured impacts on productivity, costs, and space utilization

Measured fleet telemetry showed clear gains in daily runtime and trimmed spare inventory needs. XICHA’s platform converts brief breaks into effective top-offs, turning downtime into moving time.

More operating hours per day and fewer backup batteries

Facilities typically gain 1–2 additional operating hours per day per truck by replacing swap cycles with opportunity charging. That extra lift time reduces the need for duplicate packs and dedicated charging rooms.

Fewer spares means less capital tied up and simpler workflows. Teams spend more time handling material and less time staging and swapping cells.

Lower total cost of ownership through efficiency and extended lifespan

Charging efficiency above 90% and expected lifespans of 5–8 years cut annualized costs versus older chemistries that operate at 70–80% efficiency and shorter service lives.

• Converted swap time becomes usable runtime, improving overall productivity and fleet availability.
• Consolidating to a single pack removes backup inventory and frees floor space for revenue use.
• Reduced maintenance—no watering or equalization—lowers labor and error risks for dealers and operators.

"Real-time data lets customers fine-tune charger placement and break timing to maximize fleet utilization."

XICHA backs dealers and customers with periodic reviews and data-driven adjustments. These steps confirm ongoing performance and keep total costs down while boosting material handling productivity.

Strategic considerations for dealers and logistics customers

Dealers and fleet managers need clear thresholds to decide when an energy platform change will deliver measurable uptime gains.

Start with an operational audit that captures daily amp-hour draw and EBU. When EBU consistently reaches or exceeds 1.6, the data favors a transition away from older power sources.

For dealer partners and customers, this means aligning offers to measured needs rather than one-size-fits-all packages.

When to transition from internal combustion or lead-acid

Operations with long shifts, frequent peaks, or constrained service windows see the fastest payback from higher-efficiency packs and opportunity charging. Emissions reduction and lower service complexity also make this a strong choice for facilities focused on sustainability and lower TCO.

• Evaluate EBU first: ≥1.6 signals the right solution for uptime and cost.
• Multi-shift sites benefit from removing swap cycles and reclaiming floor space.
• Cold-storage or high-heat sites should choose components with BMS thresholds matched to the environment.
• Dealers can position offerings around lifecycle value, predictable maintenance, and space recapture.

"A structured study validates charger counts, circuit capacity, and placement to support route-based top-offs."

Conclusion

Quantified runtime needs provided a clear guide for selecting the right energy platform for the fleet.

The recorded average‑day 1,380 AH and peak 1,426 AH with an EBU near 1.84–1.9 showed a single lead‑acid pack could not meet demand without swaps. XICHA’s solution paired right‑sized packs with opportunity and fast top‑offs to remove swap downtime and free charging space.

Results: one‑ to two‑hour charging, >90% charge efficiency, wide temperature operability (−40°C to 60°C), and multi‑year service translate into higher throughput and lower lifecycle costs.

BMS data and periodic reviews keep risk low and let dealers tune charger placement as operations grow. XICHA turns this paper’s insights into field‑proven solutions that sustain performance at the facility level.
