Cold Storage Battery Requirements: Performance and Custom Solutions

Cold storage warehouses place additional demands on material handling batteries. Low temperatures can affect available capacity and power, while condensation and limited charging windows create additional operational challenges.

For forklifts, pallet trucks, automated guided vehicles (AGVs) and other material handling equipment, choosing a suitable cold storage battery means matching its specifications to the warehouse environment, equipment requirements and daily operating schedule.

This guide explains what to consider when specifying a cold storage lithium battery, planning charging for multi-shift operations and evaluating a custom solution with ACE Battery.

What Battery Specifications Are Needed for Cold Storage?

The right cold storage battery depends on the minimum operating temperature, equipment workload and conditions under which the battery will be charged.

Operating temperature and performance

Low temperatures slow the electrochemical reactions inside lithium batteries. Depending on the battery design and operating conditions, this can reduce available capacity and power, affecting equipment performance and operating time between charges.

A refrigerated warehouse and a deep-freeze facility may require different battery configurations. Specify the typical and minimum ambient temperatures, then ask the supplier to confirm the expected battery performance under those conditions.

If the application requires operation at temperatures as low as -40°C, identify this requirement at the beginning of the project. The applicable configuration, test conditions and performance limits should be confirmed rather than inferred from a temperature rating alone.

Charging temperature and temperature management

Operating temperature and charging temperature are separate specifications. Charging lithium batteries below their permitted temperature range can cause lithium plating and cell damage, so the battery management system (BMS) may restrict or prevent charging in unsuitable conditions.

Confirm where charging will take place, the permitted charging temperature range and whether temperature management is required. A battery designed for low-temperature operation should not automatically be assumed to support charging at the same temperature.

Moisture protection and equipment compatibility

Condensation can form when equipment moves between cold and warmer areas. Ask the supplier what moisture-protection measures are available and request relevant technical specifications for the proposed configuration.

The battery must also fit the equipment's electrical and mechanical requirements. Before selecting a forklift battery or AGV battery, confirm:

• Electrical requirements: Voltage, capacity, current demand, connectors and communication interfaces.

• Installation requirements: Battery dimensions, mounting and available compartment space.

• Operating profile: Daily working hours, workload and expected energy consumption.

• Environmental conditions: Minimum temperature, charging location and potential moisture exposure.

These details help determine whether an existing configuration is suitable or a customized battery needs to be evaluated.

What Charging Configuration Is Needed for Multi-Shift Operations?

For warehouses operating two or three shifts a day, battery capacity is only part of the decision. The charging configuration must support daily energy demand without creating unacceptable equipment downtime.

Start by assessing the number of shifts, operating hours, break periods, energy consumption and time available for charging. These factors help establish whether the application needs greater battery capacity, planned charging opportunities, fast charging or a combination of approaches.

Evaluating fast charging

ACE Battery's Lightning Charge System supports charging rates of up to 2C as an optional configuration. This may help reduce charging downtime when the selected battery and charging system are designed to support the required rate.

A 2C rating does not by itself establish the actual charging time or guarantee uninterrupted three-shift operation. Suitability depends on battery capacity, charger compatibility, permitted charging current, temperature conditions and available charging windows.

For cold storage applications, confirm whether the required charging rate is supported at the intended temperature and whether temperature management or other charging restrictions apply.

ACE Battery's Multiple Shifts Li-ion Battery Solution is designed to address the needs of three-shift-a-day operations. The proposed configuration should be assessed against the equipment's duty cycle and charging schedule.

How ACE Battery Can Customize a Cold Storage Lithium Battery

ACE Battery develops lithium battery solutions for material handling applications. Depending on the equipment and operating requirements, customers can discuss customization of voltage, capacity, dimensions, interfaces and temperature-control configurations.

Available options for cold storage and multi-shift applications can include:

• Low-temperature operation: Configurations can be evaluated for operating requirements down to -40°C, subject to technical feasibility and the applicable specifications.

• Moisture protection: Special waterproof treatment for electrical components can be considered according to the application's requirements.

• Temperature control: A temperature-controlled environment inside the battery box can be evaluated for projects that require it.

• Fast charging: Charging rates of up to 2C can be considered as an optional configuration, subject to battery, charger and operating-condition compatibility.

These are application-dependent options, not features that should be assumed to come standard with every battery. The feasibility of combining low-temperature operation and fast charging must be assessed for the specific configuration.

ACE Battery's 24V 50Ah Material Handling Battery is a relevant product reference for businesses evaluating batteries for material handling equipment. It provides a starting point for discussing application requirements; it should not be assumed to include every optional low-temperature or fast-charging feature.

If your equipment requires different electrical specifications, dimensions, interfaces or environmental capabilities, ACE Battery can assess the requirements and discuss a suitable custom configuration.

Discuss Your Custom Battery Requirements with ACE Battery

ACE Battery can help evaluate custom lithium battery configurations for material handling equipment used in cold storage and multi-shift operations.

Share your equipment model, required voltage and capacity, minimum operating temperature, daily workload, charging arrangements and installation dimensions. If you require operation at -40°C, fast charging up to 2C or a specific temperature-control configuration, include these requirements so their technical feasibility can be assessed.
