With the rapid iteration of intelligent manufacturing and automated warehousing and logistics, the application of AGVs (Automated Guided Vehicles) has long since broken through the traditional model of "standard vehicle model + universal battery". Standard lithium batteries are no longer sufficient to meet the needs of AGV projects with different scenarios and loads, and non-standard customization is becoming a necessity for more and more companies—irregular sizes, special voltages, extreme environments, high-power fast charging, intelligent automatic charging... these scenarios all place strict requirements on lithium battery solutions. So, faced with various "customized battery solutions" offered by lithium battery suppliers, how do we determine whether they truly fit our business?
The primary prerequisite for a customized solution is compatibility with the battery compartment, seamless connectivity, and easy installation; otherwise, even the strongest performance is meaningless.
Structural dimension adaptation. AGV models vary widely, with significant differences in chassis space and installation interfaces between submersible, forklift-type, and heavy-duty AGVs. Customized solutions must precisely match equipment dimensions and even support irregular structural designs to maximize equipment space utilization. Fixing methods—bolt fastening, sliding rail pull-out, or hanging—directly determine on-site modification costs and subsequent maintenance convenience.
Whether the voltage platform (e.g., 24V/48V/72V/96V/144V), charging interface type (manual plug-in/unplug, automatic docking, wireless charging coil position), and communication protocol (CAN, RS485, Modbus, EtherCAT, etc.) are seamlessly integrated with the existing AGV control system to avoid secondary development or additional adapter boards.
Especially for lifting AGVs and lurking lifting AGVs, the weight of the battery and its placement within the vehicle body will affect the overall stability and lifting accuracy. The center of gravity and axle load distribution need to be checked simultaneously during customization.
The performance parameters of AGV lithium batteries directly determine the equipment's operating efficiency and stability. When determining a customized solution, it is necessary to combine the actual needs of the project and focus on the four core parameters of "voltage, capacity, rate, and cycle life" to achieve "precise matching". This will avoid over-customization that would lead to cost waste and prevent insufficient performance from affecting the project's progress.
Commonly used lithium battery voltage platforms for AGVs are 24V, 48V, and 72V. These voltages must be fully matched to the voltages of the AGV motor and controller; otherwise, power loss and equipment failure will occur. Capacity design must be calculated using the following formula: Capacity (Ah) = Average Power (W) × Running Time (h) / Battery Voltage (V).
Frequent starts and stops, as well as climbing hills, generate instantaneous high currents in AGVs. Customized solutions require the use of battery cells that support continuous discharge at ≥1C. For heavy-duty AGVs, the discharge rate can be increased to 2C-3C to ensure stable voltage without voltage drops. Charging and discharging efficiency directly affects operational continuity. Current high-quality customized solutions can support 1.5-2 hours of fast charging, meeting the charging window requirements for AGV shift operations. At the same time, by optimizing the battery cell formula, the cycle life is avoided due to fast charging.
The industry average requirement for AGV lithium batteries is ≥1500 cycles. High-quality customized solutions, through standardized operations of capacity matching and grouping, can extend the cycle life to over 2000 cycles, or even 3000 cycles, significantly reducing battery replacement frequency and maintenance costs. When evaluating a solution, it's crucial to ensure the manufacturer provides actual cycle test data, rather than just theoretical values, to avoid rapid capacity degradation later on.
The application scenarios for AGVs vary greatly, ranging from general warehousing and automobile manufacturing workshops to cold chain storage and hazardous chemical environments. These different scenarios place drastically different demands on the environmental tolerance, protection level, and structural dimensions of lithium batteries, which is the core starting point for customized solutions. Determining scenario suitability requires focusing on three key details, rather than simply looking at the parameter table.
For outdoor or dusty and humid environments, the protection level of the battery pack should be given special attention, and it should be at least IP54 or higher. For dusty building materials and woodworking workshops, IP65 is recommended. Food, cold chain and cleaning areas may require IP66/IP67. For outdoor ports, docks and other high salt spray environments, the corrosion resistance level should also be considered.
Environmental tolerance is important. High-temperature workshops require customized high-temperature resistant lithium batteries that can still discharge stably in environments above 60°C. High-temperature environments require enhanced heat dissipation (such as aluminum shell + air duct design, intelligent fans or liquid cooling). Low-temperature cold storage requires built-in heating film, insulation layer and low-temperature charging management strategy to ensure normal discharge and controlled charging at -20°C or even -30°C.
Operating condition adaptation. The power requirements for high-frequency continuous operation and intermittent operation are different, and customized solutions must match the working efficiency of the AGV. In scenarios involving bumpy roads, heavy-duty handling, and high-frequency start-stop, the battery cell connecting pieces, internal structure, and outer casing fixing points must be verified by vibration simulation or actual testing to prevent loosening, weld breakage, or structural fatigue after long-term operation.
AGVs are widely used in industrial settings, and the safety and reliability of lithium batteries directly affect equipment safety, personnel safety, and production continuity. This is especially true in special environments such as high temperatures, heavy loads, and explosion-proof conditions, where safety standards must meet industrial-grade requirements. Determining the safety of a customized solution requires comprehensive consideration from three aspects: protective design, testing and verification, and battery cell selection.
Protection design requires a layered approach. High-quality customized solutions employ a three-tiered protection structure: cell-module-pack, achieving safety redundancy. At the cell level, lithium iron phosphate cells (suitable for high-frequency, long-life applications) or ternary lithium cells (suitable for high-energy-density requirements) are prioritized, eliminating inferior cells. At the module level, heat dissipation design is optimized; liquid cooling or phase change materials are used for high-temperature scenarios, while a self-heating system is integrated for low-temperature scenarios.
Testing and verification are crucial for safety. Reputable manufacturers conduct 109 full-scenario tests on customized batteries, including safety tests (needle penetration, compression, short circuit, thermal runaway), environmental adaptability tests (high and low temperature cycling, vibration, drop), and electrical performance tests (rate charging and discharging, cycle life), etc. Each batch of products undergoes 100% inspection before shipment. When making a judgment, it is necessary to request relevant test reports from the manufacturer to avoid selecting solutions that have not undergone rigorous testing and to prevent potential safety hazards later.
In addition, attention should be paid to the battery's vibration and impact resistance. Collisions and bumps are inevitable during the operation of AGVs in industrial scenarios. Customized solutions need to pass relevant vibration tests. The battery pack shell uses high-strength materials and adds a buffer layer to ensure that there is no damage in the 1.5-meter drop test.
Cost control is crucial for AGV projects. The cost of customized lithium battery solutions includes not only upfront procurement costs but also ongoing maintenance and replacement costs. A comprehensive assessment of both short-term investment and long-term benefits is necessary to avoid falling into the "low-price trap."
Upfront procurement costs must match the project budget. A high-quality customized solution isn't necessarily the most expensive; rather, it should optimize the design based on project needs, reducing unnecessary costs. For example, small to medium-sized AGV projects can adopt a modular design, using standardized battery cell modules to reduce customization costs by 15%-20% and shorten the customization cycle to 7-15 days. When evaluating a solution, compare quotes from different manufacturers, focusing on the cost-effectiveness rather than simply pursuing the lowest price—low-priced solutions may use inferior battery cells and simplified protection designs, leading to future malfunctions and increased maintenance costs.
Long-term maintenance costs require close attention. Customized solutions with long cycle life and high stability can reduce battery replacement frequency, lower replacement costs, and reduce downtime losses.
Delivery timelines must align with the project schedule. AGV projects typically have defined implementation timelines. The delivery cycle for customized solutions must align with the project schedule. Routine parameter adjustments (such as minor capacity and size tweaks) require 15-20 days for sample delivery, while entirely new cell-level designs or BMS protocol development require 25-45 days. When making a decision, it's crucial to confirm the manufacturer's production capacity and delivery guarantees to avoid delays that could impact project launch.
Customizing AGV lithium batteries is not simply a matter of adjusting parameters; it involves a full-process service from needs assessment, solution design, sample testing, mass production, and after-sales maintenance. The manufacturer's technical strength and service level directly determine the success and long-term sustainability of the customized solution. To assess a manufacturer's strength and service, three core points should be considered:
First, technical strength. A high-quality manufacturer should possess cell-level customization capabilities, a professional R&D team, and the ability to optimize cell formulations, BMS algorithms, and structural designs according to project requirements. Simultaneously, they should have industrial-grade certifications such as ISO9001 and ISO14001, and their products should be certified by UN38.3, CE, and CB. They should also have their own testing center capable of conducting full-scenario testing and verification.
Second, full-process service capabilities. Customized solutions should provide "one-stop service," following up throughout the entire process from initial needs assessment and solution design to sample testing, mass production, on-site installation guidance, and post-installation maintenance. For example, manufacturers need to provide BMS protocol integration services during the R&D phase, simulate whole-machine signals for joint debugging tests, and issue test reports before mass production. Later, they need to establish a nationwide rapid response network to provide 72-hour on-site service and promptly resolve battery faults.
Finally, there is after-sales support. Comprehensive after-sales support can reduce project risks later on. When assessing this, it's crucial to pay attention to the manufacturer's after-sales policies, such as battery warranty periods, fault handling timelines, and repair/replacement procedures. Furthermore, reputable manufacturers will provide data-driven maintenance services, using cloud analytics platforms to monitor battery status in real time, enabling predictive maintenance and proactively preventing faults.
Determining whether a customized AGV lithium battery solution is suitable for your project hinges on five key dimensions: scenario adaptation, performance matching, safety and reliability, cost control, and comprehensive service. This involves considering the project's actual needs, budget, and schedule, avoiding blindly pursuing high parameters, low prices, or brand names, and instead choosing a "tailor-made" solution.
Currently, customized AGV lithium batteries are trending towards intelligence, lightweight design, and adaptability to extreme environments. A high-quality customized solution not only meets the AGV's power requirements but also reduces total lifecycle costs and enhances project competitiveness. We hope this methodology will help more AGV equipment manufacturers and end-user companies avoid selection pitfalls, choose the most suitable customized solution, maximize the value of AGV equipment, and contribute to the upgrading of intelligent manufacturing and warehouse logistics automation.

In simple terms, LEAD-WIN's customized AGV lithium battery solution process consists of four core stages: "requirements matching → solution design → prototyping and verification → mass production and delivery".
1. Requirements Assessment and Evaluation: Based on the basic parameters of the AGV provided by the customer (such as rated voltage, load, range requirements, installation size limitations, operating temperature, communication protocol, etc.), our technical team assesses its feasibility, clarifies the battery cell type (lithium iron phosphate/ternary lithium), BMS functional requirements, and preliminary structural direction.
2. Solution Design and Quotation: LEAD-WIN performs battery cell matching calculations, BMS selection/development, and 3D structural design (including handles, grips, pulleys, connector positions, etc.) based on the requirements, outputting solution drawings and details, and providing a quotation and delivery time.
3. Sample Production, Testing, and Verification: Engineering samples are first produced for charging/discharging, communication, vibration, high/low temperature, short circuit/overcurrent protection, and other tests. Once the customer receives the AGV lithium battery samples, verification begins to confirm whether the range, interface, protection logic, and SOC accuracy meet the on-site operating conditions.
4. Small batch/mass production and after-sales service: After verification, the BOM and process are locked and production is scheduled; aging equalization and full inspection are carried out before leaving the factory; after delivery, we provide a 5-year basic warranty or cycle life warranty for AGV lithium batteries (whichever comes first).
The delivery cycle for customized AGV lithium batteries depends primarily on the customized features and order quantity, and can generally be divided into the following stages:
Sample Stage: For routine parameter adjustments (such as standard voltage, capacity, and using the existing structure), samples can generally be completed in 7–15 days. If it involves entirely new structural designs, BMS communication protocol development (such as specific CAN/RS485 protocols), or adaptation to special environments (low temperature, explosion-proof, etc.), the cycle usually extends to 20–45 days.
Mass Production: After sample confirmation, small batch orders (such as 5-20 sets) are generally delivered within 15–30 days; large batch orders require a production schedule, typically around 20–45 days.
Standard/Inventory Products: If it only involves minor modifications to existing mature models, some manufacturers can ship in-stock items within 1–3 days, while fully customized standard products typically take 7–15 days to deliver.
Furthermore, if the project involves complex third-party certifications (such as UL, CE), stringent high and low temperature verification, or the procurement of imported battery cells, the delivery time will be correspondingly extended. In extreme cases (such as military-grade fully customized products), it may take more than 30 working days.
The differences are significant. Even for AGV lithium batteries of the same specifications (voltage, capacity), the prices from different brands can vary by several times, primarily depending on the following cost components:
1. Battery cell brand and grade;
2. Customization and manufacturing complexity;
3. BMS intelligence level;
4. Purchase quantity.
