Comparison and explanation of lithium battery system structure of S14JW and S20JW stacker truck

In industrial warehousing and logistics scenarios, the lithium battery system of a stacker directly affects the battery life, operating stability, and adaptability of the equipment. Although the lithium battery systems of the S14JW and S20JW stackers belong to the same type of application scenario, there are specific differences in structural design. The following will be compared and explained from multiple dimensions.

Cell and module configuration

The lithium battery systems of the two stackers have their own emphasis on battery cell selection and module configuration. The S14JW lithium battery system adopts a compact battery cell arrangement, and the overall volume of the module is small. The single module capacity adapts to the small and medium load operation requirements of the equipment. The modules are combined with lightweight connectors to take into account the structural strength and weight reduction requirements. The S20JW lithium battery system uses higher-capacity batteries, with fewer modules but stronger single-module energy storage. It is suitable for large-load continuous operation scenarios. The packaging structure of the module pays more attention to impact resistance and responds to vibration interference in complex storage environments.

Battery management system architecture

The design direction of the battery management system structure of the two is different. S14JW's battery management system adopts an integrated architecture, which integrates data collection, balance control and protection modules in a Control Unit. The circuit layout is simple and takes up little space. It is suitable for the compact installation environment inside the equipment. It can quickly detect the overall operating status during daily maintenance. S20JW's battery management system adopts a distributed architecture. The data collection modules are scattered near each module. The main Control Unit processes information centrally. This design can more accurately monitor the operating parameters of each module, adapt to the fine management requirements of large-capacity lithium battery systems, and adjust the output strategy more timely when the load fluctuates.

Heat dissipation protection system

The difference in heat dissipation structure is the key to adapting the two lithium battery systems to different operating intensities. The S14JW lithium battery system adopts a passive heat dissipation-based structure. The heat dissipation fins of the module shell cooperate with the natural ventilation channel inside the equipment to meet the heat dissipation needs under small and medium loads. The structure is simple and the maintenance cost is low. The S20JW lithium battery system is equipped with active heat dissipation components. Small heat dissipation fans are set between the modules, and the thermal conductive silicone pad is used to improve the heat conduction efficiency. At the same time, the protective shell has better dust and waterproof performance, which can ensure the stable operation of the lithium battery system under high load continuous operation and harsh storage environments.

installation adaptation layout

The installation layout of the two lithium battery systems adapts to the structural design of different models. The S14JW lithium battery system adopts a modular drawer installation structure, which takes up less space at the end of the equipment, which is convenient for quick module replacement. It is suitable for operation scenarios that require frequent scheduling and quick replenishment. The S20JW lithium battery system adopts a fixed overall installation layout, which fits closely with the frame structure to improve the overall stability and adapt to the center of gravity of large-load stackers. After installation, the overall operation of the equipment is more smooth.

Through the comparison of the above dimensions, it can be seen that the lithium battery system structure design of the S14JW and S20JW stackers is based on their respective operating scenarios. Users can choose the appropriate stacker model and lithium battery system according to the load intensity, operating frequency and environmental conditions of their own warehousing operations.
