Abstract

In the daily operation of third-party logistics and distribution centers, frequent and multi-shift continuous operations are required. This article, in combination with the actual scenarios of logistics operations, deeply analyzes how lithium batteries for forklifts can meet the operational demands, providing practical directions for enterprise upgrades.

With the rapid development of the e-commerce industry, the business volume of logistics and distribution centers has grown explosively, and the efficiency of goods turnover has become one of the core competencies of enterprises. In actual operation, logistics centers need to implement a multi-shift operation mode of "two shifts" or even "three shifts" around the four core links of goods loading and unloading, sorting, shelving and outbound. Moreover, the operation frequency of each link is extremely high. Take the sorting link as an example, the daily sorting order volume of some large distribution centers exceeds 100,000 orders. Forklifts need to continuously shuttle between the shelves and the sorting area, with an average of more than 50 starts and stops per hour.

However, the lead-acid batteries commonly used in traditional forklifts are difficult to meet the demands of such high-intensity operations. On the one hand, the charging time of lead-acid batteries is as long as 8 to 10 hours, and the range after charging is limited. Usually, they can only support 8 hours of operation in a single shift. If enterprises want to meet the continuous operation of multiple shifts, they need to provide an additional 2 to 3 sets of spare batteries. This not only increases the cost of equipment procurement but also requires reserving dedicated space for battery replacement and storage. Occupy the precious storage area of the logistics center; On the other hand, the service life of lead-acid batteries is relatively short, averaging only 2 to 3 years. Moreover, the maintenance cost in the later stage is high, requiring regular replenishment of electrolyte and cleaning of battery terminals. Frequent maintenance operations further affect the effective operation time of forklifts, leading to a decline in the overall operational efficiency of the logistics center.

ⅠThe core advantages of lithium batteries for forklifts: Fast charging to support continuous operation

In response to the operational pain points of third-party logistics and distribution centers, lithium batteries for forklifts, with their fast charging characteristics, have become an ideal choice for addressing continuous operation demands. Compared with traditional lead-acid batteries, the charging efficiency of lithium batteries used in forklifts has been significantly improved. Lithium batteries with fast charging technology can be charged to over 80% of their capacity in just 1-2 hours, and the battery life after charging can reach 12-16 hours, which can directly support continuous operation in two shifts without the need for frequent battery replacement.

In addition to the advantage of fast charging, lithium batteries for forklifts also have the characteristics of long lifespan and low maintenance cost. The service life of high-quality lithium batteries for forklifts can reach 5 to 8 years, which is 2 to 3 times that of lead-acid batteries. During use, there is no need to replenish electrolyte or clean the terminals. Only regular appearance checks are required, significantly reducing the impact of maintenance work on forklift operation. Meanwhile, lithium batteries have a higher energy density and a stronger endurance under the same weight, which can reduce the weight of the forklift itself and enhance its operational flexibility. Especially in narrow shelf aisles, the turning radius of lithium battery forklifts is smaller, further improving operational efficiency.

Ⅱ. The compatibility of lithium batteries for forklifts throughout the entire logistics operation process

In the four core links of goods loading and unloading, sorting, shelving and outbound in third-party logistics and distribution centers, lithium batteries for forklifts can all play a significant role and meet the operation requirements of different scenarios.

During the loading and unloading of goods, forklifts need to frequently start and stop, and lift and lower the forks, which requires a relatively high instantaneous discharge capacity of the power source. Lithium batteries have excellent high-current discharge characteristics, which can quickly respond to the power demands of forklifts, ensuring the stability of fork lifting and vehicle start and stop, avoiding the risk of goods falling due to insufficient power, and at the same time reducing energy consumption loss during vehicle start-up, further extending the driving range.

During the sorting process, forklifts need to shuttle between dense shelves and sorting tables, with complex operation paths and frequent turns. Lithium battery forklifts are lighter in weight, and their steering systems are more flexible in operation. They can quickly adapt to complex working paths, reduce time loss during steering, and improve sorting efficiency. Meanwhile, the low-noise feature of lithium batteries can also improve the working environment in the sorting area and reduce the fatigue of employees.

During the shelving and outbound processes, forklifts need to lift goods to high shelves for a long time (some shelves are over 10 meters high), which requires a high continuous output capacity of the power source. Lithium batteries have stronger voltage stability. Under long-term high-load operation, the voltage drop is small, which can ensure the stable operation of the forklift lifting mechanism, avoid the decrease in lifting speed caused by voltage fluctuations, and guarantee the continuity of loading and unloading operations.

Ⅲ. Precautions for Logistics Enterprises when Choosing Lithium Batteries for Forklifts

Although lithium batteries for forklifts have significant advantages, logistics enterprises still need to pay attention to the following points during the selection and application process to ensure equipment compatibility and operational safety.

First of all, the appropriate battery capacity should be selected based on the intensity of the operation. The operation frequency and forklift mileage of different logistics centers vary. Enterprises should calculate the required battery capacity by combining data such as daily operation time and average forklift mileage to avoid interruption of battery life due to insufficient capacity or cost waste due to excess capacity. Secondly, it is necessary to be equipped with high-quality fast charging devices and charging management systems. Poor-quality fast charging devices may cause battery overheating, shortened lifespan, and even pose safety hazards. Therefore, enterprises should select original fast-charging equipment that matches the brand of lithium batteries and be equipped with a charging management system featuring overcharge protection, over-temperature protection, and short-circuit protection functions to monitor the battery charging status in real time and ensure the safety and stability of the charging process.

Finally, it is necessary to enhance the operational training for employees. Some employees may still retain the operating habits of lead-acid battery forklifts, such as overcharging for a long time and randomly piling up miscellaneous items during charging. These behaviors may affect the service life and safety of lithium batteries. Enterprises should organize specialized training sessions to explain the operation norms, charging precautions and daily maintenance methods of lithium battery forklifts, and enhance employees' awareness of safe operation.

Ⅳ. Conclusion

Under the high-frequency and multi-shift operation mode of third-party logistics and distribution centers, the stability and endurance of the power source directly determine the operational efficiency of the enterprise. Lithium batteries for forklifts, with their advantages of fast charging, long lifespan and low maintenance costs, have effectively broken through the endurance bottleneck of traditional lead-acid batteries, providing reliable support for logistics enterprises to achieve continuous operations.
