For most industrial operation scenarios such as large-scale warehouses, port freight yards and manufacturing production lines, high material turnover efficiency puts forward higher requirements for the working continuity of handling equipment. Traditional fuel forklifts lead to extra emission control cost, while ordinary lead-acid forklifts need several hours of continuous charging, which cannot match the flexible energy supplement demand during short operation gaps. In this context, frequent fast charging as a highly efficient energy supplement solution is gradually widely adopted by operation teams, putting forward stricter requirements for the comprehensive performance of forklift hardware.

The core energy storage part of BYD lithium-ion forklift is equipped with specially optimized hardware configuration for frequent fast charging scenarios. The cell groups are arranged with reasonable structural gap, matching the independent liquid cooling temperature control system. During the whole fast charging process, the system can keep all cells working within the proper temperature range, and control the temperature difference between different cells at a reasonable level, avoiding local abnormal temperature rise caused by continuous high current input, which effectively reduces the extra loss of the energy storage system during repeated fast charging cycles.

For the high-voltage distribution system of the whole vehicle, the hardware of BYD lithium-ion forklift adopts industrial-grade high-current resistant connecting components, with antioxidant treatment on all connection contact surfaces. This design can effectively reduce line loss and abnormal heating when large current passes through in a short time, ensuring the stability of power transmission during frequent fast charging processes, and avoiding hidden safety risks caused by aging of circuit components after long-term use. The on-board charging port also adopts reinforced industrial design, which can maintain stable connection performance even after thousands of repeated plugging and unplugging operations in daily on-site use.

The embedded battery management system hardware adopts high-precision sampling modules, which can collect the voltage and temperature data of each cell in real time at high frequency. During the fast charging process, the system will dynamically adjust the current output curve according to the real state of each cell, avoiding excessive impact on the cell structure caused by continuous high current, so as to extend the service life of the whole energy storage system under frequent fast charging working conditions.

With the above targeted hardware optimization, BYD lithium-ion forklift can support 10 to 15 minutes of fast charging during the operation gap, and the supplemented power can support 2 to 3 hours of normal handling operation. This performance can fully meet the continuous operation demands of two-shift or three-shift on-site working modes, no need to configure extra spare batteries, which effectively reduces the whole life cycle operation cost for users. All relevant hardware components have passed multiple rounds of rigorous reliability tests, and can maintain stable operation performance in long-term frequent fast charging cycle scenarios, adapting to various high-load on-site operation demands.
