Against the backdrop of global low-carbon transformation in industrial logistics, electric forklifts have been widely adopted in warehouse, port and manufacturing scenarios. Lithium-ion packs have gradually become the mainstream power source for electric forklifts due to their high energy density, long cycle life and no need for frequent maintenance. As the core control component connected to every cell of the lithium pack, the battery management system directly determines the operation safety, service life and comprehensive performance of the whole power system, so it needs to meet targeted requirements different from ordinary consumer energy storage BMS.

The first core requirement is full-dimensional safety protection capability. Forklifts often face frequent start-stop, sudden load changes and long-time continuous operation in daily work. The BMS for forklift lithium packs needs to collect real-time voltage, current and temperature data of each single cell, and set reasonable protection thresholds for over-charge, over-discharge, over-current, over-temperature and low-temperature working conditions, so as to cut off the circuit in time when abnormal state occurs, and avoid potential safety risks caused by improper operation or harsh external environment.

The second key requirement is strong working condition adaptability. Forklifts may work in extreme scenarios ranging from low-temperature cold storage below zero degrees to high-temperature open yards in summer. The qualified BMS needs to support active cell balancing function, low-temperature pre-heating control logic and dynamic output power adjustment mechanism, which can balance the inconsistency between different cells during long-term operation, and automatically adjust the power output according to the current load of the forklift, so as to extend the overall cycle life of the lithium pack properly.

The third practical requirement is convenient operation and maintenance traceability function. The BMS should support local data storage and real-time data transmission, which can record complete data of each charging and discharging cycle, and store clear fault logs for later query. Operation and maintenance personnel can judge the health status of the lithium pack through the data uploaded by BMS, arrange maintenance plans in advance, and reduce the unplanned shutdown time of forklifts.

Jianshu New Energy focuses on BYD electric forklifts, and all supporting lithium packs are equipped with BMS systems that fully meet the above multi-dimensional requirements, to provide stable and reliable material handling power solutions for industrial users.
