Electric forklifts have the advantages of zero emissions, strong power and low noise, and have begun to replace traditional fuel forklifts. However, there is an important problem to be solved in the practical application of electric forklifts, that is, the problem of charging.

　　Electric forklifts generally use lead-acid batteries or lithium batteries as power sources. We are quite clear about the charging methods and characteristics of traditional lead-acid batteries, but as the power source of the new generation of electric forklifts, what is the charging of lithium battery?

　　Lithium batteries have safe and stable CAN communication, can be charged intelligently, and do not need to be replaced.

　　Unlike lead-acid batteries, lithium batteries are left in the forklift during the charging process and are charged through the plug connection. Therefore, the charging infrastructure required for lithium batteries can save the space for temporary storage of batteries.

　　The charging and discharging of lithium batteries are controlled by the battery management system (BMS), while lead-acid batteries are simply voltage monitoring. The powerful BMS can make "plug and charge" a reality. Just drive the forklift to the charging station, and through CAN detection and communication, the charger can automatically select the appropriate charging mode according to the status of the lithium battery without setting other settings.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Compared with lead-acid batteries, lithium batteries have the advantages of long life, environmental protection, light weight, light weight, reliability and stability, and will surely become the standard configuration of electric forklifts in the future.
