What are the advantages of lithium battery forklifts compared to lead-acid battery forklifts?
Lithium batteries are used in a wide range of fields. In addition to automobiles and electric vehicles, UPS power supplies, energy storage, computer room communications, forklifts, iron towers, base stations and other scenarios can be applied. Compared with lead-acid batteries, the advantages of using lithium batteries on forklifts are more obvious. With the advancement of forklift electrification, lithium batteries are becoming the biggest competitor of traditional lead-acid batteries.
At present, most lithium battery vehicles are used in commuter vehicles, electric maintenance vehicles, sanitation cleaning vehicles and short-term buses. However, since most of the forklifts operate in the factory area, the work intensity and environment are fixed, and the work intensity is generally strong. Therefore, many advantages of lithium batteries can be reflected in electric forklifts.
1. Fast charging speed
Lithium-ion batteries rely on their own chemical characteristics to meet faster charging speed requirements, and the charging time from 10% to 100% only takes 2 hours. It takes 8-10 hours to charge a lead-acid battery from 20% to 100%.
2. Charging without memory
The non-memory feature of the forklift lithium battery allows the battery to be charged randomly and intermittently without affecting its lifespan. Users can efficiently use work breaks and rest time to replenish power, which is convenient for users to coordinate their work. In the process of charging and discharging, the energy loss of the lithium battery is small, and the rated output power is always maintained regardless of the remaining power of the lithium battery.
Lead-acid batteries have charging memory, such as random or intermittent charging, which will seriously damage the battery and shorten the battery life. The correct charge and discharge operation of lead-acid batteries is: 20%-100% full charge and discharge; regular equalization charge. It is inconvenient for users to coordinate work.
3. Long service life
Lead-acid batteries have an average cycle life of 1,200 cycles (about 6,000 hours of operation), while lithium iron phosphate batteries have a cycle life of 4,000+ cycles (about 24,000 hours of operation). In actual use, the lithium iron phosphate battery still has more than 65% of its capacity after being used for 4,000+ times, while the capacity of the lead-acid battery is less than 50% after being used for 1,200 times.
4. Wide discharge temperature range
At high or low temperatures between -20 degrees and 60 degrees, lithium batteries have good discharge performance. At -20 degrees, the discharge efficiency of lithium batteries is 80% to 90%, while lead-acid batteries discharge The efficiency is less than 30%.
5. Improve operational efficiency
Lithium battery fast charging mode, 1-3 hours fast charging mode is suitable for multi-shift operations. It is ready to charge and use without the time and safety risks of battery replacement, and the power is stronger, which can completely replace internal combustion forklifts. Technology monitors the status of forklifts and batteries to improve the management level of forklifts.
6. Lithium battery with special performance
Compared with lead-acid batteries, the use of lithium batteries in forklifts can also derive a variety of lithium batteries with special properties by changing the formula, providing a variety of power supports for the innovative design of forklifts. If it can be made into a low-temperature lithium battery, its performance cannot be achieved by lead-acid batteries.
