1.what kind of battery is used in electric forklift?
Electric forklift refers to the forklift that operates with electricity, and it can be divided into different types according to the different batteries used, and there are three kinds of batteries used in electric forklift in general:
1、Lead-acid battery
Lead-acid battery is one of the most traditional and commonly used types of batteries for electric forklifts, which uses lead plates and sulfuric acid electrolyte with low energy density and specific energy, but relatively low cost. The advantages of lead-acid batteries are that they are mature, stable, and have a long service life, while they can be cycled for many charge/discharge cycles. However, lead-acid batteries have the disadvantages of large weight, long charging time, fast self-discharge, etc., which affects the use of electric forklift efficiency and range.
2、Lithium battery
As an emerging battery technology, lithium battery is gradually emerging in the field of electric forklift. Lithium battery has high energy density and specific energy, compared with lead-acid batteries, has a lighter weight and longer use time. At the same time, lithium batteries also have the advantages of no memory effect, fast charging, etc., which can effectively improve the working efficiency of electric forklifts. However, the price of lithium battery is relatively high, and attention should be paid to preventing over-discharge and over-charging in the process of using, in order to avoid safety accidents.
3、Fuel cell
Fuel cell is also an emerging power source in electric forklift. Fuel cells utilize hydrogen and oxygen reaction to generate electricity, no need to charge, just add fuel. Fuel cell has the advantages of fast charging, zero emission, etc., which can meet the demand of electric forklift in long time and high intensity work. However, fuel cell technology is still not mature enough, and the construction of related equipment and fuel supply chain also has certain difficulties and costs.
2.lithium battery forklift trucks than lead-acid battery forklift advantages in which?
Lithium batteries and lead-acid batteries are two kinds of batteries used in electric forklifts, and the main advantages of lithium battery forklifts and lead-acid battery forklifts are as follows:
1、Fast charging speed
Lithium battery relies on its own chemical characteristics to meet the requirements of faster charging speed, from 10% to 100% charging time is only 2h, while lead-acid batteries from 20% to 100% charging time is 8-10h.
2, charging without memory
Lithium battery forklift charging without memory characteristics make the battery can be random, intermittent charging, without affecting the life of the user can be efficient use of work breaks and rest time for power supplementation, convenient for the user to carry out the work of the coordinator. Lead-acid batteries have charging memory, such as random or intermittent charging, serious damage to the battery, shortening the battery life, so generally need to be 20%-100% full full discharge, regular equalization charging.
3、Long service life
Lead-acid batteries average 1200 times (operating hours of about 6000h) cycle life, lithium iron phosphate battery has 4000 + times (operating hours of about 24000h) cycle life. In actual use, lithium iron phosphate battery still has more than 65% capacity after 4000 times, while lead-acid battery has less than 50% capacity after 1200 times.
4、Wide discharge temperature range
In the -20 degrees to 60 degrees between the high temperature or low temperature, lithium batteries have good discharge performance, in the case of -20 degrees, lithium battery discharge efficiency of 80% to 90%, while the lead-acid battery discharge efficiency is less than 30%.
