Description

Technical Field

[0001] The present application relates to the technical field of electric forklifts, and more specifically, to an electric forklift including a fire extinguishing system and a fire extinguishing method. Background Art

[0002] As an important handling tool in modern logistics and warehousing, electric forklifts have the advantages of no emissions, low noise, and low maintenance costs. At present, lithium-ion batteries are also widely used in the field of electric forklift batteries due to their high energy density. However, with the continuous application of lithium-ion batteries, fires and explosions occur frequently, posing a serious threat to the personal safety and property safety of electric forklift operators.

[0003] Lithium-ion batteries are a closed system containing high-energy materials, flammable substances and flame retardants. Lithium-ion batteries only exchange energy with the outside world, not substances. The combustibles in lithium-ion battery fires mainly include electrolytes and combustible gases produced by thermal runaway reactions, and the thermal runaway reactions of lithium-ion batteries can continuously produce combustible gases and heat. When a thermal runaway fire occurs in a lithium-ion battery, external fire extinguishing agents can only extinguish the fire outside the battery, but cannot enter the battery to block the thermal runaway reaction. Combustible gases can still be released from the battery continuously, and the battery temperature can still rise again, with a high risk of re-ignition.

[0004] The existing measure to improve the safety of lithium-ion batteries is to add flame retardants to the electrolyte. However, this measure has many limitations. First, in order not to affect the performance of lithium-ion batteries, too much flame retardant cannot be added, and the flame retardant effect is general; second, flame retardants cannot inhibit thermal runaway gas production reactions. Usually, when electric forklift lithium-ion batteries have thermal runaway fires, they are prone to operating problems, battery disassembly difficulties, and fires that are difficult to extinguish. Summary of the invention
