Problems solved by technology

The heat accumulation of the battery itself plus the heat radiated by the forklift will eventually cause the lithium battery to quickly enter the high temperature protection state and make the vehicle unable to work
Furthermore, according to the lithium battery performance test, a set of batteries can be charged and discharged for more than 2000-3000 times at room temperature, while at high temperature (55°C), its cycle life can only reach 800-1000 times

Abstract

The invention relates to a lithium battery forklift cooling system. The system comprises a frame body, a vehicle body front plate, a vehicle body rear plate, a vehicle body left side plate, a vehiclebody right side plate and a tail frame bottom plate, a first space is formed between the vehicle body front plate and the vehicle body rear plate, a second space is formed between the vehicle body rear plate and the tail frame bottom plate, an air inlet is formed in the vehicle body right side plate, an air outlet is formed in the vehicle body left side plate, the air inlet, the first space and the air outlet form a first cooling channel in the transverse direction of a vehicle body, the air inlet, the second space and the air outlet form a second cooling channel in the transverse direction ofthe vehicle body, an air inlet gap is formed in the vehicle body front plate, a heat removal gap is formed in the vehicle body rear plate, the air inlet gap, the first space and the heat removable gap form a cooling channel in the longitudinal direction of the vehicle body. In this way, the transverse cooling channel and the longitudinal cooling channel improve the cooling capacity of a lithium battery; by means of the structure that the lithium battery and a vehicle body heat source are separated, the influence of the vehicle body heat source on lithium battery temperature rise is lowered.

Description

Technical field [0001] The invention relates to a lithium battery forklift heat dissipation system. Background technique [0002] Nowadays, the new energy vehicle market is developing rapidly, and the application of power lithium-ion battery (hereinafter referred to as lithium battery) technology in the automotive industry is also becoming popular. The automotive industry has gradually matured research and application of thermal performance control technology for lithium batteries. A typical approach is a liquid cooling system, which uses battery pack liquid circulation to absorb heat to improve the battery’s heat dissipation performance to ensure that the battery is in a more suitable temperature range. Work inside, thereby ensuring the safety of battery application and prolonging the service life of the battery. In the forklift industry, due to the constraints of the forklift's own structure, performance and system cost, it is currently not possible to apply thermal performan...
