The invention relates to an intelligent cooling device for a large-capacity lithium-ion battery power system and aims to solve the problem an existing intelligent cooling device for a lithium-ion battery power system cannot achieve high-efficiency cooling due to a simple structure. The device comprises a motor which is provided with a rotating shaft, the other end of the rotating shaft is fixedlyprovided with a main propeller, an incomplete gear fixedly sleeves the rotating shaft, and the incomplete gear is alternately engaged with two groups of parallel teeth in a ring gear. According to thedevice, by adding a combined structure of a temperature sensor and a cooling component and setting the temperature sensor, the temperature in the lithium-ion battery power system can be effectively monitored in real time, when a condition that the temperature exceeds a normal range is monitored, a circuit is turned on to control the cooling component to work, and therefore, the effect of coolingis achieved. The structural design is reasonable, the effect of the intelligent control of a cooling process is achieved, the effect of efficient cooling can be achieved, and so the device has a highpractical value in practical applications.
Description
technical field [0001] The invention relates to the technical field of lithium-ion battery power systems, in particular to an intelligent cooling device for large-capacity lithium-ion battery power systems. Background technique [0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes; during charging, Li+ deintercalates from the positive electrode, intercalates through the electrolyte into the negative electrode, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. With the advancement of science and technology, lithium-ion batteries are used in large-capacity forms in urban subway tunnels, highway tunnels, mine earthworks, and traction locomotive power systems for mineral transportation. The sign...
