Embodiment Construction

[0019] Embodiments of the lithium-ion battery thermal management system of the present invention: such as Figure 1-5 As shown, the system includes a battery box and a battery pack, an air duct system, a control system 6, and a heat exchange device. The battery box has a sealed inner cavity, and the battery pack includes two rows of battery cells. 30 are spaced in the front-to-rear direction and all are located in the lumen. The box body is composed of the front side plate 41, the left and right side plates 42, the rear side plate 43, the isolation plate 44, the air duct rear enclosure plate 45, the air duct side enclosure plate 46, the bottom plate 48 and the cover plate. Completely sealed.

[0020] The front part of the inner cavity of the battery box is provided with an air pump 1. The air pump 1 and the battery pack are separated from the front and the rear by the isolation plate 44. The space where the air pump 1 is located is the control area, and the space where the ba...

Abstract

The invention discloses a thermal management system for lithium-ion batteries. The system comprises a battery box body and a battery pack, wherein the battery box body comprises a sealed inner cavity; the battery pack comprises at least one group of battery cells; the battery cells are arranged at intervals along the forward-backward direction and are located in the inner cavity; an air pump is arranged at the front part of the inner cavity; an air intake duct which is communicated with the air pump is formed in one side, in the left-right direction, of one group of battery cells and an air return duct is formed in the other side; a radiator for emitting heat in the air intake duct to the outside is arranged on the battery box body; the radiated air in the air intake duct flows to the space in which the air pump is located through the air return duct; and the air intake duct and the air return duct are located in the sealed battery box body and are not communicated with the outside of the battery box body, so that corrosion of dust to the inside of the lithium-ion battery box can be avoided.

Description

technical field [0001] The invention relates to a lithium ion battery thermal management system. Background technique [0002] The charging and discharging process of lithium-ion power batteries will generate chemical reaction heat and resistance heat, especially with the development of large-unit capacity, high-specific energy lithium-ion batteries and the demand for high-current discharge in the power system, the heat generation effect of the battery Significantly, this poses a huge challenge to the thermal management technology of lithium-ion power batteries. The performance and life of lithium-ion power batteries are closely related to their working environment temperature. The increase in temperature not only greatly affects the performance and service life of lithium-ion power batteries, but also the thermal disturbance during the charging and discharging process may destroy the thermal stability of battery components. state, thereby triggering a series of exothermic ...
