Abstract

The invention relates to a battery inner box and a battery temperature control box employing the battery inner box. The battery inner box comprises an inner box cover plate, an inner box bottom plate, and inner box side plates which are arranged between the inner box cover plate and the inner box bottom plate. The battery inner box is characterized in that the inner box cover plate, the inner box bottom plate and the inner box side plates enclose a closed storage battery accommodation cavity which is used for accommodating a corresponding storage battery; the inner box cover plate is made of a heat conduction material; and outer heat conduction fins and inner heat conduction fins, which are backward, are respectively arranged on the top and bottom surfaces of the inner box cover plate. The invention provides the battery inner box which can prevent entry of damp air and has a good radiating effect.

Description

technical field

[0001] The invention relates to the technical field of power batteries, in particular to a battery inner box for a storage battery and a battery temperature control box using the battery inner box. Background technique

[0002] With the continuous rise of oil prices, in order to reduce dependence on oil resources, governments of various countries vigorously advocate energy-saving and new energy technologies, so that electric vehicles have been vigorously promoted. The huge demand for electric vehicles has promoted the continuous progress of battery technology. At present, lithium-ion batteries are Its excellent performance is generally recognized by electric vehicle manufacturers, and is used in some mass-produced models, such as Japan's LEAF, GM's VOLT, etc. The Chinese government promotes the demonstration operation of electric vehicles in some cities through the "Ten Cities, Thousand Vehicles" policy . However, because lithium-ion batteries, especially li...
