Embodiment approach

[0040]In this embodiment, the inner structures of the A box 111 and the B box 112 are the same, and the only difference is the arrangement of positive and negative electrodes of the battery modules. The implementation method is as follows, the battery box 30 is placed in the bottom case 20 and positioned through the ribs 23, after the battery module 40 is loaded into the battery box 30, the battery modules are connected in series and parallel with the aluminum row 50 to form a battery pack, and the battery box 30 is further The sealing groove is put into the sealing ring and locked with the top cover 12 to achieve the sealing effect, and the sealing level of the whole box reaches IP67. A cover plate 11 is installed above the top cover 12 for positioning and heat dissipation. which is, figure 1 and figure 2 The complete box shown includes two battery boxes sharing a single controller box 120 . Such as figure 1 As shown, the controller box 120 includes a controller box base ...

Abstract

The invention discloses a battery case. The battery case comprises a bottom housing, a battery box and a top cover, wherein the bottom housing comprises a side plate of the bottom housing and a bottomplate of the bottom housing; a fan is arranged on the side plate; the battery box is fixed in the bottom housing; the battery box is used for placing a battery module; a heat-dissipating air flue isarranged on the battery box; the fan sucks heat in the battery box through the heat-dissipating air flue; and the top cover covers the battery box and is used for sealing the battery box. The technical problem that the existing battery case has a complex heat-dissipating system is solved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery box. Background technique [0002] Among the current mainstream lithium-ion power batteries, lithium titanate batteries are gradually gaining favor in the market due to their advantages such as long life, wide temperature resistance, high reliability, and multi-function. However, the energy density of lithium titanate batteries is low. For electric vehicles, a single battery cell cannot provide sufficient capacity and energy. Many single cells must be connected in series and parallel to meet the capacity and energy requirements. At present, in the field of new energy battery boxes, metal battery boxes made of alloy are mostly used. A large number of single batteries are placed in a closed metal battery box, which will inevitably cause problems such as heat concentration and increased mass. The heat dissipation method also chooses water cooling, which requires an additional wat...
