Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0042] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses a battery shell and a battery system. A cover body covers a shell, so that battery packs are located in a sealed space, and primary protection is provided for battery packs. When the shell is impacted, a large amount of impact force can act on the side wall of the shell, and two ends of each reinforcing beam abut against the inner wall of the shell respectively, so that thestructural strength of the side wall of the shell is effectively enhanced, and therefore, the side wall of the shell is prevented from being seriously deformed due to the impact force; the impact force applied to the shell can be transferred and concentrated on the reinforcing beams, so that the impact force is transferred, and therefore, stress distribution on the shell is improved, and the structural integrity and good air tightness of the shell are ensured, the battery packs are always in a safe and stable environment, and the short circuit and even fire and explosion accidents of the battery packs due to the air tightness failure or piercing of the shell are avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery case and a battery system. Background technique [0002] For electric vehicles, the battery pack technology is very important. The stability and safety of the battery pack directly determine the performance of the electric vehicle. The stability and safe operation of the battery pack mainly depend on issues such as waterproof, anti-collision and cooling. In order to improve the safety of the battery pack and prevent the battery pack from being easily damaged due to impact, the battery pack is usually installed in the battery box; then the sealed battery box is installed on the car body. However, the structural strength of the traditional battery box is poor, and it is easy to be dented and deformed during the impact process, or even severely damaged, resulting in a short circuit or even a fire in the battery pack due to the failure of the airtightness of the b...
