Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model aims to provide a battery system suitable for a low-temperature environment, which can keep the working environment of a battery constant under the low-temperature condition, and further can ensure the service performance of the battery.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

As shown in fig. 1, the battery system suitable for a low-temperature environment provided by the present utility model includes: a housing 1, a battery module 2, a heat conduction pipe 4 and a plurality of vacuum bags 3.

The heat conductive pipe 4 is wound around the battery module 2. A plurality of vacuum bags 3 are provided on the wall surface of the housing 1, respectively. An adhesive-bondable process is used between the two vacuum cells 3 so that the plurality of vacuum cells 3 form a space for placing the battery module 2. At this time, the working environment of the battery module 2 is the space formed by the vacuum bag 3, and the vacuum bag 3 not only has the heat insulation effect, but also can provide anti-collision protection. The heat conductive pipe 4 is filled with a heat conductive medium.

In a specific application, the entire vacuum bladder 3 may be adhered to the wall surface of the housing 1 using an adhesive. A clamping groove may be provided on each wall surface of the housing 1 so that the edge of the vacuum bag 3 is placed in the clamping groove, in which case, only the center of gravity of the vacuum bag 3 needs to be adhered to the wall surface of the housing 1.

Further, in order to enable the medium in the heat conduction pipe 4 to quickly absorb heat generated when the battery is operated, it is preferable that the heat conduction medium used is water.

Further, when the battery is not operated and is in a low temperature environment for a long period of time, condensation water droplets are easily formed by cooling in the space formed by the vacuum bladder 3 for placing the battery module 2, and at this time, the workability of the battery module 2 is affected, and on the basis of this, the present utility model may be further provided with a drying layer or drying strip 5 for absorbing moisture.

Wherein, when a drying layer is provided, the drying layer may be adhered to the vacuum bladder 3.

When the drying strips 5 are arranged, in order to further reduce the volume of the battery system, the surface of the vacuum bag 3 can be provided in a wavy shape, and the drying strips 5 are attached to the concave parts on the surface of the vacuum bag 3, and the specific arrangement mode is shown in fig. 2.

Based on the above description, in the practical application process, the heat conducting tube can be heated during the operation of the battery to quickly reduce the core temperature of the battery model, and when the battery does not operate, the heat in the heat conducting tube is slowly released, so that constant heat can be provided for the battery in a low-temperature environment, and the vacuum bag can effectively isolate the low-temperature environment and effectively prevent internal and external heat exchange. The drying layer or the drying strip is used, so that the battery module always works in a drying environment, and the danger caused by condensation can be effectively avoided.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to assist in understanding the methods of the present utility model and the core ideas thereof; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings. In view of the foregoing, this description should not be construed as limiting the utility model.
