Problems solved by technology

[0003] The voltage specifications of the battery packs in the prior art are basically below 60V, and it is difficult to achieve a specification higher than 60V. The reason is that the battery pack will generate a lot of heat during the charging and discharging process. Emission will affect the service life of the battery pack, and even cause safety accidents, and the higher the voltage specification of the battery pack, the higher the heat generated during charging and discharging. Therefore, in the prior art, the battery pack cannot be well overcome The heat dissipation problem, so it is difficult to make a battery pack higher than 60V
[0004] Such as the application number 201410534172.7 in the Chinese patent titled "Battery Pack" also mentioned this problem, but the battery pack casing used to solve this technical problem has a large volume and poor practicability

Abstract

The invention discloses a battery pack, which comprises an upper PCB fixing plate, a lower PCB fixing plate, and two battery units connected in series between the upper and lower PCB fixing plates, and the battery units include a plurality of rectangular arrays. Arranged batteries, the placement direction of each adjacent two batteries is opposite, and the two ends of the battery are provided with conductive sheets that connect the batteries in each battery unit in series, and the front and rear ends of the battery are fixed with rectangular Skeleton, the frame is provided with clamping holes for fixing the end of the battery, and a heat dissipation hole is provided at the center of each adjacent four rectangularly arranged clamping holes on the skeleton, and the heat dissipation holes are arranged on the skeleton to connect with the batteries arranged in a rectangular shape. The passages formed between the batteries under the four adjacent rectangular arrays together form a heat dissipation passage, which greatly increases the heat dissipation performance of the battery pack and provides a prerequisite for the large-scale battery pack to work.

Description

technical field [0001] The present invention relates to the battery field, and more specifically, it relates to a battery pack. Background technique [0002] Existing battery packs are made of multiple single cells or capacitors connected in parallel to form a module, and then multiple modules are connected in series and parallel to form a battery pack with a certain voltage and capacity, and are made in a sealed box. [0003] The voltage specifications of the battery packs in the prior art are basically below 60V, and it is difficult to achieve a specification higher than 60V. The reason is that the battery pack will generate a lot of heat during the charging and discharging process. Emission will affect the service life of the battery pack, and even cause safety accidents, and the higher the voltage specification of the battery pack, the higher the heat generated during charging and discharging. Therefore, in the prior art, the battery pack cannot be well overcome The hea...
