Battery system and vehicle

Abstract

The invention relates to the technical field of batteries, and provides a battery system and a vehicle, the battery system comprises at least two battery boxes, battery modules and a high-voltage box, the high-voltage box is arranged in one of the battery boxes, and the battery module is arranged in each battery box; the battery modules are connected in series, the positive electrode of the battery module at the head end is electrically connected with the battery positive interface of the high-voltage box, and the negative electrode of the battery module at the tail end is electrically connected with the battery negative interface of the high-voltage box; the battery boxes are stacked together in the vertical direction, and threading holes are formed in the wall surfaces of the close end parts of the adjacent battery boxes, and are arranged to allow electric wires for connecting the battery modules positioned in the adjacent battery boxes to pass through. According to the arrangement, the high-voltage box and the connecting wire are arranged in the battery box, a waterproof plug and a waterproof socket are not needed, and the problems of high production cost and poor reliability caused by the fact that a battery system in the prior art needs to be provided with the waterproof plug and the waterproof socket are solved.

Description

technical field [0001] The present invention relates to the technical field of batteries, and in particular, to a battery system and a vehicle. Background technique [0002] With the development of commercial vehicles towards electrification, commercial vehicle batteries are also developing rapidly. Due to the large energy consumption requirements of commercial vehicles, in order to meet their large power requirements, multi-layer battery boxes are generally stacked to connect multiple batteries and high-voltage boxes to form a battery system. [0003] In the prior art, wires are generally used to connect adjacent batteries together outside the batteries and then connect to the high-voltage box. In order to meet the requirements of waterproof and dustproof, it is necessary to equip the wires with waterproof plugs and waterproof sockets. The waterproof plugs and waterproof sockets are expensive and easy to fail, resulting in high production costs of the battery system and po...
