Problems solved by technology

The output terminals are only connected by bolts and nuts, which not only cannot ensure the safety of insulation, but also tends to loosen due to vehicle vibration, resulting in connection failure, which affects the overall life and safety of the power battery and shortens the driving time of the vehicle
Moreover, the power battery assembly process of this structure is cumbersome, and the installation and maintenance costs are high

Abstract

The invention discloses an insulating device and a battery module output device with the same. The insulating device is located at the end part of a copper bar between adjacent battery modules, and comprises a base and an insulating cover, wherein the base is used for being fixedly connected with one battery module; and the insulating cover is detachably connected with the base and is provided with an insulating body which is used for covering a copper bar connection structure. After the battery modules, the copper bar and the insulating device are arranged, no high-voltage exposure can be ensured; the insulating safety is ensured; and reliable connection of the connection structure between the battery modules is ensured. Furthermore, the insulating cover is detachably connected with the base, so that the disassembly and assembly convenience between the battery modules can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery systems, in particular to an insulating device and a battery module output device provided with the insulating device. Background technique [0002] In hybrid electric vehicles and electric vehicles, the power battery system includes a battery box and a battery module. The battery module is arranged and installed inside the battery box and is the core component of the power battery system. Generally speaking, in order to meet the requirements of the mileage of the vehicle and the driving motor, multiple battery modules need to be connected in series so that the power battery can achieve sufficient power and voltage. [0003] Most of the power batteries in the prior art use bolts and nuts for their output terminals to realize series and parallel connection between the battery modules, so as to assemble and manufacture a large-capacity power battery. The output terminals are only c...
