Problems solved by technology

[0004] A large number of battery pack vibration test results also show that when the MSD is installed on the upper case, due to the thinner upper case and insufficient structural strength, the MSD will resonate, resulting in fatigue fractures at the joint between the upper case and the MSD, causing vibration test failed

Abstract

The invention provides an electric vehicle and a battery pack casing thereof. An MSD (manual service disconnector) is mounted on a lower casing of the battery pack casing through an adapting support;the structural strength of an upper casing is unaffected, and the requirements on mounting strength and space arrangement can be met. The battery pack casing includes the lower casing and the upper casing covering each other; the lower casing has a receiving cavity to receive a battery pack; the battery pack is connected with the MSD; the battery pack casing also includes the adapting support formounting the MSD; the adapting support is connected with the lower casing, and the MSD is supported above the upper casing. The MSD is adapted to the lower casing through the adapting support; the strength of the upper casing is unaffected. The MSD can also be supported above the upper casing within an operation range of an interior maintenance port; the MSD is actuated via the interior maintenances port; the requirement on space arrangement is satisfied at the premise of satisfying the requirement of the MSD upon mounting strength.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle and a battery pack casing thereof. Background technique [0002] Manual Service Disconnector (MSD for short), as a protection device for high-voltage system safety and maintenance personnel, is widely used in the power battery pack system of new energy vehicles. When the battery pack is being maintained on the high-voltage system, it can disconnect the high-voltage connection to protect the safety of maintenance personnel; when there is a risk of short circuit in the high-voltage system, its built-in fuse will blow to protect the safety of the high-voltage system. [0003] Due to the space layout requirements of the vehicle, the power battery pack is often installed at the lower part of the car chassis. Considering the convenience of battery pack maintenance, the MSD is generally installed on the upper shell of the battery pack, and the MSD is comple...
