New energy automobile battery pack

Abstract

The invention discloses a new energy automobile battery pack, and relates to the field of new energy automobiles. The new energy automobile battery pack comprises a battery pack body, the surface of the battery pack body is fixedly connected with a fixing frame, the surface of the fixing frame is fixedly connected with a protection device, the upper surface of the battery pack body is fixedly provided with a terminal, the surface of the terminal is clamped with a series copper bar, a waterproof device is arranged on the surface of the battery pack body, the protective device comprises a fixed seat, a protective spring is fixedly connected to the inner wall of the fixed seat, a stop block is fixedly connected to one end of the protective spring and is in sliding connection with the inner wall of the fixed seat, a sliding rod is fixedly connected to the inner wall of the stop block, a connecting block is fixedly connected to the end, away from the fixed seat, of the sliding rod, a main protection plate is fixedly connected to the upper surface of the connecting block, and an auxiliary protection plate is fixedly connected to the side, away from the sliding rod, of the connecting block. According to the new energy automobile battery pack, by arranging the protection device, when the periphery of the battery pack needs to be protected, the main protection plate and the auxiliary protection plate can effectively block external factors.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle battery pack. Background technique [0002] The new energy vehicle battery pack consists of multiple batteries stacked in series. A typical battery pack has about 96 cells, which can produce a total voltage of over 400V for a Li-ion battery charged to 4.2V. While the automotive power system treats the battery pack as a single high-voltage battery and charges and discharges the entire pack at a time, the battery control system must consider each battery independently. [0003] At present, during the transportation and installation of most equipment, due to the large size of the battery pack, it is easy to collide with other parts of the car, resulting in damage to the battery pack, so it needs to be improved.
