Abstract

The invention provides a fully-sealed laminated battery box. The fully-sealed laminated battery box comprises a plurality of shells, sealing elements and baffles, wherein the plurality of shells are arranged sequentially; each shell has a shallow slot shape and has a geometrical shape and a mounting space matched with a storage battery in the shell; each sealing element is arranged between the adjacent shells, so that the adjacent shells are tightly connected and mutually sealed with each other; the baffles are arranged at the two ends of shell arrangement; insulating layers and the sealing elements are arranged among the baffles and the shells; terminals of a storage battery pack are arranged on the baffles and are connected with an outer circuit; and the baffles and the shell arrangement are clamped tightly through fastening elements, so that the battery box is formed. The fully-sealed laminated battery box provided by the invention has the advantages of simple types of parts, simple structure, easiness in assembly, production management and quality management, high sealing property and high protection grade reaching IP67.

Description

technical field [0001] The invention relates to a battery box for an electric vehicle, in particular to a fully enclosed laminated battery box. Background technique [0002] At present, the global supply of petrochemical energy is in short supply, and environmental protection is under great pressure. As a new type of transportation, electric vehicles are getting more and more attention from the society, and their related technologies are changing with each passing day. The battery system as one of the main systems has also been developed, such as the adoption of new batteries, integrated battery management systems, etc., but the battery box that carries the battery as one of the battery auxiliary devices has not changed significantly. Most electric vehicles install the battery directly on the car body; there is a battery box with a quick battery replacement mode, which has been used in the pure electric bus used in the Beijing Olympic Games. [0003] The battery box of the...
