Abstract

The invention relates to a bottom shell of a power lithium battery module. The bottom shell comprises a bottom plate and a cover plate, wherein the cover plate is attached onto the bottom plate, lifting jacks are formed in edges of the bottom plate and the cover plate, a sealing convex edge is welded at an inner side of each lifting jack, a plurality of groups of lithium battery placement groovesare formed in an inner side of the sealing convex edge, collision-prevention connection pieces are connected to tail parts of the lithium battery placement grooves, a coil groove is reserved in a center of each lithium battery placement groove, the coil groove communicates with a coil collection groove formed in a left side of the bottom plate, and the coil groove communicates with a fixed plate arranged at a right side of the bottom plate. With the adoption of a separated arrangement structure, the placement quantity of lithium batteries is effectively increased; meanwhile, the battery shellcan be rapidly and accurately sealed by limitation holes which are vertically aligned; and a worker is more convenient to arrange a coil by a simple circuit passage in the bottom shell.

Description

technical field [0001] The invention relates to automobile carrier processing equipment, in particular to a power lithium battery module bottom case. Background technique [0002] Energy saving and environmental protection are one of the main directions of automobile development. Electric vehicles have been paid more and more attention to as an effective means of reducing pollution and emissions. Lithium batteries have high voltage platform, high specific energy, low self-discharge, and cycle performance. Good and other advantages become the dominant power source of electric vehicles. [0003] At present, the new energy vehicle technology is becoming more and more mature, and the hybrid electric vehicle technology is also becoming more and more perfect. Among them, the power battery is the main energy carrier and power source of various electric vehicles, and is also the main component of electric vehicles. However, most lithium battery vehicles have immature battery bottom...
