Description
Technical Field
The utility model relates to a battery technology field especially relates to a safe structure of arranging of electric motor car lithium cell group.
Background
At present, most batteries of electric vehicles on the market are externally arranged outside the whole vehicle, the structural arrangement mode of the electric core inside the battery pack is basically a traditional arrangement structure of a lying test, the electric core is close to an electric core fixing structure, no gap exists between the electric core and the electric core, and no good flame-retardant technical scheme exists, so that the danger of burning, firing and even explosion caused by local overheating of the battery pack in the driving process can be caused, and serious potential safety hazards are caused; in addition, the battery cell is assembled into a battery pack with small shape and size and low plasticity; the traditional battery core arrangement assembly mode is complex in processing and high in material consumption and cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is to have the unsafe problem of arranging of battery among the background art, provides a safe structure of arranging of electric motor car lithium cell group.
The technical scheme of the utility model: a safe arrangement structure of a lithium battery pack of an electric vehicle comprises an outer packaging material, a battery cell, a fireproof heat dissipation material, a connecting nickel sheet, a fireproof sponge and a charging and discharging wire;
be equipped with on the external packing material and supply electric core male electric hole, the external packing material front end sets up the fire prevention sponge, sets up fire prevention heat dissipation material between the adjacent electric core and interconnects through connecting the nickel piece.
Preferably, the cells are arranged in a plurality of rows.
Preferably, the multiple rows of cells are arranged in a ladder manner.
Preferably, the outer package material is provided with a charge and discharge wire at the tip.
Preferably, a protection plate is provided at the rear end of the outer package.
Compared with the prior art, the utility model discloses following profitable technological effect has: the battery cells are vertically arranged, and a certain distance is reserved between every two battery cells, so that the defects that the current battery pack of the electric vehicle is unreasonable in structure, small in assembled appearance size and not strong in plastic appearance are overcome; fireproof heat dissipation materials can be arranged in the cell spacing, so that the excessive heating generated by a lithium battery pack in the use or charging process of the electric vehicle can be reduced or even avoided, and the appearance can be more changeable to meet the requirements of different scene sizes; the problems of insufficient heat dissipation, fireproof and flame retardant processes and the like in the traditional battery pack assembly process are solved, so that the battery of the electric vehicle is safer and more efficient to use; simplify group battery manufacturing procedure, reduce group battery processing cost.
