Abstract

The invention relates to a power battery cell arrangement method of an electric vehicle, and a battery pack. In the battery pack of the electric vehicle, power battery cells are obliquely fixed in a battery pack shell instead of the bottom surface of the battery pack shell and / or the side surface of the battery pack shell. According to the battery pack, as the power battery cells are obliquely fixed in the battery pack shell, damage to the power battery cells in a bottom-supporting accident can be reduced under the condition of not increasing the cost and the mass of the whole vehicle, and the safety and the reliability of the battery pack in the bottom-supporting accident are improved.

Description

technical field [0001] The invention relates to the technical field of power batteries of electric vehicles, in particular to a method for arranging power battery cells of electric vehicles and a battery pack. Background technique [0002] Electric-vehicle battery (EVB) is used in pure electric vehicles (BEV) or hybrid electric vehicles (HEV) to supply motor energy. At present, the electric vehicle batteries of electric vehicles mainly use lithium-ion batteries, and are generally placed at the bottom of the electric vehicle, that is, mainly integrated on the bottom plate of the vehicle body. Among them, in order to meet the needs of electric vehicles with a greater driving range, the volume of the battery pack is usually increased to accommodate more power battery cells, so that more energy can be continuously provided to the motor, but in this case In order not to reduce the space inside the car and increase the overall height of the vehicle, the height of the floor will b...
