Abstract

In order to achieve the purpose, the invention provides a battery pack and a vehicle. The vehicle comprises a vehicle body and a battery pack arranged on the vehicle body. The battery pack comprises abattery module and a box body. The box body is provided with a containing cavity, and the battery module is located in the containing cavity. The battery module comprises a plurality of battery unitsarranged in the horizontal direction, and each battery unit at least comprises one battery cell. The size of the battery module in the horizontal direction is larger than that of the battery module in the vertical direction. The size of the battery module in the vertical direction is L1, the size of the battery pack in the vertical direction is L2, and L1 / L2 is greater than or equal to 70% and less than or equal to 95%.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery pack and a vehicle. Background technique [0002] Secondary batteries have the advantages of high energy density, long service life, energy saving and environmental protection, and are widely used in different fields such as new energy vehicles and energy storage power stations. The battery pack is usually used as the power source of the car, and the battery pack includes a box body and a plurality of batteries housed in the box body. However, the temperature of the box is easily affected by the external temperature, and correspondingly, the temperature of the battery is also affected by the temperature of the box. In the known technology, the temperature of the battery is greatly affected by the temperature of the casing, which leads to unstable control of the battery temperature and affects the performance of the battery. Contents of the invention [0003] In view of the ...
