Description

BATTERY PACK AND VEHICLE COMPRISING THE BATTERY PACK

The present invention relates to a battery pack and an automobile including such a battery pack.

A secondary battery having high applicability according to the product group and having electrical characteristics such as high energy density, etc. is not only portable equipment but also electric vehicles (EV, Electric Vehicle) or hybrid vehicles (HEV, Hybrid Vehicle) driven by electric driving sources. It is used universally. These secondary batteries are attracting attention as a new energy source for eco-friendliness and energy efficiency enhancement, in that they do not generate any by-products due to the use of energy, as well as a primary advantage that can dramatically reduce the use of fossil fuels.

Currently widely used secondary batteries include lithium ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel hydrogen batteries, and nickel zinc batteries. The operating voltage of the unit secondary battery cell, that is, the unit battery cell is about 2.5V to 4.2V. Therefore, when a higher output voltage is required, a battery pack may be configured by connecting a plurality of battery cells in series. In addition, a battery pack may be configured by connecting a plurality of battery cells in parallel according to the charge/discharge capacity required for the battery pack. Accordingly, the number of battery cells included in the battery pack may be variously set according to a required output voltage or charge/discharge capacity.

Meanwhile, when a battery pack is configured by connecting a plurality of battery cells in series/parallel, a battery module composed of at least one battery cell is configured first, and other components are added using the at least one battery module to add a battery pack. How to configure it is common.

Conventional battery packs generally include a pack case comprising at least one battery module and at least one battery module.
