Embodiment Construction

[0086] refer to Figure 1-7 , the battery pack 1 is configured to provide power to the vehicle powertrain and thus can operate at a relatively high voltage. As used herein, the term high voltage refers to voltages greater than 100V. For example, in some embodiments, battery pack 1 may operate at 400V, while in other embodiments, battery pack 1 may operate at 800V. The battery pack 1 includes a battery pack case 2 for accommodating battery modules 40 , and each battery module 40 includes an electrochemical cell 200 . The battery pack housing 2 includes a container 4 and a lid 6 closing the open end of the container 4 and connected to the open end of the container via a fluid impermeable seal 8 . The battery pack case 2 has a flat shape. As used herein, the term "prolate shape" means having a small height hp relative to the length lp and width wp. In the battery pack housing 2 , the height hp corresponds to the distance between the lid 6 and the bottom of the container 4 . ...

Abstract

A battery pack includes a battery pack housing sealed and filled with a dielectric fluid. Further, the battery pack includes a battery module disposed in the battery pack case and a vent block disposed on the cover and communicating with an internal space of the battery pack case. The vent block is configured to allow the battery pack to accommodate a volume change of the dielectric fluid within the battery pack housing.

Description

technical field [0001] Battery packs power everything from portable electronics to renewable energy systems and environmentally friendly vehicles. For example, hybrid electric vehicles use a battery pack and electric motor in conjunction with an internal combustion engine to improve fuel efficiency. A battery pack may be formed from a plurality of battery modules, where each battery module includes a plurality of electrochemical cells. Within the battery module, the batteries may be electrically connected in series or in parallel. Likewise, the battery modules may be electrically connected in series or in parallel within the battery pack. Background technique [0002] In order to meet the space requirements of various applications and installation environments, different battery types have emerged, the most common types in vehicles are cylindrical batteries, prismatic batteries and pouch batteries. For example, cylindrical batteries are widely used because of their ease o...
