BATTERY MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18463052 titled 'BATTERY MODULE
Simplified Explanation
The abstract describes a battery module that includes a battery stack, end plates, a restraint member, and a welded portion.
- The battery module consists of a stack of multiple batteries.
- The end plates are located at both ends of the battery stack and are made of two different metals.
- One end plate has a first portion made of a metal with a higher Young's modulus and a second portion made of a metal with a lower density.
- The restraint member, made of the metal with the higher Young's modulus, holds the battery stack and end plates together.
- The welded portion connects the first portion of the end plate with the restraint member.
Potential applications of this technology:
- Electric vehicles
- Renewable energy storage systems
- Portable electronic devices
Problems solved by this technology:
- Provides structural stability to the battery module
- Reduces the weight of the end plates without compromising strength
Benefits of this technology:
- Improved performance and durability of battery modules
- Increased energy efficiency
- Cost-effective manufacturing process
Original Abstract Submitted
A battery module includes: a battery stack that includes a plurality of batteries stacked; a pair of end plates that are disposed at both ends, in stack direction X in which the batteries are stacked, of the battery stack, the pair of end plates including at least one end plate that includes a first portion made of a first metal that has a Young's modulus higher than a Young's modulus of a second metal, and a second portion made of the second metal that has a density lower than a density of the first metal; a restraint member that is made of the first metal and sandwiches the battery stack and the pair of end plates in stack direction X; and a welded portion that connects the first portion of the at least one end plate with the restraint member.
