BATTERY WITH THERMALLY COUPLED BUSSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18600279 titled 'BATTERY WITH THERMALLY COUPLED BUSSING

Simplified Explanation:

This patent application describes a battery pack with a thermal interface material (TIM) that helps regulate the temperature between two busbars while charging.

• The battery pack includes a first busbar, a second busbar, and a TIM with a thermal conductivity constant between 1.0 and 7.0 W/mK.
• The TIM establishes a thermal interface between the first and second busbars to manage heat dissipation.
• A control assembly is included to regulate the charging mode, ensuring one busbar is active while the other is inactive.

Key Features and Innovation:

• Inclusion of a TIM with specific thermal conductivity values for efficient heat management.
• Control assembly for regulating the charging mode to optimize battery performance.
• Improved thermal interface between busbars for enhanced safety and longevity of the battery pack.

Potential Applications:

• Electric vehicles
• Portable electronic devices
• Energy storage systems

Problems Solved:

Original Abstract Submitted

A battery pack includes a first busbar, a second busbar, and a thermal interface material (TIM) including a thermal conductivity constant (k) value between 1.0 and 7.0 watts per meter-kelvin (W/mK). The TIM establishes a thermal interface between the first busbar and the second busbar. The battery pack also includes a control assembly configured to regulate a charging mode of the battery pack in which the first busbar is active and receives an electrical current and the second busbar is inactive.
