Electric vehicle (EV) batteries are complex systems that require careful design and manufacturing to ensure safety and performance. One critical component of EV batteries is the compression pad, which is used to prevent thermal runaways and protect battery cells from damage. In this article, we discuss the different types of compression pads used in EV battery cells.
There are several types of compression pads, including solid-state, spring-loaded, and gel-based compression pads. Solid-state compression pads are made of a rigid material and provide a stable platform for the battery cells. Spring-loaded compression pads use a spring mechanism to apply a constant force on the battery cells, which helps to accommodate cell breathing and swelling. Gel-based compression pads are made of a soft, flexible material that can conform to the shape of the battery cells and provide excellent shock absorption.
Each type of compression pad has its advantages and disadvantages, and the choice of compression pad depends on the specific requirements of the EV battery system. For example, solid-state compression pads are more durable and less prone to wear and tear, while spring-loaded compression pads are more flexible and can accommodate changes in the battery cell dimensions.
In conclusion, the choice of a compression pad is an essential factor in designing and manufacturing EV batteries that are safe and perform well. By understanding the different types of compression pads available, EV designers and manufacturers can make informed decisions about the best compression pad for their specific needs.
