How does a battery tray assembly work?

Battery tray assembly includes many process stages, including tightening, applying the sealing application, joining the cooling system, and riveting the compartments. All steps must be completed while ensuring the level of quality of each step.

How do I engineer a battery pack?

In order to engineer a battery pack it is important to understand the fundamental building blocks, including the battery cell manufacturing process. This will allow you to understand some of the limitations of the cells and differences between batches of cells. Or at least understand where these may arise.

How does a cell assembly process work?

The cell assembly process begins with finished electrode reels. In pouch and prismatic cells with stacked electrodes, anodes and cathodes are separated from the electrode daughter rolls and cut to size, leaving the current collector as a tab. Details:

Can battery cells be stacked into modules?

Stacking battery cells into modules is a short-cycle precise process with the utmost quality demands. Defects are not accepted, and there are no second chances to get it right. The battery cells need to be firmly attached, and the joint must meet the highest requirements in terms of rigidity and crash behavior.

What is an electric vehicle battery tray?

The electric vehicle (EV) battery tray consists of several assembled battery modules. The battery tray ensures that the battery can provide optimal performance and is also an essential part of providing structural stability to the vehicle.

Do EV batteries need air pockets?

In the case of a crash, air pockets can lead to short circuits, a major safety issue in high-voltage EV power systems. As if these requirements do not represent a challenge, the joint also needs to be elastic, providing a tolerance for the cells to expand slightly when charging and discharging. And finally, the form of the battery cells can vary.
