The i3 is a revolutionary model without a doubt. The technology it uses and the manufacturing process make it the most eco-friendly car out there, at the moment.
One of the key elements of the whole i sub-brand from BMW are the batteries and their advantages in front of the competition. You see, a big problem for EVs is keeping the energy within workable parameters at all times.
Unfortunately, storing this energy poses a couple of problems, especially in extreme weather, like the US recently witnessed. To make sure their i3 customers won’t experience problems with their cars, BMW decided to build a complete shell for the batteries their car will be using, to keep them as isolated from the exterior as possible.
Below, you have two videos that explain how the batteries are made and then introduced in their special aluminum container for optimum usage.
Cells are provided in cartons and then placed for testing and cleaning, having their surface cleaned with plasma before bonding. Then, the bonding agent is applied to the cells whilst employees prepare aluminum pressure plates and isolation jackets.
Joining and bonding the separate components into a module (12 cells in a module) is done using diverse shots. A robot then places the ready for use module in position followed by the cell contacting system that is placed onto the module by an employee. Laser welding follows completing the process.
