How A Battery For Electric Vehicles Is Made

A lithium-ion battery pack is made by connecting several individual lithium ion battery cells.

The cells are then assembled in a grid and connected to nickel holders.

Temperature sensors are taped to the battery pack and later attached to the Battery Management System (BMS).

After the pack is wrapped in yellow epoxy, the BMS is soldered and attached.

Lastly, the pack is inserted in a metal bracket and closed.

The last chapter involves testing of each battery pack. Read the full story on
