Li Ion Battery Pack Schematic Diagram

A lithium-ion battery pack is a collection of lithium-ion cells connected in series and/or parallel to provide a desired voltage and capacity. The schematic diagram of a lithium-ion battery pack shows the components of the pack and how they are connected.

Components of a Lithium-Ion Battery Pack

The following are the main components of a lithium-ion battery pack: *

Cells:

The cells are the basic unit of a lithium-ion battery pack. They consist of a positive electrode, a negative electrode, and an electrolyte. *

BMS (Battery Management System):

The BMS is responsible for managing the battery pack. It monitors the voltage, current, and temperature of the cells, and it prevents the battery from being overcharged or discharged. *

Connector:

The connector allows the battery pack to be connected to a device. *

Safety Features:

Lithium-ion batteries are flammable, so they must have safety features to prevent them from catching fire. These features may include a fire-resistant housing, a thermal fuse, and a venting mechanism.
