The lithium battery pack will be powered off when it is powered on

What if a portable electronic device is powered by lithium batteries?

When portable electronic devices powered by lithium batteries are in checked baggage, they must be completely powered off and protected to prevent unintentional activation or damage. In electronic devices capable of generating extreme heat the heating elements must be mitigated by removal of the heating element, battery, or other components.

What is a lithium ion battery pack?

Lithium-ion battery packs are widely used in consumer electronics due to their high energy density and low self-discharge rate. They consist of lithium-ion cells which can hold a significant amount of energy relative to their size and weight.

How does a battery pack work?

When a device is connected, the stored energy is converted back into electrical power. Voltage Regulation: Portable devices require a specific voltage to operate. Battery packs include voltage regulators that adjust the electrical output to match the device’s requirements. This ensures optimal performance and prevents damage to the device.

What should I do if my lithium battery is overheating?

Passengers should notify flight crew immediately if their lithium battery or device is overheating, expanding, smoking or burning. When portable electronic devices powered by lithium batteries are in checked baggage, they must be completely powered off and protected to prevent unintentional activation or damage.

How does a battery pack discharge?

Discharge Process: When a battery pack powers a device, a chemical reaction occurs within the cells. This reaction releases electrons, which flow through the circuit to provide power. The rate of discharge can vary based on the battery chemistry and the power demands of the connected device.

What are the advantages and disadvantages of lithium-ion battery packs?

Lithium-ion battery packs have several advantages and disadvantages. Their benefits include high energy density and low self-discharge rates. However, they also face concerns such as thermal runaway and resource scarcity.
