6 FAQs about [A group of lithium battery packs are broken]

Does lithium-ion battery pack have a ground impact?

A hypothetic global FE model is developed for ground impact of battery pack. Parametric study is carried out for ground impact of battery pack. Failures of individual cell and shell casing are predicted with detailed models. The present paper documents a comprehensive study on the ground impact of lithium-ion battery packs in electric vehicles.

Do lithium-ion batteries need to be separated from each other?

For fire safety reasons, particularly in bulk storage areas, lithium-ion batteries should be separated from each other from hot combustion products and from oxidizers to mitigate and prevent fire spread following an initiating incident such as a single cell undergoing thermal runaway.

What causes a lithium ion battery to fail?

Overheating is one of the main causes of lithium-ion battery failures, although physical damage to the battery can also lead to problems. Excessive heat — for example from using a faulty charger and overcharging the battery, or due to a short circuit — can damage the battery cell internally and cause it to fail.

How many series elements are in a lithium ion battery pack?

For example, a lithium-ion battery pack marked as 10.8 V nominal and 7.2 Ah can be assumed to contain three series elements (3 × 3.6 V = 10.8 V).

How is a lithium-ion battery pack initiated?

The initiation method for a lithium-ion battery pack involves heating a single fully charged cell within the pack to thermal runaway using the installed heater. This method mimics a severe cell internal fault.

Are lithium-ion batteries flammable?

From a safety and fire protection standpoint, lithium-ion batteries present some new challenges due to their flammable organic electrolyte. This is a high energy density battery type, and the design of batteries containing lithium-ion cells, as well as the storage and handling of these batteries, must take this into account.
