Problems solved by technology

[0004] Although the lithium-ion power battery has high energy and high power, it must work in an appropriate temperature range to work normally and safely. For example, if the temperature is too low, it will cause charging failure, and if the temperature is too high, it will cause the battery to explode. Seriously, it may ignite Other materials in the battery pack will eventually lead to fire and chain explosion, which will cause people's property loss and pose a threat to personal and public safety

Abstract

The invention discloses a flame retarding device and method and an electric vehicle. The flame retarding method comprises the following steps: air in a power battery pack is exhausted; and when the pressure in the power battery pack is detected to reach a preset value, flame retarding gas is injected in the power battery pack. The flame retarding method can effectively stop the combustion in the battery pack to protect the people life and property safety.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a flame retardant device and method thereof, and an electric vehicle. Background technique [0002] In recent years, with the daily consumption of oil and the continuous deterioration of the environment caused by vehicle exhaust, many countries have issued a date to ban the sale of fuel vehicles. [0003] At this time, electric vehicles, which use electricity as energy, came into being. In recent years, with the development of battery technology, lithium-ion-based power lithium batteries are very active in the market due to their light weight, high energy, and high energy density. [0004] Although the lithium-ion power battery has high energy and high power, it must work in an appropriate temperature range to work normally and safely. For example, if the temperature is too low, it will cause charging failure, and if the temperature is too high, it will cause the battery...
