Abstract

Un método de activación de fuga térmica se relaciona con el campo técnico de las baterías. El método de activación de fuga térmica incluye: proporcionar una celda de batería (100) y un elemento de calentamiento (200) dispuestos en la celda de batería (100); y calentar el interior de la celda de batería (100) mediante el elemento de calentamiento (200), para provocar una fuga térmica de la celda de batería (100). El elemento de calentamiento (200) está dispuesto dentro de la celda de batería (100), y el elemento de calentamiento (200) calienta el interior de la celda de batería (100) para provocar la fuga térmica de la celda de batería (100), de forma que el interior de la celda de batería (100) se pueda calentar para provocar la fuga térmica de la celda de batería (100) en un tiempo relativamente corto. Debido al espacio interno reducido de la celda de batería (100), el rango de difusión del elemento de calentamiento (200) dentro de la celda de batería (100) es pequeño y la pérdida de calor del elemento de calentamiento (200) es relativamente pequeña, por lo que la introducción de una cantidad relativamente pequeña de energía externa puede activar la fuga térmica de la celda de batería (100). Este método no destruye la estructura de la celda de batería (100), garantiza la hermeticidad de la celda de batería (100) que se va a probar y puede simular el comportamiento de la celda de batería (100) más cerca de la fuga térmica real.
