No entanto, o aumento da temperatura durante o processo de descarga afeta seriamente a seguran\u00e7a operacional e a vida \u00fatil da bateria, podendo at\u00e9 mesmo causar acidentes. Portanto, \u00e9 necess\u00e1rio estudar a influ\u00eancia da temperatura de opera\u00e7\u00e3o das baterias de l\u00edtio na seguran\u00e7a.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. Durante um \u00fanico ciclo de carga e descarga de uma bateria de l\u00edtio, quando a taxa de carga permanece constante, \u00e0 medida que a taxa de descarga aumenta, a temperatura m\u00e1xima da bateria tamb\u00e9m aumenta. As medidas de dissipa\u00e7\u00e3o de calor precisam controlar a temperatura para que ela n\u00e3o ultrapasse a temperatura m\u00e1xima ideal de opera\u00e7\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. Sob descarga de corrente constante com diferentes correntes, a pot\u00eancia de gera\u00e7\u00e3o de calor da bateria de l\u00edtio n\u00e3o \u00e9 a mesma, e sua temperatura m\u00e1xima tamb\u00e9m varia. Do centro da bateria de l\u00edtio para os quatro cantos, a temperatura diminui gradualmente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. Em temperatura ambiente de 25 \u00b0C, taxa de carga de 0,5 C e dissipa\u00e7\u00e3o de calor natural, quando a bateria de l\u00edtio realiza um \u00fanico ciclo de carga e descarga, a taxa de descarga dentro da faixa de temperatura operacional ideal n\u00e3o deve exceder 1,50 C. Quando a taxa de descarga da bateria de l\u00edtio exceder 2,74 C, a temperatura m\u00e1xima da bateria para completar um \u00fanico ciclo de carga e descarga ultrapassar\u00e1 o limite de seguran\u00e7a. Portanto, para prolongar a vida \u00fatil das baterias de l\u00edtio, a taxa de descarga precisa ser controlada dentro de uma faixa razo\u00e1vel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. Al\u00e9m da taxa de descarga da bateria de l\u00edtio, a temperatura ambiente externa tamb\u00e9m \u00e9 um dos fatores significativos que afetam o ambiente t\u00e9rmico interno durante ciclos cont\u00ednuos de carga e descarga. Para manter a temperatura da bateria de l\u00edtio dentro da faixa ideal de opera\u00e7\u00e3o, \u00e9 necess\u00e1rio reduzir continuamente a temperatura externa por meio de ventila\u00e7\u00e3o e dissipa\u00e7\u00e3o de calor quando a taxa de descarga da bateria de l\u00edtio aumenta uniformemente. Assim, a bateria de l\u00edtio pode continuar funcionando.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/greenbattpower.com\/wp-content\/uploads\/2022\/04\/%E4%BB%BF%E7%9C%9F%E5%88%86%E6%9E%90-1024x445.jpg\" alt=\"energy storage battery\" class=\"wp-image-910\"\/><\/figure>","protected":false},"excerpt":{"rendered":"<p>As the core component of the\u00a0energy storage system, the safe operation of the lithium battery is extremely important.
