请参阅图1,在本申请的一实施例中,电池100包括电芯10和保护板组件20。所述电芯10包括电芯主体11、第一电连接组件12和第二电连接组件13。所述第一电连接组件12和所述第二电连接组件13连接所述电芯主体11和所述保护板组件20。所述保护板组件20包括第一保护电路板21和第二保护电路板22。所述第一电连接组件12包括极性相反的第一极耳121和第二极耳122,所述第二电连接组件13包括极性相反的第三极耳131和第四极耳132。所述第一保护电路板21连接所述第一极耳121和所述第二极耳122,所述第二保护电路板22连接所述第三极耳131和所述第四极耳132,从而使所述第一保护电路板21和所述第二保护电路板22均具有独立的正负极,能够为电池100提供两条充放电回路,在不降低总功率的情况下,降低流经每个保护电路板和每个极耳的电流。Referring to FIG. 1 , in an embodiment of the present application, abattery 100 includes abattery cell 10 and aprotection plate assembly 20 .
