Battery management system

The invention relates to a battery management system. When there is a code authentication request (S200: YES), the server executes a process including executing a code authentication process (S202), transmitting an authentication result (S204), when battery information is received (S206: YES), storing the battery information (S208), calculating a degradation estimation value (S210), setting degradation information (S212) corresponding to the code, and transmitting the degradation information (S214). 本公开涉及电池管理系统。服务器执行包括如下步骤的处理：当存在代码认证请求时(S200：是)，执行代码认证处理(S202)，发送认证结果(S204)，在接收到电池信息的情况下(S206：是)，存储电池信息(S208)，计算劣化推定值(S210)，设定与代码相应的劣化信息(S212)，以及发送劣化信息(S214)。
