Battery system and electric vehicle using the battery system |
摘要 |
A battery system includes a battery assembly (Bat) including a plurality of modules (Md), which is controlled by a system control circuit (SYC), each module including a module control circuit (MC) and a module by-pass circuit (R, Q) which is controlled via the module control circuit (MC) so as to suppress the charging variation among the plurality of modules (Md); wherein each control circuit (MC) and the system-controlling circuit (SYC) is connected to each other with a bilateral transmission means (SCD), and each module by-pass circuit (R, Q) is controlled based on information bilaterally transmitted between each module control circuit (MC) and the system control circuit (SYC) via the bilateral transmission means (SCD). <IMAGE> |
