运用案例 Application Case : FZ16C-EV324

该项目是为某乘用车型定制开辟的高能量电池体系。体系运用了尺度本征平安模块,能够确保生效的单颗电芯被有用断绝,保障系统安全;高能量密度电芯加轻量化设想包管体系能量密度正在120Wh/Kg以上;温度场和电流密度散布的匀称性设想保障电芯的事情前提同等,故模块轮回寿命取电芯比拟无显着衰减;因为电芯的内阻很低,可高温放电且发热量很小,该体系不需任何辅佐温度掌握装配便可正在北方的夏季和南边的夏日一般事情。

The EV battery system is customized for passenger EV. Intrinsic safe module is adopted to ensure system safety by effective thermal run-away cell insulation. The system energy density is more than 120Wh/Kg due to high energy density cell and light-weighting design. The uniformity design of thermal field and current density distribution guarantees that all the cells work under same condition, so that there is no deterioration of system life compared with single cell. The cell could discharge under low temperature and generate less heat due to low IR, so the system can operate normally in northern winter and southern summer without any additional temperature-adjusting devices.
