        應用案例 Application Case : FZ16C-EV324

        該項目是為某乘用車型定制開發的高能量電池系統。系統使用了標準本征安全模塊,可以確保失效的單顆電芯被有效隔離,保障系統安全;高能量密度電芯加輕量化設計保證系統能量密度在120Wh/Kg以上;溫度場和電流密度分布的均勻性設計保障電芯的工作條件一致,故模塊循環壽命與電芯相比無明顯衰減;由于電芯的內阻很低,可低溫放電且發熱量很小,該系統不需任何輔助溫度控制裝置即可在北方的冬季和南方的夏季正常工作。

        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.
