**10. Conclusion**

In this study of applying RLIB in WWTP, a rough estimation by calculating the range of DoD by using EMS obtains the elongated range of an RLIB's life cycle up to 45% from 1100 to 1600 cycles at effective capacity of 80% based on the formulation in [48]. Under the consideration of environment, cost, and performance, the possibility of using automotive RLIBs is studied. One simple and converterless EMS is developed to use in a new RLIB pack. The bench test and rough estimation reveal that the EMS shows great potential in elongating life cycle and enhancing electricity charges. Furthermore, a simple, training-free, and easily implemented scheme based on ECM is applied in EMS. It is capable of online estimation of VOC and life cycle-sensitized IR for ensuring the safety of RLIB packs.

Next phase, a pilot run to install small-scale RLIB in Dihua plant is launched. For reflecting the best in-situ energy efficiency, remote power monitoring system is used to measure the peak and averaged energy consumption of aeration tank. It will function in the decision of optimized PWM signals for elongating the life cycle of RLIB.
