Elevator emergency power systems and methods

A method to supply emergency power to an elevator having one or more lithium batteries, an inverter coupled to the lithium batteries, a battery management system (BMS) coupled to the inverter, an Energy Management Software (EMS) coupled to the BMS, and a relay coupled to utility power, the method comprising:

• operating the relay operates to provide utility power to the system and notifying the EMS that utility power is on, wherein the EMS initiates charging of the BMS system, wherein the BMS sends charging command to the inverter, which operates until the state of charge is 100%, where the inverter goes into a standby mode
• providing emergency power during utility power outages permitting the elevator to function with a sequence of operations is for elevators with regenerative power and includes an integrated electrical and communication single line diagram and four operation profiles.
