The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

An elevator system includes at least one lithium-ion battery, a temperature sensor (56, 57) operatively coupled to the at least one lithium-ion battery (44), and a lithium-ion battery charging system (50) including a controller (30) having a central processing unit (CPU) (36) interconnected functionally via a system bus to the at least one lithium-ion battery (44) and the temperature sensor (56, 57). The controller (30) further includes at least one memory (38) device thereupon stored a set of instructions which, when executed by the CPU, causes the lithium-ion battery charging system (50) to determine an expected run mode for the elevator system, sense a temperature of the lithium-ion battery (44) through the temperature sensor (56, 57) establishing a sensed temperature, and establish a state of charge (SOC) for the lithium-ion battery based on the sensed temperature and expected run mode of the elevator system.


6. Drawings
a.
The figure of the drawings to be published with the abstract is Figure No.     1    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
