What is claimed is:

1. An elevator system comprising:

at least one lithium-ion battery;

a temperature sensor operatively coupled to the at least one lithium-ion battery; and a lithium-ion battery charging system including a controller including a central processing unit (CPU) interconnected functionally via a system bus to the at least one lithium-ion battery and the temperature sensor, and at least one memory device thereupon stored a set of instructions which, when executed by the CPU, causes the lithium-ion battery charging system to:

determine an expected run mode for the elevator system;

sense a temperature of the lithium-ion battery through the temperature sensor 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.

2. The elevator system according to claim 1, wherein the set of instructions which, when executed by the CPU, causes the lithium-ion battery charging system to raise the temperature of the lithium-ion battery to a predetermined temperature level if the sensed temperature is below a desired temperature.

3. The elevator system according to claim 2, wherein the set of instructions which, when executed by the CPU, causes the lithium-ion battery charging system to activate a heater to raise the temperature of the lithium-ion battery to the desired temperature.

4. The elevator system according to claim 2, wherein the set of instructions which, when executed by the CPU, causes the lithium-ion battery charging system to establish a charging profile to raise the temperature of the lithium-ion battery to the desired temperature.

5. The elevator system according to claim 1, wherein determining the expected run mode for the elevator system includes identifying one of an up-peak operating mode, a down-peak operating mode, and an off-peak operating mode.

6. A method of charging a lithium-ion battery for an elevator system comprising: determining an expected run mode for the elevator system;

sensing a temperature of the lithium-ion battery through the temperature sensor establishing a sensed temperature; and

establishing a state of charge (SOC) for the lithium-ion battery based on the sensed temperature and expected run mode of the elevator system.

7. The method of claim 6, further comprising: raising the temperature of the lithium-ion battery to a predetermined temperature level if the sensed temperature is below a desired temperature.

8. The method of claim 7, wherein raising the temperature includes activating a heater operatively connected to the lithium-ion battery.

9. The method of claim 7, wherein raising the temperature includes establishing a charging profile for the lithium-ion battery.

10. The method of claim 6, wherein determining the expected run mode for the elevator system includes identifying one of an up-peak operating mode, a down-peak operating mode, and an off-peak operating mode.

11. A battery operated elevator system comprising:

an elevator car;

a motor drive system operatively connected to the elevator car;

a lithium-ion battery operatively coupled to the motor drive system;

a temperature sensor operatively coupled to the lithium-ion battery; and

a controller operatively connected to the lithium-ion battery, the controller establishing a state of charge (SOC) for the lithium-ion battery based on a temperature sensed by the temperature sensor and an expected run mode of the elevator system.

12. The battery operated elevator system according to claim 11, further comprising: a heater operatively coupled to the controller and the lithium-ion battery for selectively raising a temperature of the lithium-ion battery.
