Abstract
A battery pack has a battery connection assembly for connecting to an electric motor with at least one lithium-based rechargeable cell therein and associated means for turning the at least one lithium-based rechargeable cell ON or OFF. The battery pack is configured to store a reserve within the at least one lithium-based rechargeable cell that is sufficient to start the engine electric motor. The battery pack can be activated by the associated means for turning the at least one lithium-based rechargeable cell ON or OFF to access the reserve to start the engine electric motor.
Claims19
A system for starting an engine electric motor, the system comprising:
- a battery pack housing,
- a battery pack having a battery connection assembly for connecting to the electric motor with at least one lithium-based rechargeable cell therein and associated means for turning the at least one lithium-based rechargeable cell ON or OFF,
- wherein the battery connection assembly includes means for turning the at least one lithium-based rechargeable cell OFF when the cell voltage drops to a preselected level to leave the battery pack with sufficient reserve capacity to start the engine electric motor,
- wherein the battery pack can be activated by the associated means for turning the at least one lithium-based rechargeable cell ON or OFF to start the engine electric motor, and
- wherein the battery pack, with the battery connection assembly and the at least one lithium-based rechargeable cell, and the associated means for turning the at least one lithium-based rechargeable cell ON or OFF are positioned within the battery pack housing.
A method for starting an engine electric motor, the system comprising:
- providing a battery pack housing having a battery pack with at least one lithium-based rechargeable cell therein and associated means for turning the at least one lithium-based rechargeable cell ON or OFF,
- turning the battery pack OFF when the cell voltage drops to a preselected level to leave the battery pack with sufficient reserve capacity to start the engine electric motor,
- connecting the battery pack to the engine electric motor, and
- activating the battery pack with the associated means for turning the at least one lithium-based rechargeable cell ON or OFF, so that the battery pack can start the engine electric motor and supply power thereto.
