Abstract: Systems and methods of optimizing electric motor shut off timing are disclosed. A system comprises a machine including an electric motor, at least one hardware processor, and at least one non-transitory memory. The electric motor is configured to automatically shut off after a first period of time. The at least one non-transitory memory stores instructions which, when executed by the at least one hardware processor, cause the system to determine a pattern of values based on one or more parameters of the machine and/or one or more parameters of the electric motor, generate a second period of time based on the pattern of values, and automatically shut off the electric motor based on the second period of time. In some embodiments, the pattern of values is based on one or more parameters of a user profile associated with an operator of the machine.

Abstract: In some implementations, a controller of a hybrid powertrain system may detect a level of demand associated with the load of the hybrid powertrain system. The controller may cause power to be proportionally provided to drive the load via the engine and the electric machine in accordance with a ratio between a first power output provided via the engine and a second power output provided via the electric machine, the ratio being associated with the level of the demand, a control mode associated with the hybrid powertrain system, and an operating mode associated with the hybrid powertrain system.

Abstract: A control system may include a control of a user interface and a controller. The controller may be configured to cause a machine to operate in a first mode, the machine being configured for hybrid operation in the first mode using a battery without using an internal combustion engine or in a second mode using the internal combustion engine when a level of the battery is below a threshold. The controller may be configured to receive an input, via the control, indicating that the second mode of the machine is to be disabled. The controller may be configured to cause, based on the input and when the level of the battery is below the threshold, suppression of operation of the machine in the second mode.

Abstract: In some implementations, a controller for a hybrid powertrain system may cause disengagement of an engine from an electric machine via a clutch based on a state of charge (SOC) of one or more batteries connected to the electric machine at least meeting an SOC threshold. Disengagement of the engine may cause the hybrid powertrain system to operate in an electric-only mode for powering a load. The controller may detect a power event that includes at least one of a level of demand of the load exceeding a demand threshold, or the SOC of the one or more batteries being below the SOC threshold. The controller may cause, based on detection of the power event, engagement of the engine with the electric machine via the clutch. Engagement of the engine may enable the hybrid powertrain system to operate in a hybrid mode for powering the load.
