  • Publication number: 20210194332
    Abstract: One embodiment provides a remotely controllable gas engine replacement device including a housing, a battery receptacle coupled to the housing, the battery receptacle configured to removably receive a battery pack, a motor located within the housing, a power take-off shaft receiving torque from the motor and protruding from a side of the housing, a power switching network configured to selectively provide power from the battery pack to the motor, and one or more remote control device interfaces configured to communicate with the remote control device. The remotely controllable gas engine replacement device also includes an electronic processor coupled to the power switching network and the remote control device interface. The electronic processor configured to control the power switching network to rotate the motor, receive a control signal from the remote control device, and execute a responsive action to the control signal from the remote control device.

  • Patent number: 9869665
    Abstract: A system including one or more generators predicts engine oil life. Generator data is received or generated by a controller. The generator data describes the operation of the generator including a load placed on the generator. Engine data may also be received or generated by the controller describing an engine coupled to the generator. The controller calculates an estimated oil life based at least on the generator data and/or the engine data.
