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.

First claim

We claim:

1. A remotely controllable gas engine replacement device comprising:
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;
one or more remote control device interfaces configured to communicate with a remote control device; and
an electronic processor connected 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,
execute a responsive action to the control signal from the remote control device,
transmit battery pack information to the remote control device via the one or more remote control device interfaces for indicating in one or more user interfaces of the remote control device, and
transmit an operating state of the gas engine replacement device to the remote control device via the one or more remote control device interfaces for indicating in the one or more user interfaces of the remote control device.

2. The remotely controllable gas engine replacement device of claim 1 , further comprising:
an electrical interface supported on the housing for providing charge from the battery pack to a battery of the remote control device.

3. The remotely controllable gas engine replacement device of claim 1 , further comprising:
a wireless receiver,
wherein the one or more remote control device interfaces configured to communicate with the remote control device includes a wireless interface, and the control signal received by the electronic processor from the remote control device is received via the wireless interface and the wireless receiver.

4. The remotely controllable gas engine replacement device of claim 1 , wherein the one or more remote control device interfaces configured to communicate with the remote control device includes a wire line interface configured to receive a cable connected to the remote control device,
wherein the control signal received by the electronic processor from the remote control device is received via the wire line interface and the cable connected to the remote control device.

5. The remotely controllable gas engine replacement device of claim 1 , wherein the battery pack information includes at least one of a level of charge of the battery pack and time remaining for use of the battery pack.

6. The remotely controllable gas engine replacement device of claim 1 , wherein the electronic processor is further configured to transmit to the remote control device one or both of:
an identity of a specified power equipment attached to and driven by the gas engine replacement device for configuring the remote control device for use with the specified power equipment, and
parameters for configuring the remote control device for use with the specified power equipment.

7. A method for remotely controlling a gas engine replacement device, the method comprising:
controlling, by an electronic processor, a power switching network to rotate a motor, the power switching network configured to selectively provide power from a battery pack to the motor, the battery pack removably received by a battery receptacle coupled to a housing of the gas engine replacement device, the motor providing torque to a power take-off shaft protruding from a side of the housing;
receiving, by the electronic processor, a control signal from the remote control device;
executing, by the electronic processor, a responsive action to the control signal from the remote control device to control the gas engine replacement device;
transmitting battery pack information to the remote control device for indicating in one or more user interfaces of the remote control device; and
transmitting an operating state of the gas engine replacement device to the remote control device via the one or more remote control device interfaces for indicating in the one or more user interfaces of the remote control device.

8. The method of claim 7 , further comprising providing, using an electrical interface supported on the housing, charging power from the battery pack to a battery of the remote control device.

9. The method of claim 7 , wherein the control signal from the remote control device is received over a wireless interface between the gas engine replacement device and the remote control device.

10. The method of claim 7 , wherein the control signal from the remote control device is received over a wire line interface between the gas engine replacement device and the remote control device.

11. The method of claim 7 , further comprising receiving a command for controlling a light of the gas engine replacement device.

12. The method of claim 7 , wherein the battery information includes at least one of a level of charge of the battery pack, and a time remaining for use of the battery pack, and wherein the operating state includes at least one of a work cycle applied to the motor, a speed of the power take-off shaft, torque applied to the motor, and an efficiency of the motor.

13. The method of claim 7 , further comprising transmitting to the remote control device one or both of
transmitting an identity of a specified power equipment attached to and driven by the gas engine replacement device to the remote control device for configuring the remote control device for use with the specified power equipment, and
parameters for configuring the remote control device for use with the specified power equipment.

14. A remote control device for controlling a gas engine replacement device, the gas engine replacement device including a power switching network to selectively provide power from a battery pack to a motor to rotate the motor and provide torque to a power take-off shaft, the remote control device comprising:
a housing;
one or more communication interfaces configured to communicate with the gas engine replacement device;
one or more user interfaces; and
an electronic processor coupled to the one or more communication interfaces and the one or more user interfaces, the electronic processor configured to:
receive input via the one or more user interfaces,
transmit a control signal to the gas engine replacement device via the one or more communication interfaces for execution of a responsive action to the control signal by the gas engine replacement device based on the received input,
transmit battery pack information to the remote control device via the one or more remote control device interfaces for indicating in one or more user interfaces of the remote control device, and
transmit an operating state of the gas engine replacement device to the remote control device via the one or more remote control device interfaces for indicating in the one or more user interfaces of the remote control device.

15. The remote control device of claim 14 , wherein the gas engine replacement device further includes:
a device housing;
