Each battery pack is configured to be removed and used separately or added to a combination of battery packs. A control unit selectively opens and closes switching elements to separately control the connections between the battery packs and an electrical load, such as a motor. During charging, the control unit opens and closes switching elements to control the charging rate of the individual battery packs. When the battery packs are connected to an electrical load, the control unit controls the state of the switching elements to selectively discharge the battery packs to power the riding vehicle and/or electric loads.

A transportation vehicle including a plurality of battery packs, a plurality of power equipment, and a controller. The controller is configured to identify at least one of the plurality of power equipment or at least one of the plurality of battery packs that requires charging and direct power through a bus to distribute power to at least one of the plurality of power equipment or at least one of the plurality of battery packs. The plurality of battery packs are configured to recharge the plurality of power equipment.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs jointly provide power to the riding lawn mower.

An operating system for a standby generator includes a control unit, a switch, an inverter, a terminal, a current sensor, a starter circuit, a power control circuit, and an ignition kill circuit. The control unit is powered by a rechargeable twelve volt DC battery. The switch is selectively operable by the control unit to connect one of a first input or a second input to an output. The second input receives the supply of electrical power from an internal combustion engine. The inverter is positioned between the DC battery and the first input, and supplies electrical power to the electrical device when a movable contact of the switch connects the output to the first input. The power control circuit is connected to the control unit and is operable to adjust the movable contact of the switch to selectively connect the output to either the first input or the second input.

On-demand generator starting system

A zero turn radius mower including a pair of rear drive wheels, a mowing deck including multiple cutting blades, an electric storage battery, a pair of electric wheel motors each operable to rotate one of the rear drive wheels, multiple electric blade motors each operable to rotate one of the multiple cutting blades, and a master controller in communication with each of the pair of wheel motors and the multiple blade motors. The master controller is operable to control a rotational speed of each of the pair of wheel motors and the multiple blade motors. The master controller is operable to stop rotation of the cutting blades when the wheel motors are operating below a threshold speed.

Portable jobsite equipment includes a generator including an internal combustion engine and an alternator. The internal combustion engine includes a first cylinder including a first spark plug configured to create a first electrical spark, a second cylinder including a second spark plug configured to create a second electrical spark, an electronic control unit configured to activate and deactivate at least one of the first cylinder and the second cylinder, and a load source receiving supplied power from the generator. The electronic control unit activates one of the first cylinder and the second cylinder in response to a threshold increase of the load source.

Cylinder deactivation for a multiple cylinder engine

A battery pack includes a housing, rechargeable lithium-ion battery cells enclosed in the housing, terminals, a processing circuit, and a communications interface. The processing circuit is configured to control a supply of electrical power from the rechargeable lithium-ion battery cells to a positive terminal and a negative terminal in response to receiving signals from data terminals. The signals from the data terminals include operational information that includes at least a condition of an electric motor on power equipment coupled with the data terminals.

The processing circuit is configured to adjust one or more functions of the battery pack based upon identification data received from the communications interface, which includes the type of power equipment that is coupled with the plurality of terminals.

An electric starting system for an internal combustion engine is provided. The starting system includes a battery, a starter motor, and a blower housing. The starter motor is configured to start the internal combustion engine. The battery is integrated with the blower housing.

Electric starting system for an internal combustion engine

A starter motor connected to a power supply and operable to start an internal combustion engine includes an outer housing and a solid state switching device associated with the outer housing. The outer housing encloses a commutator and a series of brushes. The solid state switching device is movable between an open position and a closed position. The current flow from the power supply through the commutator is prevented when the solid state switching device is in the open position.

Starter motor with integrated solid state switch

An on-demand generator starting system and method is disclosed. The generator starting system is included as part of a standby or portable generator that includes one or more outlets that provide electrical power to an electrical device. The operating system includes a generator controller that monitors for a request for power from the electrical device connected to the outlet. When the control circuit of the generator controller determines that electric power is required from the generator, the control circuit initiates operation of the internal combustion engine. After the internal combustion engine starts, the control circuit operates a relay to provide power from the generator to the outlet of the generator. When the electrical device is no longer operating, the control circuit of the generator controller terminates operation of the internal combustion engine of the generator. In this manner, the generator operates only when the electrical device is requesting electrical power.
