摘要： An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.

摘要： A starter battery system for an air cooled engine rated at less than 50 horsepower. The system includes four lithium iron phosphate cells and a charging circuit configured to be powered by rotation of an air cooled engine. A voltage developed by the charging circuit is applied to the four lithium iron phosphate cells without battery management circuitry provided between the charging circuitry and the four lithium iron phosphate cells.
An engine which includes at least one piston, a rotatable crankshaft coupled to the at least one piston, a starter motor configured to selectively initiate rotation of the crankshaft, a lithium-ion battery in electrical communication with the starter motor, the lithium-ion battery having at least one cell, and a charging system configured to be powered by motion of at least one component of the engine. The charging system is configured to continuously apply a voltage potential to the at least one cell while the engine is in a running condition.

摘要： A lawn mower includes a chassis, a cutting deck, a chore motor, and a blade. The chassis supports several wheels. The cutting deck is supported by the chassis and defines a cutting chamber. The chore motor is electrically coupled to the battery. The chore motor includes a housing containing a coil assembly, a rotor, and a drive shaft extending out of the housing. The chore motor is attached to the cutting deck so that at least a portion of the housing and the drive shaft are positioned within the cutting chamber. The blade is coupled to the drive shaft and is configured to rotate within the cutting chamber when the chore motor rotates the rotor and drive shaft.

摘要： A lawn mower includes a chassis supporting a wheel, a cutting deck supported by the chassis and defining a cutting chamber, a battery supported by the chassis, and a chore motor electrically coupled to the battery. The chore motor includes a housing with a coil assembly, a rotor, and a drive shaft extending out of the housing. The chore motor is attached to the cutting deck so that at least a portion of the housing and the drive shaft are positioned in the cutting chamber. The lawn mower further includes a blade coupled to the drive shaft so that the blade rotates within the cutting chamber when the chore motor rotates the drive shaft, and a spring washer coupled between the drive shaft and the blade. Relative rotation between the blade and the drive shaft occurs in response to a torque on the blade exceeding a threshold value.

摘要： A cell module assembly includes a top frame, a bottom frame, multiple lithium-ion battery cells, a top collector plate, a bottom collector plate, and a curable adhesive. The top frame includes protrusions that define first multiple pockets. The bottom frame includes protrusions that define second multiple pockets axially aligned with the first multiple pockets. Each of the first and the second multiple pockets have multiple windows. The battery cells are received within a pocket in each of the first and second multiple pockets. The top collector plate is coupled to the top frame and includes multiple apertures above the first multiple pockets. The bottom collector plate is coupled to the bottom frame. The top collector plate and the bottom collector plate are electrically connected to the battery cells. The curable adhesive is received within each window in the first multiple pockets and couples each battery cell to the top frame.
