  • Patent number: 9686909
    Abstract: A riding lawn care vehicle may include a battery power source, an electric drive motor, at least one blade drive motor, a current sensor, and a controller. The electric drive motor may be powered by the battery power source. The electric drive motor may be operably coupled to wheels of the riding lawn care vehicle to provide drive power for the riding lawn care vehicle. The at least one blade drive motor may be powered by the battery power source. The at least one blade drive motor may be operably coupled to at least one cutting blade of the riding lawn care vehicle. The current sensor may be disposed to monitor total current drawn from the battery power source. The controller may receive total current data from the current sensor and provide feedback to an operator of the riding lawn care vehicle based on the total current data.

  • Patent number: 9296306
    Abstract: A battery powered vehicle may include a battery power source, an electric drive motor, a charging receptacle, and a drive controller. The electric drive motor may be powered by the battery power source. The electric drive motor may be operably coupled to a wheel of the battery powered vehicle to provide drive power for the battery powered 5 vehicle. The charging receptacle may be configured to enable charging of the battery power source via a battery charging assembly connectable to the charging receptacle. The charging receptacle may include circuitry forming a detection loop closed responsive to operable coupling of the charging receptacle with a charger plug of the battery charging assembly. The closing of the detection loop may generate an indication that the charging 10 receptacle is operably coupled to the charger plug.

  • Publication number: 20140165524
    Abstract: A drive system of a battery powered riding lawn mower is provided. The drive system may include a battery system mountable to a frame, an axle, a drive motor and a differential. The axle may have a wheel on connected to each end of the axle. The drive motor may be mounted to the axle and may be electrically connected to the battery system so that the drive motor is powered by the battery system. The differential may be operatively mounted to the axle and coupled with the drive motor so that when the drive motor is powered, rotational forces are distributed to the axle, thereby rotating each wheel.
