  • Patent number: 11161415
    Abstract: A refuse vehicle includes a chassis supporting a plurality of wheels, a battery supported by the chassis and configured to provide electrical power to a first motor, and an electric power take-off system coupled to the vehicle body. The electric power-take-off system includes a second motor configured to convert electrical power received from the battery into hydraulic power, an inverter configured to provide electrical power to the second motor from the battery, a heat dissipation device coupled to the inverter, a first sensor configured to detect thermal energy within the inverter, and a controller configured to receive data from the first sensor and provide operating parameters to the heat dissipation device, wherein the controller is further configured to determine if the data from the first sensor is greater than a critical operating condition and shut down the electric power take-off system in response.

  • Patent number: 11136187
    Abstract: A refuse vehicle includes a chassis, a battery, a vehicle body, an electric power take-off system, a lifting system, and a disconnect. The chassis supports a plurality of wheels. The battery is supported by the chassis and is configured to provide electrical power to a first motor. Rotation of the first motor selectively drives at least one of the plurality of wheels. The vehicle body is supported by the chassis and defines a receptacle for storing refuse. The electric power take-off system is coupled to the vehicle body and includes a second motor configured to convert electrical power received from the battery into hydraulic power. The lifting system is coupled to the vehicle body and is movable relative to the receptacle using hydraulic power from the electric power take-off system. The disconnect is positioned between the battery and the electric power take-off and is configured to selectively decouple the electric power take-off system from the battery.

  • Publication number: 20210292086
    Abstract: A system for detecting and engaging a refuse can includes at least one sensor coupled to a refuse collection vehicle and configured to detect objects on one or more sides of the refuse vehicle, an actuator assembly coupled to the refuse collection vehicle and configured to actuate to engage the refuse can, and a controller configured to receive first data from the at least one sensor, input the first data to a single-stage object detector, identify, based on an output of the single-stage object detector, the refuse can, and initiate a control action to move the actuator assembly and the refuse collection vehicle to engage the refuse can.

  • Publication number: 20210088036
    Abstract: A pump system includes a pump assembly and a pump controller. The pump assembly includes a housing defining a first volume and a second volume separated by a divider, a first piston dividing the first volume into a first chamber and a second chamber, a second piston dividing the second volume into a third chamber and a fourth chamber, and a piston rod coupling the first piston and the second piston such that a movement of the first piston causes an equal movement of the second piston. The pump controller is configured to alternately supply a first fluid to the second chamber and the fourth chamber to cause the first piston and the second piston to reciprocate within the housing.
