This disclosure describes an assembly for gas (e.g., compressed natural gas) storage. The assembly includes multiple gas storage tanks, with each tank coupled to a separate sub-assembly that includes a pressure gauge, shutoff valve, and pressure relief device (PRD), providing for independent pressure monitoring, shutoff, and pressure relief for each of the tanks.

A refuse collection vehicle includes a wheeled chassis, a battery pack, a refuse collection body, and a DC-DC converter. The wheeled chassis has an electric propulsion motor connected to a road wheel of the chassis. The battery pack has multiple battery cells and provides electrical power to the propulsion motor. The refuse collection body is carried by the chassis and defines a refuse storage compartment. The refuse collection body includes a refuse packer driven by an electric packer motor. The refuse collection body also includes a powered tailgate driven by an electric tailgate motor. The DC-DC converter is connected to the battery pack and provides electrical power to the electric packer motor and to the electric tailgate motor at one or more DC voltages different than a voltage provided by the battery pack to the DC-DC converter.

A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

A refuse vehicle includes a battery and electric power take-off system that includes a second motor configured to convert electrical power into hydraulic power, an inverter configured to provide electrical power to the second motor from the battery, a heat dissipation device in thermal communication with the inverter, wherein the heat dissipation device includes a plurality of conduits and a thermal fluid pump configured to pump cooling fluid through the plurality of conduits, a thermal sensor configured to detect thermal energy within the inverter, a flow meter configured determine a flow rate of cooling fluid through the plurality of conduits, and a controller configured to receive data from the thermal sensor and the flow meter and provide operating parameters to the heat dissipation device.

A refuse vehicle including a chassis a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system, and an auxiliary power system comprising a reservoir to hold a hydraulic fluid, and a hydraulic pump powered by an electric motor, wherein the hydraulic pump pressurizes the hydraulic fluid to power one or more actuators, and wherein at least one of the electric energy system or the auxiliary power system is configured to provide power to a carry can.

A refuse vehicle includes a chassis, a body, and a plurality of battery cells. The chassis includes a right frame member and a left frame member spaced apart in a lateral direction and extending lengthwise in a longitudinal direction. The body is coupled to the chassis. The plurality of battery cells are longitudinally disposed along the chassis, positioned between the right frame member and the left frame member.

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.

A joystick control system for a refuse vehicle includes multiple joystick input devices, and a single controller. The single controller is configured to receive a user input from one or more of the multiple joystick input devices. The controller is also configured to identify which of the joystick input devices provide the user input. The controller is also configured to generate control signals, in response to receiving the user input, for one or more controllable elements of the refuse vehicle based on which of the joystick input devices provides the user input and the user input. The controller is also configured to provide the control signals to the one or more controllable elements of the refuse vehicle to operate the one or more controllable elements of the refuse vehicle according to the user input.
