  • Patent number: 11787387
    Abstract: A thermal management system for an energy storage container includes an enclosed compartment containing an energy storage unit, an air temperature control unit configured to cool an interior of the enclosed compartment, and at least one inverter connected to a coolant circuit, which is separate from the air temperature control unit, and configured to be cooled by a coolant in the coolant circuit. The thermal management system also includes a radiator located outside of the enclosed compartment, the radiator being connected to the coolant circuit, wherein the coolant in the coolant circuit flows through the radiator, and at least one fan located alongside the radiator, outside of the enclosed compartment, the at least one fan being configured to blow air across the radiator to cool the coolant flowing through the radiator.

  • Publication number: 20070046070
    Abstract: A vehicle cab includes a floor, a roof, a front support operably coupling the floor and the roof, and at least two side supports operably coupling the floor and the roof. The vehicle cab further includes a door operably coupled to one of the at least two side supports. The door extends from adjacent the floor toward the roof. The door includes a window extending in a substantially uninterrupted manner from a lower edge of the door toward an upper edge of the door. The front support is located along a centrally-located, longitudinal axis of the vehicle cab, such that when the door is in a closed position, the door extends along a line oriented at an angle oblique with respect the longitudinal axis of the vehicle cab between the front support and the side support.
