The high voltage cable is routed through one or more of the at least one of the torque box or the water tank, or the high voltage cable is routed along a notch defined by one or more of the at least one of the torque box or the water tank.

An electrified fire fighting vehicle includes a chassis defining a longitudinal length of the electrified fire fighting vehicle, a first high voltage component positioned at a first location along the longitudinal length, a second high voltage component positioned at a second location along the longitudinal length, and a raceway assembly. The raceway assembly includes a conduit and a high voltage cable. The high voltage cable provides power between the first location and the second location. To facilitate thermally regulating the high voltage cable, at least one of (a) the conduit defines a plurality of vents, (b) the raceway assembly includes a cooling element disposed within the conduit, or (c) the conduit comprises a thermally conductive material.

A high voltage system for an electrified vehicle includes a first high voltage component, a second high voltage component, and a high voltage cable. The high voltage cable provides power between a first location of the first high voltage component and a second location of the second high voltage component. The high voltage cable includes a core, a sheath disposed around and along the core, and one or more detection layers at least one of (a) disposed around and along the sheath or (b) disposed within the sheath. The one or more detection layers are configured to facilitate detecting at least one of (a) damage or wear to the sheath or (b) a location of the damage or wear along the sheath.

An electrified vehicle includes a chassis having a longitudinal length of at least 20 feet and an energy storage system. The energy storage system includes an enclosure coupled to the chassis, a battery pack positioned within the enclosure, a power distribution system positioned within the enclosure, a first wiring harness positioned entirely internal to the enclosure where the first wiring harness electrically couples the battery pack to the power distribution system, and a second wiring harness. A first portion of the second wiring harness is positioned internal to the enclosure and a second portion of the second wiring harness is positioned external to the enclosure. A maximum external length of any cable of the second wiring harness external to the enclosure is less than 25% of the longitudinal length.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis rearward of the cab, an electric motor coupled to the chassis, and an energy storage system positioned between the cab and the body. The energy storage system includes a rack, a battery pack, and a power distribution system. The rack extends upward from the chassis. The rack defines an interior chamber.

A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.
