The accessory module is configured to receive mechanical energy provided by the electric motor and provide at least one of electrical energy or fluid energy.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a pump system, and a driveline. The driveline includes a front axle coupled to the chassis, a rear axle coupled to the chassis, an energy storage system, an engine coupled to the chassis, and an electromechanical device coupled to the chassis, the engine, and at least one of the front axle or the rear axle. The driveline is a dual drive driveline such that, during any and all modes of operation of the driveline, the electromechanical device is incapable of or prevented from charging the energy storage system at any time when driven by the engine.

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

In an embodiment, a motor guidance component is configured to guide a dislodged electric motor away from one or more protected areas of the electric vehicle in response to crash forces. In a further embodiment, the motor guidance component may be configured to guide the one dislodged electric motor in an upwards direction (e.g., above the one or more protected areas) or in a downwards direction (e.g., below the one or more protected areas).

A retrofit electric drive apparatus is provided for converting a fossil fuel fitted motorcycle into an electric-powered motorcycle. In an embodiment, the apparatus includes a housing supporting electric drive train components. At least a portion of the housing is shaped to congruously match a portion of the motorcycle frame and reside within an envelope defined by the motorcycle frame.

In another embodiment, the retrofit electric drive apparatus comprises a housing including a first side element and a second side element, the first side element connected to the second side element at a predetermined spacing to create an internal space. The housing is shaped to reside within an envelope defined by the motorcycle frame and has at least a portion congruous with a portion of the motorcycle frame defining the envelope.

In another embodiment, the retrofit electric drive apparatus comprises a housing kit.

An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

In an embodiment, a battery module fixation arrangement includes gaps arranged between fixation recesses and fixation pins. Upon insertion of a battery module into a battery module compartment, each gap is at least partially filled with a curing material that cures after the insertion. In a further embodiment, the fixation recesses may include cartridges that comprise a foam material along with multiple components that mix to form the curing material after the insertion.

In an embodiment, an expansion component (e.g., expanding foam element, inflatable pad, a pneumatic or hydraulic mechanism, etc.) is arranged inside of a battery module compartment (e.g., on a bottom interior surface of the battery module compartment). A battery module is inserted into the battery module component and is fixated, or secured, within the battery module compartment at least in part based upon the expanding component which starts to expand or continues to expand after the insertion. In a further embodiment, the battery module may be removed from the battery module compartment after a contraction function (e.g., collapse of the foam element, deflation of the inflatable pad, etc.) of the expansion component is initiated.

In an embodiment, a battery module compartment chamber is configured for deployment with one or more other battery module compartment chambers within a battery module mounting area of an energy storage system. The battery module compartment chamber includes exterior walls and at least one interior firewall that define multiple battery module compartments into which battery modules may be inserted and/or removed. Each battery module compartment includes an insertion-side configured to be closed via a respective insertion-side cover to seal the respective battery module compartment. In a further embodiment, the battery module compartment may be stacked longitudinally with one or more other battery module compartment chambers to form a battery module mounting area. A type of the battery module compartment chamber and/or a number of longitudinally stacked battery module compartment chambers may be selected to satisfy a size requirement for the battery module mounting area.

An embodiment is directed to a battery module mounting area of an energy storage system. The battery module mounting area includes a first set of battery module compartments arranged along a first longitudinal side of the battery module mounting area, and a second set of battery module compartments arranged along a second longitudinal side of the battery module mounting area. Each battery module compartment in the first and second sets of battery module compartments includes an insertion-side through which a battery module is configured to be inserted into the battery module compartment and/or removed from the battery module compartment. The insertion-side of each battery module compartment in the first and second sets of battery module compartments is configured to be closed via an insertion-side cover to form a battery housing with a closed compartment profile that is characterized by each battery module compartment being sealed from at least one other battery module compartment in the battery housing.
