Described is a telehandler (1) equipped with at an electric propulsion motor and with several containment compartments (100) for housing means (200, 300) for powering the motor. A compartment (100) is provided with an access opening to allow a user to insert or extract a source of electricity (200, 300) included in the power supply means. A plurality of electric batteries (200) is made available, each designed to be inserted in one of the compartments (100). An electricity generator apparatus (300) is provided for insertion in one of the compartments (100). The telehandler (1) is equipped with the following alternative power supply configurations: a fully electrical configuration wherein the power supply means comprise only one or more electric batteries (200); and a hybrid configuration wherein the power supply means include the electricity generator apparatus (300).

A system in a vehicle includes a current regulator to obtain current commands from a controller based on a torque input and provide voltage commands and an inverter to use the voltage commands from the current regulator and direct current (DC) supplied by a battery to provide alternating current (AC). The system also includes an electric traction motor to provide drive power to a transmission of the vehicle based on injection of the AC from the inverter. The current regulator adjusts parameters of a transfer function implemented by the current regulator, based on feedback of an input to and an output from the electric traction motor to achieve the AC corresponding with the torque input in no more than two control cycles.

This relay unit includes: a first bus bar; a relay electrically connected to the first bus bar; and an apparatus cover for covering the first bus bar and the relay. The apparatus cover includes: an upper member in a box shape having a covered upper end, the upper member having an opening formed in a lower end; and a lower member bonded to the upper member such that the opening of the upper member is covered with the lower member. The lower member is formed of a resin having heat conductivity that is higher than that of the upper member. The first bus bar is connected to the lower member via a first inner heat conductive sheet such that heat can be transferred to the lower member, said first inner heat conductive sheet being disposed between the first bus bar and the lower member.

A power convertor has a casing and a power conversion circuit arranged in an internal chamber of the casing. The casing has a first wall member as a specific side wall. A plurality of connector opening parts are formed in the first wall member. At least two of the plurality of connector opening parts formed in the first wall member are arranged at different positions facing a different direction from each other.

A vehicle radiator assembly includes: a common inlet tank having a high temperature inlet chamber and a low temperature inlet chamber; a common outlet tank spaced apart from the common inlet tank and including a high temperature outlet chamber and a low temperature outlet chamber; a high temperature radiator core including a plurality of high temperature tubes connecting the high temperature inlet chamber and the high temperature outlet chamber, and a plurality of high temperature cooling fins arranged with the plurality of high temperature tubes; a low temperature radiator core including a plurality of low temperature tubes connecting the low temperature inlet chamber and the low temperature outlet chamber, and a plurality of low temperature cooling fins arranged with the plurality of low temperature tubes; and a bimetal interposed between the high temperature radiator core and the low temperature radiator core.

Methods and systems are provided for using energy harvesting modules as a means for providing energy to power an electrical load and/or as a means for monitoring an operational state of a component or components to which the energy harvesting module is coupled. In one example, a method includes, via a controller, monitoring an actual amount of energy generated by an energy harvesting module attached to a mounting structure that is used to secure a torque-supplying machine to a frame, comparing the actual amount to an expected amount, and indicating degradation of the mounting structure and/or the torque-supplying machine based on the comparing. In this way, the energy harvesting modules may both power electrical loads and simultaneously serve as a monitor for component degradation.
