A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To allow easy and convenient access to empty portable electrical energy storage device compartments within the vehicles, if the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as a key fob or other wireless device of a user, an empty portable electrical energy storage device compartment that is closed or locked, is unlocked, unlatched or opened automatically. Also, if the portable electrical energy storage device compartment is in another desired state to have the compartment unlocked, such as having a portable electrical energy storage device in the compartment that has a charge level below a particular threshold, the compartment will likewise be unlocked, unlatched or opened automatically.

To provide a technique for reliably acquiring a required braking power during travel and for efficiently using a regenerative power generated during braking. A work vehicle calculates a regenerative power outputted from an electric motor and a target hydraulic driving power for driving a hydraulic pump, supplies the regenerative power to the generator motor operating as a motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and supplies the regenerative power to the generator motor operating as the motor and makes an exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.

In an all-wheel drive arrangement with low input torque especially for the skid-steer loaders controlled by a control unit, made up of battery, frequency converter, electric joystick and/or electro-hydraulic switchgear, both sides of the vehicle control include at least two wheels, each wheel connected to a planetary gearing. The gearing equipped with the infinite gear member (e.g. belt, chain) transfers the torque from the electric motor to each wheel on one side of the vehicle controlled, whereby the planetary gear directly drives the particular wheel.

A device which is configured for controlling a vehicle drive (40) for traction of a vehicle has a drive control apparatus and a monitoring apparatus. In order to ensure a high degree of safety when using the vehicle drive during rapid deceleration of the vehicle, the monitoring apparatus provides a traction release control signal value to the drive control apparatus, under the effect of which the drive control apparatus is enabled to control the vehicle drive, if, in addition to a traction release request signal value due to a rapid deceleration request and an additional traction lock request signal value due to a traction lock request, an additional traction release request signal value due to a traction release condition has effect on the monitoring apparatus. There is also described a vehicle with such a device and to a method for controlling a vehicle drive for traction of a vehicle.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. The charging and distribution machines may distribute portable electrical energy storage devices of particular performance characteristics and other attributes based on customer preferences and/or customer profiles. The charging and distribution machines may provide instructions to or otherwise program portable electrical energy storage devices stored within the charging and distribution machines to perform at various levels according to user preferences and user profiles.

A working device to be connected to a traveling vehicle having a prime mover, the working device being configured to perform an agricultural work, includes a working portion to rotate to perform an agricultural work, an electric motor to be driven by electric power, a power transmission mechanism to which power generated by the electric motor is inputted, configured to transmit the power to the working portion; and a regeneration resistor to consume a regenerative power generated in the electric motor, the regeneration resistor being arranged at a position to be cooled by wind generated by rotation of the working portion.

A resistor includes an elongated cylindrical body having nodes and elongated members. The elongated members interconnect the nodes to form openings between the nodes and the elongated members for the flow therethrough of a cooling fluid. The body is configured to receive electric current from a powered system and to conduct and provide electric resistance to the electric current to dissipate at least part of the electric current as heat from the body. The body also is configured to be coupled with at least one other resistor of the powered system in one or more of a parallel or series arrangement in an electric circuit.
