An off-road vehicle has four wheels and side-by-side driver and passenger seats. At least two of the wheels are driven by an electric motor powered by batteries disposed in the vehicle.

A electric vehicle including a plurality of ground engaging members, a frame assembly supported by the plurality of ground engaging members, the frame assembly including a front frame assembly, a middle frame assembly, and a rear frame assembly, a seating area supported by the middle frame assembly, electric powertrain components supported by the frame assembly to provide power to at least one ground engaging member, and a shrouding assembly.

The four wheel vehicle uses an electric motor (142) for driving the vehicle and a battery unit (160) for supplying electric power to the electric motor. The lower chassis (5) of the vehicle includes a pair of front side frames (10) extending linearly in a fore and aft direction with an upward slant and a progressively increasing lateral mutual spacing from a front part thereof to a rear part thereof, a pair of rear side frames (12) connected to rear ends of the respective front side frames, and extending linearly in a fore and aft direction with an upward slant from a front part thereof to a rear part thereof in continuation of the corresponding front side frames in a mutually parallel relationship, and a plurality of cross members (14, 16, 18, 20, 22) connecting the side frames to each other.

This disclosure provides systems, methods and apparatus for detecting foreign objects. In one aspect an apparatus for detecting a presence of an object is provided. The apparatus includes a resonant circuit having a resonant frequency. The resonant circuit includes a sense circuit including an electrically conductive structure. The apparatus further includes a coupling circuit coupled to the sense circuit. The apparatus further includes a detection circuit coupled to the sense circuit via the coupling circuit. The detection circuit is configured to detect the presence of the object in response to detecting a difference between a measured characteristic that depends on a frequency at which the resonant circuit is resonating and a corresponding characteristic that depends on the resonant frequency of the resonant circuit. The coupling circuit is configured to reduce a variation of the resonant frequency by the detection circuit in the absence of the object.

An electric vehicle is provided. The vehicle includes a frame. A battery and a motor may be secured to the frame, such that the battery powers the motor which drives the vehicle. The vehicle may further include at least one axle including a plurality of wheels. A manual steering mechanism including a steering column is operable to pivot the wheels when the steering column is rotated. An overhead frame protrudes vertically from the main frame. A steering drive shaft is supported by the overhead frame and is operable to pivot the wheels when rotated. A head unit is secured to the steering drive shaft and includes a positive electrode and a negative electrode electrically wired to the battery. The head unit is operable to engage an overhead track. The overhead track transfers electrical power to the positive electrode and negative electrode, thereby recharging the battery and driving the motor while steering the electric vehicle.

Embodiments include methods, for a wireless device, to determine one or more preferred routes for an electric vehicle powered by a battery. Such methods include determining multiple candidate routes from a starting point to a destination. Each candidate route includes one or more segments, each segment associated with a slope and a distance. Such methods include, for each candidate route, estimating a route battery discharge amount and a route duration of travel based on a discharge profile for the battery and the slopes and distances associated with the segments of the candidate route. Such methods include selecting one or more preferred routes, from the candidate routes, based on a current state of charge for the battery, the route battery discharge amounts, and the route durations of travel. Other embodiments include wireless devices configured to perform such methods, and electric vehicles operably coupled to such wireless devices.

In a lawn mower, one power receiving terminal is provided on a surface of the lawn mower, and the other power receiving terminal is disposed in a position where it sandwiches at least a part, such as the upper front portion, of a vehicle body with the one power receiving terminal. This configuration serves to suppress a situation in which moisture establishes electrical continuity between the pair of power receiving terminals.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

A technique provides power-limiting regenerative braking to a utility vehicle. The technique involves detecting that the utility vehicle is moving in a forward direction at a first speed. The technique further involves applying a first regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the first speed. The technique further involves detecting that the utility vehicle is moving in the forward direction at a second speed which is less than the first speed. The technique further involves applying a second regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the second speed. The second regenerative braking power level is lower than the first regenerative braking power level.

An apparatus for detecting a presence of an object includes an inductive sensing coil that is configurable to generate a magnetic field. The inductive sensing coil is configured to have an electrical characteristic that is detectable when generating the magnetic field. The apparatus comprises a controller configured to detect a change in the electrical characteristic and determine a presence of the object based on the detected change in the electrical characteristic.
