The children's vehicle further comprises first connecting rods, one end of each of which is rotatably connected on the main vehicle frame, and second connecting rods rotatably connected between the first connecting rods and the sliding member, the front wheels are mounted on the other ends of the first connecting rods. When the children's vehicle switches from an unfolded state to a folded state, the joystick is folded close to the main vehicle frame, the second connecting rods drive the first connecting rods to close to the main vehicle frame, and the two front wheels are folded close to the left and right sides of the main vehicle frame. When folded, the children's vehicle is very flat and compact, and the overall height and width thereof are greatly reduced.

A management system is configured to manage a power feed mat that wirelessly feeds power to a movable body. The power feed mat is configured to communicate while it is placed at a prescribed location. This management system includes a monitoring apparatus that monitors communication by the power feed mat and a processing apparatus that performs prescribed processing when the monitoring apparatus senses loss of the communication.

A charge control system includes a lithium battery configured to provide lithium battery power to a set of electrical loads, a user signaling device, and control circuitry coupled with the lithium battery and the user signaling device. The control circuitry is operative to: (A) detect availability of charge from an external charger, (B) in response to detection of the availability of charge from the external charger and prior to controlling the external charger to adjust the amount of charge stored by the lithium battery, perform a set of pre-charging assessment operations, and (C) based on the set of pre-charging assessment operations, provide a user notification via the user signaling device, the user notification indicating whether the lithium battery is properly setup for charge adjustment. When the user signaling device generates the user notification, the user is informed that the utility vehicle is properly connected to the external charger.

The cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to drive the motor; a control device configured to control the motor via the motor drive circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed; and an operation member arranged on the cart and configured to receive an operation by a user. The cart may be configured to operate in a manual mode where the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode were the motor is driven regardless of whether the operation member is on or off. The upper limit travelling speed in the automatic mode may be set lower than the upper limit travelling speed in the manual mode.

A method for operating an electric vehicle has the steps of: determining if at least one of a speed of the vehicle and a speed of an electric motor of the vehicle is zero; in response to the at least one of the speed being zero, determining if a reverse actuator is actuated; in response to the reverse actuator being actuated, starting a timer, then determining if the reverse actuator has been actuated without interruption for a predetermined amount of time; in response to the reverse actuator having been actuated without interruption for the predetermined amount of time, changing an operation mode of the electric motor from one of a forward mode and a reverse mode to another of the forward mode and the reverse mode. An electric snowmobile and other methods for operating an electric vehicle are disclosed.

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor; a driving circuit to transfer power from at least one of the energy storage devices to at least one of the motors; and a charging circuit to charge at least one of the energy storage devices. The riding lawn mower further includes a first identification terminal engageable with the second energy storage device and a second identification terminal engageable with the first energy storage device; the riding lawn mower identifies a type of the energy storage devices through the identification terminals and selectively connects them to the driving circuit and the charging circuit.

A management system for a micro mobility vehicle, includes a service vehicle which is configured to travel along a movement path, wherein the service vehicle includes an accommodation slot for accommodating the micro mobility vehicle, and is configured for exchanging power with the micro mobility vehicle when the micro mobility vehicle is accommodated in the accommodation slot; and a management server configured to communicate with the micro mobility vehicle and the service vehicle to determine a location and a charging amount of the micro mobility vehicle and configured to manage charging and arrangement of the micro mobility vehicle by guiding the service vehicle to allow the micro mobility vehicle to be accommodated in the service vehicle or withdraw the micro mobility vehicle from the service vehicle.

Service vehicles, such as compact service carts (e.g., compact electric vehicles), are described that support a variety of service applications. One such vehicle (100) generally includes a vehicle platform (102) and a service box (104). The vendor box (104) includes canopy doors (106) for each of the sides (110, 112, and 114). The canopy doors (106) are movable between a closed position, where the canopy door (106) encloses the service area (108), and an open position where the canopy doors (106) extend outwardly from the sides 110, 112 and 114. In the open position, the doors (106) thus function as a canopy to provide shade at the service area 108 and maximize the space available for rendering services on the sides (110, 112 and 114) of the box (104). The inventive vehicles are adaptable to meet the needs of a wide variety of service applications including food and beverage applications, medical applications, and others.
