Disclosed is a children's vehicle, which comprises a main vehicle frame extending in a front-rear direction, two front wheels disposed respectively on the left and right sides of the bottom-front portion of the main vehicle frame, a joystick extending upwardly inclined from front to rear, a sliding member slidingly disposed on the main vehicle frame, and a connecting bar rotatably connected between the joystick and the sliding member, wherein a lower portion of the joystick is connected to rotatably a front portion of the main vehicle frame. 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 small electric vehicle includes: left and right motors connected respectively to the left and right driving wheels in an individually power-transmissible manner; an operation unit that includes a joystick-type operation element; a control unit that controls the left and right motors according to an amount of operation on the operation element; and a travel permission switch that permits control of the left and right motors through the operation element, and is configured: to control the left and right motors, based on a target vehicle speed provided by an operation position of the operation element in an on state of the travel permission switch, and to activate a control parameter selection mode and allow at least one control parameter including a maximum speed to be changed when the operation element is subjected to a tilting operation for a predetermined time period in an off state of the travel permission switch.

Provided is a method of controlling charging and discharging vehicle through a charging station executed by a control device. The method includes: when a first vehicle placed in a first charging station is released, identifying the time the first vehicle is released and a residual quantity of the battery and renewing state information of the first vehicle; when the first vehicle is returned to the first charging station, identifying the time the first vehicle is returned and a residual quantity of the battery and renewing state information of the first vehicle; comparing the residual quantity of the battery identified when the first vehicle is released to the residual quantity of the battery identified when the first vehicle is returned based on the state information of the first vehicle and calculating the amount of the battery used in the first vehicle; estimating and calculating an aging degree of the battery of the first vehicle based on the number of times the battery of the first vehicle is charged and discharged and the amount of the battery of the first vehicle used, after charging and discharging detail is identified through the state information of the first vehicle; setting a charging upper limit and a discharging lower limit for the battery of the first vehicle based on the battery aging degree of the first vehicle; and determining whether the battery of the first vehicle needs to be replaced based on the charging upper limit and the discharging lower limit.

A battery charging management system includes a plurality of sockets combinable with a plurality of devices onto which a plurality of battery packs are mounted; a binding controller configured to receive state information of the plurality of battery packs from the plurality of devices, determine a priority of the plurality of devices to be allocated to the plurality of sockets according to a charging strategy selected based on the state information, and allocate one of the plurality of sockets to one of the plurality of devices or releasing the allocating; a charging controller configured to control charging of the plurality of battery packs of the plurality of devices electrically connected to a charging circuit based on the state information received by the binding controller; and a distributor configured to switch an electrical connection between the charging circuit and the plurality of battery packs.

A mobility for storing a personal transportation includes a first storage unit formed on a side of the mobility and configured for storing the personal transportation therein without folding thereof; a second storage unit formed on a side of the mobility and configured for storing the personal transportation therein after the personal transportation is folded; a controller configured to control the first storage unit and the second storage unit in response to a mobility user's request; and a server configured to receive information related to whether the first storage unit and the second storage unit are used, and a remaining battery capacity, use time, and movable distance of the stored personal transportation from the controller, and to communicate with the mobility user.

A portable energy-saving and environment-friendly electric vehicle is light in weight, small in volume, convenient in electricity charging, and disassemble to be collected into a backpack for portability. The backpack is further furnished with a crank-handle generator to fulfill manpower electricity generation and working out simultaneously. This energy-saving and environment-friendly electric vehicle is mainly consisted of two adjustable skateboards and a support rod for adjusting speed and connecting a battery set. The battery set can be conveniently replaced roadside or domestically. In a situation of power out, manpower can be used to charge the battery set. Thus, the situation of power out to shut down the electric vehicle can be met. In addition, the battery set associated with the generator is reliable for charging mobile phones and computers.

An auto-balancing transportation device having a wheel structure and foot platforms that pivot between an in-use and a stowed position. The pivot axis for each platform is provided within the wheel structure so that the force exerted by a rider when stepping on a foot platform is applied to the wheel structure at a point within the wheel structure, as opposed to external to it, which is unstable and may cause the device to tip over.
