The invention discloses a battery tank structure of an unmanned aerial vehicle (UAV) and relates to the technologies of battery tank structures of UAVs. The battery tank structure can solve the problem of large space occupation of a battery tank of an existing UAV. A main battery tank body is of a rectangular structure, is placed in the middle of a UAV body, the side wall of the tank body is provided with a plurality of positioning holes, and a battery locking mechanism is fixed by the positioning holes and fixedly connected to a battery after the battery is inserted into the battery tank; byfixing the battery locking mechanism to the positioning holes in different positions, the position of the battery in the whole UAV body is adjusted, and correspondingly the position of the gravity center of the UAV body is adjusted. The structure is mainly used for UAVs.

To provide a disaster power supply device for a ship that can be charged with surplus power generated by an outboard motor without interfering with the operation of a small ship, and can be carried to an evacuation site or the like in the event of a disaster and used as an emergency power supply. [Solution] A marine disaster power supply device 1 that is connected to the main battery 100 of a small boat to charge excess power and be used as a power source in the event of a disaster. It comprises a disaster battery 2 that charges excess power from the power supplied from the outboard motor 300 to the main battery 100, an isolator 3 that is connected to the main battery 100 and switches charging to the disaster battery 2 when the main battery 100 is fully charged, an outlet 4 that is connected to the disaster battery 2 via the isolator 3 and enables the power charged in the disaster battery 2 to be supplied to the outside, and a portable housing 5 that incorporates the disaster battery 2, isolator 3 and outlet 4 and is equipped with a handle 53 for carrying.

The invention relates to an electric shovel loader (1) comprising: - a chassis (2) supported by movement members (4), - a turret (3) mounted so as to be free to rotate on the chassis about a vertical axis (X) distant from the lateral edge (5) of the chassis by a length d, the turret having a radius of rotation Ri; - an articulated arm (6) fixed to the turret; - an electric motor configured to actuate the rotation of the turret, the movements of the articulated arm and / or the transmission of the movement members; - a main battery (9) for powering the electric motor, the main battery being removably mounted on the chassis or the turret while being comprised, as viewed along the vertical axis (X), in a circle of radius R2 centred on the vertical axis (X), the ratios of R1 to d and of R2 to d being less than or equal to 1.40.

The invention relates to an electric excavator (1) comprising: - a chassis (2) having a housing (7) configured to receive a main battery pack (6); - a turret (3) freely mounted for rotation on the chassis and having an articulated arm (4); - an auxiliary battery pack (13) configured to power an auxiliary power circuit (30) of the excavator, which enables the rotation of the turret and the use of the articulated arm so as to deposit the main battery pack by means of the articulated arm. The invention also relates to a method for autonomously depositing and a method for autonomously positioning a battery pack between a position placed in a housing of an electric excavator and a position placed outside the housing, the electric excavator having a turret freely mounted for rotation on a chassis and supporting an articulated arm.

The application relates to a charging and discharging control circuit and a power consumption device. The charging and discharging control circuit comprises a charging control module connected with a backup battery; a switching switch module connected with the charging control module and a main battery for powering a load, the switching switch module being used in a first state or a second state, wherein the first state is a charging loop for connecting the charging control module and the main battery to connect the backup battery to power the main battery, and the second state is a discharging loop for connecting the main battery and the load; and a discharging control module connected with the main battery and the switching switch module. The application can automatically switch to the backup battery to charge the main battery, thereby solving the problem of insufficient battery power.

Short-radius electric excavator comprising a removable battery. The invention relates to an electric excavator (1) comprising: - a chassis (2) supported by drive elements (4), - a turret (3) freely mounted for rotation on the chassis about a vertical axis (X) located a distance d from the lateral edge (5) of the chassis, the turret having a radius of rotation R1; - an articulated arm (6) fixed to the turret; - an electric motor configured to drive the rotation of the turret, the movements of the articulated arm and / or the transmission of the drive elements; - a main battery (9) for powering the electric motor, the main battery being removably mounted on the chassis or the turret and being contained, viewed along the vertical axis (X), within a circle of radius R2 centered on the vertical axis (X), the ratios of R1 to d and R2 to d being less than or equal to 1.40.
