constant current: 50.0A, end voltage: 40.5V;
a maximum sustained discharge current; 100.0A 25 +/-3 ℃;
maximum output power: 2.4KW 25 +/-3 ℃.
The 8 lithium batteries connected in series can also output 24V to the outside, and a 24V output port (not shown in the figure) is also formed on the box body 1.
The 4 lithium batteries are connected in series to output 12V voltage to the outside, and the box body 1 is also provided with a 12V output port (not shown in the figure).
2 of them lithium cell are established ties and are connected together and can to the voltage of 5V of external output to offer 12V output port (not shown in the figure) on box 1 equally, through the different series connections to the lithium cell, realize multiple voltage output.
The above voltage outputs are set according to actual use requirements.
The upper end of the box body 1 is rotatably provided with a rotating plate through a rotating shaft, and the rotating plate is fixedly provided with a solar cell panel 4, so that the remaining rotating plate of the solar cell panel 4 forms an integral structure. The rotating plate has a bearing effect on the solar cell panel. In the case of sunlight, the solar cell panel 4 can generate electricity.
The outer side wall of the box body 1 is also provided with a solar charging port 8 which is connected with a solar cell panel 4 by a wire to charge the battery pack 2.
The box cover is provided with a shaft hole matched with the rotating shaft, the rotating shaft is directly installed in the shaft hole, sufficient friction force exists between the rotating shaft and the inner side of the shaft hole, and the friction force forms damping force, so that the solar cell panel 4 can be stopped at any position after the external force is removed in the rotating process, and the state is kept still.
When the angle of the solar cell panel 4 is adjusted, the angle is determined according to the angle of sunlight and basically perpendicular to the sunlight, and the solar cell panel 4 can be rotated by hands directly when the angle is rotated.
An anode charging and discharging port interface 6 and a cathode charging and discharging interface 7 are arranged on the outer side of the box body 1, as shown in fig. 1-2, the anode charging and discharging port interface 6 and the cathode charging and discharging interface 7 can output voltage and current outwards, and meanwhile, when the battery pack 2 is not charged, the battery pack 2 can be charged from the anode charging and discharging port interface 6 and the cathode charging and discharging interface 7.
Because group battery 2 can produce the heat at the during operation, consequently still seted up ventilation hole 3 at the lateral surface of box 1, ventilation hole 3 can make the inside circulation of air of box 1, dispels the heat to group battery 2.
Besides the damping force, the position of the solar panel 4 can also be adjusted by the support rod 5.
The bottom of the rotating plate is provided with a plurality of clamping grooves, and the other end of the supporting rod 5 can be clamped in the clamping grooves.
The manual rotation goes out solar cell panel 4 to suitable position, then rotates bracing piece 5 for the other end of bracing piece 5 is in the same place with the draw-in groove card of solar energy rear side, and bracing piece 5 can support solar cell panel 4's rear side, thereby makes solar cell panel 4's angle remain motionless. As shown in fig. 3.
The standing groove has been seted up to the upper end of case lid, and bracing piece 5 is put at ordinary times and all is located the case lid with the rotor plate is put at ordinary times, therefore solar cell panel 4's angle modulation scope is limited, the contained angle of 60 at the maximum.
The upper end at box 1 is seted up to ventilation hole 3, and when the upper end laminating of rotor plate and box 1 was in the same place, the rotor plate got up ventilation hole 3 closed, and ventilation hole 3 is out of work. When the ventilation holes 3 are needed to work, the rotating plate and the solar cell panel 4 only need to be rotated upwards, so that gaps are reserved between the rotating plate and the box body 1, and the ventilation holes 3 are convenient to open and can ventilate and radiate. When not in use, the vent holes 3 are in a closed state, and dust can be prevented from falling into the interior of the case 1 through the vent holes 3.
And under the condition that has sunshine, the ventilation hole is located the below of rotor plate, can also avoid sunshine to pass the ventilation hole and shine in the inside of box 1, avoids lithium cell and internals to shine sunshine, can reduce the ageing of internals.
Solar charging port 8 is seted up in the upper end of box 1, when not using solar charging, solar charging port 8 is sheltered from by the rotor plate, can avoid the dust to cause the influence to solar charging port equally, avoids solar charging port 8 to be blockked up or because the dust leads to contact failure's the condition to appear.
In a further embodiment, in order to better adjust the angle between the rotating plate and the solar panel 4, so that the angle of rotation of the solar panel 4 is larger, the supporting rod 5 includes a fixing rod 51 and a sliding rod 55, one end of the fixing rod 51 is provided with a sliding slot 52, one end of the sliding rod 55 is located in the sliding slot 52 and can slide inside the sliding slot 52, a waist-shaped slot 53 is provided on the sliding rod 55, a fastening bolt 54 is installed on the opening side of the sliding slot 52 through a thread, the fastening bolt 54 penetrates through the waist-shaped slot 53, and when the fastening bolt 54 is tightened, pressure can be generated on the sliding rod 55, so that the position of the sliding rod 55 is kept fixed and cannot slide, and thus the relative length between the fixing rod 51 and the sliding rod 55 cannot be changed.
The bottom of the fixed rod 51 is fixedly provided with a rotating shaft and is rotatably arranged together with the upper end of the box cover, the fixed rod 51 can drive the sliding rod 55 to rotate around the rotating shaft together, and the upper end of the sliding rod 55 is fixedly provided with a clamping shaft matched with the clamping groove. Because the supporting rod can be adjusted to be long, only one clamping groove is needed to be arranged at the position, as shown in fig. 3, the clamping groove is of a U-shaped structure, and the opening side of the clamping groove is parallel to the bottom of the rotating plate.
When the angles of the rotating plate and the solar cell panel 4 are adjusted, the rotating plate and the solar cell panel are firstly rotated, then the fixed rod 51 is rotated out, the fastening bolt 54 is firstly unscrewed, the buckle of the sliding rod 55 is clamped into the clamping groove, then the sliding rod 55 is slid, the overall length of the supporting rod is changed, so that the angle of the solar cell panel 4 is changed, and the angle and the position of the solar cell panel 4 can be fixed by screwing the fastening bolt 54 after the adjustment is completed.
