[0076] The working principle and technical effects of the above technical solution are as follows:

[0077] In a modular energy storage box for a mobile charging vehicle of the present invention, after the power motor 29 is started, it can drive the power shaft to rotate, and the power shaft drives the bevel gear 1 26 to rotate through the bevel gear 28. When the bevel gear 1 26 rotates, it can drive the spoiler blade 27 to stir the coolant in the cooling chamber through the rotating circular tube 25, so that the coolant moves in the cooling chamber, which is convenient for the coolant at different positions to fully contact and exchange heat with the outer side of the charging box 5, effectively ensuring the circulating cooling and heat exchange effect.

[0078] One end of the rotating circular tube 25 inserted into the energy storage box 1 is fixedly connected to the suction impeller 30, and the suction impeller 30 is located between the multiple battery cells 3. A plurality of suction holes 31 with suction filters are evenly arranged on the rotating support 10, and each suction hole 31 is located between two supporting grooves; the top surface of the energy storage box 1 is provided with a plurality of exhaust holes with dust-proof filters.

[0079] When the rotating circular tube 25 rotates, it can also drive the suction impeller 30 to rotate in the energy storage box 1, so that the outside air is sucked into the energy storage box 1 through the multiple suction holes 31 on the rotating support 10, and discharged through the exhaust holes on the top surface of the energy storage box 1, so that the gas flows in the energy storage box 1, and multiple unused battery cells 3 in the energy storage box 1 can be blown to improve the internal air condition, enhance the air circulation effect, and reduce the probability of heating in high temperature weather. Each suction hole 31 is located between two supporting grooves, so that the air can effectively flow between adjacent battery cells 3, thereby improving the gas flow effect.

[0080] Multiple exhaust holes on the top surface of the energy storage box 1 are connected to arc-shaped air ducts 32, and the multiple arc-shaped air ducts 32 are arranged toward the multiple heat dissipation fins on the outer side of the cooling box 21, so that gas can blow to the cooling box 21. Since the battery cells 3 in the energy storage box 1 are not in use, the heat generation can be ignored. At this time, the airflow is controlled to gather through the arc-shaped air ducts 32 to blow to the cooling box 21, which can be used to cool the coolant in use in the cooling box 21, thereby improving the circulation cooling effect of the coolant.

[0081] The inner side surface of the arc-shaped box cover 7 is slidably fitted on the outer side surface of the battery cell 3, and anti-slip protrusions 8 are provided at the upper and lower ends of the outer side surface of the arc-shaped box cover 7. A snap-in groove is provided on the outer side surface of the energy storage box body 1 for snapping into the anti-slip protrusion 8 at the upper end of the outer side surface of the arc-shaped box cover 7 to prevent the battery cell 3 from getting stuck during installation and improve the convenience of installing the battery cell 3. Anti-slip protrusions 8 are provided at the upper and lower ends of the outer side surface of the arc-shaped box cover 7 to prevent the arc-shaped box cover 7 from falling off.

[0082] The adapter connector 6 includes: a conductive sheet, which is electrically connected to the charging gun through a wire, an insulating plate fixed to the top of the conductive sheet, and two connecting posts for connecting the positive terminal and the negative terminal of the battery cell 3 fixed to the bottom of the conductive sheet. The middle parts of the two connecting posts are slidably arranged on the top surface of the charging box 5, and a tensioning spring is connected between the top surface of the charging box 5 and the insulating plate. When the positive terminal and the negative terminal of the battery cell 3 are in contact with the two connecting posts at the bottom of the conductive sheet, power can be supplied. In order to improve the power supply stability, a tensioning spring is connected between the top surface of the charging box 5 and the insulating plate, so that the two connecting posts remain in close contact with the positive terminal and the negative terminal of the battery cell 3 under the action of elastic force, thereby ensuring the power supply effect.
