Description

Technical Field

[0002] Mobile charging trucks are new energy vehicles that provide mobile power services, typically used to quickly charge electric vehicles. These trucks are typically equipped with efficient power storage systems and charging equipment, enabling them to replenish power when parked, addressing the potential power shortages that electric vehicles may encounter while driving. Mobile charging trucks can be used at gas stations, parking lots, shopping malls, tourist attractions, and other locations. They can also serve as an emergency power source, providing timely support for electric vehicles that have run out of power and are unable to continue driving. This service is particularly suitable for the early stages of electric vehicle adoption, when charging infrastructure is not yet widely available. Mobile charging trucks can serve as a transitional solution, helping electric vehicle users overcome power anxiety and improving the practicality and convenience of electric vehicles.

[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, the power motor 29 can drive the power shaft to rotate after being started, and the power shaft drives the bevel gear 1 26 to rotate through the bevel gear 2 28. When the bevel gear 1 26 rotates, the turbulent blade 27 can be driven by the rotating circular tube 25 to stir the coolant in the cooling chamber, so that the coolant moves in the cooling chamber, which facilitates 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 is inserted into the energy storage box 1 and fixedly connected to the intake impeller 30. The intake impeller 30 is located between multiple battery cells 3. Multiple intake holes 31 with intake filters are evenly arranged on the rotating support 10. Each intake hole 31 is located between two supporting grooves; the top surface of the energy storage box 1 is provided with multiple exhaust holes with dust 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, thereby drawing external air into the energy storage box 1 through the multiple suction holes 31 on the rotating support 10, and discharging it through the exhaust holes on the top surface of the energy storage box 1, so as to facilitate the flow of gas in the energy storage box 1, and can blow air to multiple unused battery cells 3 in the energy storage box 1, thereby improving the internal air condition, enhancing the air circulation effect, and reducing the probability of heat generation in high temperature weather. In addition, each suction hole 31 is located between two supporting grooves, so that air can effectively flow between adjacent battery cells 3, thereby improving the gas flow effect.

[0080] The multiple exhaust holes on the top surface of the energy storage box 1 are all connected to an arc-shaped air duct 32. 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 the gas can blow toward the cooling box 21. Since the battery cells 3 in the energy storage box 1 are not in use, the heat generated can be ignored. At this time, the airflow is controlled to gather through the arc-shaped air duct 32 to blow toward 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. 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-fit 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 slid 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.
