Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinet technology, specifically an intelligent battery swapping cabinet. Background Technology

[0002] In urban short-distance travel and last-mile logistics delivery, electric two-wheelers and electric tricycles have achieved widespread adoption due to their flexibility, efficiency, and low cost, becoming core tools for daily commuting and for logistics companies to complete "last-mile" deliveries. However, the range of these electric vehicles remains a key bottleneck restricting user experience. Long battery charging times and limited range have fueled intense range anxiety, making rapid and convenient charging a critical pain point for the industry. Against this backdrop, intelligent battery swapping stations have emerged with their efficient "swap and go" charging model—users no longer need to wait for a lengthy charging process; they can quickly restore their vehicle's range simply by swapping in a fully charged battery, effectively solving the range anxiety problem and thus rapidly becoming the mainstream solution in the current electric vehicle charging field.

[0003] Utility model patent with publication number CN211943000U discloses an intelligent battery swapping cabinet, including a cabinet body, a top maintenance door, upper battery compartment door A, upper battery compartment door B, upper battery compartment door C, lower battery compartment door D, lower battery compartment door E, a middle maintenance door, a bottom maintenance door, fixed feet, casters, an exhaust fan, a partition, a guide rail, a charger, a control board mounting bracket, a heating plate, an ultraviolet lamp, a side insulation plate A, and a side insulation plate B. Fixed feet are symmetrically connected to the bottom of the front and rear ends of the cabinet body by bolts. Four casters are symmetrically fixed on the bottom surface of the cabinet body and are fixedly connected to the bottom surface of the cabinet body by bolts. An exhaust fan is symmetrically fixed on the upper part of the rear end of the cabinet body, and the exhaust fan adopts a dual-fan design.

[0004] The smart battery swapping cabinets described in the aforementioned patents primarily rely on exhaust fans for heat dissipation. However, each battery compartment is not connected to the internal structure of the cabinet. During charging, batteries continuously generate heat. Due to the isolation design between the battery compartments and the cabinet interior, the exhaust fans can only dissipate heat from the overall internal space of the cabinet, failing to effectively cool the individual battery compartments. This causes the heat generated by the batteries to easily accumulate within the compartments, affecting charging efficiency and battery lifespan. Furthermore, this heat buildup can lead to battery overheating and damage, and even trigger serious safety accidents such as fires and explosions, significantly limiting the safety, reliability, and market value of the smart battery swapping cabinets.
