Description

Technical Field

[0001] This utility model relates to the field of mobile power supply technology, and in particular to a portable high-capacity mobile charging station. Background Technology

[0002] The charging business model refers to a model where electric vehicle users choose to directly charge their vehicle's battery at a fixed charging station or charging pile when the vehicle's battery is about to run out. This is the primary business model considered for electric vehicle charging stations. Under this model, electric vehicle users consume electricity instantly by charging their vehicles directly at the charging station / charging pile and pay on-site to complete the transaction. When the electric vehicle's battery is low on power, it needs to be recharged. The main function of the charging station is to replenish the electric vehicle's battery power.

[0003] Existing patent CN202121547131.3 provides a replaceable power supply type mobile charging box, including a mobile box frame, a power supply, an inverter, a control device, and a heat dissipation device. The power supply is detachably mounted on the mobile box frame, while the inverter, control device, and heat dissipation device are fixedly mounted on the mobile box frame. The power supply is connected to the inverter, and the inverter is connected to the control device. This utility model, by setting a detachable power supply on a mobile box frame and providing a corresponding inverter and control device, enables the supply of power to various power tools on the construction site, and can provide a large amount of power for a long time. It has the advantages of simple overall structure, flexible mobility, convenient use, stability and reliability, and high safety factor.

[0004] However, the above-mentioned patent also has the following defects: the power supply on the above-mentioned mobile charging box is directly and detachably installed on the mobile box frame, which means that the inverter and control device installed on it are easily subject to external physical damage and pollution, such as impact and scratch, which may lead to component damage or performance degradation; in addition, it does not have dustproof and waterproof functions, and dust and moisture will cause internal components to age faster, reduce service life, and result in low durability.

[0005] While the presence or absence of a protective cover does not directly affect the ease of operation of the charging case, a well-designed protective cover can provide additional support and protection, making the charging case more stable and safer during movement and use.

[0006] In conclusion, the lack of a comprehensive protective cover may result in certain deficiencies in the safety, durability, maintainability, and operability of this type of power-swap portable charging box. Therefore, in practical applications, it may be necessary to consider adding a protective cover or other protective measures to improve the overall performance and safety of the charging box.
