1、 Design

The design of the portable charging gun motherboard aims to provide greater power in a small size and minimize its volume as much as possible. Therefore, in the design, it is necessary to focus on its structure, materials, and manufacturing process. Structurally, while minimizing volume, it is also necessary to ensure strength and reliability to ensure its normal use. In terms of materials, it is necessary to consider their characteristics such as power density, thermal conductivity, and voltage resistance, in order to minimize the volume as much as possible while considering the quality and safety of the electric gun. In terms of manufacturing process, precision, surface treatment, and overall assembly should be considered to ensure that the final precision requirements can be met.

2、 Circuit

The circuit design of the portable charging gun motherboard should consider its electrical characteristics to ensure that it can charge normally. The circuit mainly includes modules such as power supply, control, regulation, and display. The power module should consider its input voltage, output current, voltage stability, etc; The control module mainly needs to consider its functional control, protection, etc; The regulation module should consider its regulation, current limiting, overheating protection, etc; The display module mainly needs to consider its display, alarm, etc.

3、 Security

The safety requirements of the portable charging gun motherboard are also very important, taking into account the safe use of the electric gun to ensure the safety of users. Mainly including waterproof protection, overcharge protection, overcurrent protection, overheating protection, etc. Waterproof protection can be encapsulated with sealing materials to prevent water vapor from entering; Overcharge protection can be achieved through circuit design to detect battery voltage and automatically disconnect the power supply; Overcurrent protection can be achieved through circuit design to detect the magnitude of current and automatically disconnect the power supply; Overheating protection can also be achieved through circuit design to detect temperature and automatically disconnect the power supply.

4、 Shell

The shell design of the portable charging gun motherboard should consider its appearance, shape, protection, etc. The appearance requirements should consider factors such as size, color, and material to meet the requirements of its design; The external requirements should consider its structure, size, weight, etc. to meet its portability needs; The protection requirements should consider arc protection, waterproof protection, etc. to ensure the safety of its normal use.

5、 Interface

The interface design of the portable charging gun motherboard is mainly to meet the needs of connecting peripheral devices such as batteries and chargers. On the interface, safety, reliability, and ease of wiring requirements should be considered. Special interfaces can be used to meet its connection requirements, or commonly used interfaces can be used to achieve ease of use.

6、 Testing

The testing of the portable charging gun motherboard should consider the reliability of its components, the correctness and stability of the circuit, the protection of the housing, the reliability of the interface, and the safety of the battery to ensure its normal operation. Electrical testing, environmental testing, vibration testing, safety testing, and other methods can be used during testing to ensure its normal use.
