Wireless charging engineer Job Description 1 Qualifications: more than three years of wireless charger product development experience; Familiar with analog circuit, digital circuit and power circuit design; Skillful usepads20xx and other line and PCB drawing software; Understand the product development process; Work carefully, good communication skills; College degree or above, major in electronics.
In the test for the upcoming McGeek new energy disk, our engineers have carried out the maximum debugging of temperature control, power, continuity, etc., during the charging process, and strive to make the wireless charging experience the best. Chen Jinqiao, deputy chief engineer of the Telecom Research Institute of the Ministry of Industry and Information Technology, said that the traditional mobile phone charger (direct charge) is a standard, and wireless charging as an emerging technology, the country should be made as soon as possibleSet mandatory industry standards, so that consumers are informed and reference to use, this is the next step to carry out work. The lack of standards within the tolerance range of harm has made the market popular wireless chargers drill a "hole".
Wireless charging technology was invented by Nikola Tesla. In 1890, the physicist and electrical engineer NikolaTesla had already done experiments with wireless power transmission. The International System of Units for magnetic induction is also named after him.
electromagnetic induction. This is the more common way wireless chargers work, which uses the original electromagnetic inductionThrough the electromagnetic induction between the primary and secondary coils to generate current, so as to achieve the transfer of energy in the space; The implementation of this wireless charger has been promoted by the Wireless Charging Alliance.
Job Responsibilities of UI Designer 1 Responsibility Responsible for the design and creative work of website and mobile terminal software products; Set the overall visual style of the product (including interface, icon style and uniform specifications, etc.) and UI design; Participate in the formulation and specification of design experience and process; negativeResponsible for the inspection of vision realization, supervise the quality of product vision realization; Pay attention to user feedback and communication, and continuously optimize product UI based on analysis results.
The designer focuses on the customer and always understands the customer's requirements. Designers do a good job of communication and service with customers. The design scheme meets the function and practical value of decoration engineering as far as possible. The design scheme is reasonable and the material selection is appropriate. The design text is clear and clear, and should not be sloppy. Field measurements are accurate. The designer should make sure that the drawings have joint review and the construction site has design disclosure.
Establish and improve product interface visual design specifications. The rootControl chip, protocol chip.
Wireless charging function requires a wireless transmitting module and receiving module, now the new mobile phones launched by major mobile phone brands on the market have built-in wireless charging receiving module, some mobile phones without built-in receiving module need to be connected to an external receiving chip, the use of the receiving chip is also very simple (plug into the mobile phone charging port); The wireless charger needs to be connected to the power supply, but the phone can be placed on the wireless charger for wireless charging of the phone.
1, Zhirong 25W Super Fast charge 15W wireless fast charge mobile power scheme This scheme is based on Zhirong's latest super fast charge mobile power chip SW6208 and wireless charging chip SW5100 design and development, mobile power part continues the excellent performance of SW6208, One chip solves a variety of complex functions such as lifting voltage control, protocol recognition, 5 charging interface control, LED power display, etc. Its biggest feature is to support 25W super fast charge.
2, there is no big difference, that is, the charging current power is not the same, 25w fast charging faster than 15w fast charging. 2 Fast charge refers to a charging method that can make the battery reach or approach the state of full charge within 1 to 5h. It is often used for charging traction batteries when they need to be restored to a fully charged state in a relatively short time.
3, the difference between 15W and 25W is that the power is not the same, the charging speed is not the same, and the 25w fast charging is faster than the 15w fast charging. For example, in the case of mobile phone compatibility, the 15w charger is about 3000 MAThe battery takes about an hour, 25w charger, 3000 mah battery can be full in about 40 minutes.
4, in the pursuit of mobile phone fast charging and durable battery life of the era, I originally had little demand for mobile power. However, frequent work trips to the countryside forced me to consider carrying a reliable power bank. Among the many options, I chose WOPOW's innovative container design charging bank, which not only has a 25W&PD20W super fast charge, but also performs well in terms of appearance and practicality. The battery pack is simple and goes directly into the product itself.
5, w is super fast charge. Charging treasure 25w represents the power output of the charging treasure, and 25w is generally the normal value that can be achieved by fast charging. The basic charger outputs 5V/1A equal to 5W of power, and anything faster than that is considered fast or ultra-fast charging. The fast-charging space is still very fragmented, with almost every manufacturer having their own solution, and they don't share technology with each other.
