It is reported that Apple plans to use laminated battery technology on the iPhone 15 series, which can reduce heat generation, improve the charging speed and battery life of the device, and provide more usable power at the same time. Today Aigtek will give you a brief introduction to this technology.
With this stacked battery technology, the iPhone 15 series can charge the battery faster, with a maximum power of 40W, and the battery is more durable, which can be said to be a huge improvement. It is said that Samsung's next-generation regular flagship will also adopt this battery technology.
Laminated battery technology, in fact, has the same properties as ordinary batteries, but its output voltage depends on the number of laminated batteries. When 6 dry batteries are used in series, the total voltage of laminated batteries is 9V, which can help laminated batteries have Smaller size, higher output voltage, but its output current is small, it is not suitable for use as a high-power electrical equipment, but only suitable for portable instruments.
In addition to stacked battery technology, what other new charging technologies have entered our lives now? That is the wireless power transmission technology. Let me introduce its principle and the application of power amplifiers in it~
Principles of wireless power transfer technology
According to the different forms of relay energy in the energy transmission process, wireless power transmission technology can be divided into magnetic (field) coupling, electric (field) coupling, electromagnetic radiation (such as solar radiation), mechanical wave coupling (ultrasound), etc. Among them, the magnetic coupling type is a power transmission system based on the principle of electromagnetic induction. It is the most popular wireless power transmission method in the early 21st century. Under the excitation, a high-frequency magnetic field is generated, and the receiving coil is coupled to generate a current under the action of this high-frequency magnetic field to realize wireless energy transmission.
Application of wireless power transfer technology
Wireless power transmission technology is widely used in the current field of application. It has several advantages such as non-contact, fully sealed, convenient, automatic, and can solve problems that cannot be solved by wired. It is used in new energy vehicles, electric vehicles, portable electronic products, and household appliances. Micro power applications, robots/UAVs, underwater applications, special applications and other fields have good applications.
Aiming at the high-power driving problems involved in this technology, ATA-3040 power amplifier gives the answer. This high-power power amplifier has a maximum output power of 360Wp, a current of 8Ap, and a bandwidth of DC~100kHz. Power type load, the gain voltage is adjustable by numerical control, equipped with a program control interface, which can realize remote operation.
