Under normal circumstances, the service life of the charging bank is about 3 years. Under the premise of normal use, if it is a newly imported lithium battery, it is used 1 to 2 times a day, and after a year, the capacity of its battery will be reduced to about 80% of the original. If it is an ordinary lithium battery, then the decline in battery capacity is obvious after one year of use.
The life of the charging bank is generally 2-Three years. The life of the charging bank will be affected by many factors, the most direct factor is the life of the battery. Under the premise of normal use: if it is a new imported lithium battery cell, use it once a day, and use it for 2-3 years to ensure that the capacity is more than 80% of the initial capacity. If it is an ordinary lithium battery cell, then in general, there will be no significant capacity reduction for 1 year.
The increase in the use time of the charging treasure, the battery storage capacity will gradually weaken, according to relevant data show that the service life of the charging treasure is generally about 3 years. The battery inner core will be lost with the increase of charging times, and the service life of the charging treasure is mainly caused by chargingIt depends on the number of times. According to relevant data, the service life of the charging treasure is generally about 3 years. This is because the inner core of the battery inside the charging treasure will gradually lose over time.
Wireless charging emission Circuit board (PCBA) refers to an electronic component used to achieve wireless charging function, which mainly includes a circuit board (PCB) and various electronic components installed on the circuit board. These components togetherIt forms part of a complete wireless power transmission system, which is responsible for converting electrical energy into wireless signals and transmitting them to receiving devices. Wireless charging technology usually works on the principle of electromagnetic induction or magnetic resonance.
Dismantling reveals its precise construction: zinc alloy bracket provides solid support, the internal PCBA board integrates wireless controller and power chip, wireless charging control is at your fingertips, thanks to the powerful wireless charging chip Zhirong SW5001. The SW5001 chip is powered at 5V/50mA, has full built-in protection, and also has an I2C interface for flexible voltage division to 5V/9V/12V, to ensure efficient and stable device charging.
In response to the huge demand brought by the continuous hot TWS headset market, Fuhengtai released a special PCBA module for TWS wireless charging box with 5W receiving power, and the board does not change to support wireless charging, which minimizes the development cost of customers.
The PCBA board is green and is distributed in a ring shape around the central coil. Remove the PCBA. A piece of thermal foam is attached to the back of the panel. Wireless charging front, wireless charging coil in the middle, no components on the back of the circuit board. The front of the circuit board is a magnetic separator, and the circuit board is inverted. And a $1 coinCompare the size. Wireless charger all components. IDT P9237 wireless charging transmitter controller. Type-C interface sinking plate welding. External memory of IDT scheme.
Wireless charging integrated power level chip using Zhirong SW5001, is a highly integrated wireless charging transmitter integrated power level chip. Zhirong SW5001 has integrated 5V 50mA power supply output, which can supply power for wireless charging main control microcontroller, eliminating the power supply circuit of microcontroller. The SW5001 has integrated input overvoltage, input undervoltage, output short circuit and overheat protection.
Wireless chargingThe electric coil and temperature detection are integrated in the PCBA module, and the precise combination of graphite heat transfer tape, copper heat dissipation and double-sided tape ensures efficient heat dissipation of the battery and ensures stable performance under long-term use. In addition, the built-in five LED power indicator, so that the charging process is mastered. Precision design wireless charging part adopts Jiangxi Lianzhiji CWT1504M master control, with Gufeng G33N03D3 power tube, further improve the efficiency of wireless charging.
