Example Embodiment

[0031] In order to solve the problems of heat generation and slow charging of the terminal in the prior art, the present invention provides a charger, a terminal and a charging method.

[0032] The invention can adopt a fast charging method between the charger and the terminal. The fast charging method avoids the use of the built-in charging chip of the terminal and instead uses the external charging chip in the charger, which reduces the current loss during the transmission process, thereby reducing the terminal The temperature during the charging process increases the output power of the circuit, thereby shortening the charging time of the terminal.

[0033] The present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but do not limit the present invention.

[0034] The invention provides a charger, such as figur...

Abstract

The invention discloses a charger, a terminal and a charging method. The charger comprises a transformer and an external charging chip, wherein the transformer is used for outputting a first electrical parameter to the external charging chip, and the external charging chip is used for transforming voltage of the first electrical parameter to obtain a second electrical parameter and outputting the second electrical parameter to a terminal to quickly charge the terminal. The terminal is matched with the charger in use. The terminal comprises a direct channel used for outputting the second electrical parameter input by the charger to a battery to quickly charge the battery. The problem that a terminal emits heat during charging and is low in charging speed is effectively solved. In the invention, when the circuits of the charger and the terminal are capable of fast charging, the charger directly inputs an electrical parameter required by the terminal to the terminal, which avoids the use of a charging chip built in the terminal, reduces the loss of current in the transmission process, improves the output power of the circuits and shortens the time for terminal charging.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charger, a terminal and a charging method. Background technique [0002] Existing mobile terminals, such as mobile phones, mostly use a USB (Universal Serial Bus, Universal Serial Bus) interface for charging. Such as figure 1 Shown is a schematic diagram of the existing charging principle. The existing charging principle is that the charger converts high-voltage alternating current into 5V direct current, and outputs it to the mobile phone through the USB interface. [0003] However, at present, the power consumption of mobile terminals is increasing, and the battery capacity is also increasing. The problems of charging heat and slow charging are very prominent. Furthermore, in the traditional charging method, it is difficult to increase the charging current. The main reason is that the current is continuously lost in the process from the output terminal of the charger t...
