Embodiment approach 1

[0088] Optionally, in some embodiments, the two-way communication between the control unit 71 and the adapter through the data line to control the charging process of the multi-cell battery 13 may include: the two-way communication between the control unit 71 and the adapter to determine the charging mode; When it is determined to use the fast charging mode to charge the terminal, the control unit 71 controls the adapter to charge the multi-cell battery 13 through the first charging circuit 12; The second charging circuit 61 charges the multiple batteries 13 .

[0089] In the embodiment of the present invention, the terminal does not blindly perform fast charging through the first charging circuit, but conducts two-way communication with the adapter to negotiate whether the fast charging mode can be used, which can improve the safety of the fast charging process.

[0090] For example, the two-way communication between the control unit 71 and the adapter to determine the chargi...

Embodiment approach 2

[0092] Optionally, in some embodiments, the two-way communication between the control unit 71 and the adapter through the data line to control the charging process of the multi-cell battery 13 may include: the two-way communication between the control unit 71 and the adapter to determine the fast charging mode. Charging voltage.

[0093]For example, the two-way communication between the control unit 71 and the adapter to determine the charging voltage in the fast charging mode may include: the control unit 71 receives a second instruction sent by the adapter, and the second instruction is used to inquire whether the current output voltage of the adapter is suitable for fast charging. The charging voltage of the mode; the control unit 71 sends a reply command of the second command to the adapter, and the reply command of the second command is used to indicate that the current voltage is suitable, high or low. Optionally, the second command is used to inquire whether the current...

Embodiment approach 3

[0095] Optionally, in some embodiments, the two-way communication between the control unit 71 and the adapter through the data line to control the charging process of the multi-cell battery 13 may include: the two-way communication between the control unit 71 and the adapter to determine the fast charging mode. recharging current.

[0096] For example, the two-way communication between the control unit 71 and the adapter to determine the charging current in the fast charging mode may include: the control unit 71 receives a third instruction sent by the adapter, and the third instruction is used to inquire about the maximum charging current currently supported by the terminal; the control unit 71 Sending a reply command of the third command to the adapter, the reply command of the third command is used to indicate the maximum charging current currently supported by the terminal, so that the adapter determines the charging current of the fast charging mode based on the maximum ch...

Abstract

An embodiment of the present invention provides a terminal, the terminal includes: a charging interface; a first charging circuit, connected to the charging interface, used to receive the output voltage of the adapter through the charging interface, and directly load the output voltage of the adapter on the mutual The two ends of the multiple battery cells connected in series charge the multiple battery cells. The embodiment of the present invention can reduce the calorific value of the charging process under the premise of ensuring the charging speed.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic equipment, and more specifically, relate to a terminal and equipment. Background technique [0002] At present, mobile terminals (such as smart phones) are more and more favored by consumers, but the mobile terminals consume a lot of power and need to be charged frequently. [0003] In order to increase the charging speed, a feasible solution is to use a large current to charge the mobile terminal. The larger the charging current, the faster the charging speed of the mobile terminal, but the more serious the heating problem of the mobile terminal. [0004] Therefore, how to reduce the heating of the mobile terminal under the premise of ensuring the charging speed is an urgent problem to be solved at present. Contents of the invention [0005] An embodiment of the present invention provides a terminal, which can reduce the calorific value of the terminal under the premise of ensu...
