Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] see figure 1 , figure 1 It is a structural diagram of an embodiment of a control system for charging a battery in the present invention, the control system includes a charging circuit 11 and a control circuit 12 .

[0024] The charging circuit 11 is used to charge the battery with a constant current at least part of the time.

[0025] Wherein, the battery may be a battery of any device capable of charging or discharging, such as a battery of a mobile phone, a computer, or an electric vehicle, and the like.

[0026] The control circuit 12 is coupled to the charging circuit 11, and is used for pulse charging the battery with an actual charging current greater than the specified current of the charger after the constant current charging is completed.

[0027] Please combine figure 2 , wherein, the charger specification current refers to the c...

Abstract

The invention discloses a control system, mobile terminal and control method for battery charging. The control system for battery charging includes a charge circuit and a control circuit, wherein the charge circuit is used for constant-current charge of a battery at least within part of time, and the control circuit is coupled with the constant-current charge circuit and is used for providing actual charge current larger than rated current of a charger for the battery for pulse charge after constant-current charge is completed. In this way, charge speed of the battery can be increased, and heat consumption for charge is reduced.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a control system for charging a battery, a mobile terminal and a control method. Background technique [0002] At present, the traditional lithium battery charging method in the industry basically adopts the constant current charging stage first, and then enters the constant voltage charging stage after the constant current charging stage is completed. [0003] In this charging method, the constant voltage charging time is relatively long, and the charging speed is relatively slow, especially for large batteries. That's because, when charging the battery, the voltage provided by the external circuit is divided into two parts: the first part is used to overcome the electromotive force of the lithium-ion battery itself, and the direction of this electromotive force is just opposite to that of the external circuit, and the second part is used to overcome the electromotive f...
