Problems solved by technology

[0002] With the improvement of the performance of smart phones, their power consumption is also increasing. Correspondingly, it is necessary to provide a battery with a larger capacity, forming a technical problem that the charging time is getting longer and longer. The charging technology has improved the charging speed to a certain extent, but it still shows that the charging speed is not fast enough to meet the demand for charging with increasing battery capacity.

Abstract

The invention discloses a rapid charging control method, a device, a multi-cell battery and a mobile terminal, and relates to the technical field of rechargeable batteries. The rapid charging control method includes the steps: setting a parallel circuit among a plurality of cells in the multi-cell battery; coupling a switching circuit into the parallel circuit to form a series-parallel conversion circuit; connecting the series-parallel conversion circuit to an external interface of the multi-cell battery; receiving charging current by the external interface and converting the parallel circuit into a series circuit for charging by on-off state change of a plurality of electronic switches. The switching circuit is provided with the electronic switches. According to the technical scheme, on-off conditions of the electronic switches in the switching circuit can be adjusted according to charge-discharge conditions of the multi-cell battery, the series-parallel connection relationship among the cells of the battery is changed, the series charging and parallel discharging process can be at least realized, charging speed is improved, and better use experience is brought for users.

Description

technical field [0001] The invention relates to the technical field of rechargeable batteries, in particular, to a fast charging control method, a fast charging control system, a multi-cell battery and a mobile terminal. Background technique [0002] With the improvement of the performance of smart phones, their power consumption is also increasing. Correspondingly, it is necessary to provide a battery with a larger capacity, forming a technical problem that the charging time is getting longer and longer. The charging technology has improved the charging speed to a certain extent, but it still shows that the charging speed is not fast enough to meet the demand for charging with increasing battery capacity. [0003] Therefore, how to further increase the charging speed of a large-capacity battery with multiple cells has become an urgent technical problem to be solved. Contents of the invention [0004] The present invention aims to solve at least one of the technical probl...
