Problems solved by technology
[0003] In the current terminal equipment, single-cell batteries are mainly used for charging. A conventional single-cell battery includes a set of pole pieces, a set of tabs and a battery connector. When the battery is fully charged, the voltage is around 4.5V. When the charging current exceeds 8A, the battery connector will heat up seriously. In order to meet the heat dissipation requirements, the charging power of the battery terminal of the usual single cell is about 36W, resulting in low charging efficiency.

The invention relates to a charging and discharging control framework, a charging and discharging control method thereof and terminal equipment. The charging and discharging control framework comprises a charging and discharging circuit and a double-cell battery. In the double-cell battery, a first battery connector is connected with a first positive plate through a first positive tab, a second battery connector is connected with a second positive plate through a second positive tab, and the input ends of the two battery connectors are both connected with the output end of the charging and discharging circuit; and in the charging and discharging circuit, a second charge pump module and a voltage reduction module are connected in series and then are connected to the input end and the output end of the charging and discharging circuit, a first charge pump module is connected to the input end and the output end of the charging and discharging circuit, and a control module is used for controlling a step-down module and the second charge pump module to charge the double-cell battery in a trickle charging stage, a constant-voltage charging stage and a charging cut-off stage, and controlling the first charge pump module to charge the double-cell battery in a constant-current charging stage. The charging and discharging control framework can improve the charging efficiency.
Description
technical field [0001] The present disclosure relates to the technical field of battery charging, and in particular to a charging and discharging control framework, a charging and discharging control method thereof, and a terminal device. Background technique [0002] A rechargeable battery is a rechargeable battery with a limited number of charging times and can be used with a charger. By charging the battery, the battery can be reused, which is beneficial to meet the needs of economy and environmental protection. The charging process of a battery is the reverse process of its discharging process, specifically, the process of converting electrical energy into chemical energy stored in the battery. [0003] In the current terminal equipment, single-cell batteries are mainly used for charging. A conventional single-cell battery includes a set of pole pieces, a set of tabs and a battery connector. When the battery is fully charged, the voltage is around 4.5V. When the chargi...
