Abstract

The invention discloses a battery module for improving the charging rate and efficiency of terminal equipment and a working method of the battery modulethereof. The battery module comprises a batterypack composed of a plurality of identical batteries, a battery panel and an external interface. Power supply output management, charging management, electric quantity detection, battery switch controland charging and power supply path switching of the battery module are carried out through a the power supply management circuit on the battery panel. During early-stage high-voltage charging, the batteries are connected in series. T, the charging current of each battery is reduced , and the thermal power consumption of the battery is greatly reduced, so that the heating of the battery is reduced, the contradiction between quick charging and heating is solved, the charging speed of the battery module is increased, the user experience of the terminal equipment is improved, the battery module supports the output of various voltages, and the battery is more flexible to use.

Description

Technical field [0001] The present invention relates to electronic device charging technology, in particular to a battery module and its working method for improving the charging rate and efficiency of terminal devices. Background technique [0002] At present, the functions of terminal devices are becoming more and more abundant, and the requirements for battery capacity are getting higher and higher, so the requirements for charging speed of the terminal devices are becoming higher and higher, otherwise it will lead to too long charging time and seriously affect the user experience. [0003] The existing fast charging methods of terminal equipment basically adopt high-voltage charging, high-current direct charging, etc., but they all face serious charging and heating problems. Because the battery has a certain internal resistance, and the current that enters the battery during fast charging is relatively large, the power consumption of the internal resistance will also be relativ...

AI Technical Summary

Problems solved by technology

[0002] At present, the functions of terminal devices are becoming more and more abundant, and the demand for battery capacity is getting higher and higher, so the requirements for charging speed of terminal devices are also getting higher and higher, otherwise it will lead to long charging time and seriously affect the user experience

[0003] The existing fast charging methods for terminal equipment basically use high-voltage charging, high-current direct charging, etc., but they all face serious charging heating problems.

Because the battery has a certain internal resistance, and the current entering the battery during fast charging is relatively large, the power consumption consumed by the internal resistance will also be relatively large, resulting in low charging efficiency and rapid rise in battery temperature, which causes the device to heat up

In order to reduce the heating problem of the device, after charging the battery with a high current for a period of time, the charging current must be reduced to control the heating, resulting in a limited duration of fast charging, and the advantages of fast charging cannot be fully utilized

[0004] The output voltage of most batteries in the existing terminal equipment is between 3 and 5V, and the output voltage is single, only one voltage value can be output, and the application flexibility is not enough
