A battery current management system for rapid discharge of battery packs is disclosed. The system consists of a voltage conversion circuit and multiple switch modules in parallel. When the battery current management system works in the discharge state, the voltage conversion circuit not only provides the main discharge current signal to discharge the battery pack, but also controls the switch modules. Supplementary discharge current is provided to discharge the battery pack. In addition, the battery current management system can also be set to work in the charging state. At this time, the voltage conversion circuit can provide the main charging current signal to charge the battery pack, and the voltage conversion circuit also controls the switch module to provide supplementary charging current to charge the battery pack. This solution improves the discharge and charge capability of the entire battery pack system, increasing efficiency and saving time.
Description
technical field [0001] The present invention relates to an electronic circuit, and more particularly, the present invention relates to a battery current management system. Background technique [0002] With the popular use of a large number of portable electronic products (such as tablet computers, phablets, notebook computers, ultra-thin computing devices, power banks, etc.), battery charge-discharge circuits are widely used in these portable devices. In these portable devices, the requirements for battery life are getting higher and higher, and the battery capacity is getting bigger and bigger. Therefore, manufacturers have higher requirements on the speed of battery charging, and need to provide a larger current to charge the battery to shorten the charging time. At the same time, in some applications, some portable devices are also required to supply power to other portable devices, and at the same time, it is also expected that the current capability of the external po...
