Abstract
A battery discharge current management system used for discharging battery packs. The battery discharge current management system has a voltage converting circuit and at least one switch module. The voltage converting circuit can operate at a charge mode or a discharge mode. The voltage converting circuit can serve to discharge battery packs so as to provide a master discharge current signal to other devices when it operates at the discharge mode. The voltage converting circuit further controls the at least one switch module to discharge the battery packs so as to provide at least one additional discharge current signal.
Claims30
A battery discharge current management system, comprising:
- a voltage converting circuit, having a first pin, a second pin, and a third pin;
- and
- a first switch module, having a first terminal coupled to the first pin, a second terminal coupled to the second pin, and a control terminal coupled to the third pin;
- and wherein
- when the battery discharge current management system is configured to operate in a discharge state, the voltage converting circuit is configured to convert a system voltage signal at the second pin to an output voltage signal at the first pin, and further configured to generate a master discharge current signal at the first pin, and further configured to control the first switch module to generate a first additional discharge current signal at the first terminal of the first switch module.
A battery discharge current management system, comprising:
- a voltage converting circuit, having a first pin coupled to a USB port, and a second pin coupled to a battery pack;
- a switch module, having a first terminal coupled to the first pin, a second terminal coupled to the second pin;
- and wherein
- the voltage converting circuit is configured to generate a master discharge current signal at the first pin when an output voltage signal is provided at the first pin, and further configured to control the switch module to generate an additional discharge current signal at the first terminal of the switch module.
A voltage converting integrated circuit, comprising:
- a first pin;
- a second pin;
- and
- a third pin, configured to provide a switch module control signal;
- wherein when an output voltage signal is provided at the first pin, the voltage converting circuit is configured to generate a master discharge current signal at the first pin, and the switch module control signal is configured to control the switch module to generate an additional discharge current signal at the first pin.
