Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , The power supply device 100 according to the preferred embodiment of the present invention includes a controller 10 , a switch module 30 , a battery pack 50 composed of a plurality of batteries 51 and an output terminal 70 . The plurality of batteries 51 are connected in series and connected to the output terminal 70 through the switch module 30, and the switch module 30 is connected to the controller 10, and is turned on or off under the control of the controller 10. ON, so that a certain number of batteries 51 output a preset power supply voltage to the load (not shown) through the output terminal 70 . In addition, when the controller 10 detects that the power supply device 100 is in an overvoltage state, it disconnects the switch module 30 to stop the battery pack 50 from outputting electric energy.

Abstract

A power supply device comprises a battery pack, a controller, a switch module and an output end. The battery pack can output preset power supply voltage to a load through the output end and comprises a plurality of batteries which are connected in series and connected with the output end through the switch module. The controller is connected to the output end and the switch module to detect voltage outputted by the battery pack. The controller first sequentially controls each battery to output the preset power supply voltage individually, then sequentially controls two or more than two batteries to be connected in series and enables the total voltage outputted by the plurality of batteries connected in series to reach the preset power supply voltage until the total voltage of all the batteries sequentially connected in series is still lower than the preset power supply voltage when the voltage outputted by each battery is detected to be lower than the preset power supply voltage.

Description

technical field [0001] The invention relates to a power supply device, in particular to a direct current power supply device. Background technique [0002] Most of the built-in power supplies of commonly used electronic devices are DC power supplies, and when they release electric energy to supply power to electronic devices, the voltage of the power supply will generally decrease continuously with the decrease of its own power. Once the supply voltage of the DC power supply drops below the normal start-up voltage of the electronic device, the DC power supply needs to be recharged before it can supply power to the electronic device. At this time, although a certain amount of electric energy is still stored inside the DC power supply, this portion of electric energy cannot be utilized by the electronic device before charging. Apparently, the above-mentioned design method easily leads to low utilization rate of the DC power supply and frequent charging. Contents of the inve...
