Machine is also connect with the temperature sensor being arranged outside lithium-sulfur cell, and the booster circuit and the reduction voltage circuit are DC-DC
Conversion circuit.
Preferably, further include display screen, connect with the AD converter.
Preferably, the model STM32 of the microcontroller.
Compared with prior art, the beneficial effects of the utility model are：It is fast to control speed, accuracy of detection is high, effectively
Management of charging and discharging is carried out to lithium-sulfur cell, has been filled up in the market without the blank suitable for lithium-sulfur cell charge and discharge control.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is a kind of schematic diagram of the charge and discharge control plate of lithium-sulfur cell of the utility model.
Meaning in figure represented by each symbol is as follows：
1- microcontrollers；2- booster circuits；3- reduction voltage circuits；4- temperature sensors；5-MOS is managed；6- display screens.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, the charge and discharge control plate of the utility model lithium-sulfur cell, includes mainly：The microcontroller of sequential series

Plate, its shape can be designed to different geomeries according to actual demand.In the loop also in parallel for connecting
The charging interface of external power supply and electric discharge interface for connecting external electric appliance.Wherein, booster circuit 2 and reduction voltage circuit 3 are
DC-DC conversion circuits.There is AD converter, to carry out sample detecting to voltage and current in microcontroller 1.Therefore, microcontroller 1 is gone back
It is provided with the charge cutoff voltage value and discharge cut-off voltage value of setting.In the present embodiment, the model of the microcontroller 1 of use
STM32。
When charging interface connects external power supply, and the voltage of lithium-sulfur cell is more than the charge cutoff voltage of setting, monolithic
Machine 1 controls metal-oxide-semiconductor 5 and turns off, to cut off charge circuit.And if the normal voltage of battery is 4.9V, charging voltage 5V, it rises
The effect of volt circuit 2 is exactly that charging voltage is amplified to 6V or so, to ensure that battery can smoothly charge.Reduction voltage circuit 3
Effect is similarly.When electric discharge interface connects external electric appliance, and the cell voltage of lithium-sulfur cell is less than the discharge cut-off voltage set,
Microcontroller 1 controls metal-oxide-semiconductor 5 and turns off, to cut off charge circuit.When current detecting to battery short circuit or entire loop current are excessively high
When more than setting value, the control electric discharge metal-oxide-semiconductor 5 of microcontroller 1 turns off, and plays short circuit and overcurrent protection function.
Microcontroller 1 is also connect with the temperature sensor 4 being arranged outside lithium-sulfur cell.The probe of temperature sensor 4 is linked at
Near outside batteries, for detecting the temperature range of battery.When detecting battery supercooling or overheat, the control of microcontroller 1 is cut
Disconnected electrical circuit plays the role of protecting battery.
The AD converter of microcontroller 1 is also connect with display screen 6, so that the electricity that display screen 6 can be detected with real-time display
Cell voltage and electric current.
To sum up, the utility model is with STM32 microcontrollers 1 for core controller, control booster circuit 2, reduction voltage circuit 3
The charging voltage of battery is provided, and microcontroller 1 also controls and acquires monitoring lithium sulphur in real time using the AD converter of Embedded
