The utility model content
The purpose of the utility model is to provide a kind of charging device that has charging control unit, can be implemented in the charging process temperature, charging voltage and electric current are monitored in real time; Battery to the needs charging charges safely and effectively.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of charging device with charging control unit comprises the charging device shell, is arranged at the display unit of housing, the power input end mouth, and be arranged at the mainboard in the shell, said mainboard is integrated with the alternating current-direct current potential device, MCU and charging circuit; Described mainboard also is integrated with charging control unit, and said charging control unit is connected with the MCU circuit; Said charging control unit comprises the charging time control circuit, TEMP module, and voltage and current sense module.
Preferably: described power input end mouth is a plug or USB interface.
More preferably: described display unit is the LED lamp of difference green light and ruddiness.
More preferably: described display unit is the LED display curtain.
The utility model compared with prior art has following advantage and beneficial effect:
The utility model is through being provided with charging control unit in charging device, said charging control unit is connected with the MCU circuit; Said charging control unit comprises the charging time control circuit, TEMP module, and voltage and current sense module.Can realize that to charging voltage and electric current, the temperature of battery is monitored in real time during charging,, select constant current or constant voltage charge automatically according to the control of timing circuit; Thereby reduced the problem that battery possibly occur to greatest extent in charging process; Reach extending battery life and prevent the purpose that battery damages.
Description of drawings
Shown in Figure 1 is the structured flowchart of the said charger of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
Be illustrated in figure 1 as the structured flowchart of the charger of the said band charging control unit of present embodiment; Described charging device comprises the charging device shell, is arranged at the display unit of housing, the power input end mouth, and be arranged at the mainboard in the shell, said mainboard is integrated with the alternating current-direct current potential device, MCU (microprocessor) 100 and charging circuit 300; Described mainboard also is integrated with charging control unit 200, and said charging control unit is connected with the MCU circuit; Said charging control unit comprises the charging time control circuit, TEMP module, and voltage and current sense module.
Described power input end mouth is a plug or USB interface.
Described display unit is the LED lamp of green light respectively (charging carry out in) and ruddiness (stopping to charge); For the higher charger of quality requirements, also can show in real time temperature, voltage or electric current through the LED display curtain.
When the charger of use present embodiment charges to battery; Charger is carried out circuit with plan rechargeable battery 500 to be connected; Charger passes through the electric current of power input end mouth input if alternating current; Then need pass through alternating current-direct current transformer 400 and convert interchange to direct current, and the charging voltage that voltage transformation is allowed to charger; Charging circuit effectively charges to intending rechargeable battery according to the instruction of MCU.In charging process, charging control unit is through the TEMP module, and voltage and current sense module in time monitor temperature, voltage and the electric current of the battery that is charging.When monitoring the temperature of intending rechargeable battery, charging control unit is lower than preset temperature (as 48 ℃); And cell voltage is during less than the predeterminated voltage value; Charging control unit is sent the instruction of charging to charging circuit through MCU; Drive charging circuit and continue charging, and signal lamp is shown as charged state (green light is bright) intending rechargeable battery; When charging control unit monitors voltage when reaching a certain other predetermined intermediate value, the instruction that charging control unit is sent constant current charge through MCU to charging circuit realizes that to intending rechargeable battery constant current fills soon; When monitoring voltage, charging control unit reaches a certain predetermined high value (like 4.4V; This moment is comparatively approaching apart from intending rechargeable battery setting voltage (4.5V)) time, the instruction that charging control unit is sent constant voltage charge through MCU to charging circuit realizes constant voltage charge to intending rechargeable battery; Make electric current reduce gradually; Through timing circuit monitor reach preset charged guard time (like 30min) after, charging control unit is sent the instruction that stops to charge through MCU to charging circuit, charging is accomplished; Be higher than preset temperature if charging control unit monitors the temperature of intending rechargeable battery, directly send the instruction that stops to charge to charging circuit, interrupt continuing charging through MCU.
The utility model is through being provided with charging control unit in charging device, said charging control unit is connected with the MCU circuit; Said charging control unit comprises the charging time control circuit, TEMP module, and voltage and current sense module.Can realize that to charging voltage and electric current, the temperature of battery is monitored in real time during charging,, select constant current or constant voltage charge automatically according to the control of timing circuit; Thereby reduced the problem that battery possibly occur to greatest extent in charging process; Reach extending battery life and prevent the purpose that battery damages.
