It is overheated that circuit processed exists, and charge control loop transships, and continues charging and charge circuit will be led to damage；If Tk≤Tkset and
OverFlag ≠ 1, then judge whether UsetFlag and IsetFlag is 1, if UsetFlag=1＆IsetFlag=1, presses
UsetFlag value is converted into first voltage outfan PMW1 output voltage, adjusts out maximum charge and limits voltage, then presses
IsetFlag value is converted into second voltage outfan PMW2 output voltage, adjusts out maximum charge and limits electric current, then marks charging
Will ChargeFlag puts 1, shows now super capacitor group to be charged, and temperature signal outfan T_ctl controls output to allow
Charge；Otherwise by clear for charge flag ChargeFlag 0, temperature signal outfan T_ctl controls output to disconnect charging circuit, forbids
Charge.
Refer to Fig. 1, Fig. 6, the control principle that wherein (6) state instruction controls is：The control running indication LED is by MCU
Run control signal be controlled, all put 1 when control logic detects UsetFlag and IsetFlag, illustrate to have read
Arrange parameter, now device be in running status, state instruction logic control Run signal makes operation LED light, otherwise extinguish fortune
Row LED.The flicker instruction of same charging indication LED, whether main judgement symbol ChargeFlag is 1；The sentencing of overheated indication LED
Breaking is whether foundation HotFlag is 1；Whether the indication LED of overload is 1 according to OverFlag.
The present embodiment is having the beneficial effects that of the control method of super capacitor module charge power supply：
1) it is directed to the charge requirement of super capacitor group, scalable setting charging voltage and charging current are it is adaptable to different hold
Amount and the super capacitor group of voltage request, adjustable charging current is adapted to need different to the different super capacitor group charging intervals
The occasion asked；
2) can automatic detection charge circuit whether transship, it is without damage to be automatically stopped charge protection charge circuit during overload,
Take into full account the situation that charging circuit may transship, overheated self-protection is provided, it is to avoid charging current is excessive or frequent charge is led
Charge circuit overload is caused to damage；
3) pass through to detect temperature and the temperature rise of super capacitor, and according to super capacitor temperature rise-current curve, charging is carried out
Current limliting, transfinites in super capacitor temperature rise simultaneously, stops charging when absolute temperature transfinites, charging process takes into account the temperature of super capacitor
Characteristic, carries out limiting using super capacitor temperature rise-current curve and charges, and simultaneously monitors that super capacitor temperature rise is too high and absolute temperature
Too high and stop charging, it is to avoid to continue charging and lead to temperature extremes to raise to cause the super capacitor life-span quick to reduce or occur quick-fried
Fried.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, some deformation can also be made and improve, these broadly fall into the protection model of the present invention
Enclose.
