Describe the charging course of work of the utility model Based Intelligent Control charging device in detail below in conjunction with accompanying drawing.
● preliminary filling
After installing lithium battery, connect input 12V DC power supply, when charger detects battery, with the RST key timer is resetted, thereby enter the preliminary filling process, charger charges the battery with 10% of charging quickly stream during this period, makes lithium battery voltage, temperature return to normal condition.Pre-charging time is determined (being 45 minutes during 100nF) by the external capacitor C11 of MAX1898 chip the 4th pin.If lithium battery voltage reaches 2.5V in pre-charging time, and battery temperature is normal, and then charging enters the process of filling soon; If after surpassing pre-charging time, lithium battery voltage still is lower than 2.5V, thinks that then lithium battery is not chargeable, charger shows the lithium battery fault, the LED light flicker.
● fill soon
The process of filling is also referred to as constant current charge soon, this moment charger with constant current to lithium cell charging.During constant current charge, lithium battery voltage slowly rises, in case lithium battery voltage reaches the final voltage that sets, constant current charge stops, the fast quick depletion of charging current, and charging enters the process of completely filling.
● completely fill
Completely filling in the process, charging current decays gradually, drop to below the value of setting up to charge rate, or the time of completely filling is overtime, changes the top over to by charging.The top is when charging, and charger is the lithium battery makeup energy with minimum charging current.Because charger has charging current to pass through the internal resistance of cell when whether the detection cell voltage reaches final voltage, although descend gradually completely filling with top charging current in the charging process, reduced the influence of lithium battery internal resistance and other series resistances, but it is still influential to the detection of lithium battery final voltage to be connected on the pressure drop that the resistance in the charge circuit forms to the lithium battery terminal voltage.Generally speaking, completely fill the service time that can prolong lithium battery 5%～10% with the top by charging.
● outage
After lithium battery was full of, the impulse level that the 2nd pin CHG of MAX1898 chip sends can be uprised by low, and this will be detected by monolithic machine circuit 4, causes the interruption of single-chip microcomputer.In interruption, finish if judge charging, then single-chip microcomputer will cut off the power supply of LM7805 to MAX1898 by the 2nd foot control system optocoupler 6N137 in the AT89C52 chip, thereby guarantee the safety of chip and battery, also reduce power consumption simultaneously.
● report to the police
After lithium battery was full of, MAX1898 chip itself can extinguish external LED green light.But for the sake of security, single chip circuit 4 can cut off the power supply of MAX1898 chip automatically after the pulse that detects full state, and by buzzer warning, reminds the user in time to take out lithium battery.When charging makes mistakes, the frequency scintillation of MAX1898 chip control LED green light about itself with 1.5Hz, do not cut off the power supply of chip this moment, allow the user see this prompting.
