Fig. 2 showsbuck converter 26, this buck converter comprises two two utmost point junction transistors (BJT) 28 and 30 and when theinductor 32 ofpower conversion module 11 stored energy during withbuck converter 26 electrical communication, and it emits this energy as electric current duringpower conversion module 11 andbuck converter 26 electricalisolation.Buck converter 26 shown in Fig. 2 also comprises thecapacitor 34 that also is used as energy storage elements and also plays the effect of minimizing mains ripple.
The energy that is transferred tobattery 12 frompower conversion module 11 is controlled by the voltage levvl that control is applied ontransistor battery 12 from the energy ofpower conversion module 11, the actuation electrical signals of the terminal 14c (being designated as SW1) of self-controller 14 is applied on the base stage oftransistor 28 in the future, causes electric current to flow totransistor 28 and flow tobattery 12 frompower conversion module 11.
During actuated signal on removing the base stage that is applied totransistor 28, stop from the electric current ofpower conversion module 11, andinductor 32 is by the energy supply of current that is stored in wherein.Attransistor 28 off periods,terminal 14d (being designated as SW2) bycontroller 14 is applied to second actuated signal on the base stage oftransistor 30, so that can flow throughbattery 12 from the electric current of inductor (utilizingtransistor 28 duration of works to be stored in energy ininductor 32 and/or the capacitor 34).
During transistorized the opening or work period since 0% work period upwards climb, simultaneously controller or feedback loop are measured output current and voltage.In case reach determined charging current, feedback control loop utilizes the loop circuit linear feedback scheme for example to adopt ratio difference or PID mechanism to manage transistor.In case charger voltage output or battery terminal voltage reach alternating voltage, can adopt similar controlling organization to come the work period of oxide-semiconductor control transistors.
Therefore, at the electric current that is provided bypower conversion module 11 during the cycle of opening oftransistor 28 with at the effective current that wheninductor 32 discharges, causes being substantially equal to required charging current during the transistorized disconnected cycle by the electric current that it provided.Controller 14 periodically receives (for example, per 0.1 second) for example by at the measured value of the measuredbattery 12 of flowing through of thecurrent sensor 38 at battery terminal place and/or by the measured voltage at the battery terminal place of voltage sensor 36.According to this measurement electric current and/or measuring voltage that receives, the work periods regulated bycontroller 14 so that the electric current adjustment of thebattery 12 of flowing through, and this electric current is aggregated to the numerical value that is substantially equal to bycontroller 14 determined charging current levels like this.Thereforebuck converter 26 is configured to cause adjustable levels of current to be supplied tobattery 12 along with the adjustable duty cycle operation.
As mentioned above, additional sensor can be connected on thebattery 12 to exchange corresponding signal with controller 14.For example, temperature sensor (for example thermistor) can be connected to measuring of battery temperature is provided on the battery 12.Thermistor can be the outside of battery or in the inside of battery 12.Represent the signal of battery temperature to locate controlleddevice 14 receptions at one ofdirector port.Controller 14 is determined the temperature of battery by the signal that is received, and according to determined temperature, and controller is determined any follow-up action that will carry out.For example, the battery temperature that records can be compared with the temperature value in being stored in controller 14.If the temperature that records exceeds the permissive temperature scope, thencontroller 14 can prevent the beginning of charging operations, if charging operations begins, then stops charging operations, perhaps reduces charging current and or voltage according to circumstances.In some embodiments,charger 10 does not utilize heat monitoring and/or thermal control mechanism.
For determining the charging current tobattery 12 to be applied,controller 14 receives from being connected respectively on thebattery 12 and being configured to measure the voltage of crossing overbattery 12 terminals and thevoltage sensor 36 of the electric current of the rechargeable battery of flowing through and the voltage and current measured value of current sensor 38.In some embodiments, the electric current thatcharger 10 can make specified level (for example, be equivalent to 4 to 5C charged, wherein 1C in 1 hour to the rechargeable battery needed electric current that charges) be applied to the terminal ofbattery 12, therefore cause the specific voltage drop at the terminal place of battery, it depends on the resistance of battery.The voltage that thesenses VSENSE terminal 14b of controlleddevice 14 subsequently receives.
In some embodiments, employing can comprise that for example special-purpose charge controller device of analog logic treatment element (not shown) of threshold value comparator for example handles the input signal that received to determinetransducer 36 and/or 38 measured voltage and current levels.
According to those signals that receive from voltage andcurrent transducer controller 14 by the calculated signals that records by those for example the stable state of battery 12 (or direct current) charging resistor determine to be applied to the charging current level of terminal ofbattery 12 to give battery recharge.
Specifically,controller 14 makes first measuring current input I constantly first1Be applied in.The levels of current I that response is applied1, between the terminal ofbattery 12, produce voltage V1Controller 14 makes the electric current I that flows inbattery 121Keep special time period, therefore makebattery 12 can reach the charging stable state.In some embodiments, allowing the electrochemical cell of battery carry out the transition to needed total time of stable state charged state section by open-circuit condition is 30 to 60 seconds.(for example, make electric current I at moment place subsequently at controller1After being applied on thebattery 12 60 seconds), controller makes another levels of current I2Be applied on thebattery 12, therefore between the terminal ofbattery 12, produce voltage V2In some embodiments, first levels of current that is applied can be the levels of current that is equivalent to 4C (that is, battery was charged in 15 minutes, if battery has 1A hour capacity like this, the 4C charge rate is equivalent to the 4A electric current, and can be with the second levels of current I2Be set to the level (that is, with the levels of current that battery was charged) that is equivalent to 5C in 12 minutes.
For example, obtained and the corresponding measuring voltage of the levels of current that is applied, the difference between the closed circuit voltage that controller 14 records by calculating is determined the charging resistor of battery divided by the difference of applying electric current, that is:
Because second voltage is to measure after time period of stable state (the being non-transient state) resistance value that obtainedbattery 12 therein, the charging resistor that records is called stable state or DC charging resistor sometimes.
In some embodiments, can measure with other characteristic of treatment ofbattery 12 determining to be connected to the identity and the character of the battery on thecharger 10, and therefore determine to be applied to the charging current that recharges to it on the battery.
In some embodiments, specific battery types can be associated with a plurality of records in the look-up table, and each record is all corresponding with different charge rates.For example, charging current can be specified in a record related with particular type of battery, and it can obtain to equal about 90% charge level of battery capacity in about 5 minutes for battery.Can specify charging current with related another record of same battery types corresponding to different charge rates, for example will be in one (1) hour to battery recharge to full substantially battery capacity.Select suitable record for example to specify input according to the user who adopts the user interface (not shown) to offercharger 10 from a plurality of look-up table records relevant with concrete battery, user interface comprises switch, button and/or the knob that for example is arranged on the charger body.
Controller can be configured to also determine that the concrete charge level ofbattery 12 is to determine the charge parameter (for example, charging current and charging interval) tobattery 12 to be applied.For example, controller can make the voltage that sequence of current levels is applied in and measures to be provided between the terminal of battery.The contact potential series that utilization records can be determined the battery types and the charge level (according to the volume percent of battery) of this battery.In addition, also can determine the charging interval that wherein selected charging current must apply.
In some embodiments, the charge level ofdetermined battery 12 can be used in a plurality of records of selection in the look-up table related with determined battery types.For example, if the charging interval that will wherein charging current be applied on thebattery 12 is defined as 5 minutes, anddefinite battery charge 50% then can be selected first charging current from reaching battery recharge in 5 minutes of regulation near 100% look-up table that is full of.On the other hand, ifbattery 12 is only charged 20%, then can from look-up table, select higher charging current to be full of in 5 minutes of regulation, to reach near 100%.
In some embodiments, being used for can be based on the charge level of determinedbattery 12 to the charging interval and/or the charge rate ofbattery 12 chargings.For example, if determined thatbattery 12 is charged 50%, the then determined charging interval can makebattery 12 be charged to for example at least 90% charge level less than 5 minutes in (for example, 3 minutes).
As mentioned above, in case reach the pre-determined upper voltage limit (that is, alternating voltage) of about substantial constant,charger 10 can be therein it the voltage between the terminal ofbattery 12 is remained under the pattern of this upper limit and moves.Specifically, whenbattery 12 usefulness during basically according to the determined charging current for charging of charging resistor of battery, the voltage between the terminal of battery increases.For the voltage between the terminal of guaranteeing battery is no more than predetermined upper voltage limit (so that battery is not overheated, perhaps the work of battery or life expectancy can not be subjected to negative effect), the voltage that adoptstransducer 36 periodically to measure between the terminal of (for example, per 0.1 second)battery 12 has reached predetermined upper voltage limit to determine when.When the voltage between the terminal ofbattery 12 had reached predetermined upper voltage limit, the current/voltage regulating circuit controls so that the voltage between the terminal ofbattery 12 constant substantially (device of carrying out a kind of like this behavior is known as constant current/constant voltage or CC/CV device sometimes).
In some embodiments,controller 14 also can be configured to by the voltage between the terminal of periodically measuringbattery 12 and adjust the charging current monitoring voltage be applied on thebattery 12 and advances the speed, and makes voltage in a certain regulation raise and reaches predetermined upper voltage limit in the time period.Advance the speed according to the voltage that records, adjust the charging current level and increase or reduce charging current, make in the voltage rising time of regulation, to reach predetermined upper voltage limit.For example, adjusting the charging current level can carry out according to the prediction-alignment technique that adopts the Kalman filter.Specifically, the Kalman filter adopts the next numerical value according to the last measured value recurrence forecast system that excites or import of system responses of internal state of dynamical system.The Kalman wave filter technology can illustrate measured value deviation and the deviation in prediction (modeling) system responses.Therefore, when work, predicting the outcome of system is used for recursively proofreading and correct new response measurement value according to the prediction and the actual measured value of front at least in part.Therefore the Kalman filter can try hard to minimize the error between prognoses system response and the actual measured response.Can adopt and be used for determining to adjust other technology that electric current obtains predetermined upper voltage limit.
Fig. 4 describes an exemplary of thecharge step 50 that recharges to rechargeable battery 12.Randomly, in the charging compartments thatbattery 12 is injectedchargers 10 so that after the charging terminal ofcharger 10 was electrically coupled to the terminal ofbattery 12,controller 14 was measured the open circuit temperature and the voltage (52) of the battery unit of batteries 12.Controller 14 definite temperature T that record at first0With voltage V0Whether be in (54) between the predetermined bound, as defined in the memory module of the processor baseddevices 16 that is used for controller 14.Determined that therein this does not cause charging under the situation of operating under the unsafe condition of precondition in predetermined tolerance band internal cause for the initial temperature that records and voltage, charger does not continue charging operations, andstep 50 stops.
If determined the temperature T that records at first0With voltage V0Between predetermined bound, thencontroller 14 independently constantly makes two levels of current I at two1And I2Be applied to (56) on thebattery 12 to help measuring and/or at least one electrical characteristics (for example, battery terminal voltage) of counting cell 12.At least one measured electrical characteristics or indication itself are connected to the battery types on thecharger 10 or can determine to determine the characteristic derived (for example, stable state charging resistor) of the charging current tobattery 12 to be applied.Determine in the embodiment of charging resistor according to measured voltage that thereincontroller 14 is determined and the electric current I that applies1And I2Corresponding each voltage V1And V2Can measure the electrical characteristics (for example, with the corresponding measurement electric current of applied voltage) of other type.
Measured voltage V1And V2, then can determine following (58) withbattery 12 corresponding charging resistors:
The charging resistor of calculating is used for determining to be applied to the charging current (60) on thebattery 12, for example is stored in the look-up table retrieval and the corresponding charging current of calculating of charging resistor of memory stores module by visit.For the battery types that is associated with a plurality of charging current records, can adopt the user-defined target charging interval to select and the related suitable record of discerning by the battery behavior that records and/or calculate of battery types.In addition and/or alternatively, can adopt other technology (for example, computing technique) to determine charging current.
Randomly, determine that the concrete charge level (62) ofcontinuous battery 12 is to calculate the charge parameter (for example, charging current and charging interval) tobattery 12 to be applied.As mentioned above, by for example making sequence of current levels be applied on thebattery 12 and measuring between the terminal of battery under each gained voltage condition, can determine battery charge level therein.According to determined charge level and battery types, can determine charge parameter (for example, charging current and charging interval).
Determined charging current and the charging interval randomly tobattery 12 to be applied, the current/voltage regulating circuit shown in the control chart 2 for example buck converter 26 (64) so that provide constant electric current torechargeable battery 12 from the voltage of power conversion module 11.As mentioned above, handling the charging current level value that calculates in 60 places is applied on thebattery 12 electric current that is substantially equal to charging current to generate working period signal.Therefore, the output signal of controller is applied on thetransistor 28 ofbuck converter 26 for example so that be applied on thebattery 12 from the voltage of power conversion module 11.At the off period of particular duty cycle,power conversion module 11 disconnects withbattery 12, and the energy discharge that is stored ininductor 32 and/or thecapacitor 34 becomes electric current to battery.Electric current that is applied bypower conversion module 11 and the common effective current that is substantially equal to charging current that produces of electric current of emitting by inductor 32 (and/or capacitor 34).
When the current charges ofbattery 12 usefulness substantial constant, the voltage between the terminal of battery increases.For the voltage between the terminal of guaranteeing battery is no more than predetermined upper voltage limit (alternating voltage), periodically voltage has reached predetermined upper voltage limit (66) to determine when between the terminal of measurement (for example, per 0.1 second) battery 12.When the voltage between the terminal ofbattery 12 had reached predetermined upper voltage limit, Control current/voltage regulator circuit (startingtransistor power conversion module 11 applies the constant voltage of voltage levvl between the terminal that causesbattery 12.
Randomly, periodically measuring voltage is advanced the speed (68) to reach predetermined upper voltage limit in the voltage of stipulating raises the period.Advance the speed according to the voltage that records, adjust charging current level (corresponding adjustment is applied to the actual signal on the current/voltage regulating circuit) and in the voltage rising time of regulation, reach predetermined upper voltage limit to increase or to reduce charging current, to make.As described herein, can according to prediction-alignment technique for example other similar approach of Kalman filter or some carry out the adjustment of charging current levels.
In a period of time that is substantially equal to the regulation charging interval over and done with after, as 70 determined, termination is applied to the charging current (for example, starting so that the energy of being sent bypower conversion module 11 is terminated by the electricity that stops transistor 28) on the battery 12.Stop charge step when after the pre-determined upper voltage limit ofbattery 12 has reached or after the regulation charge level ofbattery 12 has reached, expiring.
