Abstract
The utility model provides a lacunar depolarized amplitude pulse charging device comprising a/an charging power [AC/DC], [MCU], electronic switching circuit, etc. A voltage-regulating output head on the microprocessor is connected with the control circuit of the charging power [AC/DC]. The voltage control signal transmitted by the microprocessor could control the output voltage of charging power through the work of the control circuit of the charging power; on one hand, the charging of battery would be stopped if the output voltage of charging power is decreased lower than the charging voltage of battery and on the other hand, the charging of battery would be resumed otherwise; this method realizes the pulse charging of battery which could not only leave out one more electronic switching circuit but also cause tiny impact on the whole charging circuit to prolong the service life of charging device and decrease the cost and maintenance expense.
Description
Technical field the utility model relates to a kind of intermittence depolarising variable amplitude pulse charging device, is used for VRLA storage battery, MH-Ni storage battery, Li
+The charging of storage batterys such as storage battery.
Background technology is because of VRLA storage battery, MH-Ni storage battery, Li
+Storage battery progressively is applied to electric motor car, makes their use amount more and more big, is exactly the storage battery of these types as the storage battery of the configuration of the major part in the current commercially available electric bicycle.But the storage battery of these types because of the charge mode of normal charge device is unreasonable can aggravation storage battery combination in each monomer performance inconsistency cause useful life short, general only one year about.For remedying this defective, the applicant once designed a kind of intermittence depolarising variable amplitude pulse charging device (number of patent application: 200420014283.7): " and the charge power supply AC/DC that is made of high frequency switch power is arranged, between charge power supply and storage battery by a positive negative pulse stuffing generation circuit of forming with the electronic switch of microprocessor MCU control.The composition of said positive negative pulse stuffing generation circuit is: have an electronic switching circuit and storage battery to be connected on the charging circuit, other is in parallel with storage battery after having an electronic switching circuit and a load to connect, the control end of these two electronic switching circuits is connected with a microprocessor MCU signal output part respectively, has a signal input part to be connected with accumulator anode on the microprocessor." this charging device; under the control of microprocessor, begin storage battery to be charged; after being charged to a constant volume; change the periodic waveform electric current that alternately forms in succession with the charging pulse of intermittence and depolarising pulse into storage battery is charged; the ratio of also adjusting after being charged to a certain degree between the electric weight of the electric weight of charging pulse and depolarising pulse reduces with the increase of charging capacity, and each internal resistance of cell is reached unanimity with constant current.This charging device makes the life of storage battery and doubles than using the normal charge device.But in this design, used two electronic switching circuits, not only the electronic device of Shi Yonging is more and cause more fault point, and the break-make of charging current changes to the impact of circuit greatly, makes this charger have the possibility of bigger damage.
Summary of the invention is at above-mentioned deficiency, and the utility model will solve the technical problem of using two electronic switching circuits in the present technology, to propose the littler intermittence depolarising variable amplitude pulse charging device of a kind of probability of damage.
The intermittence depolarising variable amplitude pulse charging device that the utility model provides, the charge power supply AC/DC that is made of high frequency switch power is arranged, one microprocessor MCU is connected with charge power supply AC/DC control end with positive pulse generation control signal output ends, and one electronic switching circuit and load series connection back in parallel with storage battery, the control end of this electronic switching circuit is connected with microprocessor MCU negative pulse generation control signal output ends, there is a battery tension signal input part to be connected on the microprocessor, also has a pressure regulation signal output part to be connected on the control circuit of charge power supply AC/DC on the microprocessor with accumulator anode.
The intermittence depolarising variable amplitude pulse charging device that the utility model provides, said microprocessor MCU pressure regulation signal output part are on the pulse duration signal input end that is connected in the control circuit of charge power supply AC/DC.That is to say, pressure regulation signal that microprocessor is exported is to regulate the pulse duration that HF switch is wherein exported through the control circuit in the charge power supply to the charge power supply role, promptly regulate the output duty of ratio, thus the voltage of the positive pulse charging current that the adjusting charge power supply is exported.
The intermittence depolarising variable amplitude pulse charging device that the utility model provides, in circuit to be subjected to being connected of control circuit in microprocessor voltage control signal output and the charge power supply, make this technical scheme of output voltage of the work control charge power supply of voltage control signal control circuit in charge power supply that microprocessor exports substitute the electronic switch that is subjected to microprocessor control of the prior art, it is following and end the charging of storage battery and make the output voltage of charge power supply rise to the charging that recovers more than the charging voltage of storage battery storage battery that utilization makes the output voltage of charge power supply reduce to the charging voltage of storage battery, realizes the pulse current charge to storage battery.This control device to charging positive pulse electric current, the circuit that utilizes charge power supply self to be possessed not only, saved an electronic switching circuit, and the break-make of charging operations be charging current voltage charging voltage up and down variation rather than the variation of electric current through and off realize, impact to whole charging circuit is very little, thereby has improved the useful life of charging device and reduced its cost and maintenance cost.
