Description
Technical field
The utility model belongs to charger technical field field, and what relate generally to is a kind of intelligent battery charger.Charge in batteries adaptable across motor vehicles such as all kinds of charge in batteries use, especially electric motor cars uses.
Technical background
Traditional all kinds of electromobile battery chargers, what in battery charging process, realized only is that storage battery is carried out electric weight.Owing to do not have relevant detection and defencive function; Like this; No matter whether storage battery has damaged still in charging process overcharges, and charger all still can charge to storage battery, and the batteries of dehydration or sulfuration is further worsened; Have a strong impact on the useful life of storage battery, bring unnecessary economic loss to the user.For addressing the above problem, the measure of taking at present is to reach the charge protection to storage battery through monitoring charge in batteries voltage.But, can not reach every monolithic storage battery in the whole group storage battery is monitored and protected, like this because it is monitored whole group storage battery; Still can not in time monitor out the charge condition of monoblock battery; Whether promptly damage or overcharge, because batteries is composed in series by a plurality of monoblock battery, its charge and discharge process also is a series system; Therefore, this monitoring mode has significant limitation to the degree of protection of storage battery.
Summary of the invention
The purpose of the utility model is to propose a kind of intelligent battery charger; This charger is through increasing the battery damage detection and preventing the over-charge protective function; Each element cell in the batteries all detected and in time prevent overcharge, effectively improve the useful life of storage battery and the stability of use.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of intelligent battery charger comprises power supply input circuit, single-chip microcomputer, power control circuit and feedback circuit; Voltage becomes HVDC and exports power control circuit behind the power supply input circuit rectifying and wave-filtering; The charging voltage of power control circuit output and electric current output to storage battery and feedback circuit after the single-chip microcomputer modulation, single-chip microcomputer clocked to the charging interval simultaneously; Feedback circuit outputs to single-chip microcomputer with the voltage of detected each element cell of batteries, and single-chip microcomputer is according to the output signal of the feedback signal control power control circuit of feedback circuit.
Said single-chip microcomputer inside is with the PWM program, charging timing program, AD conversion program and power supply control program.
Said single-chip microcomputer makes the charger output produce positive negative pulse stuffing through the control to Q1, Q3 in the power control circuit, has realized the charging of positive negative pulse stuffing formula.
Said single-chip microcomputer carries out data processing through detecting charging latter end output voltage, electric current and whole charging intervals of record.
Said single-chip microcomputer inside is also with alert program, and control DS1, DS2 in time reports to the police and prevent that the charging interval is long.
The utility model is owing to increased detection battery damage situation and anti-over-charge protective function on the architecture basics of existing charger; Timing program through charging interval of in little intelligent chip IC, programming; The time of record and the each charging of storage storage battery, and respectively the charging interval data of each element cell in the batteries are analyzed, wherein; It is unusual that charging interval appears in the arbitrary element cell in the batteries; Single-chip microcomputer (IC chip) triggers alert program through the processing to data, and the prompting user in time safeguards storage battery.Because charger can write down automatically and store effective charging interval, therefore, can the automatic disconnection protection, prevent that charging interval long causing from overcharging.The closed-loop control that single-chip microcomputer and voltage and current detection circuit form makes the adjusting of charging voltage, electric current very flexible on the one hand, and the stability of a system is strengthened.It is simple to have circuit, and cost is lower, characteristics such as stable performance.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The described intelligent electric bicycle charger of the utility model comprises single-chip microcomputer (IC chip), power supply input circuit A and power control circuit B; Feedback circuit C forms, and what power supply input circuit A, power control circuit B and feedback circuit C adopted is known circuit.In single-chip microcomputer inside with the PWM program, the charging timing program, AD conversion program and power supply control program etc.; It controls power control circuit B output charging voltage and electric current on the one hand; Adjust in real time simultaneously, on the other hand, effective charging interval is carried out timing according to feedback circuit C; And the preservation data, prevent to overcharge through control to the charging interval.If charge in batteries overlong time or too short explains that then internal has dehydration or sulfuration problem, through alert program, carries out alarm.Its charging modes is divided into conventional repid discharge, two processes of three stages charging, and purpose makes the battery lead plate sulfation drop to minimum level.
The utility model charging modes is as shown in Figure 2, promptly respectively to batteries 1,2,3,4 ... Each element cell among the N detects and controls.The detection of each unit is all identical with control mode.Fig. 3 is the wherein detection and the control mode of an element cell: the 220V/AC alternating current becomes HVDC through power supply input circuit A rectifying and wave-filtering.Produce pwm pulse driving power metal-oxide-semiconductor Q2, Q5 through the Q1 in the power control circuit, Q3, and carry out voltage transformation, produce output voltage with this control impuls transformer.Single-chip microcomputer is through effective charging interval of internal processes opening entry simultaneously.In charging process; Feedback voltage and electric current cushion to isolate or amplify through the U1 discharge circuit and are input to single-chip microcomputer; Single-chip microcomputer is through carrying out real-time sampling and A/D conversion to the size of output voltage, electric current; Then the reference value of setting in data that obtain and the program is compared, adjust output voltage, electric current in real time.The closed-loop control system that single-chip microcomputer and voltage and current detection circuit form makes the adjusting of charging voltage, electric current very flexible on the one hand, and the stability of a system is strengthened.Single-chip microcomputer makes the charger output produce positive negative pulse stuffing through the control to Q1, Q3 in the power control circuit, has realized the charging of positive negative pulse stuffing formula.Through detecting charging latter end output voltage, electric current and whole charging intervals of record, single-chip microcomputer carries out data processing.If judge arbitrary element cell in the batteries because inner sulfuration or dehydration cause self having to a certain degree to be damaged, system will control DS1 through alert program, DS2 in time reports to the police, and battery is safeguarded or changed in prompting.If the storage batteries D behaviour in service is good, after being full of electricity, system no longer continues automatic disconnection charging and prevents to overcharge.
