Abstract
The utility model discloses a charger for maintaining a lead-acid storage battery of an electrocar. The charger comprises a rectification circuit, a current control circuit, a transformer voltage transformation/stabilization circuit, a double voltage-stabilizing circuit and an alternating voltage generator and is mainly characterized in that the double voltage-stabilizing circuit is connected with an environmental temperature detection circuit; and the alternating voltage generator is connected with a voltage detection circuit, so as to generate a current with different intensity and a voltage with different intensity for intensifying the lead sulfide of a pole plate of the battery, so that the electric potential in the storage battery can be alleviated, and the temperature rise is reduced, thereby reducing the water loss and avoiding the hardening of the pole plate as the storage battery is undercharged. The voltage detection circuit, a voltage negative feedback circuit and the current control circuit are connected with one another, so as to generate the high voltage with low output current and the lower voltage with high output current, thereby reducing the temperature rise in the storage battery.
Description
Technical field: the utility model relates to a kind of improvement invention of lead-acid battery of electric vehicle charger.
Background technology: in the prior art, the charger of the lead acid accumulator of producing is imported from the 220V alternating current both at home and abroad, pass through the back after testing output current of rectification circuit, current control circuit, transformer transformation, voltage stabilizing circuit, electric current to charge in batteries, the dehydration of this charging modes battery is too much, storage battery vulcanization is serious, pole plate sclerosis etc., the lost of life.
Domestic and international comparatively ideal electric motor car special charger is to use constant current source charging earlier at present, changes the constant pressure source charging again over to, enters floating charge at last, and this mise-a-la-masse method has three big shortcomings:
Electric current was excessive when one, charger was charged to storage battery actual capacity 75%, caused battery internal temperature to raise and dehydration.
Two, charger can not get discharging to lead acid accumulator energy of position in the trickle charge process, causes temperature rising dehydration, and shortens the life-span.
Three, charging at once after each electric motor car user can not drive at every turn, and each charging also can not be with the storage battery abundance, when the indicator light red light transfers green light to, accumulator electric-quantity in fact only reaches 90%, the user thinks by mistake sufficient, below either way can cause the accumulator plate sulfuration, accelerate scrapping of storage battery.
Summary of the invention: in view of the technical problem of known technology existence, the purpose of this utility model aims to provide a kind of accumulator plate of can eliminating and vulcanizes, this removing method is the vulcanized lead that accumulator plate every day produces is intensified and divide, when battery tension raises, and the output current minimizing, produce the charging of diving, make internal storage battery that dehydration is reduced, simultaneously, when variation of ambient temperature, automatically regulate the output ceiling voltage and float, make storage battery can be fully loaded with charging towards voltage.
The utility model is finished as follows: charger includes rectification circuit, current control circuit, the transformer transformation, voltage stabilizing circuit, the bistable volt circuit, alternate voltage-changing generator, it is characterized in that on the circuit board of charger, being provided with the bistable volt circuit, ambient temperature detection circuit, voltage detecting circuit and voltage negative feedback circuit, described bistable volt circuit is connected with ambient temperature detection circuit, alternate voltage-changing generator is connected with voltage detecting circuit, voltage detecting circuit is connected with voltage negative feedback circuit, voltage negative feedback circuit and current control circuit constitute the loop, and on the housing of charger, be provided with red, green indicator light is in order to the charge condition of supervision storage battery.
The utility model is compared with known technology, the alternate voltage-changing generator that is provided with between voltage stabilizing circuit and current detection circuit is electrically connected with voltage detecting circuit, produce the underriding electric current, reducing temperature raises, dehydration reduces, and can regulate the output ceiling voltage automatically and float towards voltage according to ambient temperature, and the boost charge device is to the dynamics that intensifies of storage battery, charging is sufficient, the useful life of having improved storage battery significantly.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is the utility model circuit structure block diagram
Fig. 2 is the utility model current curve diagram
Embodiment: accompanying drawing has represented to describe in conjunction with the accompanying drawings below structure of the present utility model and the embodiment each relevant details and operation principle thereof of embodiment again:
Referring to figure one: whole charger includes rectification circuit, current control circuit, the transformer transformation, voltage stabilizing circuit, the bistable volt circuit, voltage detecting circuit, voltage negative feedback circuit and ambient temperature detection circuit, these circuit are routine techniques, in existing charger, also generally use, its circuit structure needn't explain again, its principal character is that bistable piezoelectricity pressure is electrically connected with ambient temperature detection circuit, alternate voltage-changing generator is electrically connected with voltage detecting circuit, voltage detecting circuit is electrically connected with voltage negative feedback circuit, like this when alternating current 220V voltage during to charge in batteries, electric current will charge by the square frame principle of electronic circuit shown in Figure 1, in the o-a of Fig. 2 part, the present invention adopts voltage negative feedback circuit, when battery tension raises, output current reduces (charging of diving), its objective is that reducing the battery internal temperature rising reduces dehydration, in the a-b of Fig. 2 part, when battery tension reaches about 1.22 times of rated voltages, the voltage detecting circuit output order, change charging method, the charging of employing alternating voltage, the alternating voltage amplitude is up to more than 4.5 volts, alternating voltage produces the intermittent current of a varying strength, the vulcanized lead that produces accumulator plate every day is intensified and divide, eliminate the sulfation of accumulator plate, owing to adopt alternating voltage, make the internal storage battery energy of position obtain relaxing, reduce temperature and raise, dehydration is reduced, can prolong the useful life of storage battery effectively.
This charger utilizing ambient temperature detection circuit, when ambient temperature raises, output ceiling voltage and float charge voltage descend thereupon in the bistable volt circuit, when ambient temperature descends, output ceiling voltage and float charge voltage rise thereupon, with charger free charge in batteries is intensified dynamics and make the charge in batteries deficiency inadequately, and produce the accumulator plate sclerosis.Charging process changes the indication of three stages into by the two stages indication of original charging indication in addition, show with red, green indicator light, this moment is because the o-b district all is that red light or green light flicker reality is all in charging to the a-b district, only arrive the b point at electric weight, i.e. charging finishes, green light is just bright, and charger enters floating charge state.So just can effectively overcome, produce the too short difficult problem in useful life that plate vulcanizing causes owing to charge volume is not enough.
Lead-acid battery of electric vehicle according to the utility model design motif made is safeguarded charger, brings positive result of use will for the electric motor car user.
