Description
Technical field
The utility model relates to electric automobiles, relates in particular to a kind of explosion-proof battery carrier automatic charging control circuit.
Background technology
Battery car is the carrier in the commercial Application, works the haulage equipment of the effect of transporting goods, and is its power resources with chargeable storage battery.
But the charging interval of storage battery is longer, need after charging finishes artificially to cut off the charger power supply, otherwise charger keeps charging for a long time, and such one is unfavorable to charger and battery, the 2nd, and the waste electric energy, even the overheated burning of charger time appears.
The utility model content
The purpose of the utility model is to provide a kind of explosion-proof battery carrier automatic charging control circuit.
The purpose of the utility model realizes through following technical scheme.
A kind of explosion-proof battery carrier automatic charging control circuit comprises: the power supply, switching tube, current feedback circuit and the battery that link to each other successively, PWM testing circuit, charging current control circuit; Said charging current control circuit input termination battery, its output termination PWM testing circuit input, PWM testing circuit output termination switching tube input, the output of another input termination current feedback circuit of PWM testing circuit.
Preferably, said PWM testing circuit is the PWM integrated chip.
The utility model compared with prior art; Beneficial effect is: the explosion-proof battery carrier automatic charging control circuit that the utility model provides has simple in structure, easy to use; After the electric motor car charging interval arrives, can close whole power supplys timely automatically, play safe, energy-conservation order ground.
Description of drawings
Fig. 1 is the utility model explosion-proof battery carrier automatic charging control circuit theory diagram.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1ly, explosion-proof battery carrier automatic charging control circuit comprises: the power supply, switching tube, current feedback circuit and the battery that link to each other successively, PWM testing circuit, charging current control circuit; Said charging current control circuit input termination battery, its output termination PWM testing circuit input, PWM testing circuit output termination switching tube input, the output of another input termination current feedback circuit of PWM testing circuit.Wherein, the PWM testing circuit constitutes for the PWM integrated chip.
Charging current control circuit is judged battery according to voltage sampling signal; Provide charging control signal then, make PWM testing circuit output pwm signal control switch pipe output current, simultaneously; The PWM testing circuit is adjusted pwm signal according to current feedback signal, thus the size of adjustment output current.Be full of when charging current control circuit goes out battery according to the sampled voltage input, then export charging control signal, make the PWM testing circuit stop pwm signal output, thereby stop charging current output, complete charge.
The explosion-proof battery carrier automatic charging control circuit that the utility model provides has simple in structure, easy to use, after the electric motor car charging interval arrives, can close whole power supplys timely automatically, plays safe, energy-conservation order ground.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
