Description
Technical field
The utility model relates to the charger circuit technical field, specifically a kind of positive reversal connection double acting charger charging circuit.
Background technology
Electric motor car is also inequality because of the both positive and negative polarity of the different batteries of brand on the existing market, so electric car charger must match with the brand of oneself, there will be two kinds of situations if cause charger and battery to connect anti-back under the situation that charger is used with easily: 1. charger burns out; 2. can't charge to electric motor car.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of positive reversal connection double acting charger charging circuit is provided.
The technical solution of the utility model realizes in the following manner, this positive reversal connection double acting charger charging circuit, its structure comprises first input power cord, second input power cord, output cathode line and output negative pole line, first input power cord is connected on first relay, second input power cord is connected on second relay, be connected with the loop between first relay and second relay, be in series with opposite two the anti-short circuit diodes that are provided with of direction on the loop, first input power cord, be parallel with first detection line and second detection line between second input power cord respectively, two joints of output negative pole line series connection are connected on first relay and second relay, and the output cathode line is connected between two anti-short circuit diodes that direction is opposite on the loop.
First detection line is provided with first relay monitoring coil and first and detects diode, and first relay monitoring coil is connected with first relay; Second detection line is provided with second relay monitoring coil and second and detects diode, and second relay monitoring coil is connected with second relay; It is opposite that the first detection diode and second detects the diode direction.
The beneficial effect that the utility model is compared with prior art produced is:
This positive reversal connection double acting charger charging circuit is simple in structure, safe charging, be convenient to produce and promote, and can increase the charger reliability during operation.
After can detecting the both positive and negative polarity circuit earlier, exports by this positive reversal connection double acting charger charging circuit, if opposite this circuit with battery plus-negative plate of charger transposing both positive and negative polarity automatically matches its charger and battery plus-negative plate, avoid charger to burn out maybe and can't give the electric motor car charging phenomenon.
This circuit is under charger and situation that battery does not conform to:
A. this circuit first input power cord is under the situation of positive pole, be judged as positive pole because second detects diode, so electric current is by second relay monitoring coil, the second relay adhesive realizes that battery plus-negative plate and charger output both positive and negative polarity match, and charge normal battery.
B. the first detection diode is judged as forward when first input power cord is negative pole, and first relay monitoring coil has electric current to pass through, the first relay both positive and negative polarity convert charging device adhesive.Realize that battery plus-negative plate and charger output both positive and negative polarity matches, and charges normal battery.
It is that negative or positive electrode all can't directly cause short circuit that the design that is in series with opposite two the anti-short circuit diodes that are provided with of direction on the loop makes first input power cord.
