Description

The multiway combined type charger

Technical field

The utility model relates to the pulsed battery charger, especially relates to the multiway combined type charger.

Background technology

The pulsed battery charger has solved the irreversible sulfation problem that lead acid accumulator in use occurs well.As Chinese utility model patent number: ZL200620004733.3, title: " the lead acid accumulator pulse instrument for repairing that has protective circuit "; this patent has not only solved the problems referred to above, has also stopped simultaneously lead acid accumulator phenomenon because of charging terminal reversal connection, short circuit damage equipment when the charging.But this instrument for repairing also has weak point, i.e. charging is output as one tunnel output, and the employed storage batterys of power consumption equipment such as present electronic two-wheeled, tricycle mostly are series connection use in groups, need connect when therefore charging and charge; But, the difference of each accumulator internal resistance, capacity has electrical potential difference between the storage battery because making, and serial connection charge will cause this electrical potential difference increasing repeatedly, finally cause the voltage of some storage batterys to be lower than its final voltage and scrap, cause batteries to scrap, greatly reduce the useful life of batteries.

The utility model content

The utility model purpose is the further improvement that above-mentioned patent is done, and a kind of multiway combined type charger is provided, and with realization each cell in the series connection batteries is independently charged simultaneously.

For achieving the above object, the utility model can be taked following technical proposals:

Multiway combined type charger described in the utility model, it comprises housing, is arranged on the charhing unit of being made up of impulse circuit, charge protector, field effect transistor and rectification circuit in the described housing; Impulse circuit in the described charhing unit is the impulse circuit in the existing lead acid accumulator pulse instrument for repairing, and it has direct-current control voltage output and pulse signal output end; Charge protector in the charhing unit is made of photoelectric coupled circuit, the anodal series arm that constitutes by resistance, diode of the light-emitting diode of described optocoupler input is connected with the rectification circuit output end positive electrical with the charger output head anode, the light-emitting diode negative pole of optocoupler input is electrically connected with charger negative pole of output end and field effect transistor drain electrode respectively, the transistor emitter ground connection of optocoupler output and collector electrode is electrically connected with the direct-current control voltage output of impulse circuit, the source ground of field effect transistor and grid is electrically connected with the pulse signal output end of impulse circuit; Described charhing unit is a plurality of, and the input of the rectification circuit in each charhing unit is electrically connected with the secondary one group of coil windings of single-phase rectifier transformer respectively.

The utility model advantage just is to be arranged on a plurality of charhing units of being made up of impulse circuit, charge protector, field effect transistor and rectification circuit in the described housing; And the input of the rectification circuit in each charhing unit is electrically connected with the secondary one group of coil windings of single-phase rectifier transformer respectively.Therefore, when the series connection batteries is charged, respectively the series arm that is made of described resistance, diode in each charhing unit is electrically connected with a battery positive voltage, gets final product and the light-emitting diode negative pole of optocoupler input is electrically connected with this battery terminal negative; Thereby realize each cell in the series connection batteries is independently charged simultaneously, make the voltage of each piece storage battery be consistent substantially, compensated between the storage battery owing to internal resistance, capacity is different produces electrical potential difference, has prolonged the useful life of batteries greatly.Also reduced simultaneously and scrapped storage battery pollution that environment caused.
