Description
Technical field:
The utility model relates to battery charger, particularly a kind of charging dropping equipment for vehicular high-power battery pack in the railway system.
Background technology:
Large-capacity battery group is widely used in passenger train system, and Main Function is for providing startup power supply or being emergence power stand-by power supply.During bus driving, mobile generator is that on car, electrical appliance is powered, simultaneously accumulators group charging, and when passenger vehicle stops, just use battery pack is powered for electrical appliance on car.So battery pack is all in charged state at most times.But due to restrictions such as cost, volume, technical difficulty, the charger of specialty can not be installed for cell stack designs in passenger train, but battery pack is simply connected in parallel on generator output end and charges, normal when running generator directly to battery charging; But because generator voltage can't just match battery group nominal charging voltage, generally can higher than battery rated voltage, this just causes battery pack after long-time high voltage charging, and hydraulic performance decline even damages.
Summary of the invention:
The purpose of this utility model is that a kind of result of use of design is good, high power battery group charging dropping equipment rational in infrastructure.
The technical solution of the utility model is, a kind of high power battery group charging dropping equipment, and it comprises housing, it is characterized in that: on housing, be provided with both positive and negative polarity interface, in housing, be provided with a voltage reduction module, be provided with the diode of two groups of parallel connections in voltage reduction module inside, and be packaged on metal substrate.The diode of two groups of parallel connections in described voltage reduction module, one group is made up of multiple charging diode, and the positive pole of this multiple charging diode is connected with the anode interface on housing, and the negative pole of this multiple charging diode is connected with the negative pole interface on housing; Another group diode is made up of a discharge diode, and the negative pole of this discharge diode is connected with the anode interface on housing, and the positive pole of this discharge diode is connected with the negative pole interface on housing.
Charging voltage effectively can be dropped to battery pack nominal charging voltage by the utility model, effectively can extend the life-span of vehicular high-power battery pack in the railway system, and have that structure is simple, cheap, reliability is high, power is large, install advantages such as convenient (can be arranged on any position of batteries).
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model, and Fig. 2 is using state figure of the present utility model.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, a kind of high power battery group charging dropping equipment, it comprises housing 4, housing is provided with both positive and negative polarity interface, in housing, be provided with a voltage reduction module 1, be provided with the diode of two groups of parallel connections in voltage reduction module inside, and be packaged on metal substrate 5; The diode being provided with two groups of parallel connections on metallic substrates described in the present embodiment, wherein one group is by multiple charging diode group 3 one-tenth, the positive pole of this multiple charging diode is connected with the anode interface on housing, and the negative pole of this multiple charging diode is connected with the negative pole interface on housing; Another group diode is made up of a discharge diode 2, and the negative pole of this discharge diode is connected with the anode interface on housing, and the positive pole of this discharge diode is connected with the negative pole interface on housing.
Operation principle of the present utility model is series-parallel relation of several diodes, by charger 6, whole battery pack 7 is charged, wherein the branch road of multiple charging diode series connection is charging paths, during charging, electric current flows to negative pole from positive pole, now discharge diode oppositely ends, and from the characteristic of diode, diode forward conducting voltage is fixedly about 0.7V, so when N number of Diode series, then total step-down is N × 0.7V.Upon discharging, electric current flows to positive pole from negative pole, discharge diode conducting, and charging diode ends, and total step-down is 0.7V.In actual design is produced, the series connection number of charging diode can be determined according to the step-down value of actual service condition or customer requirement.Because the use power of high power battery group charging dropping equipment is comparatively large, the radiator that heat radiation can be adopted good is to ensure that main decompression device can not cross cause thermal damage.High power battery group charging dropping equipment is connected on charger after connecting with the vehicular high-power battery pack of locomotive, and reducing transformer can be connected on any position (can be connected on charger positive pole, the negative pole even middle optional position of battery pack) of batteries, it is more convenient to install.
