Embodiment 1

[0044] The battery charger provided in this embodiment is a charger that is installed on the train and cooperates with the battery. When the battery is fed, it can be started by inputting an external AC power to the battery charger. In this way, it is avoided to use the ground charger to charge the battery. When the battery is charged, cut off the external AC power, and use the DC power of the battery to control the train network system, diesel engine control system (internal-combustion multiple unit / internal-combustion locomotive) and the bow The control system starts normally, and the battery also provides DC power for the control circuit of the charger. The main circuit of the charger obtains AC power after the diesel engine control system is started, that is, after the battery works normally, the charger starts normally under the action of the battery. When the charger is working normally, it supplies power to the DC load of the whole vehicle and charges the battery.

Embodiment 2

[0056] figure 2 It is a schematic structural diagram of the second embodiment of the battery charger of the present invention. Further, on the basis of the above embodiments, this embodiment also includes:

[0057] Control the protection circuit 105, the control protection circuit 105 is used to control and control the power conversion module 103 to stop supplying power to the control circuit 102 when detecting that the input AC power of the main circuit 101 is powered by the AC power supply group 300 on the train; When the input alternating current is powered by the alternating current on the ground, the control power conversion module 103 is controlled to convert and supply power to the control circuit 102, that is, the control and protection circuit 105 is set in the charger to realize the interlocking of the external main circuit 101 AC power supply and the train's own AC power supply. The purpose of this is to realize the interlocking of the DC power supply of the batter...

Abstract

The invention provides a storage battery charger. The storage battery charger comprises a main circuit and a control circuit, wherein an input end of the main circuit is connected with an AC power supply set of a train, an output end of the main circuit is connected with a storage battery and a DC load of the train, an input end of the control circuit is connected with the storage battery, an external connection AC socket and a control power source conversion module are further comprised, the external connection AC socket is connected with the input end of the main circuit, an input end of the control power source conversion module is connected with the input end of the power source, an output end of the control power source conversion module is connected with the input end of the control circuit, the control power source conversion module is used for converting AC current of the ground introduced by the external connection AC socket into a DC current and providing the DC current for the control circuit, and the control circuit is enabled to acquire the DC current for operation. The storage battery charger is advantaged in that a technical problem of operation cost increase caused by employing a ground surface charger to charge the feeding storage battery can be solved.

Description

technical field [0001] The invention relates to the technical field of electrical auxiliary power supply, in particular to a zero-voltage starting storage battery charger. Background technique [0002] Battery chargers (hereinafter referred to as chargers) are auxiliary power supply equipment used on all locomotives, motor vehicles, vehicles and related facilities powered by batteries (hereinafter collectively referred to as trains), especially for internal combustion / electric multiple units, internal combustion / electric power It is an essential equipment for locomotives and various passenger vehicles. After the charger starts to work, it can convert the input AC380 50HZ alternating current into direct current (DC24V / DC48V / DC72V / DC110V) through rectification, inverter and transformation, etc., to supply power for the DC equipment on the train, and the charger starts at the same time The battery pack can then be charged. [0003] Among them, the prerequisites for the charge...
