Most rolling stock is also provided with a vehicle-mounted charging device, but the power supply of a control system of the rolling stock comes from a storage battery, and the control system cannot be started under the condition of power shortage of the storage battery, so that the charging device cannot charge the storage battery.
It is also known to determine whether the voltage of the accumulator is lower than a predetermined voltage before the charging of the on-board charging device, and if so, to activate the charger module with another power supply device. The charging device selects the power supply device through a plurality of transfer switches, which is disadvantageous in terms of cost, cumbersome operation, intelligence, and reliability.

Advantageously, according to the invention, the battery voltage detection device is designed as a battery voltage detection button which has a normally open self-locking function.
According to the invention, a battery charging system is also proposed for a rail transit locomotive composed of two locomotives, each locomotive being provided with a battery charging device according to the invention, wherein the load interfaces of the battery charging devices are connected to each other.
The invention also provides a rail transit locomotive which is formed by combining two locomotives, wherein the two locomotives respectively comprise the storage battery charging device.
According to the invention, a charging method for charging a rail vehicle battery is also proposed, which is carried out using the above-described battery charging device according to the invention, having the following steps:
when the locomotive storage battery needs to be charged, the voltage of the storage battery is detected by a storage battery voltage detection device;
when the voltage of the storage battery is within the set range and the power input interface of the power starting module has correct input voltage, the power output interface of the power starting module outputs the voltage to the power input interface of the control system of the charger module to supply power to the control system of the charger module so as to start the charger module.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.

Likewise, references to a feature or aspect are intended to describe a feature or aspect of an example of the invention and do not imply that every embodiment thereof must have the described feature or aspect. Further, it should be noted that the description shows a number of features. While certain features have been combined to illustrate a potential system design, other combinations not explicitly disclosed may also be employed for these features. Accordingly, the combinations are not intended to be limiting unless otherwise specified.
In the embodiments shown in the drawings, directional references such as up, down, left, right, front and rear, etc. are not absolute, but relative, and are used to explain the structure and movement of various components of the present invention. These representations are appropriate when the components are in the positions shown in the figures. However, if the description of the location of an element changes, it is believed that these representations will change accordingly.
Fig. 1 shows a schematic diagram of a battery charging device 1. The invention relates to a storage battery charging device 1, in particular to an intelligent storage battery charging device which is used for an intelligent charging system of a rail transit locomotive to charge a vehicle-mounted storage battery of the locomotive. Rail transit locomotives are for example harmonious electric locomotives, in particular HXD1 locomotives and HXD2 locomotives. Such rail transit locomotives are typically combined from two locomotives, each being used to operate in opposite directions.
The input power of the intelligent charging system according to the invention must have the same standard as the ground power 400 of the rolling stock, such as AC380V or DC750V, DC 600V. In the normal use process of the rolling stock, the power supply can be input to the VIN of the storage battery charging device 1 through an AC/DC or DC/DC conversion device by a contact network or an energy storage device, and the ground power supply 400 can be directly connected to the VIN of the storage battery charging device 1 in a garage with the ground power supply 400.
When the storage battery of the rolling stock needs to be charged, the storage battery voltage detection button SB is pressed, CTRL + of the detection interface 120 of the power supply start module 100 detects the storage battery voltage, and when the voltage is within a set range (the set range can be adjusted according to the demand condition) and VIN has a correct input voltage, OUT + of the power supply start module 100 supplies the output voltage to the control system of the charger module 200; after the control system of the charger module 200 is started, the input voltage of the ground power supply 400 is received from the charger module power input interface 210, the OUT1+ outputs the voltage to charge the storage battery, at this time, when the CTRL + of the power supply start module 100 detects that the voltage exceeds the set range, the power supply start module 100 stops working, and the subsequent charging work is completed only by the charger module 200.
According to one embodiment of the invention, CTRL-, OUT-of the power supply startup module 10 and OUT-of the charger module 200 are connected to the battery.
According to one embodiment of the present invention, at least 2 diodes are passed between the battery interface 500 of the vehicle-mounted battery and the charger module power output interface 230 of the charger module 200: battery interface 500 → first diode 310 → third diode 330 → control system power input interface 220 (battery + → diode D1 → diode D3 → VCC +).
The circuit formed by the battery voltage detection button 340, the first diode 310, the second diode 320, the third diode 330 and the corresponding connecting lines forms a peripheral circuit or a detection and protection circuit 300, and the detection and protection circuit 300 comprises two parts, namely a detection circuit and a protection circuit.
According to one embodiment of the present invention, the detection circuit is: battery interface 500 → first diode 310 → battery voltage detection device 340 → detection interface 120 (battery + → D1 → SB → CTRL +). The battery voltage detection point 350 is located between the first diode 310 and the load interface 600.
According to an embodiment of the present invention, the protection circuit is a circuit formed by a first diode 310, a second diode 320, and a third diode 330.
The first diode 310 is used to prevent the batteries from being directly connected when two identical circuit load interfaces 600 are connected (i.e., load interfaces 600 of charging circuits of two identical locomotives, such as HXD1 locomotive or HXD2 locomotive, are electrically connected to each other). According to an essential feature of the invention, at least one diode is arranged between battery interface 500 and load interface 600.
The second diode 320 is used, for example, to prevent the power starting module 100 from malfunctioning in its internal circuit, which may result in the locomotive not being used normally.
The third diode 330 has two functions. First, it is used to prevent the low power supply starting module 100 from supplying power to the high power load; secondly, if the diode is not provided, the OUT + is prevented from being directly output to CTRL +, which causes the voltage to be respectively sent to CTRL + and VCC + after the OUT + is started, and the OUT + output is stopped when the CTRL + detects that the voltage is normal, and at this time, the charger module 200 may not be started normally, which causes the circuit to be unable to work normally.
According to an embodiment of the present invention, when only one intelligent charging device 1 is used, the normal detection circuit is, as described above, the battery interface 500 → the first diode 310 → the battery voltage detection device 340 → the detection interface 120, CTRL + detects whether the battery voltage is within the set range, and when the battery voltage is within the set range and the power source start module power source input interface 110 has the correct input voltage, the power source start module power source output interface 130 outputs the voltage to the control system power source input interface 220 of the charger module 200 to supply power to the control system of the charger module 200 for starting the charger module 200. According to the invention, a logic protection diode, i.e. a first diode 310 is provided, which first diode 310 may cause a 0.7V (negligible) voltage drop, but which has no effect on the circuit function.
Fig. 2 shows a battery charging system according to the invention with an integrated battery charging device. When two identical circuit load interfaces 600 are connected, and one battery is in a power-deficient state, and the other battery is in a normal state, if the voltage detection point 350 is located on the load line according to the present invention, both charger modules 200 can be started by the battery with normal voltage (normal battery → D1 → load line → two D3 → two VCC +), without starting the power starting module 200. If the voltage detection point 350 is on the storage battery +, the storage battery under-voltage charger module 200 cannot be started by the storage battery with normal voltage, and the charger module 200 can be started only after the power supply starting module 100 is started.
According to an embodiment of the present invention, the button controls the hard-wired circuit to compare the voltages of the batteries in the intelligent battery charging system, and when the voltages are within the set value range and the input circuit has an input voltage, the power starting module 100 starts to operate, and further the charger module 200 is started to charge the batteries. The intelligent storage battery charging system comprises a power supply starting module 100, a charger module 200 and a peripheral detection and protection circuit 300.
According to one embodiment of the present invention, the power up module 100 is composed of an input detection circuit, a battery detection circuit, a CPU control circuit, and an output circuit.
The peripheral detection and protection circuit 300 is composed of a storage battery voltage detection device 340, a logic protection diode and other devices.
If the battery detection circuit of the power supply starting module 100 detects that the voltage of the battery is in a certain specific interval, and meanwhile, the input detection circuit judges that the input voltage is in a correct range, the CPU control circuit controls the output circuit to start.
The battery voltage detection device 340 is configured as a battery voltage detection button, for example, a normally open self-locking function button.
The battery and power supply start module 100 provides the control power supply input for the charger module 200 through the combination of the diode circuits in the peripheral detection and protection circuit 300.
The power supply startup module 100 does not directly charge the battery.
At least two diodes are arranged between the storage battery and the control system power input interface 220 of the charger module 200.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The description herein is intended to be illustrative, and not to limit the scope of the claims. Various alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, methods, and other characteristics of the exemplary embodiments described herein may be combined in various ways to produce additional and/or alternative exemplary embodiments.
As the present features may be embodied in several forms without departing from the characteristics of the present invention, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
