TECHNICAL FIELD

[0001] The present application relates to the technical field of special vehicle engineering, and in particular to a vehicle-mounted battery charging and discharging control method and system based on a display control device. BACKGROUND

[0002] In the design of special vehicles, the chassis battery not only provides power for the chassis equipment, but also provides direct current power for the supercharged equipment, such as Figure 1 As shown, in order to realize that the supercharged charger and the chassis charger can both charge the supercharged battery and the chassis battery, the two groups of batteries are designed in parallel. It is found in many applications that when the chassis engine starts, the output voltage of the battery will be pulled down, and the lowest voltage can be about 10V, which is lower than the power supply voltage range (generally greater than 15V) of many supercharged equipment (such as diesel generator set start, communication equipment, positioning and orientation), and the instantaneous low voltage will cause the equipment to be powered off or restarted, which seriously affects the combat time, and even good combat opportunities can be lost.

[0003] Currently, in order to solve the problem of low voltage during power supply of supercharged electrical equipment, a scheme of adding a voltage stabilizing power supply is adopted, as shown in Figure 2 The voltage stabilizing power supply is added between the supercharged battery and the intelligent power distribution equipment, and the voltage stabilizing power supply is used to stabilize the output power supply voltage of the battery within a usable range, so as to ensure the normal power supply of the supercharged electrical equipment. The DC-DC module of the voltage stabilizing power supply selects a power supply module with a wide input range, which can maintain a stable voltage output when the input voltage changes within the allowable range of the voltage stabilizing power supply module.

[0004] However, in the scheme of adding a voltage stabilizing power supply, the influence of power on cost, volume and weight needs to be considered, and the importance of supercharged equipment power consumption needs to be distinguished.

[0048] The preferred embodiments of the present application will be specifically described below in combination with the drawings, wherein the drawings constitute a part of the present application, and are used to explain the principles of the present application, and are not used to limit the scope of the present application.

[0049] One specific embodiment of the present application discloses a vehicle-mounted battery charge-discharge control system based on a display control device, as shown in Figure 3

[0050] Specifically, the vehicle-mounted battery includes a chassis battery 1 and an upper-mounted battery 2, the chassis battery 1 is connected with a chassis electrical device 3 and a chassis charger 4 respectively; the charge-discharge control system includes:

[0051] an isolating switch 5 connected in parallel between the chassis battery 1 and the upper-mounted battery 2;

[0052] an intelligent power distribution device 6, for connecting the upper-mounted battery 2 with an upper-mounted charger 7 and an upper-mounted electrical device 8 through the intelligent power distribution device 6; monitoring the working state of the upper-mounted electrical device, the working state of the upper-mounted charger and the battery power information of the upper-mounted battery, sending the information monitored by the intelligent power distribution device 6 to a display control device 9; starting the upper-mounted battery 2 to supply power to the upper-mounted electrical device 8 or starting the upper-mounted charger 7 to charge the upper-mounted battery 2 according to the control instruction of the display control device 9;

[0053] a chassis controller 10, for collecting the working information of the chassis electrical device and the battery power information of the chassis battery, and sending the information collected by the chassis controller to the display control device 9;

[0054] the display control device 9, receiving the information monitored by the intelligent power distribution device and the information collected by the chassis controller, and receiving the chassis device starting instruction and the on-off state of the isolating switch 5, for controlling the on-off of the parallel connection of the chassis battery 1 and the upper-mounted battery 2 according to the received information, and for controlling the upper-mounted battery 2 and / or the chassis battery 1 to supply power to the upper-mounted electrical device through the intelligent power distribution device 6, or controlling the upper-mounted charger or the chassis charger to start charging the vehicle-mounted battery.

[0055] Specifically, in the design of the vehicle-mounted battery charge-discharge of the special vehicle, as shown in Figure 1 in order to realize the mutual charging of the chassis battery 1 and the upper-mounted battery 2 by the upper-mounted charger 7 and the chassis charger 4, the chassis battery 1 and the upper-mounted battery 2 are designed in parallel, when the voltage of one group of batteries is pulled down, the voltage of the other group of batteries will also be pulled down synchronously, and it is found in the application that when the chassis electrical device 3 (such as the chassis engine) is started, the output voltage of the battery will be pulled down, which is lower than the power supply voltage range of many upper-mounted electrical devices 8 (such as diesel generator set, communication equipment, positioning and orientation, etc.), the instantaneous low voltage will cause the upper-mounted electrical device 8 to be powered off or restarted, which seriously affects the combat time, and even good combat opportunities will be lost.

[0056] as shown in Figure 2 ​As shown, the existing improvement method for battery voltage pull-down is to increase the voltage stabilizing power supply on the basis of the original circuit, and the voltage stabilizing power supply is increased between the upper-mounted battery 2 and the intelligent power distribution device 6. The voltage stabilizing power supply makes the battery output power voltage stable within the available range, and ensures the normal power supply of the upper-mounted device. The voltage stabilizing power supply DC-DC module selects a power module with a wide input range. When the input voltage changes within the allowable range of the voltage stabilizing power supply, a stable voltage output can be maintained. However, considering the influence of power on cost, volume and weight, it is necessary to distinguish the importance of power consumption of each electrical device in the upper-mounted electrical device 8, select the key devices for statistics, such as communication devices, and design the voltage stabilizing power supply to maintain the stable power consumption of the key devices. However, this scheme needs to design new circuit and combined structure, and also needs to design structure interface for installation and reserve installation space, which is complex in design, complex in interface, long in cycle, and also increases the cost.

[0057] Specifically, the embodiment is based on the existing display control device 9 and the existing circuit in the existing special vehicle, and the situation of preventing the vehicle-mounted battery voltage from being pulled down is realized through the increase of the disconnecting switch 5 and the monitoring interface, and the corresponding operation control. The embodiment has the advantages of simple design, simple interface, low cost and strong expandability.

[0058] Specifically, in order to prevent the vehicle-mounted battery voltage from being pulled down when the chassis electrical device 3 (such as chassis engine) starts, it is necessary to disconnect the power supply connection between the chassis battery 1 and the upper-mounted electrical device 8 in advance when the chassis electrical device 3 (such as chassis engine) starts, while still maintaining the connection between the upper-mounted battery 2 and the upper-mounted electrical device 8, and maintaining the stable power supply of the upper-mounted electrical device 8 for a short time. More specifically, the embodiment designs the disconnecting switch 5 connected in parallel between the chassis battery 1 and the upper-mounted battery 2 to realize the on-off control of the chassis battery 1 and the upper-mounted battery 2; specifically, in normal operation, the disconnecting switch 5 is closed, the chassis battery 1 and the upper-mounted battery 2 are connected in parallel, and the upper-mounted electrical device 8 is powered together; when the chassis electrical device 3 (such as chassis engine) starts, the connection between the chassis battery 1 and the upper-mounted battery 2 is disconnected, and the stable power supply of the upper-mounted electrical device 8 for a short time is ensured.

[0059] More specifically, in the embodiment, when the voltage between the chassis battery 1 and the upper-mounted battery 2 is different, the current between the two groups of batteries is large. Considering the convenience and safety of operation and installation, the control mode of the disconnecting switch 5 is designed to control the on-off of the large current circuit between the upper-mounted battery 2 and the chassis battery 1 through the small current circuit in the disconnecting switch 5 controlled by the display control device 9, so as to realize the control of the on-off of the upper-mounted battery 2 and the chassis battery 1.

[0060] The problem of abnormal power supply of the upper-mounted electrical equipment 8 caused by the low battery voltage of the bottom chassis battery 1 when the bottom chassis battery 1 has a large current output can be solved by controlling the disconnection of the upper-mounted battery 2 and the bottom chassis battery 1 through the isolating switch 5, and the stable operation of the upper-mounted electrical equipment 8 is ensured; the mutual charging of the bottom chassis battery 1 and the upper-mounted battery 2 by the upper-mounted charger 7 and the bottom chassis charger 4 can be realized by controlling the closure of the upper-mounted battery 2 and the bottom chassis battery 1, and the use of the two groups of batteries to supply power to the upper-mounted electrical equipment 8 ensures the working time length of the upper-mounted electrical equipment 8.

[0062] Specifically, the bottom chassis controller 10 is used for collecting the working information of the bottom chassis equipment and sending the working information of the bottom chassis equipment to the display control equipment 9; the working information of the bottom chassis equipment includes the working state of the bottom chassis electrical equipment 3 and the power information of the bottom chassis battery 1;

Specifically, after the display control device 9 detects the chassis electrical equipment starting instruction, the display control device 9 sends the disconnecting switch 5 control instruction to the intelligent power distribution device 6 to disconnect the disconnecting switch 5 in advance to ensure normal power supply of the upper electrical equipment 8; at the same time, after detecting the working state of the chassis charger 4, the display control device 9 sends a control signal to the intelligent power distribution device 6 to control the upper charger 7 to stop outputting, so as to ensure the working interlocking of the upper charger 7 and the chassis charger 4 and ensure that only one charger works at the same time.
