The application provides a controllable overlapping charging method, which aims to realize overlapping charging control on charging equipment by controlling the on-off of charging lines of the charging equipment which are mutually butted, so that the safety and controllability of the charging equipment are improved, and potential charging safety hazards are avoided. Compared with the existing stacked charging system, when stacked charging is carried out, a plurality of charging devices are stacked together for charging, and charging can be carried out as long as the charging devices are connected together in a butt joint mode for convenience of operation. And when charging, because a plurality of charging devices stack and charge, charging power can be great relatively, appears charging potential safety hazard easily. Therefore, the controllable overlapping charging method provided by the embodiment of the application is provided to solve the technical problems that an existing overlapping charging system is uncontrollable and has potential safety hazards.
The first embodiment is as follows:
fig. 1 shows a controllable superposition charging system provided in an embodiment of the present application, and referring to fig. 1, the controllable superposition charging system includes: the charging device comprises a main board, a power input end, a power output end, a front contact detection point and a rear contact detection point; the power supply input end is used for being butted with a charging power supply or the power supply output end of another charging device, connecting charging current to the corresponding mainboard and enabling each charging device to be sequentially butted; the main board is connected with the corresponding rear contact detection point and is used for controlling the conduction of a power supply input end and a power supply output end in the charging equipment when the rear contact detection point is detected to be in butt joint with the front contact detection point of another corresponding charging equipment, so that the charging current is transmitted between the charging equipment; the charging power supply is used for any charging equipment to be butted and outputting charging current to the power supply input end of any charging equipment. The power input end inside the charging equipment is in butt joint with the corresponding power output end through the relay, and the relay is controlled to be switched on and off through the mainboard. The power input end comprises a power input anode and a power input cathode, the power output end comprises a power output anode and a voltage output cathode, the power input anode is used for being butted with the anode of the charging power supply or the power output anode of another charging device, and the power input cathode is used for being butted with the cathode of the charging power supply or the power output cathode of another charging device; the main board is used for controlling the conduction of a power input anode and a power output anode in the charging equipment when the rear contact detection point is detected to be in butt joint with the front contact detection point of another corresponding charging equipment.
Specifically, the charging power supply can be provided by commercial power according to actual scene requirements, and 220V charging current is output through the positive interface and the negative interface. Charging current is input into the mainboard of the charging equipment through the power input end of the charging equipment directly butted with the charging power supply, and the charging is carried out on the power module in the mainboard. Referring to fig. 1, it can be understood that, when each charging device performs stacked charging, the front end and the rear end of each charging device are sequentially connected in a butt joint manner, wherein the power output end of the previous charging device is connected to the power input end of the next charging device, the power output end of the next charging device is connected to the power input end of the next charging device, and so on, and finally stacked charging of the charging devices is achieved.
Furthermore, when the next charging device needs to be charged, the power input end of the next charging device is connected with the power output end of the previous charging device. The power input anode of the latter charging device is in butt joint with the power output anode of the former charging device, and the power input cathode of the latter charging device is in butt joint with the power output cathode of the former charging device. And when the electrodes of the two charging devices are butted, the rear contact detection point of the former charging device is butted with the front contact detection point of the latter charging device. It should be noted that, after the electrodes of the former and the latter charging devices are butted, the charging current is not directly output to the latter charging device for charging. But the detection of the contact detection point is performed by the main board of the previous charging device. The mainboard of the charging equipment in the embodiment of the application is further in signal connection with the rear contact detection point of the charging equipment and is used for detecting whether the rear contact detection point is in butt joint with the front contact detection points of other charging equipment in real time. When the main board of the former charging device detects that the rear contact detection point is butted with the front contact detection point of the latter charging device, the main board indicates that the power input end of the latter charging device is butted with the rear contact detection point of the former charging device. At this time, the main board of the previous charging device drives the relay connected between the positive electrode of the power input and the negative electrode of the voltage output of the previous charging device to be switched on, so that the charging loop of the next charging device is switched on, and the charging current can be output to the power input end of the next charging device through the power output end of the previous charging device and charges the main board of the next charging device. The front contact detection point and the rear contact detection point for verifying the butt joint of the charging equipment are added, so that the mainboard can know whether the rear-connected charging equipment is connected in real time, and the relay is switched on when the connection is determined, so that the charging loop of the rear-connected charging equipment is switched on. Therefore, the safety problems of circuits such as short circuit of travel equipment and the like under the condition that no charging equipment is connected can be avoided, the safety of superposition charging is improved, and the control of superposition charging of the charging equipment is realized.
For example, in a usage scenario of the intelligent shopping cart, in order to facilitate charging of the intelligent shopping cart, a superposition charging mode of a charging device in the controllable superposition charging system according to the embodiment of the application is adopted to charge the intelligent shopping cart, so as to reduce the setting of a charging power supply interface. When charging, the intelligent shopping cart is stacked together end to end, and the intelligent shopping cart in the forefront is butted with an interface of a charging power supply, so that charging current is input to the mainboard through the power input end of the intelligent shopping cart, and charging of equipment is realized. And then when other intelligent shopping carts need to be charged, the intelligent shopping cart is butted at the back of the frontmost intelligent shopping cart, and the power output end of the previous intelligent shopping cart is butted with the power input end of the rear intelligent shopping cart. And when the butt joint is completed, the relay is controlled to be switched on through the mainboard inside the intelligent shopping cart in front, so that the charging loop of the intelligent shopping cart at the rear is switched on, and the superposition charging of the intelligent shopping cart is realized.
Above-mentioned, through setting up charging source and a plurality of battery charging outfit, battery charging outfit connects gradually, by battery charging outfit output charging current to each battery charging outfit, when battery charging outfit's mainboard detects that corresponding back contact detection point docks with another battery charging outfit's preceding contact detection point, the power input end and the power output end of control corresponding battery charging outfit inside switch on to make charging current output charge to another battery charging outfit. By adopting the technical means, a single charging power supply can charge a plurality of charging devices which are mutually overlapped, and through contact point detection, better charging control of the charging devices is realized, so that the charging safety of the charging devices is guaranteed.
Example two:
fig. 2 is a flowchart of a controllable superposition charging method according to a second embodiment of the present disclosure, where the controllable superposition charging method provided in this embodiment may be implemented by the controllable superposition charging system according to the first embodiment, the controllable superposition charging system may be implemented by software and/or hardware, and the controllable superposition charging system may be formed by two or more physical entities or may be formed by one physical entity.
The following description will be given taking a controllable superposition charging system as an example of an apparatus for performing the controllable superposition charging method. Referring to fig. 2, the controllable superposition charging method specifically includes:
s110, when the mainboard detects that the corresponding rear contact detection point is in butt joint with the front contact detection point of another charging device, controlling the power supply input end and the power supply output end in the corresponding charging device to be conducted so as to enable charging current to be output to the other charging device;
s120, the electric energy input end of the other charging device is connected with a charging current and outputs the charging current to the corresponding main board;
and S130, after the corresponding main board buffers for a set time period, charging current is switched in for charging.
Specifically, when the former charging device performs charging control of the later access charging device, whether other charging devices are accessed is judged by monitoring the level state of the later contact monitoring point of the former charging device through the mainboard in real time. When the main board detects that the level state of the corresponding rear contact detection point is changed from high level to low level, the corresponding rear contact detection point is determined to be in butt joint with the front contact detection point of another charging device, and at the moment, a charging loop of the charging device which is accessed after the charging device is connected can be conducted. It should be noted that when the rear contact detection point of the charging device is suspended, the level state is set to a high level by default. In the application, one end of the front contact detection point of the charging device is grounded, and the level state at the position is low level. When the rear contact detection point of the previous charging device is connected with the front contact detection point of the charging device after being butted, the level state of the rear contact detection point of the previous charging device is pulled down by the front contact detection point of the rear contact detection point of the previous charging device, and the level state of the rear contact detection point of the previous charging device is changed from a high level to a low level. When the mainboard detects the level state change, the internal relay can be driven to conduct a loop of the input anode of the internal power supply and the voltage output anode, so that the charging equipment is connected to the back to start charging.
Further, when charging, the charging current is increased corresponding to the main board according to a set rate until the charging current reaches the charging rated current of the main board, and the charging rated current is the maximum current allowed by safe charging of the main board. Referring to fig. 1, since the charging devices are actually charged in parallel, it is possible to avoid a situation in which the charging circuit is affected by an excessive instantaneous current of a newly connected charging device. When the charging control is performed, the charging current is controlled through the mainboard of the charging equipment. When the charging loop of the charging equipment connected later is turned on, the charging equipment can not quickly charge the mainboard of the charging equipment at once. Instead, after the charging circuit is turned on, the charging current is buffered for a certain period of time, and then the charging current is slowly increased until the maximum charging current expected to be supplied to the charging device is increased. The buffer time and the current increase rate are set according to actual needs, so that the problem of overlarge instantaneous current when several charging devices are charged simultaneously is prevented, and the safety of superposition charging is further improved.
In addition, when a plurality of charging devices are charged, the charging device accessed backwards can be charged through the previous charging device, so that the charging control of the controllable superposition charging system in the embodiment of the application is further optimized. When the corresponding main board of the previous charging device detects that the charging current of the input end of the internal power supply is disconnected, the fact that the charging loop of the current charging device is disconnected with the charging power supply is indicated. In order to ensure that the charging device connected later can continue to charge and can be normally used, a part of computer can be output to the charging device connected later by the corresponding former charging device, and each charging device can be used. At this time, one charging device is requested to output a charging current to an internal power output end so as to charge a main board of another charging device which is connected with the charging device. Further, in order to avoid the situation that the former charging device is in a low power state due to discharging, a power threshold value is preset, and when the internal power is detected to be lower than the set threshold value, the output of the charging current is stopped. With this, the charging equipment can be ensured to share electric energy between the charging equipment through control under the condition that the charging power supply does not supply power, and the charging equipment with more stored electric energy is used as a new charging power supply to charge other electric quantity charging equipment, so that each charging equipment can be normally used, the use of a user cannot be influenced due to low electric quantity, and the use experience of the user is further optimized.
Above-mentioned, through carrying out the on-off control of charging line to each battery charging outfit of butt joint each other, and then realize carrying out stack charging control to battery charging outfit to improve battery charging outfit's security and controllability, avoid the potential safety hazard of charging. Compared with the existing stacked charging system, when stacked charging is carried out, a plurality of charging devices are stacked together for charging, and charging can be carried out as long as the charging devices are connected together in a butt joint mode for convenience of operation. And when charging, because a plurality of charging devices stack and charge, charging power can be great relatively, appears charging potential safety hazard easily. Therefore, the controllable overlapping charging method provided by the embodiment of the application is provided to solve the technical problems that an existing overlapping charging system is uncontrollable and has potential safety hazards.

the output module 32 is used for accessing a charging current through an electric energy input end of another charging device and outputting the charging current to a corresponding main board;
the charging module 33 is used for charging by accessing a charging current after a corresponding time period is set by the main board buffer.
Above-mentioned, through carrying out the on-off control of charging line to each battery charging outfit of butt joint each other, and then realize carrying out stack charging control to battery charging outfit to improve battery charging outfit's security and controllability, avoid the potential safety hazard of charging. Compared with the existing stacked charging system, when stacked charging is carried out, a plurality of charging devices are stacked together for charging, and charging can be carried out as long as the charging devices are connected together in a butt joint mode for convenience of operation.
