Description

Technical Field

[0001] The invention relates to the field of industrial vehicle design and manufacturing, and in particular to an industrial vehicle battery scheduled charging control system. Background Art

[0002] Industrial vehicles refer to power-driven motor vehicles used to transport, push, pull, lift, stack or stack various goods. They are an important branch of engineering machinery and one of the important equipment in the logistics industry. They mainly include forklifts, tractors, transporters, etc. With the widespread application of new energy technologies, the travel drive of existing industrial vehicles and the actions of some actuators are powered by electricity, that is, the batteries on the industrial vehicles are used to power the above actions.

[0003] In one construction area or multiple construction areas in different regions, there are many numbers and types of industrial vehicles involved in the operation. Moreover, different industrial vehicles have different battery capacities and large differences in endurance. Therefore, the charging needs of industrial vehicles are generally diverse and complex. If the above charging needs cannot be met, the effective dispatch rate of the vehicle will be greatly reduced, resulting in waste of resources and slowing down the construction progress.

[0004] In the prior art, there are means of scheduled charging, which can enable the vehicle to charge at a fixed time or in a fixed quantity under the premise of connecting the charging gun, thereby rationally utilizing the charging resources and improving the effective dispatch rate of the vehicle. Applying this means of scheduled charging to the charging of industrial vehicles can solve the problem of low effective dispatch rate of industrial vehicles. In the prior art, most of the new energy household vehicles that are widely accepted by the public are equipped with high-voltage systems, such as EV high-voltage systems, PHEV high-voltage systems, etc., which use the BMS battery management system to realize the scheduled control of vehicle battery charging, such as using a mobile phone APP to perform the appointment operation.

[0005] However, the reservation charging function of existing new energy household vehicles is usually limited to one-to-one short-distance control, and cannot achieve centralized reservation charging control in a large area, so it is difficult to directly apply it to industrial vehicles. Summary of the invention

[0006] The purpose of the present invention is to provide an industrial vehicle battery scheduled charging control system, which can realize large-area centralized scheduled charging control of industrial vehicles in complex environments, thereby improving the overall effective scheduling rate of industrial vehicles.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: An industrial vehicle battery scheduled charging control system, characterized in that the system comprises: A battery to be managed, the battery to be managed comprising a battery cell module, a first communication unit and a battery management unit connected to the battery cell module, the battery management unit being used to receive a control command from the first communication unit and perform charging control on the battery cell module; a remote management module, the remote management module comprising a second communication unit for transmitting and receiving data with the first communication unit, a processing unit connected to the second communication unit, and a display operation unit connected to the processing unit; A charging device, which can be plugged in and connected to the battery to be managed, and is used to replenish electric energy for the battery module.

[0008] The industrial vehicle battery reservation charging control system includes a battery to be managed, a remote management module and a charging device.

[0009] The battery to be managed is installed on different industrial vehicles, which have a built-in battery management unit and a first communication unit, and the first communication unit is specifically a first wireless data transceiver. The battery management unit obtains the real-time voltage, current, temperature and other status data of the battery module, and the battery management unit has a built-in timer that can calculate the system time by itself.

[0010] The remote management module includes a second communication unit for transmitting and receiving data with the first communication unit. The second communication unit is specifically a second wireless data transceiver, which can transmit the data sent by the first communication unit to the processing unit, and the processing unit converts and sends the data to the display operation unit. The user can remotely schedule charging, change scheduled charging, and cancel scheduled charging through the display operation unit. These instruction information are transmitted to the second communication unit through the processing unit, and sent to the first communication unit, and the first communication unit then transmits it to the battery management unit.

[0011] Regardless of whether the battery to be managed is connected to the charging device, as long as the battery management unit and the first communication unit are online, remote charging reservation, charging reservation change and charging reservation cancellation can be directly performed.

[0012] As a preferred embodiment of the present invention, a heartbeat detection mechanism is provided between the processing unit and the battery management unit, and the heartbeat detection mechanism is used to determine whether the battery management unit is online.

[0013] When the industrial vehicle is in the starting state, that is, when the battery management unit in the battery to be managed thereon is in the powered state, the battery management unit is online, and it has the ability to manage the charge and discharge of the battery cell module or monitor other data. When it is online, it will communicate the heartbeat signal with the processing unit through the first communication unit and the second communication unit, so that the processing unit can send a scheduled charging command to the battery management unit. After receiving the scheduled charging command, the battery management unit feeds back a result command to the processing unit, and the processing unit sends it to the display operation unit for display to inform the operator of the appointment result.

[0014] As a preferred embodiment of the present invention, the remote management module also includes a cache unit.

[0017] As a preferred embodiment of the present invention, the processing unit receives an operation command sent by the display operation unit, and calculates a countdown time according to the operation command; when the countdown time returns to zero, a charge start command is sent to the battery management unit.

[0018] As a preferred embodiment of the present invention, the countdown time is calculated as follows: T=t1-t2 Wherein, T is the countdown time; t1 is the set local charging start time; t2 is the current local time.

[0019] As a preferred embodiment of the present invention, the countdown time is calculated as follows: T=Ta-Tb Among them, T is the countdown time; Ta is the set countdown duration; Tb is the timer timing duration.

[0025] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0026] The terms "first", "second", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any variation thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0027] Unlike new energy vehicles, industrial vehicle batteries provide power for controllers, drive motors, pump station motors, sound and light devices, and do not have start-stop batteries. The built-in battery management system and communication unit will enter a deep sleep state after a long period of standby or when the vehicle key is turned off, and cannot be online in real time.

[0028] like Figure 1 As shown, the industrial vehicle battery reservation charging control system includes a battery to be managed, a remote management module and a charging device. The battery management unit is used to receive the control command of the first communication unit and control the charging of the battery module, and it includes a battery module, a first communication unit, a battery management unit connected to the two at the same time, and a positioning unit. The remote management module includes a second communication unit for sending and receiving data with the first communication unit, a processing unit connected to the second communication unit, a display operation unit connected to the processing unit, and a cache unit, and a cancellation timer is also provided in the cache unit. The charging device is pluggable and connected to the battery to be managed, and is used to replenish power for the battery module; a connection sensor is provided between the charging device and the battery to be managed; the specific induction form adopted by the connection sensor includes photoelectric induction, ultrasonic induction or electromagnetic induction.

[0029] The battery to be managed is installed on different industrial vehicles, which have a built-in battery management unit and a first communication unit, and the first communication unit is specifically a first wireless data transceiver. The battery management unit obtains the real-time voltage, current, temperature and other status data of the battery module, and the battery management unit has a built-in timer that can calculate the system time by itself.

[0030] The remote management module includes a second communication unit for transmitting and receiving data with the first communication unit. The second communication unit is specifically a second wireless data transceiver, which can transmit the data sent by the first communication unit to the processing unit, and the processing unit converts and sends the data to the display operation unit. The user can remotely schedule charging, change scheduled charging, and cancel scheduled charging through the display operation unit. These instruction information are transmitted to the second communication unit through the processing unit, and sent to the first communication unit, and the first communication unit then transmits it to the battery management unit.

[0031] Regardless of whether the battery to be managed is connected to the charging device, as long as the battery management unit and the first communication unit are online, remote charging reservation, charging reservation change and charging reservation cancellation can be directly performed.

[0032] In a possible embodiment, Figure 2As shown, the processing unit actively obtains the heartbeat signal of the battery management unit through the second communication unit. If the battery management unit and the first communication unit are online, and the processing unit can obtain a valid heartbeat signal of the battery management unit, it is determined that the battery management unit is online and can directly perform scheduled charging, change pre-charging, and cancel scheduled charging.

[0033] The user operates the display operation unit to schedule charging, change pre-charging and cancel scheduled charging, and the control command is wirelessly transmitted to the second communication unit and the battery management unit through the processing unit and the second communication unit; if the battery management unit successfully receives the corresponding control command for scheduling charging, changing pre-charging and canceling scheduled charging, a result command is fed back to the processing unit, and the processing unit sends it to the display operation unit for display to inform the operator of the scheduling result.

[0034] When the battery management unit of the target communication is not online (the industrial vehicle is shut down), the processing unit sends the control command to the cache unit for temporary storage; the temporarily stored command is a message queue; since a cancel timer is provided in the cache unit, and a cancel value is set in the cancel timer; if the above-mentioned battery management unit is not online within the time length corresponding to the cancellation value, the cache unit deletes the temporarily stored message queue; if the above-mentioned battery management unit is back online within the time length corresponding to the cancellation value, the cache unit sends the commands in the message queue to the battery management unit in chronological order through the second communication unit. At this time, the battery management unit also feeds back a result command to the processing unit, and the processing unit sends it to the display operation unit for display to inform the operator of the appointment result.

[0035] In another possible embodiment, for the timed scheduled charging mode, the user needs to set the local charging start time t1 on the display operation unit. The local here is defined for the location A where the industrial vehicle is located, that is, the industrial vehicle is located at location A, and the remote management module is located at location B. Location A and location B can be in the same time zone or in different time zones. When location A and location B are in different time zones, it involves the large-area scheduled charging control in the present invention. Since the battery to be managed includes a positioning unit, the coordinate position of the battery to be managed can be obtained with the help of the positioning unit, and the coordinate position can be sent to the processing unit through the first communication unit and the second communication unit; the processing unit can obtain the local time of the battery to be managed according to the coordinate position, that is, obtain the local time of location A.

[0036] The processing unit receives the operation command sent by the display operation unit, and calculates the countdown time according to the operation command; the countdown time T = the set local start charging time t1-the current local time t2; wherein the current local time t2 is obtained by the above-mentioned processing unit, and the set local start charging time t1 is set by the user. Through the above-mentioned means, the user can simply set the charging time point without additionally calculating the forward or reverse time difference caused by the cross-time zone, thereby simplifying the operation process; since the current local time t2 will change with the passage of time, when it is completely equal to the set local start charging time t1 in time value, the countdown time T is 0, and at this time the processing unit sends the start charging command to the corresponding battery to be managed through the first communication unit and the second communication unit. At this time, the battery management unit obtains the output status of the connection sensor between the battery management unit and the charging device, and if the status output by the connection sensor is connected, charging starts.

[0037] In another possible embodiment, for the countdown scheduled charging mode, the user needs to set the countdown duration Ta on the display operation unit. At this time, since the battery to be managed has a timer when it leaves the factory, when the countdown scheduled charging mode is turned on, the timer starts counting, and the timer timing duration Tb increases from 0. When the timer timing duration Tb is equal to the set countdown duration Ta, the countdown time T is 0. At this time, the processing unit sends a start charging command to the corresponding battery to be managed through the first communication unit and the second communication unit. At this time, the battery management unit obtains the output status of the connection sensor between the battery management unit and the charging device. If the status output by the connection sensor is connected, charging starts.

[0038] In another possible embodiment, for the quantitative charging mode, the user needs to set the charging target amount on the display operation unit. At this time, the processing unit sends a start charging command to the corresponding battery to be managed through the first communication unit and the second communication unit. At this time, the battery management unit obtains the output status of the connection sensor between the battery management unit and the charging device. If the status of the connection sensor output is connected, charging starts. When the battery management unit detects that the lighting of the charging cell reaches the above-mentioned charging target amount, charging stops.

[0039] In the present invention, the first communication unit and the second communication unit are specifically wireless data transceiver devices, which can be data transceiver devices supporting WIFI, 4G, 5G wireless networks or other long-wave communications, and wirelessly transmit control commands and data between the remote management module and the battery to be managed with the help of satellites or cross-regional transit base stations.

[0040] In addition, each industrial vehicle comes with a timer when it leaves the factory, which is used to provide a timing basis for calculating the countdown time T in the countdown appointment charging mode.

[0041] In addition, a connection sensor is provided between the charging device and the battery to be managed. The specific sensing forms adopted by the connection sensor include photoelectric sensing, ultrasonic sensing or electromagnetic induction.
