Description
POWER SUPPLY SYSTEM FOR AN INDUSTRIAL VEHICLES
Technical Field
The present invention relates to a power supply system of industrial vehicles. Background Art
A variety of power supply systems are known to be mounted on respective vehicles to enable their power supply and consequently their operation.
Typically, such systems employ lithium batteries that are periodically charged so that the vehicle can run for long duty cycles before charging the battery.
This type of systems does however have some drawbacks related to the proper use of the lithium battery.
In fact, it is well known that the use of lithium batteries, and therefore also of the industrial vehicle on which they are mounted, must comply with some fundamental directions in order to preserve the soundness of the entire system.
In particular, the electrical charge stored inside such batteries must not drop below a critical level that jeopardizes the soundness of the battery.
It happens very frequently, however, that the industrial vehicles on which these batteries are fitted, are stopped for long periods of time without worrying about the state of charge thereof, for example at the end of a working day.
Therefore, the batteries of known type make use of appropriate management/control means, the so-called BMS (Battery Management System), which aim to isolate the battery from the rest of the system after a guard charge level has been reached, so as to prevent the battery charge from dropping below the critical level.
However, after having isolated the battery, the industrial vehicle cannot be started normally; the vehicle, in fact, must undergo lengthy reset operations of the system aiming at starting the vehicle safely, in this case, carrying out all the safety checks necessary to verify the soundness of the battery. These checks are essential to avoid battery malfunctions and breakages that can also cause explosions and/or fires.
These drawbacks significantly reduce the time of use of the industrial vehicle due to the long start-up time caused by the reset operations. Therefore, it
frequently happens that such vehicles are tampered with to bypass safe reset operations and start the vehicle immediately.
This additional drawback jeopardizes the safety of personnel operating the vehicle and the entire course of activities involving it.
Description of the Invention
The main aim of the present invention is to devise a power supply system of industrial vehicles that allows the system to be safely deactivated, while preserving the soundness of the battery itself.
Another object of the present invention is to devise a power supply system of industrial vehicles that allows the system and the vehicle to be safely activated in a safe, easy and quick manner.
An additional object of the present invention is to devise a power supply system of industrial vehicles that allows the system and vehicle to be safely activated without the need to initiate any battery status check operation.
Another object of the present invention is to devise a power supply system of industrial vehicles which allows overcoming the aforementioned drawbacks of the prior art within a simple, rational, easy, effective to use and low cost solution.
The objects set out above are achieved by the present power supply system of industrial vehicles having the characteristics of claim 1.
The objects set out above are achieved by the present machine having the characteristics of claim 10.
Brief Description of the Drawings
Other characteristics and advantages of the present invention will become more apparent from the description of a preferred, but not exclusive, embodiment of a power supply system of industrial vehicles, illustrated by way of an indicative, yet non-limiting example, in the accompanying tables of drawings wherein: Figure 1 is a schematic view of the system according to the invention;
Figure 2 is an axonometric view of the machine according to the invention.
Embodiments of the Invention
With particular reference to such figures, reference numeral 1 globally indicates
a power supply system of industrial vehicles.
The power supply system 1 of industrial vehicles comprises at least one lithium power supply unit 15 mounted on an industrial vehicle 4 and provided with: at least one row of lithium cells 2 configured to power the system itself and the industrial vehicle 4; management/control means 3 of the same power supply unit.
Preferably, the row of cells 2 is provided with a plurality of lithium cells electrically connected to each other in series and/or in parallel, so as to substantially define a lithium power supply source.
On the other hand, the management/control means 3 are preferably of the type of a BMS (Battery Management System) operatively connected to the row of cells 2, so as to substantially make a lithium battery.
Conveniently, the system 1 comprises on/off switching means 7 for switching on/off the system itself safely, which are operatively connected positioned between the row of cells 2 and the management/control means 3 and configured to activate/deactivate the system 1 respectively, in at least one configuration of use, wherein the row of cells 2 powers the system 1 , thus allowing it to operate, and in at least one home configuration, wherein the row of cells 2 does not power the management/control means 3, but it powers the on/off switching means 7, so as to allow the activation of the system 1 again in the safe configuration of use.
Preferably, in the home configuration, the row of cells 2 powers only the on/off switching means 7.
In addition, preferably, the system 1 comprises power distribution means, not shown in the figures, and configured to distribute the power supplied by the row of cells 2. In particular, the power distribution means are controlled by at least one of either the management/control means 3 or the on/off switching means 7 and are preferably of the type of an electrical circuit controllable to distribute the power supplied by the row of cells 2.
The on/off switching means 7 are preferably of the type of an electronic device configured to exchange the signals with one or more components of the system
1.
Advantageously, in the configuration of use, the management/control means 3 are configured to control the on/off switching means 7, by deactivating the system 1 in the home configuration when the charge value of the row of cells 2 is substantially less than a reference critical charge value.
Preferably, the critical charge value is a charge value characteristic of the row of cells 2 that defines the residual charge useful to safely preserve the soundness thereof for a long time.
In fact, the management/control means 3 are configured to detect the charge of the row of cells 2.
In this manner, the management/control means 3 are configured to compare the charge value of the row of cells 2 with the reference critical charge value, and to control the on/off switching means 7 to deactivate the system 1 in the home configuration when the charge value of the row of cells 2 is found to be substantially less than or equal to the reference critical charge value.
In particular, the electrical charge consumption of the row of cells 2 powering the on/off switching means 7 is substantially less than the electrical charge consumption of the row of cells 2 powering the management/control means 3.
In other words, the electrical charge consumption of the row of cells 2 in the configuration of use, i.e., when the row of cells 2 powers the management/control means 3, is higher than in the home configuration, i.e., when the row of cells powers the on/off switching means 7.
In fact, the electrical power needed by the on/off switching means 7 for their operation is substantially less than that required by the management/control means 3.
Therefore, the system 1 can remain in the home configuration for long periods of time while ensuring the soundness of the row of cells 2; in fact, in this configuration, the row of cells 2 maintains a substantially constant charge value over time (with reference to normal usage cycles of the system in the work configuration and in the idle configuration).
This solution dramatically reduces the risk of the row of cells 2 reaching a
dangerous level of charge that could jeopardize the soundness of the row itself, thus ensuring that the system 1 can always be safely activated/deactivated quickly and easily.
In this way, the system 1 is activated again in the configuration of use without the need to perform any prior safe reset operations of the system.
Conveniently, the system 1 comprises at least one activation device 5 configured to control the on/off switching means 7 and usable by a user to activate the system 1 in the configuration of use.
Preferably, the activation device 5 is of the type of an electronic switch configured to send one or more control signals to the on/off switching means 7. Conveniently, the activation device 5 is usable by a user to deactivate the system in the home configuration.
In this way, the activation device 5 is configured to deactivate the system 1 in the home configuration regardless of the management/control means 3.
In other words, the activation device 5 is employed by the user to safely switch the system 1 on/off.
Conveniently, the power supply unit 15 comprises the on/off switching means 7.
In particular, the power supply unit 15 coincides with a lithium battery 6.
In other words, the row of lithium cells 2, the management/control means 3, and the on/off switching means 7 are integrated with each other into a single body piece defining the lithium battery 6.
The present invention relates to an industrial machine 9 comprising:
- at least one system 1 as described above;
- the industrial vehicle 4.
In particular, the industrial vehicle 4 is started/stopped in the configuration of use and in the home configuration, respectively.
Advantageously, the machine 9 comprises starting/stopping means 8 of the industrial vehicle 4, configured to start/stop the movement thereof and coinciding with the activation device 5.
In other words, the starting means 8 are of the type of known starting means,
such as e.g. a starting unit of the engine of the industrial vehicle 4 or the like.
Thus, the activation/deactivation of the system 1 coincides with the start/stop of the vehicle 4. Therefore, the system 1 and/or the machine 9 do not need two systems which are separate from each other in order to activate/deactivate the system 1 and to start/stop the vehicle.
It has in practice been ascertained that the described invention achieves the intended objects.
In particular, the on/off switching means allow the system and the industrial vehicle itself to be safely deactivated without jeopardizing the soundness of the row of cells.
Similarly, the on/off switching means allow the system and the industrial vehicle to be activated safely, easily and quickly without the need for any reset operations of the system.
Furthermore, the on/off switching means allow the system to be activated/deactivated at the same time as the start/stop of the industrial vehicle in a quick and easy way.
