Description

LITHIUM POWER SUPPLY BOX

Technical field of the Invention

The present inventive concept relates to a lithium power supply box. Background of the Invention Lithium power supplies (LPS) are commonly used in many different fields where one needs off grid power. However, typical LPS are heavy and clunky. Therefore, it may be cumbersome for a user to move an LPS, which may result in the LPS being securely fastened to a rack or similar fastening or suspending means. If the moving of an LPS is hard, or inaccessible, then the potential uses are diminished. Further, some devices which may need an LPS to be powered may be hard to reach or access without moving the LPS.

However, when an LPS is not in use by a user, it is often stored in a limited space or transported in a service vehicle. The space for storage of the LPS along with auxiliary devices, to be powered by the LPS, is often limited. It is therefore an issue of how to logistically provide and supply an LPS which is movable and storable. Further, the storing and moving of auxiliary devices may also be an issue.

The present inventive concept seeks to provide an LPS which is more flexible to use, for instance regarding storage, transportation, and accessibility than the mentioned prior art LPS.

Summary of the Invention

An object of the inventive concept is to mitigate the above problems, and to provide a lithium power supply box which, at least to some extent, is movable and modular. This, and other objects, which will become apparent in the following, are accomplished by means of a lithium power supply box defined in the accompanying claims.

The present inventive concept is based on the insight that a lithium power supply may be divided into multiple modular parts. According to at least a first aspect of the present inventive concept, a portable lithium power supply box is provided. The portable lithium power supply box comprises: a container; a cover; wherein the cover and the container are each provided with attaching means, adapted to attach the cover to the container; a battery module arranged inside the container; a modularised unit; at least one electrical connection, adapted to electrically connect the container and the cover; at least one power output; at least one charging input.

In one example embodiment, the at least one power output may comprise at least one of a 230V output and a 12V output.

The at least one power outlet may be configured as a USB socket. Further, the at least one charging input may comprise at least one of a 230V input and a 12V input. The portable lithium power supply box may comprise at least one socket configured as a power output and a charging input. The at least one power output may comprise a plethora of different voltage outputs. The portable lithium power supply box may be configured to comprise any number of different combinations of output sockets.

In another example embodiment, the at least one electrical connection may be adapted to electrically connect the container and the cover when the cover rests as a lid on the container.

The electrical connection may comprise at least one connection socket on the container and on the cover, which may be adapted to electrically connect the container and the cover. The electrical connection may comprise a connection means, such as a cable, which may be arranged on the container or the cover. The connection means and the connection socket may be adapted to electrically connect the container and the cover. Further, the electrical connection may comprise at least two connection sockets on the container and on the cover. The at least two connection sockets may be configured to be connected by a connection means, such as a cable. The electrical connection may be electrically connected when the cover is in contact with, or abutting and/or fastened to the container. The cover may be configured to rest as a lid on the container, which may be pivotally arranged on the container. The electrical connection may be adapted to connect the container and the cover the cover rests as a pivotally arranged lid on the container. The electrical connection creates the possibility to pair different kinds of covers to different kinds of containers. Thereby the size of the portable lithium power supply box may be optimized for the intended use. Further, the possibility of pairing different kinds of covers to different kinds of containers may be optimized with regards to the modularized unit and/or auxiliary devices, to be used with the portable lithium power supply box. Further, the portable lithium power supply box may be more flexible to use, for instance regarding storage, transportation, and accessibility.

According to at least one example embodiment, the at least one electrical connection may be adapted to electrically connect the container and the cover or a second container.

The attaching means may be adapted to attach a container to a second container. The portable lithium power supply box may be configured to be stackable, such that at least two containers may be attached on top of each other. The containers may be controlled by a battery management system e.g in a master-slave control set up. Further, the electrical connection may electrically connect at least two containers. The portable lithium power supply box may comprise a first container, a cover and a second container. The portable lithium power supply box may comprise at least two containers and a cover. The modularity of the portable lithium power supply box makes it more flexible to use. The option to attach additional containers to the portable lithium power supply box may increase the battery capacity, or it may make it possible to add additional features. Further, it may make it easier to store, transport or access the portable lithium power supply box. Additionally, it may be possible to supply electricity continuously, by switching containers containing depleted batteries to containers containing charged batteries, which may increase the uptime and/or the efficiency of the apparatus.

Alternatively a portable lithium power supply box may be connected to at least a second portable lithium power supply box. The boxes may be controlled by a battery management system e.g in a master-slave control set up.

The batteries may be connected in parallel, thus increasing the amperage. In one example embodiment, the modularised unit may comprise as selected from the group of a charger module, an inverter module or a charger/inverter module.

The modularised unit may be arranged in the cover or the container, or in the cover and the container. The battery module may further comprise as selected from the group of a charger module, an inverter module or a charger/inverter module. The portable lithium power supply box may comprise a charger module and an inverter module or a charger/inverter module, which may be arranged in the modularised unit, the battery module or the battery module and the modularised unit. The possibility of having a charger module, an inverter module or a charger/inverter module in either of the cover and container increases the flexibility of the apparatus. For example, a container comprising a battery module comprising a charger module may be attached to a cover comprising a modularised unit comprising an inverter module. Another example is a container comprising a battery module which may be attached to a cover comprising modularised unit comprising a charger/inverter module. A second container comprising a battery module may be attached to a portable lithium power supply box comprising a modularised unit comprising either a charger module and an inverter module, or a charger/inverter module. Thereby, increasing the battery capacity of the portable lithium power supply box.

In another example embodiment, the modularised unit may comprise a heater module.

The heater module may be comprised in the container or the cover, preferably in the cover. The heater unit may comprise at least one fan.

Further, the heater unit may comprise at least one air outlet. The at least one air outlet may be arranged on the top of the cover. A portable lithium power supply box comprising a heater module may allow for heating of a space or area, such as the inside of a service vehicle. The heater module may increase the temperature of a space or area, even while at remote locations. Fleating of a space or area, may make it possible for a user to work in said space or area. When heating a service vehicle with the heater module, it may replace the use of the heating system of the service vehicle, which may run on fossil fuels. Therefore, the heater module may reduce the environmental impact of heating a service vehicle.

According to at least one example embodiment, the modularised unit may comprise a light, such as a spotlight, a headlight, a warning light or a traffic light.

The portable lithium power supply box may be configured for attachment of a light. The portable lithium power supply box may act as a base for a light, improving the stability of the light and the safety of using the light. The light may be contained in the portable lithium power supply box when not in use. The light may be attached on top of the portable lithium power supply box. The light may be connected to one of the at least one power outputs. The portable lithium power supply box may comprise any number of lights, such as one, two, three, four or five.

In one example embodiment, the portable lithium power supply box may be configured to be chargeable in a vehicle.

The portable lithium power supply box may be further configured to be chargeable while said vehicle is running. Thereby, the portable lithium power supply box may be charged during travel, which may increase the uptime for a user. Further, the portable lithium power supply box may be further configured to be chargeable while said vehicle is not running. Thereby, if the user needs power at a location inaccessible to said vehicle, the user could take the portable lithium power supply box to the location. If the battery module runs out, then the user may charge it in said vehicle, even though the vehicle is not running. Thereby increasing the reliability of the portable lithium power supply box. Additionally, if said vehicle is an electric vehicle the portable lithium power supply box may be configured to be chargeable while the electric vehicle is charging. The charging in an electric vehicle may be sequential charging, such that the charging of the portable lithium power supply box starts when the charging of the electric vehicle is finished, or that the charging of the electric vehicle starts when the charging of the portable lithium power supply box is finished. However, the moment of switching between charging the portable lithium power supply box and the electric vehicle is not limited to the moment when one device is fully charged. A schedule could be used. For example, the electric vehicle may be charged up to 80% of its capacity, then the portable lithium power supply box may be charged up to 80%, then the vehicle may be charged up to 100%, and then the portable lithium power supply box may be charged to 100%. The charging schedule is not limited to the above example. The values of switching between the electric vehicle and the portable lithium power supply box may be 50%, 60%, 70%, 80% or 90%. Sequential charging of the portable lithium power supply box may make sure that the greatest power needs are supplied first, which may increase the efficiency. Additionally, the charging in an electric vehicle may be parallel charging, such that the charging of the portable lithium power supply box is done simultaneously as the charging of the electric vehicle. This may reduce the charging time, which increases the efficiency of the device. The batteries may be controlled by a battery management system e.g in a master-slave control set up.

In another example embodiment, the cover may be usable as a removable cover. The cover may be enabled to rest as a lid on the container. Further, the cover may be configured as a pivotable cover by pivotally connecting the said attaching means of the cover to the attaching means of the container.

Thereby, a service technician may separate the cover and the container and gain access to interior components of the portable lithium power supply box. Gaining access to the interior components may allow a use to repair or replace components, which may increase the lifetime of the portable lithium power supply box or increase the possible areas of use. Further, a first cover usable as a removable cover may allow a user to switch the cover to a second removable cover. The second removable cover may comprise different parts, such as a modularised unit comprising different parts than the modularised unit of the first removable cover. The removability of the cover therefore increases the modularity of the portable lithium power supply box, thereby providing a portable lithium power supply box that is more flexible to use.

According to one example embodiment, the container may comprise at least one hand grip. The cover may comprise one hand grip. The hand grips may be configured such that when said cover is secured or connected to said container, a user may carry or pull said portable lithium power supply box by the hand grip of the container or by the hand grip of the cover.

Further, the hand grips may be configured such that a user may carry or pull said portable lithium power supply box by the hand grip of the container. The hand grip may make the portable lithium power supply box easier to move, which may help during transportation and storage, thereby making the portable lithium power supply box more flexible to use.

In one example embodiment the portable lithium power supply box may be adapted to be removably attachable. Further, the portable lithium power supply box may be adapted to be removably attachable to a cart and/or a rack, such as a vehicle rack.

The attaching means may be adapted to removably attach the cover to the container. Further, the attaching means may be adapted to removably attach the portable lithium power supply box to a cart and/or a rack, such as a vehicle rack. Attaching the portable lithium power supply box to a cart or rack may make it easier to store and/or transport the portable lithium power supply box, thereby providing a portable lithium power supply box which is more flexible to use. Being able to removably attach the portable lithium power supply box to a cart and/or a rack, such as a vehicle rack, may increase the security when transporting the portable lithium power supply box.

According to one example embodiment, the portable lithium power supply box may further comprise a pivot axle. Further, the cover may also be usable as a pivotable cover by pivotally connecting one of said first receiving portions to a mating one of said second receiving portions by means of said pivot axle.

Thereby the opening and closing of the pivotable cover is easier to do. Further, the rigidness of the portable lithium power supply box may be increased.

In another example embodiment, the modularised unit may be arranged inside the cover.

The container, which has the battery module arranged inside, may be paired with a cover. A modularised unit arranged in the cover may allow for differently configured covers, due to differences between the modularised units. Therefore, during production of portable lithium power supply boxes, there may be possible to produce a wide variety of portable lithium power supply boxes by producing multiple kinds of covers and pairing them with a container, chosen from a smaller collection than the collection of potential covers. Thereby, the production cost and time of different kinds of portable lithium power supply boxes may be reduced. Further, the number of possible kinds of portable lithium power supply boxes may be increased. Therefore, a user may receive a portable lithium power supply box more precisely fit to its needs.

According to at least one example embodiment, the attaching means may be configured as first receiving portions provided on the cover and as second receiving portions provided on the container.

The attaching means may further comprise eccentric locks. The eccentric locks may be adapted to connect the first receiving portions and the second receiving portions, thereby attaching the container to the cover. The structural stability of the portable lithium power supply box may be increased by the use of first and second receiving portions. The structural stability of the portable lithium power supply box may be further increased by the use of eccentric locks.

In one example embodiment, the portable lithium power supply box may be adapted to be controllable by a remote handheld device, such as a phone or a tablet.

A remote handheld device, such as a phone or a tablet, may control the charging and/or the output levels of the portable lithium power supply box. Further, a remote handheld device, such as a phone or a tablet, may monitor the charging and/or output levels of the portable lithium power supply box. Flaving access to the current status of the charging and/or output may help a user plan their future use of the portable lithium power supply box, thereby increasing the efficiency for the user. Further, a user may start the charging of the portable lithium power supply box remotely, thereby saving time for the user. In another example embodiment, the portable lithium power supply box may be configured to be chargeable from a wall socket.

The at least one charging input may be connected to a wall socket, such that the portable lithium power supply box is charged. Charging the portable lithium power supply box from a wall socket may ensure that the portable lithium power supply box is charged by clean energy, reducing the environmental impact of the portable lithium power supply box. Further, by charging the portable lithium power supply box from a wall socket, the user may bring and charge the portable lithium power supply box with him/her to any place which has wall sockets. For example, the user could then charge the portable lithium power supply box while on a break and return to work with a recharged portable lithium power supply box. Thereby increasing the potential uptime of the portable lithium power supply box.

In one example embodiment, the outputs and inputs are arranged on the cover. Flowever, the outputs and inputs may be arranged on the container. Further, the outputs may be arranged on the cover, while the inputs may be arranged on the container. Contrastingly, the outputs may be arranged on the container, while the inputs may be arranged on the cover. Providing inputs and/or outputs on the cover and/or the container provides a portable lithium power supply box that is more flexible to use.

In one example embodiment, the portable lithium power supply box has a weight of 15 to 30 kg, preferably 20 to 30 kg, and more preferably 25 to 30 kg.

A portable lithium power supply box that has a weight of 15 to 30 kg, preferably 20 to 30 kg, and more preferably 25 to 30 kg, makes it possible for a user to carry at least one portable lithium power supply box. Thereby, a portable lithium power supply box which is easier to store and transport is provided. Further, with a weight of 15 to 30 kg, preferably 20 to 30 kg, and more preferably 25 to 30 kg, a user may easily removably attach at least one portable lithium power supply box to a cart and/or rack.

In one example embodiment, the battery module comprises a battery with a capacity of 70 to 200Ah, preferably 80 to 200Ah, and more preferably 100 to 200Ah. Thereby, a battery module is provided that is more flexible to use due to a high capacity. The capacity of 70 to 200Ah, preferably 80 to 200Ah, and more preferably 100 to 200Ah enables a user to utilize the portable lithium power supply box longer between charges, thereby increasing efficiency.

In another example embodiment the cover and the container are comprised of thermoplastic. The cover and the container may be formed by injection molding. The weight of the cover and the container is therefore low, providing a portable lithium power supply box that is easier to carry, store and transport, which may increase the ease and efficiency of use, for a user. Further, the material may increase the durability of the portable lithium power supply box.

According to an example embodiment, the battery module comprises at least one lithium-ion battery.
