Description

DESCRIPTION

AUXILIARY QUICK MAINTENANCE BOX FOR BATTERIES

TECHNICAL SECTOR

The present invention belongs to the field of technology, and more specifically to the field of electric batteries.

The object of the present invention is a new rapid maintenance auxiliary box for batteries that centralizes all the electronics together with the electrical connection protections and is specially designed to facilitate maintenance tasks on electric batteries and consequently reduce the risks associated with the exposure to high voltage and repair and maintenance times.

BACKGROUND OF THE INVENTION

Currently, batteries for electric and hybrid vehicles present two problems:

The first of these is the large amount of time invested in ensuring the absence of tension to be able to work safely and the risk that these verification operations can sometimes pose.

Second, many of the maintenance or repair interventions involve removing the battery from the vehicle, increasing intervention times and associated costs.

These batteries incorporate all the electronics distributed within the main battery box itself. This electronics found in the battery pack is usually made up of the electronic boards in charge of communication between the different components, those of the cell balancing system, those of module control, etc. To repair any component of them, you must remove the battery from the vehicle or compartment in which it is located and carry out the repair by removing the entire battery.

Currently there is no battery designed in such a way that it is not necessary to remove said battery from the place where it is housed to carry out repairs and / or maintenance on the electronics.

EXPLANATION OF THE INVENTION

The inventor of the present application has developed a new system that solves the above problems thanks to the modification of the arrangement of the battery cells already known in the art.

The batteries designed to date are equipped with an external structure that covers all the contents of said battery, both cells and electronic components. This arrangement makes it impossible to carry out repairs to the battery electronics without having to remove the battery from its housing.

The inventor of the present application has designed a new auxiliary box that houses, together with the electrical connection protections, all the battery electronics, centrally and outside the main box. This box is adjacent to the main box that houses all battery cells and modules. Fundamentally, the main modification consists of extracting all the battery electronics from inside the main battery box where the cells are also located and attaching it to the outside of said main box by means of a second auxiliary box with a smaller cover. This modification allows easy maintenance of all battery electronics without having to remove said battery from the site where it is located and thus reduce repair and maintenance times and costs.

In accordance with all of the above, the present invention is directed to a battery box that fundamentally comprises a main box and an auxiliary box with a cover. Each of these parts are defined in more detail below:

a) The main box preferably comprises an essentially cuboid shape that integrates the entire set of battery cells, as well as cooling and sensors that report to the external electronics.

b) The auxiliary box preferably comprises an essentially cuboid shape that it is attached to one of the outer side walls of the main box. Said auxiliary box consists of a cover, housed in the outermost part of the contact wall between both boxes, which is fundamentally the one that allows easy accessibility to all the internal components of the auxiliary box. The outer face of the main box to which said auxiliary box is attached will preferably be any that by design is best accessible at the final location of the entire battery assembly for maintenance or repairs.

In addition, it is understood that between the main box and the auxiliary box there is a cutout or hole that connects both boxes on the inside and that, consequently, allows the passage of wiring and other components inside.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, in which, with an illustrative and non-limiting nature, the following has been represented. following:

Figure 1 shows an isometric view of a battery, with a main box with its cover, together with an auxiliary box and the cover of this auxiliary box that is the object of the invention.

Figure 2 shows an exploded isometric view with the main components of the exterior of the battery and the part of the auxiliary box object of the invention according to a preferred embodiment of the invention.

Figure 3 shows an exploded isometric view with the main components of the battery disassembled, both the cover of the main box and the cover of the auxiliary box object of the invention, as well as the fixing of both covers to their respective boxes.

PREFERRED EMBODIMENT OF THE INVENTION

An example of a preferred embodiment is described below with reference to the figures cited above, without this implying any limitation on the scope of protection of the present invention.

In figure 1 you can see a view of the exterior of a battery (4) that consists of the main box (2), where a cover (3) can be seen. The auxiliary box (1), which consists of an auxiliary cover (5), is attached to one side of the main box. Both boxes (2) and (1) are connected by an internal cavity (6), which can be seen in Figure 2, which enables the passage of components between said boxes.

The main box (2) is where all the cells, cooling system and other components of the battery (4) are housed. Said main box has a cover (3) that protects the components from the outside. This cover (3) is attached to the main box (2) by means of fixing screws (7) that are directly threaded into holes (8) made in the main box (2). This union can also be by welding or be directly an extension of the main box (2).

The auxiliary box (1) is the component object of the invention that incorporates all the electronics and control components that allow easy repair and maintenance of the battery. Said auxiliary box (1) is welded to the main box (4). In the coincident part between both boxes (2) and (1) there is an internal cavity (6) as a connection between said boxes. For its part, the auxiliary box (1) has an auxiliary cover (5) that is attached to it by means of fixing screws (9) through threaded holes (10).

However, it has been envisaged that said auxiliary box (1) and auxiliary cover (5) may have other different geometries and / or dimensions.

Claims (3)

Auxiliary box (1) characterized in that it preferably has an essentially cuboid shape, and because it is attached to one of the outer side walls of the main box (2), where all the cells, the cooling system and other components are housed. battery (4), because it has an auxiliary cover (5) that is attached to it by fixing screws (9) through threaded holes (10) and because it has a cutout or hole (6) that connects both boxes inside and that, consequently, allows the passage of wiring and other components inside. 2. Auxiliary box (1), according to claim 1, characterized in that said main box (2) has a cover (3) that protects the components from the outside and is attached to the main box (2) by means of fixing screws (7) that they are directly threaded into holes (8) made in the main box (2), where this joint can also be by welding or be directly an extension of the main box (2). 3. Auxiliary box (1), according to claim 1, characterized in that the outer face of the main box (2) to which said auxiliary box (1) is attached will preferably be whichever design is better accessible at the location. end of the entire battery assembly for maintenance or repairs. between the main box (2) and the auxiliary box (1).
