Description

A battery arrangement for a vehicle, a battery arrangement set and a vehicle
TECHNICAL FIELD
The present disclosure relates to the area of batteries adapted for electric vehicles. Particularly, the present disclosure relates to a battery arrangement for a vehicle. The present disclosure further relates to a battery arrangement set comprising a battery arrangement and to a vehicle comprising a battery arrangement.
BACKGROUND
Electric vehicles are expected to increase in demand in the coming years and thereby to change the modern transportation system. Progress within technologies related to batteries has recently had an important impact on the development of electric trucks, busses and other heavy duty vehicles.
A heavy duty vehicle requires for its operation batteries that may have a significant weight. Because of demanding operation environments mounting of such heavy batteries is challenging and important to ensure reliable operation of the vehicle.
Efforts have been made to develop mounting arrangements for batteries for heavy duty vehicles. Depending on the type of construction of a heavy duty vehicle, there is usually free installation space under the vehicle's frame between the wheel axles.
This space is often used for mounting of batteries.
A mounting arrangement for batteries can comprise brackets adapted to be attached to the frame of the vehicle and adapted to carry the batteries. One drawback with using brackets is that, brackets with reinforcements required for handle heavy batteries could sometimes weigh as much as the batteries themselves. Weight of the mounting arrangement is an important parameter which needs to be taken into consideration because of its contribution to the total weight of the vehicle.
In EP3617039A1, a device for supporting a battery is described. The device comprises at least one battery carrier which is attached to an outer side of a vehicle frame. SUMMARY
It is an object of the present disclosure to overcome, or at least alleviate, at least some of the above-mentioned drawbacks and problems.
According to a first aspect of the disclosure, the object is achieved by a battery arrangement according to claim 1. Thus, the object is achieved by a battery arrangement for a vehicle, comprising: a battery, a housing comprising a chamber part arranged to accommodate the battery and a lid part arranged to be connected to the chamber part to enclose the battery within the housing. The battery arrangement further comprises a suspension attachment arranged to attach the housing to a frame of the vehicle.
The battery is an electric unit comprising one or several electrochemical cells with external connections. The battery is arranged for powering of the vehicle, as well as for powering of electrical devices of the vehicle, such as for example, fans, pumps, lamps etc.
Since the chamber part is arranged to accommodate the battery, the battery can be positioned within the chamber part to be, at least partly, enclosed within the chamber part and to be supported by the chamber part. Further, since the lid part is arranged to enclose the battery within the housing when the lid part has been connected to the chamber part, the battery can be completely enclosed within the housing by means of the chamber part and the lid part. Thereby, the battery can be supported by the housing and can be protected from the environment outside of the housing by means of the housing comprising the chamber part and the lid part arranged to be connected to the chamber part. As a result, the weight of the battery arrangement can be reduced because there is no need of an additional protection for the battery as it is required according to the known solutions.
As a further effect, because the housing comprises the chamber part and the lid part, a housing is achieved with few parts, which simplifies the construction of the housing. Thus, a robust housing is achieved providing support and good protection for the battery with few parts that can be manufactured in a simple manner. A housing with few parts enable further reduction of the weight of the housing and consequently reduction of the weight of the battery arrangement, which is advantageous considering the total weight of the vehicle.
The suspension attachment is arranged to attach the housing to the frame of the vehicle and thereby to enable mounting of the housing on the frame of the vehicle. Thus, a robust suspension for the battery is achieved where the housing comprises few parts and provides both support and protection for the battery.

The recess 7.1 may have a depth d’ being, for example, 1/10 of the depth d of the chamber part 6. Thus, the base portion 8 of the chamber part 6 can be inserted into the recess 7.1 of the lid part 7 of a previous battery arrangement 2 in order to interconnect the battery arrangements 2 to each other. The recess 7.1 may have contact with the base portion 8 or there may be a space between the base portion 8 and the recess 7.1 of the lid part 7 when a chamber part 6 has been positioned at a lid part 7 of a previous housing 5 of a previous battery arrangement 2 of the battery arrangement set 1.
The chamber part 6 may be a one piece chamber part made of a metal sheet by a pressing process such as stamping. One advantage with the chamber part 6 manufactured as one piece is that the chamber part 6 is manufactured as one whole part without any additional parts that would complicate the construction of the chamber part 6 and increase the weight of the chamber part. Thus, a robust chamber part 6 is achieved with improved strength. Further, a chamber part 6 is achieved having conditions for reduction of the weight of the chamber part 6 by using the metal sheet for manufacturing of the chamber part 6. The metal sheet is a thin metal sheet. For example, the metal sheet is steel sheet. As an alternative, a plastic material may be used and the chamber part 6 may be manufactured by molding. The lid part 7 may also be a one piece lid part made of a metal sheet by a pressing process such as stamping. One advantage with the lid part 7 manufactured as one piece is that the lid part 7 is manufactured as one whole part without any additional parts that would complicate the construction of the lid part and increase the weight of the lid part. Thus, a robust lid part 7 is achieved with improved strength. Further, a lid part 7 is achieved having conditions for reduction of the weight of the lid part by using the metal sheet for manufacturing of the lid part. The metal sheet is a thin metal sheet. The metal sheet may be steel sheet. As an alternative, a plastic material may be used and the lid part 7 may be manufactured by molding. The chamber part 6 and the lid part 7 may be made of the same material or may be made of different materials. For example, the chamber part 6 may be made of a metal sheet and the lid part 7 may be made of a plastic material.
