Description

1 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. Thepresent 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 tochange the modern transportation system. Progress within technologies related to batterieshas 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 dutyvehicles. Depending on the type of construction of a heavy duty vehicle, there is usually freeinstallation 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 theframe of the vehicle and adapted to carry the batteries. One drawback with using brackets isthat, brackets with reinforcements required for handle heavy batteries could sometimesweigh as much as the batteries themselves. Weight of the mounting arrangement is animportant parameter which needs to be taken into consideration because of its contribution to the total weight of the vehicle. ln 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.
SUMMARYlt 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 arrangementaccording 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 thebattery and a lid part arranged to be connected to the chamber part to enclose the batterywithin 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 externalconnections. 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 bepositioned within the chamber part to be, at least partly, enclosed within the chamber partand to be supported by the chamber part. Further, since the lid part is arranged to enclosethe battery within the housing when the lid part has been connected to the chamber part, thebattery can be completely enclosed within the housing by means of the chamber part and thelid part. Thereby, the battery can be supported by the housing and can be protected from theenvironment outside of the housing by means of the housing comprising the chamber partand the lid part arranged to be connected to the chamber part. As a result, the weight of thebattery 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, ahousing is achieved with few parts, which simplifies the construction of the housing. Thus, arobust housing is achieved providing support and good protection for the battery with fewparts that can be manufactured in a simple manner. A housing with few parts enable furtherreduction 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 andthereby to enable mounting of the housing on the frame of the vehicle. Thus, a robustsuspension for the battery is achieved where the housing comprises few parts and provides both support and protection for the battery.
Accordingly, a robust battery arrangement is achieved having conditions for reduction of theweight of the battery arrangement. The housing of the battery arrangement providesimproved protection for the battery from the environment outside of the housing. The housingand the suspension attachment have conditions for providing an improved protection frommovements of the frame of the vehicle during operation of the vehicle, which may improvethe durabi|ity of the battery and of the frame.
