    An electric vehicle comprises a chassis (111) which forms a longitudinal tunnel (106) in the longitudinal direction of the electric vehicle. The electric vehicle further includes fasteners (107) for holding an elongated battery module (110) in the longitudinal tunnel so that the tunnel is arranged to act as a space for the battery module. Because the battery module is located in the longitudinal tunnel of the chassis, the center of gravity of the electric vehicle can be kept low. In addition, the center of gravity of the electric vehicle can be located in the middle section (109) of the electric vehicle. Therefore, the weight of the battery module does not cause an unfavorable oversteer tendency as in a case where the battery module is located in the rear part of an electric vehicle.

    FIELD OF THE DISCLOSURE The disclosure generally relates to electric automobiles. In particular, the disclosure relates to an electric vehicle.
    BACKGROUND Electric vehicles have many advantages over conventional vehicles provided with an internal combustion engine. In most cases, the electrical energy used by an electric vehicle can be produced with lower pollutant emissions and less use of non-renewable natural resources, such as in a case where an internal combustion engine is used to convert on-board fuel energy to propulsion energy becomes. In addition, electric vehicles are typically able to recover braking energy, whereas in conventional vehicles provided with internal combustion engines, the braking energy is wasted as heat. An electric vehicle typically includes one or more electric drives for driving one or more wheels of the electric vehicle. An electric drive comprises an electric machine, which is connected directly or via a transmission to one or more wheels and a converter system for converting DC voltage from an operating system into voltages which are suitable for the electric machine. The converter system is advantageously bidirectional to enable the electrical machine to operate not only as a motor to provide the drive, but also as a generator to load the operating system during braking. It is also possible that an electric vehicle is a hybrid vehicle that includes an internal combustion engine in addition to an electric drive system.
    An inconvenience with regard to electric vehicles is the weight and space requirements of a battery system. In a typical arrangement, a battery system is placed in a space under the trunk of an electric vehicle. This arrangement enables the center of gravity of the electric vehicle to be kept low, but an inconvenience of this arrangement is that the center of gravity is located in the rear part of the electric vehicle, causing an unfavorable oversteer tendency because the battery system acts as a pendulum mass in road curves can work. In addition, in some cases a request may e.g. in connection with electric racing vehicles, that a battery module of an electric vehicle must be able to be quickly replaced with another battery module. Furthermore, a safety requirement may be that a battery module should be able to be removed from an electric vehicle while driving.
    OVERVIEW A simplified overview is presented below to provide a basic understanding of some aspects of various embodiments of the invention. The overview is not a comprehensive overview of the invention. It is also not intended to identify key or critical elements of the invention or to delineate the scope of the invention. The following overview presents only some concepts of the invention in a simplified form as an introduction to a more detailed description of the illustrative embodiments of the invention.
    In accordance with the invention, there is provided a new electric vehicle, which may, for example, but not necessarily, be an electric racing vehicle. An electric vehicle according to the invention comprises:

    Figures 1a, 1b and 1c illustrate an electric vehicle according to an illustrative and non-limiting embodiment of the invention, and Figures 2a and 2b represent a battery module suitable for an electric vehicle according to an illustrative and non-limiting embodiment of the invention is.
    DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS The specific examples provided in the description below are not intended to be construed to limit the scope or / and applicability of the appended claims. Lists and groups of examples provided in the description are not exhaustive unless explicitly stated otherwise.
    Figures 1a, 1b and 1c illustrate an electric vehicle according to an illustrative and non-limiting embodiment of the invention. Figure 1a shows a schematic bottom view of the electric vehicle, Figure 1b shows a front view of the electric vehicle and Figure 1c shows a rear view of the electric vehicle vehicle. The viewing directions in relation to FIGS. 1a-1c are represented by a coordinate system 199. The electric vehicle includes a body 101 in which a chassis 111 is arranged to form a longitudinal tunnel 106 on the longitudinal center line of the chassis 111. An advantage of the longitudinal tunnel 106 is that it increases the mechanical stiffness of the body and thereby increases the mechanical stiffness of the electric vehicle. The electric vehicle includes electric drives 102, 103, 104 and 105 for driving the wheels of the electric vehicle. In FIGS. 1a and 1b, one of the wheels is designated with a reference symbol 113. The electric vehicle includes fasteners 107 for holding an elongated battery mode 110 in the longitudinal tunnel 106 so that the longitudinal tunnel is arranged to act as a space for the battery module 110. The electric vehicle includes electrical connectors 108a, 108b, 108c and 108d for electrically connecting the electrical drives 102-105 to the battery module 110. Similarly, the battery module 110 includes electrical connectors that mate with the electrical connectors of the electric vehicle. In this illustrative case, the electric vehicle and the battery module include separate electrical connectors for each of the electrical drives. It is also possible that the electric vehicle, and correspondingly the electric battery module, comprise only one electrical connector, which comprises a sufficient number of electric poles for connecting the electric drives 102-105 to the battery module 110. Advantageously, the battery module 110 further includes a charging port for receiving charging current from an external electrical system. In Figure 1c, the charging port is designated with a reference symbol 123. It is also possible that the electric vehicle includes a charging connector and the charging current is supplied to the battery module via the electric vehicle, but an inherent advantage of the charging connector 123 of the battery module is that the battery module can be charged even if the battery module is from that electric vehicle is disconnected.
    In the illustrative electric vehicle illustrated in Figures 1a-1c, each of the electric drives 102-105 includes an electric machine for driving one of the wheels and a converter system for converting DC voltage from the battery module to voltages required for the electrical machine is suitable. In FIG. 1a, the electrical machine of the electrical drive 102 is designated with a reference symbol 114. In this illustrative case, each electrical machine comprises many separate stator windings that are supplied by separate converters of the respective converter system. In FIG. 1a, one of the converters of the converter system of the electric drive 102 is designated with a reference symbol 115.

    AT 16 612 U1 2020-02-15 Austrian patent office many electrical pole pairs, as there are converters in the corresponding one of the electrical drives 102-105. In this case, each of the transducers can be powered by a battery element that is electrically isolated from the other battery elements that powers the other transducers. The modular arrangement, in which each electrical machine comprises many separate stator windings, which are electrically insulated from each other and are supplied by separate converters and battery elements, makes it possible to achieve high performance, so that the maximum voltage as well as the maximum current can still be relatively small. In addition, the modularity of the type described above improves the fault tolerance of the electric drives 102-105.
    In an electric vehicle according to an illustrative and non-limiting embodiment of the invention, each of the electrical connectors 108a-108d includes at least four pairs of electrical poles for connection to at least four electrically separated battery elements.

In an electric vehicle according to an illustrative and non-limiting embodiment of the invention, each of the electrical connectors 108a-108d includes at least 250 electrical pole pairs for connection to at least 250 electrically separated battery elements.
    The fastening devices 107 for holding the battery module 110 in the longitudinal tunnel 106 can comprise, for example, one or more quick couplers, which can advantageously be controlled / regulated by the vehicle cockpit, in order to enable a driver to release the battery module 110 while driving. For example, the driver may want to remove the battery module 110 from the electric vehicle when a dangerous situation develops. In particular in connection with electric racing vehicles, the quick couplers can also be controllable / regulatable outside the vehicle cockpit, for example to enable maintenance personnel to change the battery module with another during a pit stop. In some cases, however, it is also possible that the fastening devices 107 comprise conventional bolts.
    In an electric vehicle according to an illustrative and non-limiting embodiment of the invention, the longitudinal tunnel 106 comprises a base plate, so that the longitudinal tunnel forms a tubular space for the battery module 110.
