The patent application enters China through PCT way, the international application number is PCT/EP2021/053252, the international publication number is WO2021/175549, and the patent application is called for the priority of British patent application GB2003348.6 with the application date of 2020 and British patent application GB2101785.0 with the application date of 2021 and 02 and 09. Technical Field The present invention relates to an electric vehicle having an energy storage pack that can be used to provide energy to drive and steer an electric traction motor of the electric vehicle. More particularly, the present invention relates to a motor vehicle that optimizes passenger space and does not lose vehicle dynamics and vehicle distance by increasing the volume of the energy storage package. The invention also relates to an energy storage pack and its arrangement. Background Battery-powered electric vehicles typically have a high voltage battery pack (battery pack). The high voltage battery pack contains thousands of low voltage cells arranged to meet the needs of a single vehicle model. The battery pack contains electrical cells that are electrically configured and mechanically assembled to provide a high voltage for providing energy that allows the electrically driven vehicle to travel a suitable distance between recharging. For example, a daily drive wind (NISSAN LEAF) manufactured by about 2010 will have an initial range (real-world range) of about 70 miles, while a Tesla Model S manufactured by about 20212 will have an initial range of about 200 miles-in each case the energy storage of the battery pack will have a dominant impact on that range. The volumetric energy density of gasoline was 35 MJ/liter and that of diesel was 38.6 MJ/liter, in contrast to 0.9 MJ/liter (tesla Model 3) for the state of the art lithium ion battery packs. Once the energy conversion efficiency and the overall propulsion system volume are taken into account, the volumetric energy density of the internal combustion engine is about 3.0 MJ/liter, compared to 0.6 MJ/liter for a battery electric vehicle (these figures are based on comparing two medium vehicle types: audi A4 and tesla Model 3). The volume required for the energy storage device within the internal combustion engine is about 65 liters plus 170 liters (engine, transmission, intake and exhaust) for the rest of the propulsion system. The volume of an equivalent battery energy storage device for an electric vehicle would be approximately 1170 liters plus an additional 120 liters for the rest of the propulsion system. Since volume is a major constraint of passenger cars, the volume available for battery packs on medium-sized vehicles is limited to about 400 liters. The disadvantage of this is that the distance between refuelling (recharging) is 600KM for the best battery trolley (tesla Model 3 long endurance in WLTP cycle), compared to 1380KM for diesel locomotives of the same size (odia 4TDi in WLTP cycle). The battery pack volume will continue to be an important constraint on battery pack energy level and range. The battery pack is typically between 150L for small vehicles (type a vehicles) and up to 460L for large luxury vehicles, which is significant compared to the tank volumes for conventional small vehicles 35L and large luxury vehicles 100L. Once the energy conversion efficiency and the difference in propulsion system component volumes are taken into account, the energy of the battery pack is approximately 480 liters and 1340 liters compared to those of the fuel tank, which requires a relatively large amount of packaging space in the same vehicle. Table 1 shows the conventional vehicle interior volumes according to the U.S. EPA classification and conventional volumes of propulsion systems. TABLE 1 In-car packaging space is a critical constraint for passenger cars. Fig. 1a shows a schematic plan view of a layout of a conventional passenger car 2 with a car body 4 and two axles 6 and wheels 8 at each end of the axles 6. The "front bay" of the vehicle 2 extends from the area of the front tire 8 to the front of the vehicle (to the left, as shown), while the "rear bay" 12 extends from the area of the rear tire 8 to the rear patch of the vehicle (to the right, as shown). Between the front bay 10 and the rear bay 12, between the axles 6 of the vehicle, is a "cabin area" 12. Along the edges of the vehicle are impact layers, such as cushioning regions 16. Critical components, such as batteries, tend to be remote from the strike layer to reduce the likelihood of compliance during a crash. The area storing the batteries or its accessories is generally described as being disposed in one or more of the 7 areas, as shown in fig.
