DETAILED DESCRIPTION
[023] In recent times, electric vehicles are increasing in demand due to climate change and also to counter the effects of pollution on the environment. These electric vehicles are provided with power units such as batteries. The batteries are provided inside the electric vehicles which runs electric motors and thereby the electric vehicles are driven.
[024] However, the existing electric vehicles have the batteries being rigidly mounted inside the electric vehicles. Hence, the batteries have to charged continuously to run the electric vehicle. However, continuous charging and discharging of the batteries reduces the life cycle of the batteries and leads to limited life cycle of the electric vehicle.
[025] Additionally, when the batteries are rigidly mounted inside the electric vehicle, it becomes difficult to access the batteries and service it. Furthermore, the batteries are not swappable and thereby reduces the lifecycle of the batteries.
[026] In order to overcome the problems of a rigidly mounted battery, swappable arrangements of the batteries are introduced in the conventional electric vehicles. However, the conventional swappable structures are fixedly provided on a frame assembly of the vehicle. Further, design changes are required to be made in the frame structure of the vehicle. This increases the cost of the vehicle and increases the complexity in design of the vehicle.
[027] Furthermore, the frequency of battery removal in electric vehicles with such swappable battery arrangements is high. However, the existing complex swappable arrangement of the batteries increases the battery removal time and also creates difficulty during servicing. Hence, a quick and easily swappable battery arrangement is required.
[028] Further, in cargo and passenger multiwheeled vehicles, the swappable battery arrangements are provided below a driver’s seat in an accessible location. This location enables the driver to lift the seat and easily swap the battery. However, such a location below the seat is prone to impacts and collisions from left and right sides. Thus, during any unnecessary impact, the batteries are easily damaged.
[029] Furthermore, in order to provide a swappable arrangement for the batteries below the seat, the height of the floorboard has to be reduced. This in turn reduces the ground clearance of the vehicle. Alternatively, the height of a hood of the vehicle has to be increased which causes problems to the driver while driving the vehicle.
[030] Additionally, if the swappable batteries are provided only under the driver’s seat, then a front load on the front axle reaction will be higher. This is turn increases the steering effort to be given by the driver. This not only increases the effort to be given by the driver but also creates difficulty in maneuverability of the vehicle.
[031] In some related art, the swappable batteries are provided under the driver seat in between two pillars which provides an encasing for disposal and replacement of the batteries. However, in such an arrangement, the driver cannot access the battery in any direction other than a vertical direction after lifting the seat upwards. However, while lifting the batteries in the vertical direction, the batteries may get hit from the pillars and therefore the batteries may get damaged. Furthermore, this arrangement also reduces the luggage space under the driver seat and also increases the seat height, which causes difficulty for the driver to handle the vehicle properly.
[032] In another related art, the swappable battery arrangements are provided in a rear portion of the vehicles behind the driver seat. However, such an arrangement requires a casing or a protective barrier to protect the batteries from any side collisions or from any entry of dirt and mud. This, is turn reduces the ease of accessibility of the batteries and also increases the part count, cost and weight of the entire vehicle.
[033] Furthermore, if a swappable battery arrangement is provided without the encasing and barriers, then the battery is prone to theft and also the battery gets damaged easily due to atmospheric exposure.
[034] Additionally, the swappable battery arrangement has to be balanced between a front portion and the rear portion of the vehicle in order to maintain the lateral centre of gravity of the vehicle. Furthermore, easier and faster means of accessing the swappable battery is required for providing better access to the driver.
[035] Hence, it is an object of the present invention to overcome all the above stated and other related problems existing in the prior arts, with respect to rigidly fixed battery arrangements and non-uniform load distribution of battery in a swappable battery arrangement for a vehicle as well as other problems of known art.
[036] It is further an object of the present invention to reduce discomfort of the user in accessing the swappable battery.
[037] It is further an object of the present invention to maximize battery safety during any impact or collisions.
[038] It is further an object of the present invention to provide ease of replacement of the battery during servicing of the vehicle.
[039] It is further an object of the present invention to reduce any increase in load deck height or any further reduction in ground clearance.
[040] It is further an object of the present invention to reduce damage to the batteries during frequent removal and replacement.
