DESC:FIELD OF INVENTION
[001] The present invention relates to a battery box for an electric vehicle. More particularly the present invention relates to a removable battery box for a three-wheeler electric vehicle with improved serviceability and easy replacement and repair of the battery.

BACKGROUND OF THE INVENTION

[002] Electric vehicles are becoming increasingly popular due to their environmental benefits and lower operational costs. The electric three-wheeler vehicle includes a battery as a power source. However, these batteries tend to wear out over time and need to be replaced.

[003] One of the challenges with these vehicles is the maintenance and servicing of batteries. Batteries are large and heavy components that can be difficult to service. The servicing of batteries can be a time-consuming process due to complexity and safety considerations.

[004] Conventionally, in most of the three-wheeler electric vehicles, the battery is mounted on the rear side of the vehicle and it is typically housed in a sealed compartment. This makes it difficult to access the battery for inspection, maintenance or replacement. As a result, vehicle owner may need to take their vehicles to a specialized repair shop for even basic battery-related issues. This may cause difficulty in the battery service. Moreover, there are many patent documents disclosing removable battery pack for electric vehicles. One such patent document EP2280436A2 discloses a removable electric vehicle battery pack and electric vehicle equipped with that battery pack. The battery pack is inserted downward into, and disposed in a fixed position in a loading cavity (51) in the electric vehicle (50) to connect the connector (3) to the connecting terminals (52) mounted in the electric vehicle (50) and supply power to the electric vehicle (50). However, the maintenance and servicing of the battery becomes difficult as it is in a fixed position in a loading cavity.
[005] Therefore, keeping in view the problem associated with the state of the art there is a need for an improved battery box arrangement for three-wheeler electric vehicles.

OBJECTIVES OF THE INVENTION

[006] The primary objective of the present invention is to provide a removable battery box for a three-wheeler electric vehicle with improved serviceability
[007] Another object of the present invention is to provide improved air ventilation unit to a mounted battery of a three wheeler vehicle.

[008] Another objective of the present invention is to provide easy access of a battery.

[009] Yet another objective of the present invention is to provide an anti-theft unit to a vehicle for safe and secure battery box.

[010] Another objective of the present invention is to enhance the visual appearance of three wheeler vehicle.

[011] Yet another objective of the present invention is to secure the battery from external damages.

[012] Other objectives and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein, by way of illustration and example, the aspects of the present invention are disclosed.
SUMMARY OF THE INVENTION
[013] The present invention relates to a removable battery pack box for electric vehicles that facilitates better serviceability to the battery. The battery box of the present invention comprises, a battery pack comprising a plurality of batteries; a removable battery openable cap; a locking means attached to the removable battery box to safeguard the battery; an air ventilation unit; and a plurality of fasteners. The battery box can be easily removed by a technician using an ignition key and the box allows quick and easy access to the battery. The removable box have an anti-theft unit and it is directly locked by ignition key. This arrangement is obtained by modifying a front fascia, middle structure and hood frame along with seating arrangement of a three-wheeler vehicle. In an embodiment, the electric vehicle comprises a modified hood frame (005). The modified hood frame is load taking member of driver back rest and support the battery box mounting and canopy. Whereas the conventional hood frame is only capable of used as canopy.
