DETAILED DESCRIPTION
[00017] Typically, in a hybrid vehicle with a step-through type frame
• assembly, the frame assembly comprises of a head tube, a main frame. The main
frame extends rearward form the head tube in a downward direction and extends
to the rear portion of the vehicle in an inclined manner. A floorboard is
positioned at the step-through space.
[00018] Generally, a vehicle with a step-through type frame assembly, the IC engine is swingably connected to the frame assembly. The IC engine is operated by gasoline or the like. An on-board battery is charged by a magneto setup of the vehicle when the IC engine is running. In case of an electric vehicle, the electric
motor is provides the forward motion and requires frequent charging. A charger is used to charger a battery, which drives the electric motor. [00019] Generally, a hybrid vehicle incorporates an IC engine and an electric motor. A user can operate the hybrid vehicle in any one of three modes as required namely an engine mode, an electric mode, and a hybrid mode. In the
engine mode only the IC engine is operating. In electric mode, only the traction motor is functioning, so the vehicle functions as electric vehicle. The hybrid

mode further comprises of a hybrid power mode and a hybrid economy mode. In the hybrid power mode bom the IC engine and the traction motor are functioning. In the hybrid economy mode, the IC engine, and the traction motor are operated alternatively. 5 [00020] Generally, the hybrid vehicle functions as an electric vehicle when only the traction motor is operated. The battery drives the traction motor when the vehicle is operated in electric mode or hybrid mode. Use of the traction motor for providing motion reduces the pollution. In case of an electric vehicle or a hybrid vehicle, the battery should be frequently charged when continuously used.
The battery is commonly recharged from a dedicated power grid or a domestic power supply. A dedicated charger regulates voltage for charging the battery. However, the charger should be carried along for charging the battery, for example during long drives. For improving reliability of functioning of the charger, the charger should be secured and protected from external parameters
like rainwater and dust.
[00021] Hence, an objective of the present subject matter is to provide a vehicle. The vehicle comprises a primary charger compartment and a secondary charger compartment. According to an aspect of the present subject matter, the vehicle enables mounting of the charger to underutilized space on the vehicle and
the utility space in the utility box is not compromised. Further, the charger is secured from external parameters like rain, dust etc. According to another aspect of the present subject matter, the vehicle enables on-board and off-board use of the charger. [00022] In an embodiment, the vehicle comprises of a primary charger
compartment formed in a hollow space below a seat assembly, which is on the seat base. The • charger is detachably mounted to the primary charger compartment. In a preferred embodiment, the primary charger compartment is formed in an anterior bottom portion of the seat assembly such that the utility box space is not compromised. A secondary charger compartment is formed in the
rear portion of a leg-shield. The charger is detachably mounted to the secondary charger compartment.
