DESC:A POWER PACK SYSTEM FOR ELECTRIC VEHICLE AND METHOD THEREOF

Field of the Invention
This invention in general relates to the field of electric vehicle. More specifically, the present invention provides a power pack system comprising one or more batteries, wherein the power pack is placed in sideways slotting mechanism.

Background of the Invention
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art.

Globe is moving towards green environment, working towards multiple innovations to reduce the pollution. The demand and supply challenges of the fuels leads to find out alternatives for the vehicle. Electric vehicles are a great alternative of these challenges. The electric vehicle is generally considered to be an effective way of easing the imbalance between the supply and demand of fuel and in reduction environmental pollution.

Electric two wheelers are a good potential replacement for conventional two wheeler as two wheeler produces substantial harmful emissions. However, price and performance including speed, range, charge time, charging convenience etc. play an important role in the electric two wheeler market. Particularly improvements in battery charging technology, arrangement of battery pack and charging infrastructure impacts consumers' interest towards buying electric two wheelers.

The recent appearance of two-wheelers with electric motors, whether simply to assist pedaling or as a principal means of propulsion, of course requires a battery to be carried, which is a particularly heavy element and has a degree of sensitivity to shocks. The integration of a battery in a frame having one of the configurations usual for bikes poses problems.

Further, the placement of the batteries and charging of the battery for the long-term use is a major challenge currently, specifically the jurisdictions where electric vehicles are new concepts and very fewer charging stations are available. Further, the batteries are heavy, therefore another challenge to work upon is finding a suitable arrangement of the batteries to avoid the balancing issues with the two wheeler.
Among the solutions currently retained, it is known to place the battery vertically in main frame. However, this solution is not entirely satisfactory because it employs pulling out the batteries every time for recharging. Also, it displaces the centre of gravity because of the placement, hence there is a risk of structural imbalance of the two wheeler.

Another solution is to house a battery in an enlarged hub of one, or even both, of the wheels. The behaviour of the bike is then not significantly changed, and its structure is almost identical to that of a normal bike, which guarantees a satisfactory strength and behaviour. However, this solution requires a design of the batteries and their connections that makes them substantially more expensive. Moreover, in this case, it is almost impossible to produce a detachable assembly allowing the user to remove and replace it easily. Urban users very often do not have power supply means allowing the bike to be recharged in its parking space. They are therefore forced to remove and re-place the battery to recharge it at home.

There are multiple solutions that have been provided to resolve the challenges existing with respect to battery placement and recharging mechanism for the electric two wheelers, however, it would be still desirable, to provide a battery box positioning and designing in electric two-wheelers to improve the current state of electric two wheeler construction and make an efficient design that limits the aforementioned drawbacks of the conventional configurations and reduces the overall efficiency of the electric motor.
