FIELD OF THE INVENTION

[0001] The present invention generally relates to the field of batteries. In particular, the present invention relates to an efficient way of utility of rechargeable Universal battery system and battery exchange program by having multitude of recharge stations as well as mobile battery exchange stations, which are provided at strategic locations.

BACKGROUND OF THE INVENTION

[0002] Hybrid vehicles are known in the art that operate on more than one fuel source, typically fossil fuels and an electric battery. The typical fuel sources include petrol, diesel, compressed natural gas, batteries, and combination thereof to drive the engine of the vehicle. Typical hybrid or electric vehicles developed in the art use an electric motor or a combination of electric motors and a fossil fuel to provide the drive to the wheels of the vehicle. These hybrid or electric vehicles which employ the use of electric power typically include battery systems, which has one or more batteries to store electricity. When the vehicle is mobile, an alternator in the vehicle operates use the motion of the wheels to charge these batteries. However, for fully battery-operated vehicles, this recharging does not suffice, and the batteries need to be recharged externally via a static or an electric outlet.

[0003] To this end, US6310464 discloses an apparatus for charging the battery of an electric car. The apparatus comprises a battery charge controller, a battery charger, and a battery. The charge controller being capable of detecting the charge status of the battery, and upon detecting an under-charge condition of initializing, at any given time, a charging process wherein the battery is charged an expected charge amount which is dependent on the degree of under-charge initially detected by the charge controller. The charge controller upon termination of the charging process detects the actual charge amount and compares that amount to the expected charge amount and calculates a difference value. If the difference value exceeds a predetermined reference value, the controller charges the battery pack an additional predetermined amount.

[0004] US5539296A discloses a battery charging method and system which are applicable to battery-powered vehicles. According to the charging system of the invention, there is provided a primary charger including a primary winding which is connectable with a source of charging alternating current at a charging station. There are also provided at least two secondary chargers each connected with a battery on each vehicle and including a secondary winding having a number of winding turns, which is different from that of the winding of the other secondary charger. Transfer of electrical energy from the primary charger to the secondary chargers is accomplished by inductively coupling the primary winding with any selected one of the secondary windings, as a result of which a voltage, the magnitude of which is dependent on the turns ratio between the primary and secondary windings, is produced across the selected secondary winding.

[0005] US5049802A discloses automated charging systems for vehicles having rechargeable batteries that are in common use today. Such systems typically have exposed contacts or the need for additional circuitry to move the contacts. The subject system includes circuitry which allows the charge receiving member to be only connected to the battery during charging. The charging system produces a charging signal in response to a low battery. A microprocessor receives the charging signal and responsively produces a "pulse" signal. A second transistor switch receives the "pulse" signal and responsively energizes a charging contactor coil. In response to the charging contactor coil being energized, contacts controllably block power from the battery to the motor and pass power from the receiving member to the battery.

[0006] However, a disadvantage associated with the aforementioned prior art documents is that none of the systems described in the prior art envisage a universal battery charging system that can be used to charge batteries of different ratings. Further, none of the conventional systems disclose the Universal modular and swappable batteries which can be swapped at various strategic locations, when charging the battery is not an option due to time constraints. Here the Vehicle does not have to wait for charging to occur in the batteries. The driver of the Vehicle simply drives to the battery exchange station and swaps the discharged battery for a charged battery and pay for the difference in the charges.
