Provident Headlamps Technology for Electric Vehicles

Electric Vehicle (E.V.) relies on its batteries as the power source. One major issue hampering the use of EV is related to its short driving range due to exhaustion of battery. Battery power consumption suffers with many unbounded conditions that result in excess power consumption. Using the battery providently is the basic idea of the work discussed in this paper, and it can definitely contribute in augmenting the driving range of electric vehicle.In this paper, a system is described, by means of which the battery of E.V. can wisely be utilised by the constant loads of headlamps and thus, it becomes Provident Headlamps. By avoiding unnecessary use of battery and using it precisely when and wherever glow is required, battery power can be conserved. A circuitry is designed, which senses the illumination of the surroundings of vehicle and decides the output requirement of headlamps and will regulate the power from battery to the headlamps accordingly, thus conserving battery and slightly increasing the driving range. This technique has been extended to separate controls for left and right lamps, ensuring safety in two way traffic.
