Micro-controller Based Electrical Energy Monitoring And Control System for a Low Power Two Wheeler Application

Automotive electrical system forms the backbone of the modern vehicles. The increase in electrical and electronics equipment fitted in the vehicle has resulted in increased power requirements. Today's two-wheeler vehicle electrical system has a magneto, which is the main source of energy and it is directly coupled with the engine shaft. The magneto output charges the battery as well as supplies power to the load.Because of the engine magneto coupling, as the engine speed increases, the output power of the magneto also increases. So even when power is not required and not necessary in certain situations, power is being generated but not utilized, at the cost of loading the engine and thereby increasing its fuel consumption. This surplus power generation causes power wastage and leads to inefficient power utilization. This unnecessary loading of the engine also reduces the engine torque for traction.The electrical loads on the battery and the magneto are at present controlled by the usage pattern of the driver because the loads are directly linked with the sources by means of the switches.…
