Abstract

Power management control using Zelio Logic Smart Relay is applied as a means to make automatic power transition from battery to generator and vice versa. The design of a hybrid system in a laboratory scale is described including the design of software part using Zelio Soft2 (ANONIM 3, 2014). The experiment results show that the values of voltage and power output of the solar cell will increase with the increasing intensity of the sun, while the current will be decreasing. The current sensor used in the system is able to detect the linear changes of current flowing into the load and to respond in a form of voltage to be inputted into Zelio. The automatic operation of genset can be performed properly and the SFC optimum value of the genset of 2.8 kW, 220 V, 50 Hz is 0.67 l/kWh under 72% loading of the generator capacity. Automatic switching of the hybrid system can be realized based on the sensing results of battery voltage and load voltage with the help of Zelio. Load is supplied through the battery inverter when the battery voltage exceeds its voltage, it is supplied directly from the genset and the relay is activated to charge the battery.

Abstract

To improve the efficiency of electric bike, it takes a regenerative braking system to replace the mechanical braking system for regenerative braking can convert the kinetic energy to be dumped into heat through the brake into electrical energy that can be used to charge the battery.To realize this tool, it takes a bicycle, engine direct current brushless, three-phase uncontrolled rectifier, boost converter, a battery, and a controller. Braking torque on the engine influenced by the current output of the machine. The regenerative braking system is controlled by a microcontroller which will vary in value dutycycle boost converter so that the value of the input current boost converter is always directly proportional to the output current value of the machine can be changed.Based on test results obtained average energy of 0.0048360 Wh for the initial speed of 30 km / h and 0.0100300 Wh for the initial speed of 40 km / h with the engine inertia loads only. Keywords : Regenerative braking, direct current brushless machine, rectifier, boost converters, controllers, batteries, bicycles.
