Simulation of Simplified BSPD Deploying Timer Circuit for a Prototype Formula Electric Car

Abstract

Now-a-days electrical vehicles are growing faster than the vehicles fuelled with conventional energy resources and are expected to replace conventional vehicles in near future,owing to its zilch emissions and environmental friendly. Albeit the electrical vehicles are contributing to the reduction in air and noise pollution, few technical issues have to be resolved for its improved performance. Currently electric vehicle is turned off automatically, for avoiding the shaft failure due to the twisting load acting on the shaft, while operator applies the accelerator pedal and brake pedal simultaneously. Hence, an attempt had been made to delay the system getting turned off by introducing a timer circuit in BSPD (Brake System Plausibility Device). The functioning of simplified BSPD with timer circuit was simulated using the Proteus software andthe outcome of the simulated results is presented in waveforms, which confirms the proper functioning of the circuit. A PCB for engaging the shutdown circuitwas also developed to control the electric vehicle’s powertrain. The hardware implementation of the simulated circuit had been carried out and the real time working of the circuit was verified.
