Li Ion batteries are the proficient energy source for powering Hybrid Electric Vehicles (HEV) due to its smaller size, lighter weight, and improved charge efficiency without memory effect. The battery pack constitutes of a combination of cells in series and parallel configurations. Due to cell impedance mismatch, each cell possesses different potentials which cause different State of Charge (SOC)...
During the exploitation of the battle tank, there are different operations that the Gun control system is expected to perform. Most of the contemporary battle tanks employ electrohydraulic drive for the Gun Control system operation. With the advent of compact PMSM motors having good dynamic response, the Gun control system drive choice is moving towards electric drive in view of low maintenance overhead...
Multi radio set configuration in vehicles very often generate undesired mutual EMI (both inter modulation and cross modulation products) frequencies at considerable amplitude. When radio sets are not designed to meet those stringent EMI specifications, retrofits, of RF coaxial filters are the only solution, to reject IM/CM products into victim receiver(s). Three different RF coaxial filters chosen...
In a multi radio set configured land mobile vehicle platform, there are two major issues arising that lead to degradation in system performance There is non linearity in wireless communication system design that gives rise to inter modulation EMI[IMI]and cross modulation EMI [CMI] when systems are operated in close proximity which are mainly responsible for reduction in communication system performance...
Communication System is an EMI sensitive electronics that has a critical role in the combat vehicles. In particular the HF-VHF communication system is very much susceptible to EM radiations from rest of the electronics systems within the vehicle. Similarly if the transmitter is not well designed or not properly installed then, it can be a potential threat to rest of the electronics. Thus it establishes...
