![]() ![]() In a technically advanced world where demand is increasing very fast especially large number of non-linear loads and electric vehicles has led to energy crisis and pollution of grid power. ![]() ![]() The second pulsing mode produced capacity values 7-8% higher than in the classical CC-CV protocol, and in charging times periods from 5-25% faster, without compromising the batteries' cycle life. PC and PV) to the total electrodes' capacity, and the thermal variations for each. Different voltage pulse widths and frequencies were tested, in order to study the maximum electrodes' capacity, the time required to reach that capacity, the contribution of each individual step (i.e. The second methodology keeps the same current pulse, however, after the limiting voltage was reached, the pulsing regime consisted in alternating between a maximum voltage value and a minimum, non-zero, constant current value. Firstly, a square current pulse is applied to the cell until the cut-off voltage is reached, followed by a pulsed square voltage protocol (PV). In this work, two new pulsed charging protocols were tested. Intercalation and de-intercalation of Li+ are accompanied by concentration gradients that are reflected by the rise in the cells' potentials that is required to maintain the constant current during the CC regime. Current flow during charging implies an equivalent ionic flow through the battery materials. Lithium-ion batteries are commonly charged following the constant current -constant voltage (CC-CV) protocol. Results show a relatively low power disruption after applying the proposed control during transmitter sequencing. The control strategy was numerically validated using MATLAB Simulink and then tested experimentally. Each transmitter coil is driven by a variable frequency inverter (around 85 kHz) to ensure Zero Phase Angle mode. The studied structure is a symmetrical series–series compensation network. The control integrates a soft start feature and a degraded operating mode at a predefined maximum current value. The proposed control strategy eliminates drop and inrush currents during transient phases. This article presents a novel control strategy for multi-transmitter DIPT systems that ensures a continuous and stable power transfer to a moving EV. Multiple transmitters are required to achieve DIPT thus, dealing with transient phases is essential because every time a receiver crosses over from one transmitter to another, it experiences a new transient phase. Dynamic Inductive Power Transfer (DIPT) systems permit charging EVs while driving, provide unlimited autonomy, and eliminate stationary charging time and lower battery dependency. Although EVs have witnessed significant advancement in recent years, they still have two major setbacks: limited autonomy and long recharging time. They are seen as a way to reduce the CO2 footprint of vehicles. Electrical Vehicles (EVs) have gained popularity in recent years in the automotive field. ![]()
