On the other hand, in the level 3 charging system, the charging operations are split between EV charging stations and on-board chargers for EVs. In these EVs, unidirectional and bidirectional isolated or non-isolated converter topologies are generally utilized. Level (1 and 2) charging systems ...

With an active power factor adjustment linked to the grid, a bidirectional AC–DC converter is available. The second stage is a bidirectional DC–DC converter that controls how the batteries are charged or discharged. Current surges back in a sinusoidal pattern when a charger is in discharge ...
Figure 1.Proposed hardware architecture for the electronic control unit of an electric tractor. Power train—composed of the battery or fuel cell, the power converter, the electric motor, and the battery management system (BMS); Hydraulic system—composed of the hydraulic pump, control valves, hyd...
Unidirectional on-board chargers are only meant for conversion of AC into DC while charging the battery of an EV, which is known as grid-to-vehicle (G2V) mode of operation. In most of the cases, a unidirectional charger consists of a diode bridge, a filter, and a DC–DC converter [...
The EV could act as a buffer for intermittent renewable power sources; when the environment is not perfect for garnering enough electrical energy, using the energy from the battery of the EV fleet could meet the extra load demand. Usually, a boosted DC/DC converter is used with a proper ...
Control algorithms are necessary, based on the cost and rating of the converter used in a charger, using different microcontrollers, digital signal processors, and specialized linear integrated circuits. Ideal voltage and current ratios contribute to longer battery. To address prolonged charging issues,...
Commonly, EVs contain three significant parts: a converter for charging, battery storage, and the type of motor used [6,7]. There are two significant domains of charging methods available in EVs. Those are conductive (plug-in) charging and wireless charging. Conductive or plug-in charging ...
The main battery is a high-voltage battery that stores the energy provided by the regenerative braking and serves as a backup option for the electric motor. The electric motor drives the car’s wheels and is powered by the fuel cell and the main battery. The DC-DC converter converts high...
