A interleaved parallel LLC converter is proposed as a DC/DC for digital off-board charger in accordance with the high output power requirements of modern electric vehicle chargers. The utilizes hybrid control strategy pulse frequency modulation (PFM) and width (PWM) that can greatly increase adjustable voltage range. As result these designs, silky target be achieved. has been rigorously analyze...

This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced w...

This paper presents a low cost reduced instruction set computer (RISC) implementation of an intelligent ultra fast charger for a nickel–cadmium (Ni–Cd) battery. The charger employs a genetic algorithm (GA) trained generalized regression neural network (GRNN) as a key to ultra fast charging while avoiding battery damage. The tradeoff between mean square error (MSE) and the computational burden o...

The future charging of the growing fleet of Electric Vehicles (EV) requires new solutions that guarantee a better efficiency and widely spread chargers. Both in fast charging and in slow charging of the electric vehicle (EV) and hybrid electric vehicle (HEV), the wireless charger is the better choice. The wired charger is limited by its cabling and relatively lower output voltage, while the con...

In this paper, the design of a contactless charger for the lithium-ion battery of a cellular phone is presented. In this charger, the primary core of the transformer is in the charger unit and the secondary core is in the telephone. The gap (3 mm) between them is the thickness of the two plastic cases. The transformer core design for the maximum coupling coefficient with the size constraint on ...

The configuration of security mechanisms in automotive onboard networks makes it necessary to define and deploy adapted security policies. This paper discusses how to design policy engines that implement an effective enforcement in such architectures despite the complexity of the protocol stacks of on-board electronic control units. It also evaluates how policies expressed in XACML can be adapt...

We report breech pressure measurements during the firing of an air cannon. We find that the pressure record is a useful and convenient diagnostic of the penetrator projectile motion during launch—supplementing or replacing beamor wire-breaking speedometers and on-board accelerometers. With little effort, launch speed can be measured with a 2σ error of 1.75 m s−1 or better than 5%.
