Design, implementation and experimental results of a wireless charger for E-bikes

2019

Based on the Inductive Power Transfer (IPT), the wireless energy transmission is increasingly representing an attractive solution for vehicle battery charging. Due to its high smartness, the wireless solution may be considered an interesting battery charging method for electric bicycles, as they represent light-weight and flexible means of transportation. According to the Vehicle-To-Grid (V2G) concept, the wireless power flow can occur in both the alternative directions: from the grid to the battery or in the opposite way. A Bi-Directional Inductive Power Transfer (BDIPT) system is therefore particularly convenient in the scenario of a multi-parking area. For the E-bike application, a bicyc…

Efficiency optimization in bi-directional inductive power transfer systems

2015

Inductive Power Transfer (IPT) allows to wirelessly supply electronic devices. Thus, it is a very smart technique of battery charging for electric vehicles. In a parking area scenario, IPT is a proper method aiming at the energy transfer from the vehicle battery to the electric grid too. Bi-Directional Inductive Power Transfer (BDIPT) Systems are an attractive solution for the automotive market. Due to the great relevance of the energy saving problem, the goal of an efficiency maximization is researched by the energy market. In this paper, an in-depth investigation of the power efficiency in BDIPT systems is carried out, aiming at the optimum efficiency.

An inductive charger for automotive applications

2016

The inductive charging represents a valid solution for the power transfer in automotive applications. Due to the Inductive Power Transfer (IPT), the wireless battery charging of Electric Vehicles (EVs) provides several benefits. In this paper, an inductive charger which is particularly suitable for electrical bicycles is proposed. A practical realization of the system has been carried out, and the system has been tested in terms of working and efficiency. Through a Phase Shift Modulation (PSM), a power regulation has been implemented. The target power is 100 W.

Experimental Investigation on Magnetic Field Effects of IPT for Electric Bikes

2018

The wireless power transmission (WPT) is increasingly representing a promising technology and an innovative solution, especially for the electric vehicles (EVs) battery charging. The inductive power transfer (IPT) is the standard technology of wireless charging: the energy transfer occurs between two magnetically coupled coils. The IPT-based battery charging is especially convenient for E-bikes and the physiological effects related to the generated magnetic fields should be estimated. In this context, this work presents a 200Â W prototype of wireless battery charger for E-bikes. In addition, the measurements regarding the surrounding magnetic field are given in detail in order to evaluate t…

A Bidirectional IPT system for Electrical Bicycle Contactless Energy Transfer

2019

Contactless Energy Transfer characterized by Inductive Power Transfer (IPT) is a viable solution for Electric Vehicle (EV) battery charging, giving advantages in terms of safety, comfort and automatism of the recharging operation. IPT is a smart option for the Vehicle- To-Grid (V2G) implementation as well: the EV's battery can provide power to other users, if possible and if required, in order to adequately respond to an active demand scenario. IPT shall therefore allow a Bidirectional power flow, so that it can be properly defined as Bidirectional IPT (BIPT). In this paper, a 300 W BIPT system for E-bikes is proposed and experimental results are shown as well. Considering power level and s…

Power tracking with maximum efficiency for wireless charging of E-bikes

2014

Wireless charging techniques, based on Inductive Power Transfer (IPT), are attractive for Electric Vehicles (EV), due to benefits such as convenience and safety. An accurate valuation of the maximum achievable efficiency in an IPT system is extremely unlikely due to the high sensitivity to parasitic elements variations. Therefore, an “on site” procedure of power efficiency characterization is useful to get a precise description of the efficiency curve and obtain the actual maximum efficiency. In this paper, a power tracking algorithm aiming at efficiency maximization is proposed for a Wireless Charging system. The algorithm aims at finding the maximum power transfer efficiency with respect …
