Physiological compatibility of wireless chargers for electric bicycles
2015
The Inductive Power Transfer represents a viable solution of wireless battery charging for all users of electric mobility. This method brings some benefits to the electric vehicles, being a convenient technique, compared to the conventional wire-based battery charging. Among the electric vehicles, the electric bicycles particularly fit with this innovative method of battery charging. Nevertheless, the physiological effects of the produced magnetic fields need to be taken into account. In this paper, the design of an Inductive Power Transfer system for E-bike wireless battery charging is presented and the measurements concerning the surrounding magnetic field are provided in order to validat…
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…
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…
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…
Getting Physically Active by E-Bike : An Active Commuting Intervention Study
2020
Introduction: Increased physical activity (PA) is a major component in promoting public health, and active commuting could make an important contribution. Using an electric bicycle (e-bike) is reported to be of at least moderate intensity PA and is an alternative to other modes of transport for commuting. We aimed to explore the experience of commuting by e-bike in an intervention study. Methods: Focus group interviews with 21 previously inactive participants from three cities in Norway, who were given access to an e-bike for commuting for three (N = 2) or eight months (N = 19). Participants cycled for 226 days on average. The interviews were analyzed using systematic text condensation. Res…
Magnetic field effects on human body of wireless chargers for E-bikes
2017
For the electric vehicles battery charging, the wireless power transmission is increasingly representing an innovative solution. The inductive power transfer is the standard technology of wireless charging: the energy transfer occurs between two magnetically coupled coils. Although this battery charging system is especially convenient for E-bikes, the physiological effects of the related magnetic fields shall be estimated and taken into account. In this paper, a 200 W prototype of wireless battery charger for E-bikes is proposed and described. Moreover, various measurements of the surrounding magnetic field are carried out to evaluate the actual physiological compatibility of the system.
