An electric road, eroad, e-roadway, or electric road system (ERS) is a road which supplies electric power to vehicles travelling on it. Common implementations are overhead power lines above the road, ground-level power supply through conductive rails, and dynamic wireless power transfer (DWPT) through resonant inductive coils or inductive ...
Ground-level power supplies allow dynamic charging for all vehicles, which greatly reduces the required battery capacity and size since the battery is charged while it is being used. The reduced battery size and capacity reduces cost by about five billion euros annualized for the entire Swedish automotive fleet. The rail and inductive systems ...
Electric vehicle wireless power transfer or wireless charging is generally divided into three categories: stationary charging when the vehicle is parked for an extended period of time; dynamic charging when the vehicle is driven on roads or highways; and quasi-dynamic or semi-dynamic charging, when the vehicle moves at low speeds between stops ...
Sweden has tested electric road systems that charge the batteries of private electric vehicles, and among the tested systems are two ground-level power supply systems that began testing in 2017. [5] The in-road rail system is planned to deliver up to 800 kW per vehicle traveling over a powered segment of the rail, and the system is estimated to ...
The On-Line Electric Vehicle system is split into two main parts: buried segments of inductive power transmitters in the road, and inductive receiver modules on the underside of the vehicle. The use of charging while driving eliminates the need for charging stations, but its installation is costly, and current implementations are limited to 60 ...
Electric road technologies which power and charge electric vehicles while driving were assessed in Sweden from 2013. [ 8 ] : 12 The assessment was scheduled to conclude in 2022. [ 9 ] The first standard for electrical equipment on board a vehicle powered by a rail electric road system (ERS), CENELEC Technical Standard 50717, has been approved ...
Smart charging refers to a charging system where electric vehicles, charging stations and charging operators share data connections. Through smart charging, the charging stations may monitor, manage, and restrict the use of charging devices to optimize energy consumption.
Connected Kerb is a UK-based provider of electric vehicle charging infrastructure, founded in 2017, which aims to make EV charging affordable, sustainable and accessible for all regardless of social status, location or physical ability. In November 2021, the company announced plans to install 190,000 on-street residential charging points across ...
