  • V2G Injector: Whispering to Cars and Charging Units Through the Power-Line
    V2G Injector: Whispering to cars and charging units through the Power-Line Sébastien Dudek, Jean-Christophe Delaunay and Vincent Fargues [email protected] [email protected] [email protected] Synacktiv Abstract. Since vehicles became connected to a bus called CAN (Con- troller Area Network), many “garage” hackers got interested in investi- gating the different controllers, known as ECUs (Engine Control Units), and accessible via the On-Board Diagnostics (OBD) port. Among those different controllers, some of them are accessible via Wi-Fi, others via GPRS, 3G and 4G mobile networks, that could be attacked during a radio interception attack [19]. Moreover, another little-known vector of attack will appear with the deployment of V2G (Vehicle-to-Grid) systems that communicate via power lines support. Nevertheless, no public tool exists to interface with these systems, but also to analyse and to inject V2G traffic. That is why we have developed a tool called V2G Injector to attack these systems. In this article, we will briefly introduce the V2G concept and its similari- ties with domestic Power-Line Communication systems. Then, we will present the techniques we use in our tool that aim to interface with the system, monitor and inject traffic. We will also present a new specification vulnerability in the communication medium we have been able to exploit to intrude the V2G network. To finish, we will talk about issues we have found during our tests on real equipment, and mitigations we can encounter, or apply, in some contexts as well as possible bypasses. 1 Introduction: rise of V2G Due to its environmental friendliness, Electric Vehicle (EV) is gaining popularity in U.S.A, Japan, China and some countries in Europe.

  • EV Connector Types
    Accessed on July 21, 2019. https://www.zap-map.com/charge-points/connectors-speeds/ EV connector types As mentioned in the overview, there are three main types of EV charging – rapid, fast, and slow. These represent the power outputs, and therefore charging speeds, available to charge an EV. Note that power is measured in kilowatts (kW). Each charger type has an associated set of connectors which are designed for low or high power use, and for either AC or DC charging. The following sections offer a detailed description of the three main charge point types and the different connectors available. Rapid chargers 50kW DC charging on one of two connector types 43kW AC charging on one connector type 120kW DC charging on Tesla Supercharger network All rapid units have tethered cables Rapid chargers are the fastest way to charge an EV, often found in motorway services or in locations close to main roads. Rapid devices supply high power direct or alternating current – DC or AC – to recharge a car to 80% in 20-40 minutes. In most cases, the charging units power down when the battery is around 80% full to protect the battery and extend its life. All rapid devices have the charging cable tethered to the unit. Rapid charging can only be used on vehicles with rapid-charging capability. Given the easily recognisable connector profiles – see images below – the specification for your model is easy to check from the vehicle manual or inspecting the on-board inlet. Non-Tesla rapid DC chargers provide power at 50 kW (125A), use either the CHAdeMO or CCS charging standards, and are indicated by purple icons on Zap-Map.

Williamson *,† Electric Mobility and Transportation Innovation (E-MOTION) Laboratory, Smart Transportation Electrification and Energy Research (STEER) Group, Department of Electrical, Faculty of Engineering and Applied Science, Computer and Software Engineering, University of Ontario Institute of Technology, Oshawa, ON L1G 0C5, Canada; [email protected] * Correspondence: [email protected] (D.R.); [email protected] (S.S.W.) † These authors contributed equally to this work. Received: 27 August 2019; Accepted: 25 September 2019; Published: 29 September 2019 Abstract: With the growing fleet of a new generation electric vehicles (EVs), it is essential to develop an adequate high power charging infrastructure that can mimic conventional gasoline fuel stations. Therefore, much research attention must be focused on the development of off-board DC fast chargers which can quickly replenish the charge in an EV battery. However, use of the service transformer in the existing fast charging architecture adds to the system cost, size and complicates the installation process while directly connected to medium-voltage (MV) line. With continual improvements in power electronics and magnetics, solid state transformer (SST) technology can be adopted to enhance power density and efficiency of the system. This paper aims to review the current state of the art architectures and challenges of fast charging infrastructure using SST technology while directly connected to the MV line. Finally, this paper discusses technical considerations, challenges and introduces future research possibilities. Keywords: electric vehicles; energy storage; fast charging station; power converters; solid state transformer; transportation electrification 1.

  • Lecture Notes: DC Charging Of
    Electric cars: Technology Lecture notes: Lecture 3.3 DC charging DC Fast Chargers supersede Level 1 and Level 2 charging stations and are designed to charge electric vehicles quickly with an electric output ranging between 50 kW – 350 kW. With high power operation, the AC/DC converter, the DC/DC converter and the power control circuits become larger and more expensive. That is why DC fast chargers are implemented as an off-board charger rather than as an onboard charger so that it does not take up space within the vehicle and the fast charger can be shared by many users. This course material is licensed under a Creative Commons Attibution- 1 NonCommercial-ShareAlike 4.0 License. Electric cars: Technology Lecture notes: Lecture 3.3 DC Charger: Operation • In the first step, the alternating current or AC power provided by the AC grid is converted into direct current or DC power using a rectifier inside the DC charging station. • Then, the power control unit appropriately adjusts the voltage and current of the DC/DC converter inside the charging station to control the variable DC power delivered to charge the battery. • There are safety interlock and protection circuits used to de-energize the EV connector and to stop the charging process whenever there is a fault condition or an improper connection between the EV and the charger. • The battery management system or BMS plays the key role of communicating with the charging station to control the voltage and current delivered to the battery and to operate the protection circuits in case of an unsafe situation.
