Sebuah Catatan Dari Alam dan Pengalaman

The concept of V2G technology was introduced by Kempton and Letendre in 1997. In a typical power grid, the power flows between energy producers through the power network to aggregators and homes. In the homes, power outlets provide energy to products such as electric vehicles. By default, the EVs should be able to connect to the grids to recharge their batteries. An electric vehicle that incorporates V2G technology can also provide energy back to the power outlet when the vehicle is parked. The EVs require additional setup to successfully return the power to the grid to perform this type of bidirectional charging.

Implementing a V2G architecture could potentially decrease the stability of the power grid. However, aggregators employ dispatch and control algorithms to optimize that stability and balance the energy distribution to the EVs. In that way, a vehicle can ultimately charge during the times when energy demand is low and discharge when it is high. However, the potential effect that this may have on the stability of the power grid has not been studied sufficiently. Furthermore, the data that is collected can be susceptible to security issues, and privacy concerns among consumers might arise . Ideally, these challenges will be addressed before the technology becomes adopted on a large scale.

The benefits of V2G technology are technical, economic, and environmental in nature. First, the grid’s power storage capacity will increase gradually with the increase in the number of EVs sharing the power with the grid, allowing more power storage in the grid. Second, the transition to V2G technology can replace 6.5 million barrels of oil usage per day, and it directly amounts to economic savings in a country . Third, the transition can reduce greenhouse gases emitted by gasoline-based vehicles and promote EVs’ usage in society.

The V2G systems need communication protocols to enable the transmission of instructions between the EVs and the electric vehicle supply equipment (EVSE). When the communication chips and protocols are in place to receive the signals, the aggregator can coordinate between the EVs and the electricity grid operator to regulate power supply and demand. The communication protocols related to EVs are divided into front-end and backend protocols.

The front-end protocols define the link between the EVs and EVSEs, and also specify the requirements related to charging topologies (such as type of charging equipment (on-board/off-board) and type of charging (conductive/inductive), safety, charging plugs, communication, and cybersecurity. A few examples of front-end protocols include IEC 61851, ISO 15118, SAE J2847, and CHAdeMO.

The back-end protocols define links between the EVs and third-party operators such as charge point operators (CPOs) (companies responsible for operating a pool of charging points ), and specify requirements related to communication and cybersecurity . A few examples of back-end protocols include the open charge point protocol (OCPP), IEC 63110, the open automated demand response (ADR), and EEBUS. More information on these standards can be found in .To technically realize the V2G system, a simple communication chip is added to the onboard charger of the EVs to regulate the power flow between the EVs and the grid.

However, designing this communication technology is expensive. Therefore, most EVs are not equipped with these chips today, except for a few EVs manufactured by companies such as Nissan and Mitsubishi. Besides, energy meters capable of measuring the power flow between the grid and EVs accurately are required. For monitoring the real-time power flow, advanced metering infrastructure (AMI) is used to provide reliable information to aggregators and grid operators for managing the power flow in and out of the grid . Currently, one technology, CHAdeMO, already offers V2G technology, while another technology, CCS Combo, is expected to offer V2G technology in the future.

Electric Vehicle Fast DC Charging: Holistic Overview

AC Charging and DC Charging Concept Diagram

AC charging is generally referred to as ‘slow charging’ due to its power limitation (22 kW at the highest end typically and the minimum necessary time to charge. The AC higher power ranges (11 – 22 kW) might occasionally be referred as ‘high power AC charging’ or ‘fast AC charging’, there is no actual definition though. On the other hand, those DC chargers with ratings as of 22 kW and spanning up to even 400 kW are considered ‘fast’. The term ‘ultrafast’ is as well used for powers above 50 kW, but there is no actual clear line or definition. The most common DC power ranges deployed nowadays range from 22 – 150 kW, with power ranges between 200 – 350 kW gaining traction. Fast and ultra−fast DC chargers are generally only available publicly at dedicated areas with access to a three−phase power connection to the grid. Charging stations, predominant so far along highways, might display multiple ultra−fast chargers ( > 150 kW each). Such facilities requires a dedicated high voltage transformer from the grid.

Charging Rates and Times

Charging time = Battery capacity (effective) *1 [kWh] / Average Charging Power [kW]

Range of a full battery = Battery capacity (effective) *1 [kWh] / Efficiency [kWh/ 100 km]

60 kWh / 100 kW = 36 min

60 kWh / (18 kWh/100 km*2) = ~ 333 km

*1 For the purpose of this exercise the complete battery capacity is considered. There might be

EVs that might pose a limitation on the full ‘effective’ capacity.

*2 Generic value, will depend on the characteristics of each vehicle. Normally will fall between

12−23 kWh/100 km

What are some of the Important Standards for DC Charging?

IEC 61851. The International Electrotechnical Commission (IEC) has developed several of

the standards listed in the previous section. The IEC 61851 refers to ‘Electric Vehicle Conductive Charging Systems’ and is the central piece of the IEC series for EV charging, focusing on different topics of electric vehicle conductive charging system, including AC and DC charging up to 1000 V and 1500 V respectively [13]. This standard defines four different charging ‘modes’, where the first three ‘modes’ (1 to 3) refer to AC charging and ‘mode’ 4 addresses DC charging. The IEC 62196 defines ‘Plugs, socket−outlets, vehicle connectors and vehicle inlets’ and the IEC 61980 addresses ‘EV wireless power transfer (WPT) systems’. The ISO17409:2020 is the foundational standard on EV charging from the International Organization for Standardization (ISO) and complements exclusively the IEC 61851 discussed above. The documentation addresses ‘Electrically propelled road vehicles — Conductive powertransfer — Safety requirements’ for charging ‘modes’ 2,3,4 defined in IEC 61851−1.

THE MOST COMMON EV ABBREVIATIONS AND WHAT THEY MEAN

Most industries, from science to healthcare to marketing, are chock full of acronyms, to the point where reading or listening to anything related to the industry can be mystifying to anyone on the “outside”.

The electric vehicle industry is no exception. In fact, abbreviations are so common in this industry that we were able to create an entire article out of them.

Whether you’re new to the world of electric vehicles and electric vehicle charging (or you’ve been around for a while and are, at this point, too afraid to ask), we hope that this list helps you understand more about the world of electric vehicles.

THE MOST COMMON EV ABBREVIATIONS AND WHAT THEY MEAN

In a hurry? Click on the abbreviations to jump to the definition.

AC (Alternative current)

This type of charging is useful for charging electric vehicles at different speeds through an alternating current. Electric vehicle charging always comes out as AC. With an AC charger, the power is converted to DC by the vehicle itself. This type of charging is economical but takes longer.

Typical AC charging powers are 3.7kW, 11kW, 22kW (the higher, the faster). However, note that AC charging speed is not only dependent on the charging device capabilities; charging speed is also defined by the vehicle's AC charger.

BEV (Battery electric vehicle)

BEVs are a type of electric car that exclusively get their energy from rechargeable battery packs. BEVs do not have an internal combustion engine, a fuel tank, or a fuel cell.

CCS (Combined charging system)

It offers both AC and DC charging on the same port and provides power of up to 350kW. This is the industry-standard method for public charging stations and also home charging set-ups in Europe and America. It may also be called a “combo plug”.

CHAdeMO (CHArge de MOve)

Contraction of CHArge de MOve, CHAdeMo is a fast (DC) charging technology. The expression finds its roots in the following Japanese sentence: “O cha demo ikaga desuka”, which translates into “would you like a cup of tea?”. The reference to tea is here to remind us that it takes very little time to charge the battery of a CHAdeMO vehicle.

CPM (Charging point manager)

This refers to a type of software responsible for smart charging, i.e., allocating power to different electric vehicles to make sure that each one charges as quickly as possible. It relies on customisable algorithms to work efficiently.

CPO (Charging point owner)

A CPO is an operator who owns and oversees the operation of electric vehicle smart charging points.

DC (Direct current)

DC is one of the two types of ‘fuel’ that can be used to power electric vehicles. Unlike AC charging, converted into DC power by the car, DC charging can convert the AC power into DC right in the plug itself. DC chargers are larger, more expensive, but faster. It will be more common at public charging stations, such as at a rest stop charge point.

DLM (Dynamic Load Management)

Dynamic Load Management (or DLM) refers to an EV charging technology that makes it possible to evenly distribute the electricity to all the vehicles that might be plugged simultaneously. In other words, DLM optimises charging speed and prevents all grid congestion episodes.

DSO (Distribution system operator)

These are the operating managers and/or owners of energy distribution networks.

EMP (Electro-mobility provider)

An EMP is a company that provides customers access to an electric vehicle charging network. They will often offer a tracking service such as an app for evaluating the availability of charging stations. EMPs are also responsible for determining the price of electric vehicle charging.

EMSP (Electro-mobility service provider)

EMSP is simply another way to say EMP (electro-mobility provider).

EV (Electric vehicle)

EV stands for electric vehicles (or electric cars). EVs are equipped with a battery-powered motor instead of a traditional internal combustion engine. Contrary to PHEVs and HEVs, EVs do not have a gasoline tank and output zero tailpipe emissions. They are associated with a lower carbon footprint than traditional vehicle types.

EVSE (Electric vehicle supply equipment)

EVSE refers to equipment that exists to supply electrical energy for charging electric vehicles. It can be residential (such as an at-home charger) or commercial (such as chargers at malls, workplaces, rest stops, etc.).

GHG (Greenhouse gas)

Greenhouse gases are gases in the atmosphere that trap the sun’s heat and warm the Earth, contributing to climate change. The Earth’s most common greenhouse gases are ozone, nitrous oxide, water vapour, methane, and carbon dioxide. Cars with internal combustion engines emit greenhouse gases through their tailpipe.

HEV (Hybrid electric vehicle)

HEVs use both electric batteries and gasoline. More often than not, the electric motor is here to assist the internal combustion engine, during the acceleration phases, for instance. Note that HEVs cannot be plugged into regular EV charging stations. Batteries replenish themselves via the energy generated by the combustion engine or via regenerative braking.

ICE (Internal combustion engine)

Internal combustion engines use liquid fuel (gasoline) to create energy to power traditional vehicles. ICE cars are the most common vehicle on the road (although an increase in EV infrastructure means electric cars are becoming more accessible).

kW (kilowatt)

kW is a measurement unit used to determine how much power an electrical appliance consumes.

kWh (Kilowatt-hour)

kWh defines the amount of energy that is required to power an electrical appliance for one hour.

PHEV (Plug-in hybrid electric vehicle)

PHEVs rely on both electric batteries as well as gasoline to power an ICE. These vehicles run on electrical power until the battery is depleted and automatically switch to the ICE. Charging hybrids can also be plugged in to charge their engine.

RFID (Radio-frequency identification)

RFID is a type of technology that links a card to an account. It can be used in electric vehicle charging to quickly and conveniently start a charge through tapping.

TSO (Transmission system operator)

TSO is a term defined by the European Commission that describes an organisation in charge of transporting energy and maintaining the infrastructure for transporting energy.

V2B (Vehicle-to-building)

Vehicle-to-building is a technology that lessens a building’s energy consumption by drawing on the untapped energy of multiple idle electric vehicles.

V2G (Vehicle-to-grid)

V2G is a new smart charging technology that can push the energy stored in electric cars’ batteries back to the power grid. As we’re increasingly relying on renewable energies to power the grid, V2G is the technology that will stabilise the grid when the energy produced via renewable solar or wind sources can’t meet the demand.

V2H (Vehicle-to-home)

A technology that allows the battery of an electric vehicle to power an entire home (or other building of similar size). This is a bi-directional system with the power to convert energy between AC supply and electric car battery.

V2X (Vehicle-to-everything)

A technology that allows the battery of an electric car to provide general backup power in the case of an outage.

Installing DAMASK Using Binary Source Code Method to Intergrade with MSC Marc

The development of DAMASK started in 2006 with the establishment of a new research group named Computational Mechanics of Polycrystals (CMCn) at the Max-Planck-Institut für Eisenforschung (MPIE). The aim of this joint research group between the Max-Planck-Gesellschaft and the Fraunhofer-Gesellschaft was the development of enhanced material models and simulation technologies from the single crystal up to the component scale [48]. In the course of the CMCn project, it turned out that the Crystal Plasticity (CP) codes existing in the public domain at that time were not flexible enough for this purpose. Therefore, a new CP implementation was initiated, aiming at a strict modularization to allow for flexible incorporation of material models on all length scales. Within the CMCn project, two different homogenization schemes and various constitutive models for plasticity have been incorporated into the new code. The capability to choose from a set of different available constitutive models within a single simulation is a unique feature of the developed simulation framework. Together with R.A. Lebensohn from the Los Alamos National Lab (LANL), Humboldt awardee at MPIE in 2010, a spectral method based mechanical boundary value problem solver was added to complement the existing user material interfaces to commercial Finite Element Method (FEM) solvers. In addition to the core routines, numerous utilities for pre- and post-processing have been added to the package now referred to as DAMASK.

In September 2011, a website (https://damask.mpie.de) was launched to release the code to the public domain as free software according to GPL 3. The idea of a flexible open source CP implementation was very well received by the scientific community. Presently, more1 than 50 groups across the world use DAMASK, including universities such as University of California Los Angeles (UCLA), research facilities such as LANL, and multinational companies such as Tata Steel. These groups contribute to the further code development as well, e.g. by adding features such as new or modified constitutive models.

In 2015, multi-physics extensions were incorporated into DAMASK to consistently treat coupled problems, such as thermo-mechanics, chemo-mechanics, and damage-mechanics. Since early 2016, the code is hosted in a public repository using GitLab (see Appendix A for details) to enable and assist collaborative development among the growing user community.

Source Code

The DAMASK core is written in Fortran 2018 with a few enhancements in C. The pre- and post-processing tools are written in Python 3. A Unix-style operation system is a prerequisite for installation from source. DAMASK has been installed on different GNU/Linux distributions and on MacOS. Compilation on Windows is possible via the Windows Subsystem for Linux (WSL).

1. Download, check, and unpack the source code:

wget https://damask.mpie.de/download/damask-3.0.0-alpha5.tar.xz
wget https://damask.mpie.de/download/damask-3.0.0-alpha5.tar.xz.sha256

---> sha256sum -c damask-3.0.0-alpha5.tar.xz.sha256
----> tar -xf damask-3.0.0-alpha5.tar.xz

2. Get an overview of the prerequisites available on your system:

cd damask-3.0.0-alpha5

./DAMASK_prerequisites.sh

cat system_report.txt

Grid and Mesh Solver

A recent version of the GNU Compiler Collection, the Intel Parallel Studio XE, or the Intel oneAPI toolkit is needed to build the grid solver and/or mesh solver from source.

Warning

The ifx Fortran driver from the Intel oneAPI toolkit does not yet support constructs from Fortran 2018 used in DAMASK.

The solvers included with DAMASK are build with CMake and rely on PETSc. A PETSc installation with support for MPI and the following external packages is needed:

(a) BLAS/LAPACK

(b) HDF5 with MPI support, zlib support is strongly recommended

(d) Packages such as SuperLU, HYPRE, MUMPS, or ML for certain sparse linear solvers.

If all prerequisites are installed, compiliation and installation follows the standard CMake procedure:

cmake -S damask-3.0.0-alpha5 -B build-grid -DDAMASK_SOLVER=grid

cmake --build build-grid --target install

cmake -S damask-3.0.0-alpha5 -B build-mesh -DDAMASK_SOLVER=mesh

cmake --build build-mesh --target install
