Type 2 ev charger

Within the next 10 years, the fast charging station will become an essential part of transportation. Consequently, the charging infrastructure should develop in time.

Charging stations are attracting awareness due to the increase in environmental, rise in efficiency, and cost reduction of the PV modules.

This charging station is the ideal solution for those who want to offer a charging service with a simple and immediate payment system.

Charger siting optimization

For the optimization of EV charger locations, you must consider two major objectives, minimizing cost and maximizing utilization. Of course, there are additional important considerations such as other financial support, government grants, planning permission, land/building availability, and equitable access to chargers for different sectors of the area.

Optimum locations for utilization can be determined by answering the following questions:

  • What speed of charger is to be needed?
  • Where are EVs when reaching 80% state of charge on longer journeys?
  • Where will it be convenient for charging?
  • Where will they travel?
  • When and where will EVs be bought?

How will this change over time with evolving technology: autonomous vehicles, shared transport, longer-range vehicles, faster charging, and increased battery capacities?

Optimization of EV charger locations to minimize cost can be based on the following:

  • How are the factors change over the next decade?
  • What are the current available capacity on the Medium Voltage (MV) and local Low Voltage (LV) and network?
  • What other localized load is on the power system?
  • When will the power system be needed?
  • What are the requirements of the power chargers?

What is the impact on the grid connection cost?

 

By considering grid connection cost and charger utilization, the optimal locations can find. Charging infrastructure includes a broader set of factors. Particularly for high-power chargers, grid connection cost is dependent on location.

KINOUWELLPARKING has developed a range of ev charging products that will amaze you. You can simply add them to your business, or private area.

Advantages of EV charging station

Electric vehicles are becoming popular all over the world. However, before widespread electric car usage, a network of EV charging stations must create in order to reduce range anxiety.

Charging is a way for owners and managers to attract tenants who own their electric cars. An EV charging station is a highly visible way to a property or building’s management environmental values.

This may help to a green image that retains and attracts customers and tenants who share these values. Companies will add a new dynamic to their corporate branding by offering their service free of charge as many facilities currently do.

User parking and charging fee

Charging-station hosts have to generate revenue directly from people who use their station’s services.

The re-selling of electricity at a higher rate by the utility is not allowed in many parts of the world. Owners can collect revenue for charging through pay-for-parking services.

Using these types of systems typically requires the installation of advanced EV charging station products. However, it should be noted that to date, many facilities are opting out of charging for use of the station, and are instead providing it as a free service.

Employee attraction and retention

Buildings or companies that offer Fast charging station may be able to attract and retain employees who want to charge EVs during the day. In addition, it can be very important to many employees, even those who do not drive EVs, that their building or employer is proactive with transportation planning.

Every time that an EV driver visits a charging station, there is an opportunity to advertise. A station host could advertise its own products or services in this way, or sell advertising space to another organization.

Value of avoided carbon emissions

With a growing number of local and regional carbon-reduction policies, charging station owners may be able to benefit from the value of carbon emissions offset by their stations.

EV Charging Station: Maintenance and Service

During the warranty period, due to poor manufacturing of the product itself, or damage caused by normal loss of the device or failure to use normally, the production unit is responsible for the maintenance, commissioning or replacement of parts for the use of the unit, such as disassembly, impact, snoring, etc. damage caused by human behavior.

The production unit will pay for maintenance, commissioning, or replacement of parts.

What is a charging station and how is it characterized?

The column for electric vehicles is an electricity distributor through which it is possible to recharge an electric vehicle (van, car, motorcycle, and bicycle).

Charging stations can have several features including

  1. Location and accessibility: public, private open to the public, private property;
  2. Owner:energy distributors, car manufacturers, commercial entities, garages, etc.;
  3. Configuration: column, pole, wall box;
  4. Technical characteristics: power, type of electrical sockets, type of current;
  5. Authentication procedures: smart card, app, key, none;
  6. Paymentmethods: direct debit, tokens, free.

The context of the recharging infrastructures is therefore very heterogeneous.

 However, it is possible to refer to three main types of most recurring columns?

How do you charge an electric car from a column?

For public or private charging stations open to the public (e.g. customer car parks), Mode 3 or Mode 4 charging is mandatory for direct current columns.


To fill up with electricity from a column, the “ev-drivers” roughly follow the following steps:

  1. through an app,for electric mobility, the closest available electric station is identified and it is checked that it is not occupied by another vehicle being recharged
  2. once reached, park the vehicle at the column and authenticateif necessary (via app or manager card)
  3. the vehicle is connectedto the electric column through a suitable connection cable (generally owned by the driver)
  4. While the vehicle is recharging, you can move away(go to the bar, to work, go home, etc.) as the sockets generally have a lock (column side) which makes it impossible to disconnect the cable to steal it during recharging. If you leave, it is advisable to return in time to complete the recharge both out of respect for other users and for economic convenience (some payment systems are timed and not energy-based)
  5. once the recharge is complete, a confirmation by the user is required (via app or card) before being able to disconnectthe cable and restart

Technical characteristics of the columns and implications

The Fast charging station differs from each other from a technical point of view on the following aspects which can significantly affect the charging process:

  • Sockets available: there are different types of sockets in the field of electric mobility both on the column side and on the vehicle side. The standard charging stations provide type 2 (for cars) and type 3a (mainly for scooters) sockets which, through appropriate cables (and adapters if necessary), can be connected to electric cars which generally have type 2 sockets or type 1.
  • Maximum power:the public columns are characterized by a maximum deliverable power which has one of the following levels:
    • 3-7.4kW: slow charging stations that allow you to recharge between 20 and 40km in an hour
    • Equal to or less than 22kW: these are the size of the most frequent recharging stations and allow accelerated recharging of about 150 km in an hour which for different types of electric cars corresponds to filling up from a flat battery.
    • equal to or less than 50kW: fast charging stations allow recharge of about 300 km in an hour which generally allows you to fill up in about half an hour
    • over 50 kW: ultra-fast charging stations

It is important to underline that to use the column at maximum power it is required that the other 2 elements involved in recharging, i.e. the cable and the car, can work at the power levels offered by the column. The power at which the recharge takes place is always equal to the lowest power of the 3 which is often the one accepted by the car.

Two Different Power Levels of Fast charging station

 Vehicles generally have two maximum power levels accepted by the internal charger: one for charging in alternating current (3.7 or 7.4kW only in some models and more) and one for charging in direct current

  • Current type: most of the Fast charging stationsupply alternating current there are also direct current stations

Connector system: Which charging connector does my electric car have?

Depending on the vehicle manufacturer, different connector systems are used. In Europe, the type 2 plug is standard, with some Asian and American models still using a type 1 plug.

These include, for example, the first generation Nissan Leaf and the Mitsubishi Outlander. If you opt for a charging station with a permanently installed charging cable, you must ensure that it is also compatible with your vehicle. There are no adapter options here.

Graphic type 2 connector

Fast charging station with a type 2 socket, on the other hand, offers you full flexibility, to which the corresponding mode 3 charging cable can be connected as required. A charging station with a type 2 socket is the best choice, especially in public areas, e.g. in hotels or company car parks.

Charging station: what do I look for when choosing a manufacturer?

When buying a Fast charging station for your e-car, always choose a quality manufacturer that has been tested and listed by leading car manufacturers. In this way, you can be sure of compatibility with your vehicle as well as future updates, services, or spare parts. Find out which charging station manufacturer is right for you in our shop.

  1. Additional functions: What do I need?

With the rapid development of electro-mobility, the demands on the charging infrastructure are also increasing. It should be smart and compatible with other new technologies. Only a smart charging station can offer that. With it, you can use available smart functions and are well equipped for future needs.

Integration of a photovoltaic system:  With an appropriate energy manager, you can also use the self-generated solar power from your photovoltaic system to charge your electric car. Especially with recent feed-in contracts, the associated increase in self-consumption is highly profitable.

More about charging with PV power

Load management for electric cars:  Smart charging stations can be integrated into a load management system using additional modules. With the same connected load, several electric cars can charge at the same time.

The available power is automatically distributed across the number of charging electric cars. Above all, companies, hotels, parking lots, etc. with several charging stations avoid expensive power peaks through load management and effectively prevent an increase in the service price.

5. Installation of a charging station: who does it?

We generally recommend having the charging station for your electric car installed by a qualified electrician who is familiar with the requirements and standards for connecting a Fast charging station. Before you use an existing socket to charge your electric car, the electrical installation must be checked, especially in older buildings, to ensure that charging at full power is safe for several hours.

6. What are the costs for purchase and installation?

You can get a reliable charging station as a basic model for around 600 euros. Depending on the equipment and additional functions, the price can of course increase. A not insignificant cost factor is the professional installation of the charging station by a qualified electrician. The conditions at the planned charging location, in particular, play an important role here:

  • How far is the car park from the fuse box?
  • Are wall breakthroughs or excavation work required?
  • Can the charging station be mounted on the wall or is a stand required?
  • Is there already a line that can be used or do you need to lay a new cable?

How to save money on Fast charging station installation?

Basically, we recommend making the installation “future-proof”. If a new cable has to be laid, design the cross-section for a 22 kW installation right away, even if you don’t need it yet. This will save you additional costs in a few years if you want to charge an electric car with a faster charger.

Equally important are the electrical safety elements. Each electric car charging station must have its circuit protected with a circuit breaker. The RCD is already integrated into some charging stations, which can significantly reduce the installation costs. We have recorded the relevant safety criteria to be observed during installation in the installation tips for charging stations.

Depending on the charging capacity and the individual conditions on-site, you have to expect a total of between 500 and 2,000 euros for the installation. Use our checklist to better estimate the cost of installing a charging station.

Major Terms in the field of ev Fast charging station

Electric vehicles are a new trend globally. Because of this “new” point, many electric vehicle owners still do not fully understand the knowledge about electric vehicles. So, through this article, I will introduce everyone to some terms in the field of electric vehicle charging that you need to know.

What are AC and DC charging?

Surely when it comes to electric vehicle charging, you often hear about AC and DC. Essentially, electric vehicle battery chargers can be either external or internal to the EV. In case the battery is placed inside the EV, the charging process is called AC charging, in the case of the battery placed outside the EV, it is called DC charging.

More specifically, when the EV uses AC power, a device inside the EV is required to take care of AC-DC rectification and DC-DC conversion if necessary. The charging process is simple, but it requires plugging the EV into an AC outlet, then the car will be charged.

On the other hand, for DC charging, an AC-DC rectifier is an available part of the EVSE. Therefore, it is possible to supply DC directly. In addition, for DC charging, the time to fully charge the battery will be faster due to the weight restriction.

Charging type, charging level, and charging mode

Chargers are mainly defined by the capacity they can produce. There are 3 main types of EV charging: slow charge, fast charge, and super-fast charge. Fast chargers have 2 types of charging points, AC and DC depending on whether they use alternating current or direct current.

Slow charger

This is the most commonly used charger in the field of electric vehicles. The slow charger uses a standard 3-prong 13amp single-phase plug, with a single charge; the battery charge time ranges from 6-to 8 hours (depending on battery capacity). This slow charger is usually included with your electric vehicle purchase and is supplied with a charging cable with the appropriate connector and cable.

This type of slow charger is often used overnight charging at home or work because the amperage to supply the slow charger is only about 12-16A.

Summary:

  • Slow charger rated at 3kW, single-phase, amperage 12-16A
  • Use a standard pin socket
  • Time to fully charge 6-8 hours

Quick Charger

Fast charging reduces EV charging time to about half compared to slow charging by doubling the amperage to 15-80kW, fully charging time is only about 3-4 hours. This charger can be used for commercial purposes, often installed in shopping malls, and along vehicle routes. 3-phase fast charging, each phase provides about 7kW for a total receiving power of 22kW. 

One thing to note when using 3-phase fast charging is that it is necessary to balance the electrical load between the 3 phases to avoid phase differences when overloaded with phase wires.

However, this type is mainly used to charge electric trucks and buses that need a high-capacity charger to power the large battery pack of the electric vehicle.

The technological status of Photovoltaic–Electric vehicle (PV-EV) charging stations

The PV-EV fast-charging station is divided into different categories, which are PV-standalone charging systems and PV-grid.

From a practical point of view, the distinction between the two architectures is the inverter, which is added to the smart grid to link the station. The infrastructure contains the common components of each station, namely: bidirectional dc charger and inverter, energy storage unit, dc-dc converter provided with MPPT control, and PV array.

The design and control of the PV-EV charging system

We have compared and evaluated many types of research that contain the control and design of PV-EV charging systems. Moreover, this overview includes charging standards. The power converters’ topologies focus on the control of both PV–grid the adoption of vehicles, PV standalone DC charging systems to grid technology.

Fast charging aims to recharge EV batteries within a short period. It is similar to that gasoline refueling. The time for fast charging is about 20 minutes with 80% capacity.

Thus, the traveling distance of EV batteries can be extended. It provides that there are many charging stations on the way. The off-board fast charging module is the key to fast-charging stations, which can output 35 kW.

The current ratings and corresponding voltage are 20–200 A and 45–450 V, respectively. As both current and power ratings are so high, such facilities are installed in service centers or supervised stations.

Fast charging enables EVs to have a driving range similar to that of conventional vehicles. It creates adverse impacts on our power system, namely high current demand superimposing and harmonic contamination on the peak-hour consumption. It is against the principle of demand-side management.

Summary:

  • Fast chargers usually have a reception capacity of 7-22kW, 1 phase or 3 phase
  • Charging an EV usually takes about 3-4 hours
  • Sockets of this type are usually installed by electricians, so the cost will be higher
