Charging infrastructure for high-voltage vehicles

A high-voltage vehicle can consume between 3.3kW and almost 10kW of electrical power while the high-voltage

battery is being charged. 

Example: In Germany using household mains socket (230V alternating current)

Normal household sockets have one phase and supply a maximum current of 16A at 230V.

-

P_{(single-phase)}= U x I 

= 230V x 16A [1VA ~ 1W] 

= 3680W = 3.68kW (absolute)

Due to electrical losses during charging (power dissipation), the value must be corrected to 3.3kW of the absolute

value.

If the high-voltage vehicle can be charged via a

socket with three phases, the electrical power that is

fed to the high-voltage battery is tripled. As a result,

the charging process is shorter compared with single-

phase charging.

-

P_{(three-phase)}= 3.3kW x 3 

= 9.9kW

In future, customers will be able to chose from three

charging possibilities for their high-voltage vehicle.

A connection check should be performed on site before a customer purchases a high-voltage vehicle with external

charging facility. It should be ensured that the household electrical mains can supply a constant high current for

charging the high-voltage battery. This stress test is currently performed by an electrician. In future, this could

become a task for the dealership.

The charging unit is fully set up at the customer's house and connected to the household mains. Ideally the unit

should be installed as a three-phase charging facility. However, this option depends on the electrical infrastructure

that is available at the customer's house or flat.

In many cities, electricity suppliers offer high-voltage vehicle users the possibility to charge the high-voltage

batteries at public charging stations. This charging option is three-phase in most cases.

When the high-voltage vehicle user is travelling, he can charge the high-voltage battery via a conventional

electrical socket. The current rating can be changed with the selector housing in the centre of the cable. 

This serves as protection so that the electrical mains are not overloaded. In addition, the housing contains a

residual-current-operated circuit-breaker. This charging method takes longest to charge the high-voltage battery.

Across the world a large number of different connector types are used for a wide range of electromobiles like

bicycles, light vehicles, scooters and wheelchairs.

During the talks between German car manufacturers, a standard connector type was agreed on.

home, the charging cable for public networks and the

household cable for charging with any conventional

socket.

Charging can be 3-phase using 380 volts or with just

one phase using 230 volts. 

The connections L1, L2 and L3 are the phases with

230 volts each. The phase shift of 120° results in an

effective voltage of 400V.

During the charging process, the vehicle body is earthed via the mains connection (protective conductor) for

electrical safety. 

The safety contact of the charging connector activates the charger in the vehicle. The vehicle cannot be driven

when the cable is connected.

The connector contacts are scoop-proof (IPXXB protection class). In addition a leading pilot line is

fitted. 

This connector and the charging socket on the vehicle allow a charging process to be performed

safely without further measures in any weather.

Remote services

Using a mobile telephone as a remote control for the electric vehicle

A mobile telephone that has Internet functions similar

to a miniature computer is called a smart phone.

Thanks to its Internet capability and thus the

networking connection, the phone can be used to

operate certain electric vehicle components. 

An additional application (app) allows the smart

phone to be linked to the vehicle.

The user can use the following features of the app:

-

Expected range of electric vehicle

If the high-voltage battery is being charged, you can monitor the charging duration

Status of vehicle: locked, windows closed, charging connector connected

Set climate control requirement for interior

Delayed charging to use cheaper night-time electricity

Vehicle information like average consumption in kWh/100km

Display of convenience consumers in kWh/100km

Plan the remaining electrical range of a hybrid vehicle 

This function will become useful in the future when city centres, like London, may only be driven through with

zero-emissions vehicles (ZEV), i.e. vehicles without direct exhaust gas emissions. 

For certain hybrid vehicles with an electrical range of about 50km, route planning is possible via the telephone.

Think Blue.

lk

“Think Blue.” sees Volkswagen dedicate itself to the question of how individual mobility and sustainable behaviour

can be reconciled.

An electric vehicle does not produce any direct emissions when driven. The high-voltage battery needs to be

charged to move the vehicle. The electrical energy from the external charging source needs to be produced with

renewable technology in order to rigorously implement CO₂reduction measures. The generated energy is used

highly efficiently by an electric vehicle. 

The aim is the conscious use of resources by humans.

“Think Blue.” goes one step further.



This scheme invites us to think further and shows that ecologically sustained behaviour is possible without sacrifices

and can also be fun.

“Think Blue.” lives through dialogue with customers. The slogan refers to the “Think small” campaign for the Beetle

in the sixties. Back then mobility for everyone was addressed with the Volkswagen Beetle. At the web page

www.volkswagen.com/thinkblue, anyone interested will find information on fuel-saving driving styles,

ecological sustainability and conscious use of resources.

The creation of awareness starts with small things. 

Does the television standby function always have to be active? 

Maybe it is enough to open a window instead of switching on the air conditioning system? 

Can I save more energy by opening the blinds during the day and switching off the artificial lighting? 

Are driving pools more efficient in terms of CO₂savings? 

How can I save water at home?

Recognising savings potential is not the source of sacrifice. 

The aim is fun while saving: the “fun theory”.

The technical scope from the following concepts is combined under the umbrella term “Think Blue.”:

-

“BlueMotion”

“BlueMotion Technologies”

“EcoFuel”

lk

“Blue TDI”

“BiFuel”

“Hybrid”

“blue-e-motion”

“Think Blue. Factory.” Low-emissions automobile production

The “blue-e-motion” brand stands for electromobility within the framework of the “Think Blue.” idea.

The cornerstones of “Think Blue.” are:

1. Environmentally compatible products and solutions

2. Environmental behaviour

3. Environmental commitment

Towing an electric vehicle

The drive wheels of an electric vehicle are coupled to the electric motor via the differential and the reduction gear.

This connection cannot simply be separated. If the drive wheels are rotated, the electric motor will also rotate.

If the high-voltage system is activated and ready to drive, the system will recognise the towing procedure as

regenerative braking. 

The high-voltage battery will therefore be charged by the towing procedure.

For this reason, towing electric vehicles on their own wheels is not permitted. 

The towing procedure should only be started once the electric vehicle is no longer in running condition. 

If the high-voltage system is deactivated, the rotation of the electric motor can cause temperatures that damage or

destroy components. Furthermore the rotary movement in the electric motor produces an inductivity that acts as a

resistance to movement of the vehicle (like a bicycle dynamo).

You are allowed to slowly push the electric vehicle out of a dangerous area, however.
