Electromobility has reached the mass market and sales gures for electric
cars are increasing continuously. Charging infrastructures conforming
to applicable standards are required in order for the vehicles to be
charged optimally, eciently and safely. The DISTRELEC company, your
very capable partner for electromobility, stocks a well-rounded range of
intelligent and scalable solutions for setting up charging infrastructures.
The various charging plugs
The Type-2 charging plug has become established in Europe and is
standardised in accordance with IEC 61851. The Type-1 plug is also used
in the USA and certain Scandinavian countries. Both plugs are available
as a pure AC voltage variant (which charges slowly) and also with the
addition of solid plug-in contacts (plug CCS Type 2) for charging with DC
voltage (fast charging, also known as super-charging). The fast-charging
plugs are compatible, so that it is always possible to charge purely with
AC voltage, i.e. slowly. Slowly at home and fast when on the move.
The various charging modes
Charging mode 2
Charging mode 2 is the simplest way to charge an electric vehicle. The
charging cable is plugged into a commercially available domestic socket
outlet, generally 13 A, single-phase AC voltage. The electronic charging
circuitry, also known as “IC-CPD” (In-Cable Control and Protection Device),
between socket outlet and electric vehicle, controls the charging process
and checks current ow. This solution can be used as soon as a vehicle is
charged over a longer period, for example overnight. This charging mode
can also be used as a “makeshift solution” since a domestic socket outlet
is generally available at all times. The charge cycle takes longer accord-
ingly owing to the low current ow.
Charging mode 3
Charging mode 3 charges only with AC voltage but uses far higher
currents (up to 63 A). Both single-phase and 3-phase. There are two
variants of this mode:
Charging mode 3, case B
In case B, the charging cable has a vehicle charging plug at one end
and an infrastructure charging plug at the other. So the charging cable
does not have a xed connection to the charging station and can thus
be carried on board the vehicle.
Charging mode 3, case C
In case C, the charging cable has a xed connection to the charging
station.
Charging mode 4
Charging mode 4 complements charging mode 3 in that charging can
also be performed with DC voltage and very high transfer currents
(200 A and above). Generation of this DC voltage means a more complex
charging infrastructure. AC voltage is converted to DC voltage using
a rectier. The current leads must also be sized accordingly. Standard DC
charging stations have power rating of approx. 50 kW.
This allows electric vehicles to be charged in minutes.
