3 Definitions
Clause 3 of EN 61851-1 applies with the following additional definition.
3.1
vehicle charging control unit (VCCU)
system embedded in the electric vehicle which controls the charging parameters of the off-board charger
4 General requirements
The d.c. electric vehicle charging station shall be connected to the electric vehicle so that in normal
conditions the charging function operates safely, indoors or outdoors, causing no danger to persons or
surroundings, even in the event of carelessness that may occur in normal use.
According to 6.2 of EN 61851-1, the EV charging mode is only mode 4 and the supply cable and
connector are permanently attached to the charging station (case C).
In general, this is achieved by fulfilling the relevant requirements specified in this Technical Specification
and compliance is checked by carrying out all relevant tests. General requirements for the d.c. charging
station can also be found in EN 60439-1.

station.
The reference operating temperature range is -20 °C to 40 °C. In some countries, different temperature
range may apply.
The extreme limits of -25 °C and 60 °C are admissible during storage and transportation, and should be
taken into account in the design of the device.
