4. ELECTRICAL GRID CONNECTION
4.1 Electrical connection for charger without storage
The electrical connection is the responsibility of customer and should be done by qualified person.
The charger should be connected to an electrical grid:
3 Phases plus neutral (3P + N + PE)
400/230 V +/- 10%
50 Hz
Neutral network TT or TN, (IT under option)
Notes:
1.
The short-circuit current at the connection point has to be below 10 kA.
2. The loop impedance of the earthing system must be less than 20 ohms.
This connection must be protected upstream by:
- A head switch capable of handling at least 120 A to electrically isolate the charger in case of
maintenance.
- A tetra polar circuit breaker (MCCB), curve D, 120 A, suitable for 54 kVA equipment.
- A Residual current device (RCD) capable of handling at least the maximum current of the above-
mentioned circuit breaker with a sensitivity of 300 mA; type A, HI, S.
- The electrical connection is made internally on terminal X1 (see APPENDIX 1) by feeding through
the power cables using the channel provided for this purpose (see APPENDIX 2).
- It should be ensured that the section of the power supply cable is sufficient. This section is
defined according to the maximum rated current of the charger, the voltage drop and the
installation method.
Note:
1. Size according to the regulations and standards in force in the country of installation.
Thus, to calculate the required minimum section, be aware that a fast charging station has a maximum
primary current of:
-
50 kW model: 87 A per phase with power factor > 0.98
