Abstract
The application relates to a charging system, including a number of m chargers each adapted for providing electrical energy to charge an electrical vehicle, whereby m is an integer and m≥1, a number of n outlet ports each adapted for electrically connecting the electrical vehicle, whereby n is an integer and n≥2, and a switchable connection matrix device including a number of n outlet port switches each adapted for electrically connecting at least one of the m chargers to one of the n outlet ports and, if m>1, a number of m−1 charger switches each adapted for electrically connecting two of the m chargers, whereby the switchable connection matrix device is adapted for detecting a short-circuit between at least two outlet ports and/or for generating a fault signal if the short-circuit between at least two outlet ports is detected.

A charging system, comprising:
- a number of m chargers each adapted for providing electrical energy to charge an electrical vehicle, wherein m is an integer and m≥1,
- a number of n outlet ports each adapted for electrically connecting the electrical vehicle, wherein n is an integer and n≥2, and
- a switchable connection matrix device comprising a number of outlet port switches each adapted for electrically connecting at least one of the m chargers to one of the outlet ports and, if m>1, a number of charger switches each adapted for electrically connecting at least two of the m chargers, wherein
- the switchable connection matrix device is adapted for detecting a short-circuit between at least two outlet ports and/or for generating a fault signal if the short-circuit between at least two outlet ports is detected, and
- the outlet port switches and the charger switches are each controllable by a switching signal and wherein the short-circuit is detected and/or the fault signal is generated based on the switching signal.
