Abstract: A system and method for electrical vehicle charging includes a plurality of outlets, at least one parallelization switch, a guarding wire running in parallel along a DC path formed by outlet switches and at least one parallelization switch and comprising a plurality of outlet guarding switches, a plurality of current sensors, a plurality of voltage sources and at least one parallelization guarding switch, and a control device connected to the current sensors. Each voltage source, current sensor and outlet guarding switch is associated to each one outlet. Each outlet guarding switch is associated to one outlet switch. The control device is configured for opening at least one of the outlet switches and/or the at least one parallelization switch when at least one of the current sensors measures a current greater than zero.
