The electrical system for the installation of charging solutions for electric vehicles is subject to compliance with certain regulations and consequently to special safety measures.<\/p>\n

We assume that the power supply circuits of the recharging systems<\/strong> and the relative protection devices must comply with the requirements of Section 722 \u201cPower supply for electric vehicles\u201d of the CEI 64-8 standard.<\/p>\n

Charging modes 3 and 4 of electric vehicles, defined in the CEI EN 61851-1 Standard<\/strong><\/a>, require a dedicated power supply and charging equipment that incorporates the control and communication circuits.<\/p>\n

Special security measures<\/h2>\n

The legislation provides for special measures for the safety of recharging points:<\/p>\n

    \n
  • the protection of each connection<\/strong> point with a differential device with rated intervention current not exceeding 30 mA, type A, together with a suitable device that ensures the interruption of the power supply in the event of a fault current in direct current (DC) higher than 6 mA, or a type B differential switch;<\/li>\n
  • each connection point<\/strong> must be powered individually by a terminal circuit and must be protected by its overcurrent protection device (this means that the terminal circuit must power only the system designed to charge the electric vehicle).<\/li>\n
  • the sizing of the circuits<\/strong> must take place with a factor of contemporaneity and use equal to 1.<\/li>\n<\/ul>\n

    Surge protections<\/h2>\n

    As regards the protection against over voltages<\/strong> of atmospheric origin or manoeuvre (paragraph 722.443) it is strongly recommended that the power supply circuit of the charging point be protected with a surge limiting device (SPD), this to prevent possible damage to the electric vehicle. or to the charging system.<\/p>\n

    Utilization factor<\/h2>\n

    Utilization factor is the ratio, expressed as a numerical value or percentage<\/strong>, of the maximum utilization of a circuit<\/strong> or groups of circuits within a specified period, concerning the total installed power of the circuit.<\/p>\n","protected":false},"excerpt":{"rendered":"
